small single color LED Cube

This is a small LED Cube build from blue LEDs.

It was build with a couple of LEDs with 5mm diameter. They are all soldered together with Ø0,6mm copper wire. All the cathodes of the flats are soldered together.
The soldering was done with a 3d-printable baseplate which is also included in the project-files).

You can find the circuit diagram for the controller board as an image in the project files. If you want to use another case or run another program on the microcontroller, there is also
