Client asks for redesign to look more like XYZ site.
I deliver a redesign to look more like XYZ site.
Client wants the site to look more like his old site. But different. Gives extensive instructions on how to design his website to his liking.
At some point, I think I'll be owing him money for his design/dev services, not the other way around.
What is it with these people?5
My room fan broke today....
And it has been hot for a while now in The Netherlands, so every store I went to sold out.
So I made one myself :)
On a side note, my pc temperature has never been lower :')20
For those who were wondering, since my last post had some people who seemed interested, here's my progress on my 8-bit computer. I've got the clock on the left hand side, and the 2 8-bit registers on the right hand sign. (The power strips in the middle are going to be used as a bus)9
It's the biggest satisfaction to know that Wix means wank in German!
"why not do it yourself" just adds to it.6
*builds a DIY 3.5mm audio wire out of metal jacks, 28 AWG electrical wire, and Ethernet wire coat as a sleeve*
*measures its resistance by doing 4 wire measurement*
(4 wire measurement explanation => https://youtu.be/L9q5vwCESEQ?t=260)
Turns out to be 800 milliohms for this wire.. well that's crappy. At such a low voltage like what the sound card puts out (30mV peak-to-peak at best) that's gonna heavily attenuate the sound, no?
*measures another audio wire that I bought a while ago with the same method*
3.2 fucking ohms, and my test at 1A significantly heated up the wire too. Turns out that this DIY contraption is 4 times better than the commercial ones out there... Sometimes you really have to dial down to what common standards you're building your own stuff against. And it's relatively easy to build too.. awesome! :)
Well, all I can say is that I'm satisfied ^^11
1024 points of soldering !!
Wasn't expecting that when I began, but it's quite interesting and the result will look amazing ^^
I'm making a LED matrix from 0, controlled by an Arduino, it will look really good when it's finished, I plan to use it to display notifications, clock, sound spectrum etc...
What do you think of it ? 😇15
Fun fact: "wix" of wix.com in German language phonetically translates to a vulgar word for masturbation. Not only describes my feeling towards services like these but also gives new meaning to the "do it yourself" mentality.8
Young enthusiastic computer science student here. Was quite a long time silent reader of rants and other posts. Love this community. Today my raspberry arrived, looking forward to work with it and I just wanted to share my happiness!7
Does anyone else fantasize about giving up programming and go live in a jungle or doing other things that require more physical effort?
I've been learning carpentry, farming, DIY power generation etc. The goal is to be self-sufficient and go live in a fucking jungle someday. Or legally buy some cheap land far from the city and automate the shit out of it. No wait, I'll just live there as a normal farmer and write code if I feel nostalgic or something.
I think anyone other than me could have expressed that better.16
My arduino mega just arrived. My home will become a slightly smarthome (All diy) so excited.
Best part it will not touch privacy12
TL;DR: check polarity before plugging your DIY circuits into others!!!
*goes off to watch some Lucky Star and drink some booze*
*notices phone battery dying after 3rd pint*
But my charging cable that Huawei delivered with this thing is way too short... Well that ain't no problem, I can make one of my own 😎
But I'm tipsy.. sound I really enter the workbench in this state?
*goes off to build a charging cable anyway*
But what was USB-A male connector's polarity again? Oh, there's the fan's USB connector that I've made in the past. Let's check on that one. So, left is positive and right is negative?
*solders the wires on*
Snip, strip, stick, done! Well that was easy. I guess that all those failed soldering attempts and lost pads in the past as a means of training did pay off in the end!
*plugs phone into Raspberry Pi media center through new charging cable*
Strange sounds coming from the speakers.. well that's odd. Reverse polarity or maybe the Pi can't handle a 1A load from my phone?
*plugs phone into the 5V 5A charging hub that I've made earlier*
That oughta do.. current limits should be no more in that thing.
*charging hub makes high-pitch noise similar to the Pi speakers*
Definitely a reverse polarity, isn't it :') let's check on the Gargler...
Oh shit! It is a reverse polarity mistake!!! Should've checked this earlier >_<
*resolders wires properly*
Alright, finally done.. as I'm writing this post, my phone's charging from the Raspberry Pi through my fixed charging cable now...
Lesson learned. Always check on the internet what the pinout is before soldering anything, don't solder while tipsy, and be fucking grateful that this phone has reverse polarity protection in it.
Nexus 6P with all its shortcomings regarding power delivery and battery management, luckily it's got reverse voltage protection features built-in. Otherwise it might've costed me my phone. Always double-check before plugging anything into something else!!!5
You haven't actually *begun* to learn anything until you've shouted FUCK THIS SHIT (or some variation) out loud at least once.
The anger is what makes it stick in your memory.10
so I compiled and printed some mini stickers for my laptop and thought I'd share them with the community. Great if you want to be subtle or don't like big stickers clogging the looks of your precious babe. All images are high res so you can expand them if you'd want that.
(stickers use black background cuz my laptop is black and its easier to cut out but you can change that)
For editing:(plz don't judge for using odp/pptx I was restless and only had openoffice to edit)
Spent all day on this.
Debugging hardware is fucked man...
Wanted to make a devrant logo like always (its my Hello world to test my CNCs now).
And.... When I finally had the machine calibrated... The pen stopped working lol.
I'll just continue tomorrow, it's finished...
Probably gonna use a few times and make a bigger one.27
Pro-tip #2: wear a suit to work twice a week if you want people to take you seriously.
Pro-tip #3: get some sort of hosting and learn to DIY with Linux and no docker. If you know how to properly run your own version control, email, and web server you will be a step ahead of other developers in terms of secondary skills and resume and you’ll have a website and an email address to prove it.35
Just finished my CNC.
Lots of problems but it works... More or less.
Need better steppers and other drivers. But I did it, learned a lot, did lots of mistakes, and don't get me started on debugging hardware...
Z axis unfortunaly can't even pull the motor up lol.13
Started learning vim... It feels like a DIY IDE where you have to find half of the parts on the internet...7
What do you think of my DIY - Headphones? You need a rubber band to put them on but the sound is amazing!4
Read the console message...
