small single color LED Cube

thingiverse

This is a compact LED Cube constructed using blue LEDs. It was built with a few 5mm-diameter LEDs, all soldered together with Ø0.6mm copper wire. The cathodes of the flat surfaces are soldered together. The soldering process utilized a 3D-printable baseplate that's also included in the project files. You can find the circuit diagram for the controller board as an image within the project files. If you want to use another case or run another program on the microcontroller, there's also a reset button in the circuit diagram, but you don't have to include it on your circuit board. The LED Cube is housed inside a Case that was lasercut from Ø3mm thick wood. All the wooden components were glued together. The side where the USB-Cable for Power supply is plugged in can be opened if you need access to the controller board. In my example Program, it doesn't matter which LED you connect to which output of the shift register because it displays a random view. What's crucial are the Pins reserved for the transistors. You can download the source and compiled program for my example programm on github.
