Fuck all those shitdesigns that interface with their LCD using flat graphite cables!
USE FUCKING COPPER WIRES ALREADY!!! At least those things can take a small fucking tug of gravity during disassembly, unlike that micron-thick graphite junk which fractures even more easily than my goddamn toe did!!!
And as mentioned on Hackaday (https://hackaday.com/2012/09/...), repairing it is hell. How much does it cost to make a decent copper wire.. I can buy those things for like 20 cents from AliExpress, so don't tell me motherfuckturer that you can't. And these copper ribbon wires last on ya, AND can be repaired with a simple soldering job. Unlike this FUCKING GARBAGE!!!7
Just found a 1000kV arc generator on AliExpress.. huehue :v
1 megavolt? That's the usual voltage level on lightning bolts. And with air's breakdown voltage of ~15kV/cm (could differ depending on humidity), you'd need nearly a meter of distance between the prongs *and* be able to achieve an arc between that distance without having shit arc internally, before you could ever reach 1MV. Yet arc generators' prongs are usually within 1cm of each other. I'd give it 10kV at best.
Also, they're generating the voltage of a lightning bolt for €3.65 apparently.. way too good to be true. Even components able to handle 10kV are quite costly, and components having a breakdown voltage of over 1MV is completely unheard of. I'm gonna buy one of those puppies to see how the circuit is designed and to zap the shit out of those bloody mosquitos in here - the only women that love me :'( - but I wouldn't be surprised if it just boosts the output voltage up to whatever until it can arc and short out. Completely unregulated of course.. which is fine but eh, I doubt that any of those components are rated for 1MV so probably the regulation is in smoking components acting like fuses when the prongs are too wide apart :v
As for the purpose of this rant.. nothing in particular really. Perhaps it'll educate some, I don't know. Just wanted to put it out there :)
Also if you'd like to watch some video material about this, you may find ElectroBOOM's coverage interesting: https://youtube.com/watch/...34

I think that I've found the reason for this Acer motherboard's refusal to boot up now. Apparently this featureful piece of shit expects "something" on its ID pin as well.. and why ID pin you may ask? I reckon that it's because of "certified replacements". Because you know, if it doesn't come from our shitty factorias it's gotta be shit, right?!
How about no?!! You Acer really aren't the only ones capable of producing a fucking lithium battery! And did you ever think of the edge cases where you may want to feed a lab bench power supply's voltage into the phone to mimic the battery and troubleshoot the bloody thing? Because that's what I initially wanted to do, instead of that Doogee battery. The only reason why I didn't is because the supply is currently charging up another lithium cell that I salvaged from a donated (broken) Samsung tablet, and is taking longer than expected.
Point is, if you receive the appropriate fucking level of angry pixies, YOU SHOULD FUCKING USE THEM AND BOOT UP ALREADY!!! Regardless of whether it's some sort of certified fucking Acer component or not! Somewhere between 4.2 and 2.7V stable should be good enough regardless of what produces it!
At least AliExpress sells these batteries for about €4.5, and another €2 for shipping. Considering that I can buy batteries with this capacity for €2 a pop and free shipping, this would better fucking work. Especially since I'm buying an overpriced battery of which almost half the cost is fucking shipping, just for a stupid "certified" controller that' I'll also have to put between the board and any pixie wrangler or angry pixie containment device that I use to power this shitty board. Acer, you motherfuckers!!!1
So I have that custom-made wifi router I've built. And it uses a USB wifi adapter with AC (wifi5) capability - the fastest one I could find in AliExpress.
I set it up a while ago - the internet access works fine, although speeds are somewhat sluggish. But hey, what to expect from a cheapo on Ali! Not to mention it's USB, not a PCIe...
A few days ago I ran a few speedtest.net tests with my actual AC router and the one I've built. Results were so different I wanted to cry :( some pathetic 23Mbps with my custom router :(
This evening I had some time on my hands and finally decided to have an umpteenth look.
nmcli d wifi
this is what caught my eye first. The RATE column listed my custom router as 54Mbps, whereas the actual router had 195Mbps.
I have reviewed the hostapd configuration sooo many times - this time nothing caught my eye as well.
