Goal of the day is understanding the PI regulator. Before anything there is a great resource that explains PI and other regulators in detail and its: controlsystemsacademy.com t = 0:0.01:10; % Time vector setpoint = 1.0; % Desired value Kp = 2.0; % Proportional gain(how strong the P part
I remember in college, there was one math professor that did the problem examples on the whiteboard, but when he got stuck he will real quick go to his laptop, open GNU Octave and type in a short formula that will solve him the whole problem. And then he would
Even though system control was main subject for me for a while in college, i did not grasp on that subject too well. The main outline is clear to me. We got closed loop and in place of the controller it's possible to put all kinds of controllers.

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

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