Go to Lucidworks.com/vision
Click on next, until you get something funny5
Launched a CMS-site for a customer, created a 5-page "manual" (with screenshots) on how to update basic things like adding/removing employees from the site. One week later, I receive an email: "Could you please remove Paula from our site?"... Sure, it'll take me 2 minutes and you'll be billed for half an hour instead of you just RTFM!6
Today's project, turning my diy convencional milling machine into automátic.
Status: it works.
Features: motors are to slow.
Solution: need better motors.10
When the last battery of one of your phones die. And you don't want waste more money with a new one.
But you need to perform a backup.3
TIL: The IKEA effect is a cognitive bias, that lets you think, stuff build by yourself is more worth then stuff build by others
Does that sound familiar to anyone?2
I'm working on the scariest looking electronic thing that I've ever built.
It started to terrify me more today...17
Do you know when you think "Oh that doesn't look too hard. I bet I can do it in no time"?
That is how I felt when I saw the DIY 3D printer kit Anet A8. It's only 150€ on gearbest so that is pretty cheap.
The reviews said it takes about 3 - 4 hours to build and I though "Ok I am a computer specialist and engineer so 3h sounds reasonable".
When I bought it from gearbest the first problems started: 5 days after the estimated shipping date the packet was still not on its way. After I fucked the support up, it finally arrived 3 weeks after the estimated date.
When I took the first look, everything seemed to be fine except for some small scratches but for that price that is not a problem.
So I started to build the printer at about 14:00 and even if some random sites in the manual were in Chinese I felt confident to get it done in a view hours.
And then it started to get really fucked. The first problem was that 2 screws were unusable and I had to use my own screws instead. The next problem was that the manual was just in the wrong fucking order at some points and I had to reverse multiple steps to get it right.
But the most fucked up thing: There should have been 2 threaded rods with a length of 345mm but the rods had a length of 310mm which was nowhere listed in the parts list. So I had to go buy some aluminium rods to fill the gap temporary so that I can at least go on with the build before getting a replacement. And I could go on and on and with the problems but the point is, it is now 19:30 which is about 5.5 hours after I started and I am still not fucking done with this.
So what have I learned?
Cheap Chinese hardware is good, but only as long as you don't have to assemble that shit yourself.2
Four hours of work.
You think you write spaghetti code? I write spaghetti wires.
H-Bridge dual motor tester for stepper motors.
Speed is controled by pot.
H-bride are L293D.
My third board, and the first that won't go to the trash.
Question. With the baterry off the motor continues spinning with the 5v from arduino.
My question is, is the L293D suposed to do that? Or do I have a short circuit somewhere that is giving power to the motor? Meaning it can burn the arduino.
Runs a 12v stepper from a CD-Rom driver perfectly at 5v from the arduino and actually starts to act strange when I turn the 12v on. (maby the circuit it's adding 12v + 5v?)25
It flies it fucking flies !!!!!!!!!!!!!!!!!
I built a quadcompter from few ordered parts (DIY quad)
And damn its a fucking beast.
Its still tiny but damn flies like a rocket.
Waiting for bigger props and then lets race.12
So I just received this second DSP5005 DC-DC programmable power supply. Time to make an enclosure for the thing!! 3 power supplies totaling at around 1kW, and 2 variables connected to the 50V 10A one, through external banana wires (I want all of this to be modular). No biggie, take measurements for the AC-DC supplies, add in the variables on the front, and cut it out.
So, I went and did just that. Now my 500W (50V 10A) supply is a bit larger than the others, and it's got a fan. So I figured, well then probably my 24V 8.3A (200W) and 12V 15A (180W) supplies could use some cooling as well. But how am I going to achieve passive cooling without a spacing between the supplies?! So I thought of some spacer design. It had to be out of wood, and I had some 4mm MDF and some IKEA parts around. So, 4mm MDF for the plate and 8mm wood spacers from IKEA for the spacing. And some super glue to hold it all together.
Weighing my power supplies against a 1l bottle of milk, it seems like my power supplies are ~500g. Great, so the top spacer would take 500g and the bottom one 1kg + the weight of the top spacer.
I ended up building one plate with 6 spacers in it yesterday, until I got too tired. Then I placed my entire weight against it, 20kg at least. It didn't budge. Pretty good for something that's only designed to withstand a 1kg load!!
So, I made something good with only a 10x18cm piece of MDF, some garbage from IKEA, and most importantly a bit of a brain. Something that can handle 20x its designed load no problem. Manufacturers, is it really right to produce shit when I can beat your manufacturing processes big time without an assembly line?!5

Decided to upgrade my hardware a day after wk119 ends. Oof. I'll post an update once the first part (monitors) arrives, but here's a before pic in the meantime.
Monitors: 3 different brands at 3 different sizes/resolutions. Left to right: 1920x1080, 1680x1050, 1440x900.
Mic: Neewer NW-800 with a U-PHORIA UMC22 interface.
Keyboard: A DIY Nyquist kit from keeb.io with Canvas XDA keycaps.
Rubber duck: I prefer a fuzzy kitten.3
Cnc v0.5 done.
Still needs a few fixes but I can engrave my DevRant Hello World.
Needs a bigger table (and Visor), new spindle (fried the one I bough, using a very old scarvanged for now)

My room fan broke last week, and they were sold out everywhere.
So i build one myself (last rant), but after a while it just blew hot air.
So after some work I have this :) Now it even has RGB :')
I haven't ranted for today, but I figured that I'd post a summary.
A public diary of sorts.. devRant is amazing, it even allows me to post the stuff that I'd otherwise put on a piece of paper and probably discard over time. And with keyboard support at that <3
Today has been a productive day for me. Laptop got restored with a "pacman -Syu" over a Bluetooth mobile data tethering from my phone, said phone got upgraded to an unofficial Android 9 (Pie) thanks to a comment from @undef, etc.
