The project where I realized I wanted to go from chemist to pro dev.

I built a flow-chemistry spectrometer with monitoring backend in Haskell.

Spectroscopy is where you add a reagent to a glass tube, it changes color, and by measuring the exact color it tells you how much of something (for example, a toxin) is present in the sample.

I had to do that a lot on factory samples, writing down measurements using pen & paper.

I'm lazy so I decided to do the logical thing: Automate it. I bought a second hand spectrometer, stripped the casing, did a shitload of glassblowing and hooked up tubes to the production pipelines, so I could get samples, mixing them in the correct ratio with reagents in continuous flows using valves.

I ended up using 2 home-crafted arduino-like boards (etching PCBs is fun!).

One to calibrate the mixture against known samples and control solenoid valves to continuously cycle through various reagents and deionized flushing water, the other to record the measurements and send them to a server running a Haskell/Yesod API.

The server collected the information into InfluxDB (A time series database), displaying all data on a graphite dashboard.

Eventually I wrote Haskell plugins for most of the chemistry processes, from pH & temperature measurements to polymer property and pigment tests (they made a lot of printer ink).

Then I was fired because they didn't need chemists anymore, and the code "could be maintained by the intern" (poor guy)...

But I did find out that I loved functional programming, chemistry automation projects, and crafting my own electronics during that time.

Any Home Assistant fans out there? Got myself a RPi3 a few months ago and got hooked on HA, because of the huge product support and great community. Didn't find any dashboards that I liked so created my own, written in JS, fully customisable and support for most if not all kinds of gadgets. The purpose was to have something easy to use for the whole family, on a wall-mounted tablet. What do you guys think?

Anyways, has anyone done some cool home automations/scripting? Would love to hear about it!

They announce the results and that was where the fucking plot twist was.

I was *not* on the list. I was devastated, to the point of depression. I refused to get over it, sulked at home, fell sick, skipped college for next two weeks straight. It took a few more days for me to recover.

After several visits from my friends and a lot of convincing, I decided to go back to college. I felt hopeless and had pretty much resigned to my fate. Being the idiot that I am, I missed several other interview opportunities during that interim when I was despairing-away.

Semester exams were about to start and I get a call from my staff saying I had cleared the coding exam for one of the companies that was coming for recruitment the next day. I had written this exam like several months ago and didn’t even remember having written it. It was such a short notice and I had zero time to prepare and my psyche didn’t want to(remember how I had resigned to my fate?).

I did manage to make it to the interview. I was expecting a tough interview (this company had a reputation for having tough interview rounds) but all I got was a bunch of tree and linked list and search algorithm related questions (internship interview). I had two rounds. It did really go well but I had learnt to not get my hopes up. Then I noticed other interviewees being called for a third round and they asked me to go home. I was like “meh”. I was used to it at that point in time.

Very unexpected to me, (but i’m pretty sure y’all have guessed at this point) I get a call saying, they have recruited me as an intern! 6 months later, I was working as an employee!

When I look back today, I realize that my current job, in every way, is waay better than the one I had so desperately wanted! The pay, the timing, the location, my actual job description, all of it! As a bonus I have an awesome manager who trusts me! I work with remotely with a team with such high standards and I learn something new everyday.

In my two years here, I have built a couple automation systems from scratch, I have mentored an intern and got him a full time offer, I have had two free two-week trips to the US and I have been promoted once! I’m so glad I was rejected that day (:

Thank you for reading!

Best part about home automation?

Morning coffee right in the face when your automation system breaks and goes nut.

My devGoals for 2019 are:

- Move DNS blocking from hosts file to a PiHole (or similar) at home

- Implement a full HAL for some smol microcontroller in C

- Create better automation templates for testing, building & deployment for our Angular projects

- Get rid of crippling depression

- Force my boss away from firebase and google tools in general

- Spread the love for CraftCMS

- Spread more love in general (with protection of course) 😄

A free, open source, modular (plugin based) home automation control center.
Ultimate goal is to support the core / apis and other devs code the drivers for the 'IoT' devices.
Also integratable with all the speech assistants like Amazon Echo, Google Assistant, Cortana etc.
Not that money dependent but very time consuming project.

Im starting in a week tho!

I wanna make you feel what you have brought into my house!!

I was working with security cameras once in a home automation project. One of those camera particularly stand out by offering a cgi without password request to view and change the current passwort and username.

Seriously wtf is wrong with you? I mean this thing automatically connects to an internet service offering everyone to connect to it with that passwort and username. And I know some of you might say "hey chill the cgi is only available on the wifi" - dammit no. Security is a lifestyle do it complete or get the fuck out. God knows what other mistakes there might be hidden in that thing screaming out to everyone to watch me taking a shit.

