Besides me, I got an old Ender 3 V2 that still works fine. For control of its z position it has a lead screw. For other two axis it uses belts as everyone else. But why can't all axis have lead screws? As I'm looking at
Just made this bad boy. It is a ball and beam balancing device that serves as a learning tool, or even an example tool for closed loop control system. Will release cad models on github, so others can print it for themselves.
Goal of the day is exploring the control systems and its main mechanics, but do it all with words. Words? Usually when trying to learn this particular subject there are a lot of equations thrown at me. Each of those is important, and maybe it's not possible to
I'm on a search to find the fastest way someone can write stuff down. Awhile ago I was 100% certain the device I was looking for is something like Kindle Scribe, or Remarkable. So I bought one of those. It's from a different manufacturer though, and
This idea was in my head for quite a while. It actually started from an idea to make a product that i can sell, or at least try to sell. The market does not need any more clocks, however i didn't see much of this kind of clocks.
Lately my YouTube algorithm decide i need to watch a lot of videos about Linus Torvalds, and how Linux was made. That was the start of this blog post. So thank you YouTube. To me, the open source software is so badass when compared to closed source. There is something
Smallest keyboard layout possible is called 40% keyboard. It has about 40 switches, and those are all letters and couple of necessary keys for writing, like space, enter, backspace... In order to make something like that keyboard, a microcontroller with HID capabilities is required. In my case i used STM32F103
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