I've also made myself a reliable USB extension cord to be able to extend the 20-30cm USB-A male to USB-C male cord that Huawei delivered with my Nexus 6P. The USB-C to USB-C cord that allows for fast charging is unreliable.. ordered some USB-C plugs for that, in order to make some high power wire with that when they arrive.
So that plug I've made.. USB-A male to USB-A female, in which my short USB-C to USB-A wire can plug in. It's a 1M wire, with 18AWG wire for its power lines and 28AWG wires for its data lines. The 18AWG power lines can carry up to 10A of current, while the 28AWG lines can carry up to 1A. All wires were made into 1M pieces. These resulted in a very low impedance path for all of them, my multimeter measured no more than 200 milliohms across them, though I'll have to verify and finetune that on my oscilloscope with 4-wire measurement.
So the wire was good. Easy too, I just had to look up the pinout and replicate that on the male part.
That's where the rant part comes in.. in fact I've got quite uncomfortable with sentences that don't include at least one swear word at this point. All hail to devRant for allowing me to put them out there without guilt.. it changed my very mind <3
I've tried to plug my DIY extension cord into it, and plugged my phone and some USB stick into it of which I've completely forgot the filesystem. Windows certainly doesn't support it.. turns out that it was LUKS. More about that later.
Windows returned that it didn't support either of them, due to "malfunctioning at the USB device". So I went ahead and plugged in my phone directly.. works without a problem. Then I went ahead and troubleshooted the wire I've just made with a multimeter, to check for shorts.. none at all.
At that point I suspected that WanBLowS was the issue, so I booted up my (at the time) problematic Arch laptop and did the exact same thing there, testing that USB stick and my phone there by plugging it through the extension wire. Shit just worked like that. The USB stick was a LUKS medium and apparently a clone of my SanDisk rootfs that I'm storing my Arch Linux on my laptop at at the time.. an unfinished migration project (SanDisk is unstable, my other DM sticks are quite stable). The USB stick consumed about 20mA so no big deal for any USB controller. The phone consumed about 500mA (which is standard USB 2.0 so no surprise) and worked fine as well.. although the HP laptop dropped the voltage to ~4.8V like that, unlike 5.1V which is nominal for USB. Still worked without a problem.
So clearly Windows is the problem here, and this provides me one more reason to hate that piece of shit OS. Windows lovers may say that it's an issue with my particular hardware, which maybe it is. I've done the Windows plugging solely through a USB 3.0 hub, which was plugged into a USB 3.0 port on the host. Now USB 3.0 is supposed to be able to carry up to 1A rather than 500mA, so I expect all the components in there to be beefier. I've also tested the hub as part of a review, and it can carry about 1A no problem, although it seems like its supply lines aren't shorted to VCC on the host, like a sensible hub would. Instead I suspect that it's going through the hub's controller.
Regardless, this is clearly a bad design. One of the USB data lines is biased to ~3.3V if memory serves me right, while the other is biased to 300mV. The latter could impose a problem.. but again, the current path was of a very low impedance of 200milliohms at most. Meanwhile the direct connection that omits the ~200ohm extension wire worked just fine. Even 300mV wouldn't degrade significantly over such a resistance. So this is most likely a Windows problem.
That aside, the extension cord works fine in Linux. So I've used that as a charging connection while upgrading my Arch laptop (which as you may know has internet issues at the time) over Bluetooth, through a shared BNEP connection (Bluetooth tethering) from my phone. Mobile data since I didn't set up my WiFi in this new Pie ROM yet. Worked fine, fixed my WiFi. Currently it's back in my network as my fully-fledged development host. So that way I'll be able to work again on @Floydian's LinkHub repository. My laptop's the only one who currently holds the private key for signing commits for git$(rm -rf ~/*)@nixmagic.com, hence why my development has been impeded. My tablet doesn't have them. Guess I'll commit somewhere tomorrow.
(looks like my rant is too long, continue in comments)3
I just wanted to show what i built.
Devrant meet projector clock.
It uses atmega and one generic 7x5 LED matrix and some rtc chip.
It projects current time on the wall opposite in scroll manner.
I also want to add internet connectivity to it next. So as to show reminders and slack notifications. Work is on for that thing.
(If you want to build one here is the code
My security knowledge is so bad. But I don't know where should I start.😖
My coworkers know about this, so I don't get involved on related topics.🤤
Last time I asked same question, someone gave me link, and it all about DIY welding metal tubes into a security door.🤦♂️
Any better suggestion?13
I’m a perfectionist, not a great trait to have as a developer, needed to channel that energy so started DIY at home where I can make things ‘perfect’. Immensely satisfying, and gets it out my system.3
So I made this simple lamp that shows what is current build status on Jenkins CI.
- Change color depending on Jenkins build status
- Automaticaly turn on/off if user is logged on Hipchat
- Beam effect if somebody makes coffee
- Unicorn effect if food is delivered
- Big red arcade button that can send random message to somebody on Hipchat
Here's a life hack for you.
If you're ever in need of a whiteboard for drawing/sketching, grab a few white a4 paper sheets, a roll of transparent duct tape, tape both sheets together side-by-side. Cover both sheets with tape
et voila! You have yourself a portable & foldable whiteboard!
The more sheets you involve, the bigger the whiteboard will be :)
P.S. It's very handy!!14
This thing is too good. I think it's the best hack I've ever seen !
3 weeks of search, but now, I have a miniUPS with solar and dc input for my raspberry pi Zero with cam.
I have developed a little ble4 iOS app to monitor all voltages and relay states.
All this shit from China, about 50$ except rpi and cam.
What you think?9
everything mounted, was going to connect Z and motor...
And the fucking X stepper isn't working...
The plastic piece that made the steps is overused and can't handle the weight :(24
Target for airsoft.
The prototype bullseye didn't survive the trials but it works. Just need to upgrade to wood.2
So in near future I'll buy myself some new nice headphones to hear amzing music alongside coding and the help of my new expensive DAC.
They problem is that I need to voicechat and the famous Modmics cost at least 50€.
So I made my own Modmic for 0€ out of an old headset (free) and a suction cup.