But that's not the end of it. My company arranged a call to the technical support of that camera so that I can explain the problem and a patch gets released. Those guys didn't give a shit about it and were even laughing at me. Fuck you!

So whoever is responsible - I will find you - and you will never see me coming.

Preparing homebridge on Raspberry pi.

aaah, memories. When I discovered github while doing my school project. Even my lecturer had no idea about, he thought I made it as part of my project 😂 Project was an Ionic app connected to Arduino for home automation. straight As I got... straight As.

Why did I invest in a home automation system? Cable Internet, that's why:

if (! public_internet_available) {
cableModem.turn_off();
cableModem.turn_on();
}

I recently tried to apply the same data analytics rationale that I use at work to my personal life. This is not a rant, it is more like an data storytelling of an actual use case I would like some input on.

I set a goal - gotta thin up a bit and calm down my ticker - and got a (almost unreasonably expensive) field expert consultant to yell at me about it for a couple hours.

I unravel the metrics - there is like a million weight-related KPIs and most say nothing at all. I have never seen an non-infrastructure measurable subject that could not be resumed to 2-5 performance metrics. I got overall weight, how well my nine-years-old business suit fits me, heart rate, and day-after relative muscle pain (it will make sense soon).

Then its data-pipeline time. I bought a cheap weight scale and smartwatch, and every morning I input the data in an app. Yes, I try to put on the suit every morning. It still does not fit.

After establishing a baseline, I tried to fit different approaches. Doing equipment-free exercises, going to the gym, dieting. None was actually feasible in the long run, but trying different approaches does highlight the impacts and the handling profile of each method.

Looking at the now-gathered data, one thing was obvious - can't do dieting because it is not doable to have a shopping list and meals for me and another for the family.
Gym is also off the table - too much overhead. I spend more time on the trip there and back than actually there.
And home exercise equipment is either super crappy or very expensive. But it is also the most reasonable approach.

So it is solutions time. I got a nice exercise bycicle (not a peloton), an yoga mat (the wife already had that one) and an exercise program that uses only those two resources. Not as efficient without dieting, not as measurable and broad as the gym, but it fits my workflow. Deploy to production!

A few months pass and the dataset grows. The signal is subtle but has support - it works! The handling, however, needs improvement, since I cannot often enough get with the exercise program. Some mornings are just after some hard days.

I start thinking about what else I can improve in the program, but it is already pretty lean and full of compromises.
So I pull an engineer and start thinking about the support systems and draft profile. What else could be draining my willpower and morning time?

Chores. Getting the kids ready for school, firing up the moka pot, setting the off-brand roomba, folding the overnight-dried clothes, cooking breakfast, doing the dishes, cleaning the toilets. All part of my morning routine. It might benefit from some automation.

Last month I got that machine our elders call "wasteful" and "useless crap lazy entitled Americans invented because they feel oh-so-insulted for simply doing something by hand like everyone always did" - a "dish-washer".
Heh, I remember how hard was to convince my mother-in-law that an remote-controled electric garage door would not make she look like an spoiled brat.
Still to early to call, but I think that the dishwasher just saved me about 25 mins every morning. It might be enough to save willpower for me to do more exercise.

This is all so reflective of all data analytics cases really are out in the wild - the analytics phase seems so small compared to the gathering and practical problem-solving all around. And yet d.a. is what tells you that you are doing the wrong thing all along. Or on what you should work next.

Best: learned to code, started writing smart-home scripts for home automation and developed biologic and quantitative data analysis scripts in Python and R.
Worst: didn't get paid to develop them and haven't got enough experience for it to be more than a hobby.

Well it's a bit long but worth reading, two crazy stories in one rant:

So there are 2 things to consider as being my first job. If entrepreneurship counts, when I was 16 my developer friend and I created a small local music magazine website. We had 2 editors and 12 writers, all music enthusiasts of more or less our age. We used a CMS to let them add the content. We used a non-profit organization mentorship and got us a mentor which already had his exit, and was close to his next one. The guy was purely a genius, he taught us all about business plans, advertising, SEO, no-pay model for the young journalists (we promised to give formal journalist certificates and salary when the site grows up)
We hired a designer, we hired a flash expert to make some advertising campaigns and started filling the site with content.

Due to our programming enthusiasm we added to the raw CMS some really cool automation: We scanned our country's radio charts each week using a cron job and the charts' RSS, made a bot to search the songs on youtube and posted the first search result as an embedded video using some reg-exps. This was one of the most fun coding times I've had. Doing these crazy stuff with none to little prior knowledge really proved me I can do anything with the power of will.

