Building things across software and hardware.

This is my engineering log:
- backend (Java/Kotlin), iOS, and general programming
- microcontrollers, Arduino, Raspberry Pi
- small DIY projects and experiments
- tools, setups, and things I’m learning

The army of beatles is ready. Waiting for a programmer device to come and rule them all!

I also received a beautiful box of different things. There are resistors, LEDs, breadboard and many many more. We’ll try it today 🤤

The breadboard is quite low on quality
I’ve tried to install the power supply on it but it doesn’t fit. Probably the metal holes are defected.
Based on my previous experience it should go easy in, but it should. I my case it pushed out the back side 😖

The boss is here, well it’s time to fire the keyboard and write the traffic light program
But first, we try to blink a led. Blinking LED is “hello world” in microcontroller world

Added more LEDs and implemented it to be a similar to traffic light 🚦
Red, then red and yellow, after that green. After green we light yellow and then red

It has a lot of wires connected but this is only because of programmer, it needs “+”, “-“ and 4 more wires to communicate with the controller 🤖

Making a model for the traffic light housing
This will be the tool to bring the housing to the life 😎
I’ve tried this already and should admit I’m not an artist at all 👨‍🎨

We’ve tried to build a piece of traffic light housing as well as some other things. Looks promising, but also needs to be ironed.

We have prepared drafts for the traffic light 🚦
Next we’ll use ironing to make them a bit more flat 🤞
I expected it to be more accurate, but let’s be happy with what we have ☺️

Well, the ironing doesn’t help much
But this is enough for the first DIY project! Right? Right?… 🙄
We’ve built a box and added more plastic. Now we’ll try another round of ironing 🚬