Drilled holes and put some new bolts in my laptop to fix the hinge. Kind of looks odd but I like it😂11
I need ideas.
What's the best use for several old, moderately crap laptops (<= 4GB RAM) I have lying around? I'm using one as a minecraft server because 3GB ram is enough and the Pi isn't, but past that, I'm pretty stuck. They all work, mostly, have CD drives and mostly free hard drives.25
I didn't see a post for it but a decent book bundle for Raspberry Pi and Arduino is on Humble Bundle at the moment.
HUMBLE BOOK BUNDLE:
DIY ELECTRONICS BY WILEY
Get Learning Python with Raspberry Pi, Electronics For Dummies, and more!
One of the best things about having a basic knowledge of mechanical engineering, and access to shop floor tools.
I don't have to pay for stuff like docking stations 👌6
Since I mostly see frameworks to use with G-Code in Arduino CNCs I'm gonna make my own framework, where you don't need to know G-Code and the code is executed by Arduino code.
The code would include a template to define steppers steps and such.
Would include a library to work with different stepper shields.
Would this interest to anyone?
I'll provide a full example with stuff to learn for any amateur working with CNCs or that want to work with one. If you're not interested, thank you for reading, you can stop here.
This framework would only use incremental coordinates and will work for basic forms, drilling and such.
Coordinates can be relative/incremental or absolute.
Lets say you have a square with 10mm, (top coordinates: (X=0,Y=0) to (X=10,Y=10).
think your drawing this square.
Third Line (...)
Absolute is a fixed point (coordinate)
Relative is a distance to move (not a coordinate but the distance and direction)
So, to cut a square with a TR10 (end mill with radius=5, diameter=10)
// You don't place + in positive values
// The tool always cut in the direction of the tool rotation, meaning on the left of the material.
Z(10); // Security Distance
XY(-5,0); //Compensate the diameter of the tool in radius
Z(-1); // Z=0 is the top of the block to mill, in this case. Z=0 can also be in the bottom
Y(15); //Second Point
X(15); // Third Point
Y(-15); // Forth point
X-15; // Fifth Point
Now we have a block with 1mm depth. If you use a while or for you can repeat the sequence for x=n passages, change the value to Z for the depth and your done.34
Got this motor here... What do you think it's voltage is?
Tryed 12v, didn't even move...14
Doing a full rewrite from some DIY spaghetti framework: when it can't find a search query it returns "false" with the status code 200, the same php file responsible for querying an external api is put into all sorts of named folders, so e.g. a user that is in the results page X can continue searching on the same URL, instead of doing proper url rewrites or ajax calls to the one in the root directory, html is thrown into every other php line, a DIY sort function for a numbers array that fails to sort 0 before 1 and that all is just a 10 minute review, can't wait to see the rest.2
Thinking of making my own laptop stickers:
- Buy letter size sticker paper
- Print multiple logos/icons on sticker paper
- if needed, laminate the front side of the sticker paper with a thermal laminator (wife has one)
- Cut the stickers out
I will report back with the results and pictures later. I assume they will end up a bit thick if I laminate them.7
Who else hates tutorials.
They are made with so much text and outdated code that it’s better to write the thing needed by yourself and stack overflow.🤔4

Project: pool cleaner.
Hey guys. So here's the story I mounted my pool one month ago in a very hot day, but the weather is getting freakyer with each year and this was the first sunny day.
But I fill my pool with water from a well. Chlor takes care of bacteria but the damn algy are a problem.
First part: pump the shit out.
First test: not working properly.
- Reason? Buie keeps the dirt from reaching the motor;
- Hazardous: motor must be always under water
- Main problem. Pump is ment to sink in the bottom and pull water out, so only has one exit, the entry goes directly to the engine.
Workable? Turned a snail into fine dust, needs a hose with a buie that goes directly to the motor.
Just having fun... I would be in the pool if I had cleaned it last week2
"Why would you make your own when you can just get one for like $30 online?"
One of the single most disheartening things I've heard from a peer.
Seriously, are you really so incompetent and dependent upon other people's work that you can't even come up with a single reason why I would do this?! Don't you dare try to call yourself an engineer. Call yourself a cheat, cause that's the only way you passed that class.
Even after explaining that making it yourself is one of the best ways to learn about/understand it, they still couldn't understand.3
Weee both projects from yesterday went perfect...
Usual most of my projects end up fucked up because I want to do stuff I don't know how to... (well, I'm learning so I don't get frustrated, just pick up another idea).
Air cooler for power people V 1.1 works perfect. Today we will get almost 40 C and I feel the cold air in my face.2
Finally had a weekend to myself to work on some projects. I got my hands on a Sonoff switch. Did a manual flash of some new firmware and got it setup on my crappy old washer to do a little DIY smart home upgrade.
Always nice to get to do a personal project 😊 Just wish I had time to tinker more.3
Today was my first day in a Molding Company (CNC operator)... IT was fine, I barely could hold on physically but I did it :D In less than two weeks I'll be operating my 3 new machines like a PRO.
But that's not the full story... I came home, my dad calls me, and has a mold drawn on paper (2D) for me to model in 3D and print... lol.
I'm proud, not just because I got a new job at first try, now just because my dad asks me to build stuff, but Also because my dad is a DIY guy with lotssss of experience... And now he's the one asking for help, opinions, how to do something...2
Today's finished projects :
Mini vacuum cleaner:
Works. Just need better patles to be really effective.
Portable lighter wire solderer :
Works but the flame must be always on. Takes time to heat. Good for a tight spot and you can buy the tools for it anywhere.
Many if the coil is more open... I'll check on beta 2 (not quitting yet)4
Free Time + RapsberryPi + Alexa + alcohole = Smart Bartender
Fuck yeah I love the future4
Last today's project (I think).
The history: a good cover for this pool costs as much as the pool.. The fuckers are selling the pools cheap and accessories really expensive.
7 euros cover that uses the sun to heat the water. Added hocks but no need, only really needed the weights. So... 1 extra hour spent, but I like my hocks :D5
A bit random, but I decided to put a perpetual clock inside my illusion mirror with a bunch of LED's while it was slow at work today xD1
Best boss I've had was when I was collecting recycling materials as a truck driver.