Then my partner travelled to work in an internship in the Netherlands and I was too lazy to continue it on my own and it closed, not so surprisingly for a 16 years old slacker boy.

Then the mentor offered my real first job. He had a huge forum (14GB of historical SQL) but it was dying, the CMS version was very old and he wanted me to upgrade it to the latest. It didn't seem hard at first, because there were very clear instructions in the CMS website on how to do that. However, the automation upgrade scripts didn't work well because the forum owners added some raw code (not MVC plugins but bad undocumented code) and some columns to the SQL tables. I didn't give up and decided to migrate between the versions without the scripts. I opened a new CMS and started learning by heart all of the database columns so I can make a script to migrate between the versions. The first tests ran forever because processing 14GB of data on a single home computer is not a task meant to be done. I didn't give up. I made an old forum and compared the table structures and code with my mentor's. I think I didn't exhaustively finish this solution, the task was too big on my shoulders and eventually I gave up. I still owe thanks for that mentor for teaching me how to bare with seemingly (and practically) impossible tasks, for learning not to fear from being a leader and an entrepreneur and also for paying me in time even though I didn't deliver anything 😂

A while ago, i decided to finally learn a bit about the web stack (especially django) and create my first web page. The image shows what it currently looks like.

I am actually very happy with the result. It will be my personal little Home automation software, with progressive apps etc. It runs on the pi plattform and can currently switch an IO to a Relais, which in turn switches on a light.

The applications of this are really endless, which is quite cool and leads me to do more stuff at my home with it. So dear devRant: Does anybody know of some nice hackable light bulbs/spots for my home that i can use? Or other cool hackable hardware that could be applied?

An incomplete list of 2018 personal dev goals:

* do more web development (It's fun. In a crude way.)
* finish the smart lamp I started building in 2016 ...
* fix up more electronic devices while learning their inner workings
* learn Python and some other language
* get myself a blog again
* get that testautomation thing which is haunting me in my dreams already to production
* be more relaxed
* do some home automation while not cursing all that much

Do you use personal assistants for home automation? If yes, what's your setup?

I'm thinking about setting up a RPi/similar with Jasper and bundling it up with Home Assistant, however, I'm not sure about the audio hardware yet.

Guys I'm very bad at staying focused on one thing.

For a bit, I've been learning web development, and I've been working on a page for myself. Past few days I haven't really done anything because I'm trying to actually fucking graduate high school and as of right now I am NOT graduating.

But today I was taking my calculus final and I ended up talking to the teacher for a bit. He said he has an older tablet that he's trying to turn into a type of wall mounted home automation system. I believe he said something about using essentially a minimal Linux install to do it.

That really got me thinking, because I had a fairly similar idea a while ago (not exactly home automation, but just using an old tablet as a small Linux device), but never put in any actual effort to get it done. Now with winter break coming up for me, I really want to try and work on it some.

So before I start doing a fuckton of research on this, has anyone here ever done something similar to an Android device? I'm not talking about using that Linux Deploy app or a chroot. I'm talking about basically removing the Android environment, taking it down to a base Linux install. I just want to know if anyone can steer me in the right direction to save me some time

I think another intriguing job asides programming is engineering (*for some*). A week has past and I've been on the hike assisting my beloved brother on his contracted engineering job while I am less occupied. The job is based on 🗼Tower analysis and It's quite risky as you'd have to climb up to 56 meters high just to take readings of antennas, and fix some other stuffs. The only thing I find intriguing about this job is his love for it, funny enough he also thinks I love the job too and I guess I'm guilty for his thoughts (*Sorry bro, I love the job for you not me*).
With my little experience so far on my *new brotherly job* I noticed the most hectic task isn't going up and down the tower taking readings but at the end of all operations, he'll have to gather the values and snapshots he took while on the tower to prepare reports on msword & excel for the other buttwags at the office (or home I guess)
then archive and sends via mail. Seeing this lengthy process I was forced to ask why he wasn't using any reporting tool like Jotforms or any other equivalent and I was willing to look up some recommendations for him, his reply was: "I'm already used to this form of reporting, its what I was trained with and what the company provided, nevertheless a friend of mine suggested something of such weeks back but I would have to pay monthly fee for its usage which is quite on the high side and I don't think I'd prefer that."
Sounds convincing but not enough, okay here is another deal: You use an android phone right? and at my office we work on system automation (*basically does not know what I do for a living probably thinks I'm a hacker the illegal one*), how about i design you an android app for you to capture the tower data and a PC software for you to auto generate the msword & excel reports, I can get this ready for you in less than 5 nights (*I've got less task on my desk, and was willing to take the timeout to prepare the solution that he needed, all I needed to hear for a kick start was an "Okay" just to be sure he wants it*) I suggested and re-assured but up to this point he still declined my offer and is willing to stick with his current reporting pattern (*Me died*).