Googling did not give anything obvious as well.
What do we do next? Yes, that's right - enable debug and read the logs.
> VHT (IEEE 802.11ac) with WPA/WPA2 requires CCMP/GCMP to be enabled, disabling VHT capabilities
This is one of the lines at the top of the log. Waaaaiiitttt.. VHT is something I definitely want with ac -- why does it disable that??? Sounds like a configuration fuckup rather than the HW limitation! And config fuckups CAN be fixed!
Turns out, an innocently looking
made a world of a difference!
connect to the hostapd hotspot and run that iperf3 test again, and... Oh my. Oh boi! My pants fell off -- the speed increased >3x times!
A quick speedtest.net test deems my custom router's download speeds hardly any worse than the speeds obtained using my LInksys!!
The moral of the story: no matter how innocent some configurations look, they might make a huge difference. And RTFL [read the fucking logs]
In the pic -- left - my actual router, right - my custom-built router with a USB wifi adapter. Not too shabby!8
I love my Nexus 6P but goddamn do I hate its battery. Shuts down randomly at 25%, lasts only half a day, and a lot of other crap. So I want to replace it, bought a new battery from AliExpress but didn't buy any tools for it.. so I'll have to make do with what I currently have. On iFixit I found that the replacement process is apparently quite difficult as it's glued in (God I fucking hate that) and can only be safely removed by heatgunning it (which I don't have a heatgun for). Are the results worth the risk of breaking it? Is it possible to pull it out while cold, without too much risk of breaking stuff or damaging the battery? I've got experience in disassembling 2 previous phones and one of them had the battery glued in as well.. and I didn't break the battery (in fact I'm still using it) but it was very difficult.. and this is my daily driver. So yeah 😶21
A month or so ago this manufacturer of soldering equipment contacted me with the request to make a video about a review unit (a soldering handle) that they'd send to me for free in exchange. Initially I was really pumped about it - company would send me free stuff!! - but fast-forward to today and I realized how terrible a choice I've made by accepting that offer.
See, that handle is worth only €40 and I've spent so much time on the bloody video material already that it'd make my "pay" expected to be close to €1/h if not less. I feel like I've been exploited, especially since I don't even like the handle's design and am not using it. It's just collecting dust, making my work essentially free labor.
I could return the item but that's gonna cost me a fuckload of money, I could pay for the handle and cut my losses that way.. or I could do the review anyway and end up feeling very bad about that company. Or I could tell them to fuck off and lose a supply chain for my soldering equipment.
I have no idea what to do about this..
Oh and the fact that the correspondent in that company has the worst Chinglish skills imaginable, the communication skills of a toddler and is also super indecisive (they asked me to make a YouTube video first which led me to assume a video format for YouTube, but instead they want to put it on their fucking AliExpress product page, rendering my existing video footage useless!) doesn't help either.. I hate that shit company. Fucking leeches!
Anyway, what would you do when you're in a position like that?6
*decides to take another look at the Arduino Mega and LCD*
*suddenly realizes that this LCD controller that I bought has a different pinout*
"Alright, let's look at the seller's product page and they better have a pinout for this fucking thing"
*tries to log into AliExpress*
"At this point I don't even know anymore if it's China that fucked up again or whether this is another feature from the Facefucks"
"LOG ME FUCKING IN ALREADY YOU PIECE OF SHIT!!!"
And honestly, if I want to start a project, I want to work on the fucking project. I don't want to have to deal with all this shit instead!!!2
that feeling when your new toys from aliexpress get delivered earlier than expected... i feel so happy unpacking those sensors, capacitors, heat sinks, microchips, breadboards and all. i feel like i have a geeky shopping addiction, i probably won't have the time to play with them from all the work and other personal projects, but still i hoarded enough electronics to invade the world with a drone army in case i have a few weeks me-time.5
I just noticed that my desktop still has a DVD-RW in it that I never used.. which led me to think, I've got here like 5 DVD-RW's as well as 5 CD-RW's, but I never use them. Are there still any uses for them? Long-term backup storage for example? I've heard somewhere that data rot can happen over the course of a few years.. but would it really be a problem? I mean I've had these for over a year already and they look healthy to me. That said, they've never been used and just sat on the top of my desk in their enclosures all the time.