The company mostly employs unliterated people that can't get a job anywhere else, so It has lots of dumb, jealous people who made his life miserable.
Still, he's so good with people that he could filter it all out and we had a great relationship even in such a poisonous environment.
He was really sad when he told me I wouldn't have my contract renewed. He allowed me to work from 5 am to 2 pm so I could finish my 12grade class (high school) at night and I fell asleep one day. The company does not renew contracts if you miss even one day. When people talked bad about each other he would just nod and do nothing or descalate the situations.
Well, I'm off to help my dad again :( he's the one who gave me the taste for DIY, but fuck his projects take so much time. Were repainting a motorhome :D
Oh man setting up postfix and dovecot (plus things like rspamd) is a pain in the ass.
But it's worth it, having your own mail server is just quite a good feeling.
Now I just need to find out how to get it to pass the spam filter of Google, despite the server and the DNS zone being well-configured (better than my school's mail server according to tests, but that one still manages to pass. I have no idea why.)9
I could finally find the time to hang with my wife and watch a show. Two minutes in a customer calls to tell me his site is fucked. "I didn't change anything". Well, who renamed the style.css file in the WP theme then? Argh!1
Management proposed to work with external freelancers, to "pick up speed so we can release these new designs sooner". We agreed, but of course we (the home team) can't have time to review their work because we need to develop other new features and bugfixes and such...
Weeks later, turns out that their changes are largely incompatible with the work we have been doing on the main branch. We are now rebasing/rewriting huge chunks of their work, probably taking as much time as it would have cost us to develop the design ourselves in the first place.4
So after a pretty packed day of family time, DIY, play dates and parenting, I managed to squeeze in a couple of hours of game dev... now to get up in 6 hours to go to work.1

So, this is my first led matrix using a 74hc595n, I did all the connections right, isolated the cathodes (-), and when I tested, I only connected one cathode (to test one row, when almost all the lights turned on, in all rows doing a chacing... So I disconnected the negative wire and it still works.
One led in the arduino blinks (L).
GND is only connected to the shift register
All the rows light up doing a colum chase when there is no negative.
The surgery appears to be a success !
When you are too poor to afford proper medical care, you have to DIY..
I got myself one of those USB microscopes so I could examine the site in more detail. (Hard to reach and see as it was on my bottom !)
Anyhow, I successfully cut out the lump myself, didn't bleed to death in the process, and it hasn't grown back after several months, so I call that a success !
The wound site is now healed.
Didn't use painkillers, so it hurt a bit..9
I've found this tutorial on getting a google free android phone (tl;dr: lineageos, fdroid&yalp, etc.)
It probably isn't news for most of us in here, however a handy beginner friendly guide to give to friends and relatives.
The downside: it's in german.13
Hey, I need ideas. Keywords: DIY, IT cabinet, cooling. I hope I'll catch your eye :)
So I'm doing my apartment renovation. Complete renovation, 100% everything is remade. Soviets did a lot wrongs but one thing they did I like - storage compartments below ceiling (like double ceiling.. does it have a name in English? I often see them in garages). So I tore down the old compartment and created a bigger new one. I've moved some of my IT devices up there: router, switch, raspberry, etc. Now... it's okay while it's autumn-winter, it's bearable up there. I'm worried temperatures might get very high during summer.
Compartment is not that big, smth 1m x 2 m x 0.5 m.
Any ideas for cooling? I could set up a vent fan to circulate air but it's hardly a cooling. Also not very effective. A/C is not an option as the compartment is too far away from outter walls. Also A/C might be somewhat overkill :) 5 minutes ago I've remembered I had an in-car portable fridge-like thing that could keep drinks decently cooled during summer. I'm wondering whether it would work? Any ideas where could I get this cooling mechanism (what to even google for? :) )?
Is there anything better in the market? DIY? I'm not willing to spend a fortune for this idea (one more reason A/C is an overkill)2

If you want to be a dev, don't buy a house. Or if you do buy a house don't do DIY. Or if you do the DIY, do it badly so you don't have to do it again.
This was my project for today.
Power supply, 5v USB 25A x2; 12V 10A x2; extra power standard cables to power HDDs and such.
Plus a sand paper whatever it's called :p
Ps: Need to know how to power it without the standart power supply, with cables direct to the brush motor pins. Anyone knows? Have arduinos, l293, easy shields, uln2003a... Would one of this work?
Hope you guys like my 🤪 ideas5
TL;DR one year on as a react dev, I want to go at it self employed, humbly seeking advice as this community seems to have its fair share of knowledgeable freelancers.
I have 1 year professional experience now as a Meteor, React and Apollo developer
The dream is to become self employed. I figure a good market would be small businesses that want a website that are more featureful than a diy wix site.
Only I am more of a developer than a designer, so rely heavily on things like Bootstrap or Material ui. So I wonder if Upwork, Fiverr or simply my own freelance website would be better.
Also want to build own projects on the side to monetize. Bigger dream would be to be client-less and develop and sell personal projects.
Seeking advice from those who are self employed. Am I dreaming too big?
Shall I keep the office job for a bit longer then take the plunge? Or do you think I can just go for it. Are there lucrative areas I am missing?
Thanks in advanced8
Been receiving packages every day but today I good good shit..
Ideias for me to try?
4 relay module, 4 mostef board, finally the gears for the motors I'm scraping, and more mostefs. My mom is saying that I have the mailman for myself lol2
One of the big ISP/entertainment companies dug up the roads a few months back and laid fibre optic cables (cutting through a power cable in the process but that's another story).
Recently had someone turn up at my door to chat about their services. All sounded very good, I took a card and gave it some thought and did some research.
So, it'd be a little cheaper than my current provider (FTTC setup). It'd be faster for downloads, slightly slower for uploads (I want fast upload). IPv6 is only on their business packages. I use IPv6 a lot. I also have several static IPv4 addresses.