I've been creating a new website layout for a small theatre group. I am like how it's coming together :)

It is designed with user interaction in mind because the layout they are using now is... Well, thrown together. It uses images as buttons and I had a few friends of mine ask "Where do I get tickets" and it is not updated regularly.

I plan to automate a few things like for shows, if the show date has passed, it will remove itself from the home page. I also plan to web scrape, if the site permits, some information to be displayed on the show page.

I got to lots to do before I can show them what I've made.

If anyone else is into home automation, SmartThings has a pretty awesome API

I want to build a home automation bot but I don't know what kind of features to give it. I have hue lights and I want a smart speaker/google home mini. Do you guys have ideas? I'm open for everything.

5 minutes till I go home. And server breaks... Out of space and a bunch of the automation tools have thus done harm. I'm no DevOps. But I just want to go home but have to sort it out.

Shortumation is a better way to develop and review your automations in home assistant without needing to install a third party automation engine like node-red.

It's been a while since i stopped programming.....
It's been so busy with all the school work/assignments/ and the most important part is that school ends at 10pm, arrive home at 11pm, prepare for tomorrow school stuff, sleep at 2am, wake up at 7am next morning, and again ends at 10pm 5 days a week...
It is exhausting, but I am getting used to this routine.
Studying my own programming skills or working on a side project? Not sure when to do it... The only way to continue studying is at breaks at school, or sleep less and study....
But it is impossible....
I have some great projects that are waiting to go out to the world, to list a few:
- cloud gaming
- cloud storage with live streaming
- complete school schedule management
- home automation framework in dotnet
- deepfakes and ai image generation algorithm (~18 months of training till now)
- game cheat engine (20GB total omfg ^^)
- and more
and I don't have time to finish it. lol
I think it will see the bright world after 3 years of high school... By then, my projects will be ancient, probably....

TIme is really short.
24 hours equally, but feels like 8 hours a day....

Should I abandon the project rn and focus on studying? (probably should)
or should i sell the project or open source it?

Also, how do you manage your time between work(study) and side projects (especially big ones)?

!rant
I'll move in with my girlfriend in August. So it's time to get a cleaning robot!
To either iRobot Roomba or Neato Botvac.

Which would you suggest and why? From the readings I've done so far, when it's about performance it's Roomba 980 >= Botvac Connected > Roomba 880, but then again the Roomba 980 is a lot more expensive.

Is there a dev, as lazy as I am with hands on expirience?

Note: there will be only a small carpet below the table in the living room and the appartment will have 4 rooms: living, sleeping, kitchen and bath. As the house is a little older, there's a "obstacle" the doors between the rooms to climb of about 1cm.

Thanks for suggestions in advance. On another note: I'm planing to get connected lightbulps and speakers, so we'll be able to control most of the stuf from our smartphones. So far I don't see any advantages, incorporating a vacuum bot in there, as long as you can set a scedule, any thoughts on that?

So I get to work on building a client at work for industrial automation. I am building a mini hmi to show customers how our server works. The code uses opcua. The reason I am making a client is because all the opcua hmis on the market are really expensive. There is nothing less than $600. There are hmis for free out there, but none of them say they support opcua. opcua has become a major protocol in the industrial automation industry.

It took me about 2 days to gin together a client that is pretty much abstracted and will be easy to maintain. A lot of that was just learning the opcua library client code.

Now I want to create servers and clients geared toward home automation for fun and profit. I want to take sensor data from arduinos using a simple serial protocol like modbus or other protocols that are supported. Then have an opcua server that collects this data. Then finally have an opcua hmi that I develop talk to these servers. The security model is much better and would be compatible with other vendors clients/servers. I already have a game engine I want to use for the hmi portion. It has tons of widgets for displaying data, graphs, lists, text, etc. It does both 2d and 3d.

This sounds like a project that could really fun, meshes with my work learning, and provides value to people that want to automate their lives.

The other side effect is that the next time I go looking for a simple and cheap hmi that supports opcua, there will be one.

I've dreamt of building my own home automation system ever since we moved into this place. By the time I'll get around to it, I guess the home automation system I want is common shelfware.

