This artwork is inspired by famous suprematist artist Kazimir Malevich (1879-1935) and his painting “Black Square”.

But I am not so radical. I have four LED squares inside one black square. Slowly blinking their different coloured lights.

I need to make another video when there is not so light and you can actually see the colours.


How i made my digital radio

This is my simple one-button radio. One button to turn it on and change the volume. There are actually two buttons more: first to select a new channel and second one to save it to memory.

It was a project that taught me how to draw PCBs, what are Gerber files and so on. I designed 4 different layouts, orders two. The first one had some noise problems. So I added some filters and ordered the second one.

It works and I am happy with it mostly. I do not have any education in electronics, so forgive me if it does not meet professional standards.

It is now my second stop motion animation. It took about a week to do. It could be better if I put more time into it.


It uses Arduino Nano as the main control unit.