It would involve getting a cable in to where my equipment rack is, and one to where the TV is (which I spent ages building a TV unit with power, network etc.)
To record/watch TV in another room with their service, I'd need to pay extra. The service just provides HD channels that I can already get, unless I pay more. At the moment I have MythTV handling all the recording of TV shows I want, and Kodi to play them back on different TVs, via CAT6 I spent ages installing into the walls.
Then there's the uncertainty of how nicely their equipment will play with my relatively complicated setup.
I decided, it isn't worth it really for me. I would have to change a load of stuff just to end up with what I already have... But with more limitations.
Anyway, the guy turned up again a few days later, I told him of my decision and away he went.
Since then I have been visited by 2 other employees of this company to try to sell me the service.
It is probably great and convenient if you are not like me and DIY all your home network and media distribution setup...
Also the ISP I'm with is quite small. They are very knowledgeable and friendly and I can get through to someone quickly if i phone. What I use meets my needs, so I prefer to support the smaller company in this case.
So... My parent's house is 40 years old.
I'm cleaning the corners... and my father as a DIY guy and a man that was never afraid to learn and update, there is so must useful junk, but also soooo many card boxes. He never throws them away, in case he needs to return the item.
So... I've been cleaning a 3 shelf open closet.
- have around 8 bags of cardboard, paper and newspappers for recycling.
- plus 2 bags of plastic.
- 4 bags filled with books for the local community center.
- a bag full of electronics to salvage.
And this only in 2 rows...
Man how could he store so much stuff in there I don't know, but this ends up being fun.
Also, one printer to salvage. :D
When it's over I get to own the shelf to store my stuff :D3
I have too many geeky non-dev activities. I don't know which is the geekiest...
Built a server rack out of bits of spare wood (going to rebuild and improve it in future). Wired up the entire house with network cabling. Didn't need to, just prefer not to use WiFi for things where possible. Also ceiling mounted a PoE WiFi AP for things that have to use WiFi (e.g. smartphones).
DIY built a rack mountable Pi shelf with faceplate.
Configured a dedicated TV tuner/PVR PC used by Kodi running on Raspberry Pi for a couple of TVs (all diskless/network boot).
Got a colocated server running in a data centre for running various VMs on for different things. Run my own email, webserver, DNS, VPN, voice chat server, various other stuff.
Gradually getting into electronics, which overlaps with dev a bit.
Sometimes I play games. I built a dedicated VR PC which occupies the smallest room of the house.
Unsure which is the geekiest thing!3
It's true what they say.
You don't mess with hot glue without burning yourself.
It would be funny if I didn't have my pointer fingers burned up lol.4
We had this team project to do in my second year at university. In C btw. My team consisted from 3 members. We had about a month or so to finish it. So of course we started 2 weeks before the submission. Well... I started. Those two didn't give damm about it at first but after I pushed them to do something one of them tried to code this simple function. It was supposed to check if the opptions from command line could be combined. His fuction had around !!200!! lines of code 😲 but he swear it was working. I was skeptic so i tested it. waaaaaait for it... it didn't work... the very first combination I tried that should not be accepted passed his awesome test 😱 I gave him another two chances. Result was the same.
I was furious. I had my part to do with little time to test someone else's code... So I desided to code the whole project on my own. Then I told my "coworkers" that they either pay me for it or they will be without any point for this project. I earned 80 € that day 😀😎
Btw my test function for those opptions had less than 10 lines 😁
FML. I have to draw system diagram at 12:00 am and the worst part is I don't even have an app that does that so I need to use my Design app to draw this shit full DIY style. This is not my fucking job fuck you...
I wish my project lead go hell and fucking Satan puts his dick in his ass. MotherFucker then you will understand my pain ASSHOLES3
So, I have a new printer for parts.
Question, what type of glass does scanner uses? Does it have some special treatment or is it normal glass? Thanks8
Why do I make everything so expensive. I'm not a hardcore enthusiast, but at the same time I wont settle for "mainstream" and so I do weird unique things that end up costing more than they should
My mech keyboards are all DIY, I've spent $150-200 on 3 different occasions for 3 different keyboards. I think I'm settling down, but boy that was rough on my wallet.
Now I'm working on a custom workstation build, but I can't just use any normal tower because I ain't no normie. I want it to be SFF/portable so I'm planning on spending $250 just on the shoebox case (DAN A4-SFX). That's probably the most expensive part, besides maybe the GPU. Current plan is R7 1700 or 2700 with 16GB, RX 580 8GB, and 1TB NVMe, around USD$1200 total maybe11
Thank to this UPS driver ... i'm not going to get my package (laptop screen) until Monday evening.
Express Priority shipping $35.xx or whatever that is down the drain.
Never had this issue with Fedex and 100's packages delivered.
This ends the rant.3
Since I already got fired I don't have problems start uploading my tutorials at the middle of next month...
First... Where should I put them? I'll Make a written tutorial, and Video tutorials, so I need a good cheap web provider and some places like Instructables, but I would like the possibility of gaining some money with some of the stuff.
Btw, Already have one... Maby some can help?
I have an unmounted HDD (3 pins or 4 pins, must work: With no driver and no extras... I know it's possible, just can't find the Information. Then I'll make a video on how to make the same thing with chips (not MCUs) and finally with MCUs). Since there isn't much information around there about this, would be a great 3/4 video tutorial.
I know I can make it work without the board or drivers since I already saw two Indians doing it on youtube, just couldn't understand them and the video quality is shit.
Shit will probably my first Video, but I need to find ways first.
One of the tools I already made: https://youtube.com/watch/...
The problem is using a 300w power supply for tools that require so low power.
Ever visited https://www.instructables.com ??
DMNNNN I just can't leave... So many cool Ideas...
I don't have anything to do with the site, found it yesterday while searching for arduino stuff, and MANNNN .... It has the best pratical tutorials I ever saw... Not like most, where they teach you the basics...
Most sites, first arduino APP, light a Led
Instructables, First App, Instructions with pictures and videos on how do connect the Arduino, install IDE (this is the most basic tutorial after all). then the tutorial, Light 4 leds and do a lightshow...