FWIW, I'm having 10TB of storage (as well as some other smaller stuff here and there.. maybe 500GB or so) in various hosts and 3 mirrors, so the need for backups is already fulfilled.. it's merely a curiosity of mine as in "ah, I still have these things huh".. so yeah.
I think that I've bought these DVD's for something like €6 for 5 pieces in a local store that doesn't specialize in this sort of thing, so I'm fairly certain that I could get them for cheaper elsewhere.. think the likes of AliExpress etc. Would they be a viable technology to maybe still invest in over hard drives for long-term storage purposes, considering that the cost of a hard drive these days is only €50 for 1TB? But I guess that tapes would be better for this purpose, no?9
You do know that "why do I need you if I can copy-paste code from SO?" joke floating around, right? Today I had a real-life situation perfectly illustrating it.
So I bought a set of parking sensors. Cheap ones, from AliExpress. Prolly the cheapest ones I could find. Installed them w/ engine turned off. All seemed fine. Cleaned it all up, got ready to go, started the engine and beeeep beeep beeepeeeeep beepp ..... beeeeeeeeep.
Tried unplugging/replugging them one-by-one to find the faulty one. Nada. Apparently they all were false-alarming. They must all be bad, bcz they seem to work well w/ engine turned off (ignition on) and only false-alarm when engine is on.
Allright, I'll get a new set next weekend, a more expensive one and replace them again.
There goes my €20 and another week basically w/o parking sensors (car length is >5 meters, so sensors do help a lot).
Today I spend a few hours removing my rear bumper again, replacint all the sensors, wiring, etc. Tests show promising results - all sensors seem OK even w/ engine on! Close it all up, start a car again and.... beeep bep bep beeep beeee..eeeeppp.
Another 30min-hour goes by while looking for a possible culprit. And I found it. The fix could did not take longer than 5 seconds. Apparently a wire feedint the sensors' controller was too close to sensors' wires. All I had to do is to push that wire a lil further from the controller with my index finger.
I could have saved €30, a week of time, half a day of work if I only knew what wire to [literally] poke.
- I need heat shrink tubes
- go to aliexpress, find the one set I need, order
- receive them to my PO, use a few of them
- I needed parking sensors
- to to aliexpress, find the set I need, order
- the parcel arrives in my country, on its way to my PO
- Today I visit a random site
Conclusion: AI is great at knowing what I have already bought and suggesting the exact same items I've ordered. Because if you've ordered them once you're likely to order them again, right?3
Any idea how to make a fan in an HP laptop spin at lower temperatures? The fan in my Pavilion dm-1 only starts spinning when CPU reaches 75°C and enters full speed when the GPU also becomes 75°C. Which is strange because this CPU and GPU are one and the same thing.. an APU. And overheating freezes often happen at around 75-80°C.. which isn't too much of a headroom really. I'd rather have it kick in at 50-60°C already, but would like to avoid using the power of the soldering iron for it.. I've already lost a fan to that previously (current one is a spare part from AliExpress). Granted, my soldering experience was much less back then.. nowadays I can probably even solder 1206 SMD packages comfortably. But I don't want to risk it, and I've got experience with custom kernels anyway.. are there any fan speed governors in the kernel that you know of?
FWIW, fancontrol doesn't seem to be supported on this laptop, and neither is pwmconfig. Perhaps I'll have to stick to the electronics method after all? Given that it's just a 5V fan, I guess that I could feed it power by tapping some power from a USB rail and controlling its speed from an ATtiny85.. but inside the laptop there isn't enough space for that and I don't feel like freeing this hardware out of its laptop chassis yet (though that is on the list). Either way running at 60°C under no load is terrible.. some HP certified enganeering "feature" I guess...4
What the fuck is wrong with all those chinks on alibaba? They post their product at $100 a piece then when you try buying from their store, all out of a sudden its $450 plus $600 shipping (for a 1.5kg box, mind you)
How the actual fuck can those morons assume someone is retarded enough to fall for that kind of shit? Are we all (westerners) so fucking dumb in their eyes?
