I Recreated a Soviet Drawing Toy from the ’70s Using Python

Hi everyone!

I spent the last 2 months learning electronics, soldering, CAD, and MicroPython to build it completely from scratch. It uses a Raspberry Pi Pico, a TFT display, two rotary encoders, and a rechargeable battery.

What My Project Does

You can draw on the screen by turning two knobs(left one is X, right one is Y), just like the original toy. My version also has:

  • Color drawing
  • Saving/loading drawings
  • A rechargeable battery
  • A custom UI
  • A 3D-printed enclosure

Target Audience

This is mainly a hobby/learning project. I wanted to learn hardware and embedded programming while recreating something I find really amazing.

Also, if you want to try working with an RP2040/Pico or Arduino, or you've been into this stuff for a while, I really recommend checking out a video I made. I went through all the steps I took to make it. I'd love it if you checked it out!

Comparison

The original is completely mechanical, mine is electronical though and has the features I mentioned above;)

Video (explains it better than anything else): https://youtu.be/IhqKNODgfBE

I'd love to hear your feedback and what you think about it!

(I also made this commercial for fun, but I think video is way better though)