I'm In Love
Btw, new project, got my old Niko Dc Car working again, after like 30 years...2
## building my own router
I hoped things would go more smoothly :)
Anyway, my new miniPC easily accepted CentOS 8 - no fuss here. And I've got to say - I love CentOS8 so far! Shell has amazing nifty tricks, UI (gnome3) is also snappy, video/audio/ethernet,.. everything works.
What I did NOT expect is hardware being off. Well okay, the price was low - it was obvious smth is not right. But still.. I decided to build my own router so that I could swap wifi card whenever I want. So that I could run my own network services in there. Turns out - the card swapping is not as easy as one might think.
I got the AX200 WiFi6 card for that very purpose. But once plugged in the OS can only see it's bluetooth module. Weird... What's even weirder is that even though the card is PCIe, the OS uses btusb module to talk to that device. What? USB?? emm.. What??
And there it is. After opening it up again I noticed that the mPCIe area is marked with a label: "USB WIFI / WWAN". USB? Does that mean this PCIe slot is wired into the USB bus? Not impossible I guess.
Googling for a "pcie wifi over usb" or smth like that brought me to one reddit (I think?) where someone wanted to build a DIY wifi mPCIe -> USB adapter and someone else adviced hime that (for some reason) at best he could only get bluetooth working (hey! just like me!). It's got to do smth with pcie channels and USB being too weak to handle all that load, or smth.. IDK, I'm not a HW guy.
Well that sucks then! I have a mPCIe slot that does not work as a PCIe. Shit! So I guess the best I could do is to plug back in the same wifi card that came with the device. It smells like 2003 - supports only g protocol. Fine, let's try that. Maybe I'll find a way to work around this mPCIe limitation later on (USB adapter or smth... except there are no USB WIFI6 dongles yet :( ). So I plug it back in and start turning it into a router. Disable NetworkManager, configure static NCs' settings, install dhcpd, hostapd, bind and others. Looks like all is done! Now it's time to start it all. systemctl start hostapd --> FAILED. wtf? journalctl says it could not initialize a driver. umm okay? Why? Forums say I should airodump-ng check and kill whatever's using that device. Fine. airodumo reveals avahi and wpa_suppl are still using it. kill, kill, GOTTA KILL 'EM ALL!! Starting hostapd again -- same shit... wtf?
My gawd... That shitty network card does not even support AP mode :( I mean.. My USB wifi dongle for 2€ supports 2x more modes, is faster, has better range and is easier to work with than this old tart!
Yeah. That was an interesting day. When enfironment engineers break my testing environments at work I'm glad I have where to spend my time now.
BTW any ideas how to bypass this mPCIe nonsense? Come on, there are USB GPUs out there.. Why can't they make a USB (or dual-USB if they really need to) mPCIe adapter?11
Searching how to (insert dev related skill) then after that getting only adds shown for places that do professional dev work. No, obviously I am trying to learn the shit myself not willing to pay someone else, in fact add a sync my bank account to search just so google can comeback with results filed under you are too poor to pay for shit here are the diy results you poor dumb fuck using free wifi. :)
I did ask in a DIY woodworking group, but the message got removed, I guess it was too outlandish..
So, maybe all you DIY woodworky like folk here might be able to offer some suggestions..
I'm building some wardrobes, and got to the door part, but not being flush with loads of cash means I have to find cheap ways to do doors.
Suggestions welcomed. :-)
My current thinking for doors roughly 3ft tall by 1ft wide, that come in pairs and slide is to use hardboard for the main material, a front layer, and a back layer, that's about 3mm thick each.
I don't have much of a gap for the doors, so they have to be thin..
Hardboard is cheap, and the plan is to varnish it.
For the wood structure between the sheets, I notice Birchwood lollypop sticks are cheap, 2mm thick, so 3 layers of those would give me another 6mm, making a total of around 9mm.
Stuff all that into some very cheap stainless steel wheels meant for glass, running in wooden rails.
TLDR; My laptop's CPU temperature becomes +90 C when I compile stuff.
I have two different laptops that have the exact same configs and OS. I use one as a desktop and the other one is just for school stuff and homework. As you might think, the one that I use as a desktop is looking like a mini desktop. I was into DIY stuff while ago so I made a custom case and separate the LCD as well. Don't ask me why though.
Today I was working on a personal project that has relatively complex build config. Since the compilation always took 3 to 5 mins I went to the kitchen for some coffee. Bumm. My laptops fans are working in a way that one can think they're in the airport. Seriously. All 8 cores are +90 C when I checked them.
The next thing I did was compiling the same project on the other laptop which I used for school projects. It took like 20 mins to compile but the max temperature was like 50 C.
So, in the end, I'm still trying to find the reason for that behaviour.10
Yay, I got my RTL-SDR, receiving ADS-B and WFM radio and ATC is easy, any ideas what I should try next? (please, only suggest what the antennae in the kit can handle, I'm not planning on making any diy antennae soon)10
My older brother introduced me to linux and android custom roms when I was like 11. So I flashed my old sony Ericson phone with custom roms from xda and tried Ubuntu live CDs on my mother's old 40gb hdd laptop.
But my introduction to programming was when I saw some videos about the raspberry pi on YouTube.
I was like 14 and programmed basic scripts for my raspberry pi in nano over putty or notepad++.
At first I didn't even knew to intendent but in the process of my first project (Python sunrise alarm clock with tts) I learned many valuable things about Python and Linux/Debian.
The years after that I learned more with my now multiple RaspberryPIs, Arduinos and other hardware.
So in conclusion RaspberryPIs, the diy/open source community and especially my brother introduced me to programming.
Build a server Rack DIY
But after I finished the work, I realized, that my conversion from inches to cm about 0.5cm to short is
Not finding a way to make money posting YouTube videos all day long. Like that woman who uploads DIY “how to make slime from Elmer’s Glue” and makes over $100,000 every month from ads and merchandise. Or that 5 year old who makes millions per month in ad views playing with toys on camera and his parents upload it to YouTube calling it a “toy review”.