I've been thinking of completing my home automation side project.
But so far, all I've done is write code :(

So... I have 5 Raspberry Pi Zeros (no Wifi), one RPI Zero with wifi and one RPI 2 b+. I want to do home automation stuff with them. Any ideas?
I was thinking openhab, my only problem is that the rpi zeros dont have wireless connections.

Home automation
Lights turning on at the same time the wake up alarm goes off, blinds up and such
Centralized and shared calendar in the living room
And stuff that could bring me to jail (I've never done that and I'll never do it, I swear)
Maybe

Doing some home automation on the cheap w/ a pi and Ikea tradfri, just one more week of painting and putting in floors in my new place and I can start writing this bad boy.

So I'm interested in building a Raspberry Pi stack at home to continue securing and adding my smart home capabilities, 👍

Have ideas for 2/3 but what else could I look to add?

1. Pi. Hole with cloudflared argo proxy for all DNS
2. Home Automation server
3. IPS / IDS like Bro or snort? Or firewall like pfsense?
4. Log server with Splunk agent from other pi's and router....
5. What else?

Ideas in the comments

TL;DR : How would you 'smart home' with privacy?

How would you go about a privacy focused home automation/smart home setup?

What I feel is not necessarily important

> some assistant that you can have conversations with.
> Not being in home network to automate.

What I feel is essential. (in decreasing order of importance)

> Being a able to control appliances/electronics with voice/app (optional gesture)
> Have features to automate stuff, like turn on something if something happens (IFTTTish)
> Easily play music from Spotify or something similar, e.g. " * Play some Tchaikovsky."
> Simple alarm and reminder features.

So far I have seen relays and other devices that you add in the wiring and they connect to wifi. They work surprisingly well, but whatever I came across also collects personal user data.

Also not aware of any google home and alexa alternative that can so seamlessly pick up commands through ambient noise.

What are your thoughts and views?

P. S. I would have picked up something like this as my side project, but I don't see my self having that much free time atleast for the next 4-5 months.

When I was 7, I got my hands on an Amstrad CPC-464. This was my first exposure to code, copying examples out of the handbook. Shortly after that my school got their first IT suite, with thirty machines running Windows 98. I remember lunchtimes spent playing ZipZaps, a game that shamelessly capitalised on the first Fast and Furious films. I learned how to create macros in Office, and after getting a machine at home with Windows 3.1 I also learned some basic DOS. When I was 12 we got our first XP machine, which I spent hours on with MSN messenger and mucking around with scripts. That machine eventually succumbed to my brother repeatedly powering it on/off, something I still kind of hold against my mother to this day.

After going into care, I bought an old XP laptop from a friend, a machine that I used extensively. I mined my first bitcoin on that machine, bitcoin that could have made me a rich man today if I had only taken backups seriously.

My next machine came with Vista, which was upgraded to 7 shortly afterwards. This is when I got a bit more seriously into code, contributing to a game written in C++ (Armagetron Advanced, if you're interested). I also learned a great deal about automation using this machine, and when I got my second desktop machine at 18 (which at the time was still extremely out of date), I built my first working web server with IIS. I've been through four desktops since then, one of which just about survived a house fire.

Now I run a company of my own, doing development work at a lower cost for social enterprises, and developing a SaaS platform that will eventually make me a living all on its own. This year I hope to finally stop having to worry about debt, income, where I'm getting my next meal from and when I can finally be self sufficient, almost seven years since the care system spit me out after conveniently forgetting to tell me I could have stayed there until after Uni.

I am proud, though, of coming so far with no college or university degree. I'm by no means an expert, but I'd call myself proficient enough in a couple of languages to be capable of making a career of it.

Looking for speech-to-text library python for a home automation project. SpeechRecognition doesn't really work out for me and Google won't give me any other good alternatives. Thanks!

Wireless mesh
home automation
FPGA

I'm wanting to basically make a program or collection or scripts to automate all the boring parts of my life (cause I'm a lazy shit basically)
Any idea on what would be the best language to do this. I'm thinking python tbh. The end goal is going to be bills being payed ( I will out money manually into a PayPal account or something for this) and shopping being ordered to my house. Like I said I'm thinking python but wondering if there is anything better. I'm gonna end up having a computer or something set up just for theses scripts as will then extend into home automation or whatever I think looks fun. As the best way to learn is to try and making something fun

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?

We create home automation S/W and have it installed in the workplace.

For some reason the lights in the Help Desk/Testing department didn't turn on this morning. At the time our lead engineer was there too.

Rather then try sort it out themselves, they called R&D and got us to check the issue out. Turns out the lighting had been tripped over the weekend when the maintenance department was doing some work.

As we were investigating the issue they were just talking about their weekend so could of easily investigated it themselves!