I can buy that shit from a reputable brand like Samsung @ retail stores right here for less than what they try charging for their no-name garbage that at a closer look feels like it barely survived a fucking nuclear disaster and I don't even have to wait for 912375819 weeks for their army of starving slave kids to actually build the product, nor another 2-3 weeks for DHL to decide to bring it in, nor another 2-3 weeks for the parcel to clear customs (usually in one piece but hey sometimes accidents do happen, like an officer's drunken elephant trips and smashes through the whole fucking pallet) (sorry sir it was like that when it got here)12
when you divide the products you sell into different categories, i dont think "human hair" is a good category.
this actually gives me an idea. i kinda wanna create a redesign plan for aliexpress app tbh cause i dont like its UI/UX.9
Speaking of.. What in your opinion would be an appropriate way to warn someone about security problems, like db passwords in git?
I once came across dozens of extremely sensitive services' infra accesses: alibaba/aliexpress, natuonal observatories, gov institutions, telecomms, etc. I had dozens [if not hundreds] routers' and firewalls' credentials along with addresses. I tried one to confirm validity - it worked. I wanted to warn them but did not want to get in trouble.
If it were servers, I'd set a motd or append some warning messages in .profile. But not sure how to do it for non-server devices
what would you do? How would you warn them?
P.S. Deleting that record was a smart move, buddy ;)
p.P.S. Sorry, wrong category... Can't edit now :(7
First thing in the morning... Buy 50 stickers from AliExpress
Today i got probably the stupidest and fucking coolest idea ever.
And i aint joking.
So what is the idea ?
Well i was wondering when im mainlining devices why dont i build my own board
I mean could be fun right ? RIGHT ?
Why ? Well i was casually looking around aliexpress and Allwinner V3s showed up. Its a tiny SoC with 64MB RAM and some other things.
So i was like why not build board about it. Seems like it runs mainline already. Less job for me. Uboot is ported. Again less work for me. I will need to get some memory for the thing. Cause you bet i will run some crap on it.
Well i will keep you all updated on how its going. Im busy with school and other things so progress will be slow
But in the end i would like to build a board that has Wifi+BT and SDcard slot. Possibly making it into a card size you know for that sweet handing out of cards so you could so it would be a bussiness card. Yes i know about the guy who did this. But his card uses completely different SoC which is far slower.10
So I got this tempered glass from AliExpress on my OnePlus 6, and I gotta say... It's a piece of shit.
The glass itself has that weird black bezel and because of that, it steals some of my screen on left, right, top and bottom. It's mildly frustrating. Plus the glass itself doesn't feel smooth, but rather a bit harsh.13
NEVER BUY ANYTHING THAT COST MORE THEN $5 FROM ALIEXPRESS....
I CANCELLED AN ORDER LIKE 1HR AFTER I PLACED IT, 3 DAYS AGO... I JUST GOT NOTIFIED THE ORDER IS NOW SHIPPED....
ALSO SEEMS MOST THINGS ON THERE A CHINESE RIPOFFS... BEING MARKETED AS QUALITY GOODS....
Oh and their customer support is really sketchy... they said they'll try to get me a refund... But as I was taking to her, I also placed a dispute on my credit card "just in case"6
So I plan to ditch my 17" heavy gaming laptop to chose something more suitable for school for a (13/14") ultrabook (I plan to run Debian on it) that has a decent battery life
Anyway, I looked at those chinese ultrabook on AliExpress/gearbest but I'm a bit skeptical about some factors.
Anyone has recommendations about a model or some advices?9
What is the difference between battery and rated capacity. I tried googling and theres a very technically paper with the definitions...
But what does it mean in terms of using it to charge my phone.

Hey guys, what are your favorite truly wireless headphones?
- my OSes: Android (phone), MacOS (laptop), iOS (tablet).
- my getting in love with wireless audio story: I have been using some Chinese ones off AliExpress just to test out the truly wireless waters, their sound quality and pairing experience especially on Android is pretty shit but the ability to forget that you have headphones in your ears and just listen to music obstruction-free is 🔥 but they are now dying so I am looking for a replacement.5
