I found this little rotary encoder. At first i didn't know what that is, it looks like a potentiometer, but pins are weird. The pins are: GND, VCC, MS, DT, CLK It turns out it's a mechanical rotary encoder. What's rotary encoder used for?

Considering how this is my second post on the topic, and the first one didn't go well. I will try to redeem myself by performing a small exploration into how much it costs to make a mechanical keyboard from zero. Now there are some limitations to this. Of

Once i started assembling my own project usually i just went with LCSC electronics, or Mouser electronics. Those two options are the ones everyone talks about and i just took their word. But what if i dig a little deeper. This post will be purely exploratory thinking, because only places

I can remember a long time a go while browsing for videos on YouTube, there were a lot of tutorials on how to assemble mechanical keyboard. I said assemble because I'm pretty sure they didn't use PCB to wire everything. Instead, they built a frame that

Right away i will skip the internals of the DRV8825 chip, and just show the simplest way to set up and run the stepper motor with the driver. However, if someone finds internals of the DRV8825 interesting i found this website that describes it nicely: Pololu - DRV8825 Stepper Motor
Project
First goal with AS5700 was to track the movement of a stepper motor, but as i dug in tutorial it seems that the IC is not meant for it. It works great for tracking the rotation of the motor shaft, but magnetic encoders are used in those rotating dials that

On my blog previously i posted a post labeled as an idea for a handheld gaming console just for playing Chess. The goal was to make a gaming console out of ESP32 S3 which is a microcontroller, so it’s not really suitable for gaming console, but microcontroller as itself

How to make a wireless keyboard? It turns out it's not that easy. The way big manufacturers make wireless keyboards with those little USB dongles is a closed source operation. For example if I want to make a wireless keyboard with USB dongle, that can be achieved, but

Currently, my ongoing projects are all using some kind of microcontroller, but they are all limited by compute power. For example, I'm currently making a handheld device that runs striped down chess engine, and you can play chess against a bot. That bot is limited by compute power

Previously there was a post labeled with "idea" about a small device that can measure humidity, temperature and pressure, and it fits on keychain. The goal of this post is to show the process of making a PCB board for that device. Schematic was easy, considering how it
Project
I wish I had a small device that can fit on a keychain that displays temperature and humidity of the room. Winter is getting to an end and the problem of dry air will soon be over. But in times of warm weather there is problem of high humidity. So

Considering how dimensions of a Gameboy color D-Pad are nowhere to be found on the internet. A long time ago I bought one of those and never really played it. So I will measure those dimensions myself. There it is. Dimensions of a case are not there, because I did