I wanna be a YouTube star for just a year so I can retire.5
I just can't believe in what state are the "leading" eCommerce systems. It just gives me depression and I'm totally desperate. :(
After 10-15 years one is xml hell, another is insane modules DIY administration, and the last one is bugy slugish mess. Try to guess which one is which.3
Just finished my first tutorial ever!!!
"Cheap poly pocket/plastic sleeve hack for storing small electronics/stuff... "
I wanted to make tutorials for a long time, but due to a burnout, I've been unable to finish any project.
Yesterday I was trying to find a solution to place all my resistors in one place, and I found it... Then I tought.. I never saw this hack on the internet... It's simple, easily explaining, this could be my first Tutorial.
So here it goes:
1st - It's an Alpha product, just finished with the grammar
2rd - Pictures may be changed later when I get my workbench and good light
3rd - No styles yet, so don't complain about the lack of CSS, but it's already readable.
When I get a few more made, enough to desert a page on itself I'll CSS everything (So I can create a common theme) and release it to the public... maybe I'll get a few bucks with a few Ads
This alpha release is only for DevRant use. I would appreciate comments, improvements, ideias and tips
Thanks to @forE , @oudalally , @ewpratten , @Stuxnet , @j4cobgarby , @BashouT , @Plastic pocket and other in: https://devrant.com/rants/1539595/...8
Am currently developing an app which uses an IaaS named Auth0. Great experience so far, reasonable docs, unlimited users, social login, sso and support for about $29/m.
After an inquiry from a customer to provide MFA, I contacted Auth0 to see what it would take to use this feature.
"We only offer this in our Enterprise plan which starts at $18k/yr."
Well, fuck me with a pitchfork and call me Bridget the midget. I'll code it my goddamn self.1

Could be fun
It's not necessarily code related, but ever since I was a kid in grade school, I've wanted a lab where I could solder and build and mix chemicals and build rockets and brew beer and blow stuff up and do all kinds of science that would ruin my carpet and/or otherwise go horribly wrong if done in my living area. One day soon (I hope), I'll have enough space to have a proper lab, just not today.
I daydream about that shit.1
I finally have a vServer again, now I need to fill it with 'life': secure it, build a small website and mailserver.
The main idea is to have some basics to look more professionell. I'd love any tip and idea how idk, save work before I run into stupid beginner mistakes, or things you had good experiences working with when you had similar tasks? :)
I hate those "simple DIY" instructables. Just had to build something I had to get. Found out one "simple DIY". It requires owning a power drill with a table mount. And a pipe threading machine. Yes, I surely have a drill mount for drilling thru some steel, I know how to use a CNC machine, and maybe have a little metal foundry in my flat. But hey, it's a DIY not 'go to nearest store and buy that friggin piece you need' so you should have prepared yourself for some difficulties.
It's not supposed to be easy!
I still wonder why the author not assumed everyone own a metal foundry, after all. It would be much easier for all of us.
And I ended using PCV, glue, and a spare bottle. Had to buy drill for glass, less than $3. Wasted few bottles to cut out what I wanted. Beer was quite good, thou.1

What’re good starter projects for a Raspberry Pi? I would like to get started on hardware and I’m inclined to install recalbox or retropi (cause I love video games), but I’d also like a diy project. Maybe I’ll make a VPN...14
Paid for a private school in my country (France) cause public isn't so great.
After 3 years, realize that it was more bullshit than school so continue to paid until the last year to get diploma.
At the end, I was on Udemy to buy lessons and learn. Was way much cheaper than my school but since it's hard here without diploma, I had to finish scholarship...2
"Can you make this quick change?"
"Yeah, but I'll need to change every page this thing is on and you told me this other project I'm working on is high-priority. Are you sure you want me to do this?" (Also this is a change you're capable of making yourself...)
"It shouldn't take too long, we need this done."
...if I thought it wouldn't take long, I wouldn't have brought it up.
what do you guys use to control your DIY CNCs?
I'm using UGS, Universal Gcode Platform, but it has a slight problem... doesn't work with functions.
Meaning, I just had to write a 75 lines program that could be an 8 line program If I could use loops and GOTO...
Also, what CAM software do you use?13
Aw fuck, I'm more retarded when it comes to Linux than I anticipated.
(Arch) Linux is like a nice, big framework where everything you need for the basic setup is already there, but you end up overlooking it and implementing it yourself.

If somebody wants to become famous for the work they do fast. Join DIY projects such as React-Native.
You can become so famous for developing a highly demanded component, since there arent many well maintained this days.
I guess it is the case for many new and fresh projects.

Huawei published an ad stating their Mate 20 Pro smartphone has been voted phone of the year 2018 in my country.

An eventful day:
Because of my recent amateur thermopaste application onto a heatpipe that connects a laptop CPU and a discrete GPU and *ingenious* HP ProBook engineering my Radeon graphics have fried yesterday.
On the bright side, got the Nougat update for my Samsung S6, with bright hopes that it will help restore the state of an unresponsive fingerprint scanner... nope, that is still broken.
Summer is near, exams finished, time for some DIY on used and abused tech! :D2

My dad wants to add security cameras in our home. I kind of want to go ahead and add cool stuff(like automation or something) to our house using this opportunity.
What I am thinking of right now is salvaging an old desktop with an Nvidia GPU to add face recognition and motion detection to the mix. I am also thinking I could get an Alexa echo dot or something similar and hook everything up. Another idea is using owncloud to create my own cloud.
What do you guys think? Any ideas or suggestions? Maybe a cheaper way to do stuff?7

I looked at my S7 edge and thought to myself... When am I fixing this goddamn screen?
It has been a few months now
And I'm not going to a shop if I can do it myself a lot cheaper.
I'm actually looking into how to repair it and what stuff I need, so far I know about b7000 glue to keep I water resistant after the repair, of course some prying tools, maybe a hair dryer, and of course the screen itself, anything missing or am I good to go?
Naturally, im gonna post rant if my repair fails...
