Source files and kit: Assembly Tutorial: In this video I explain how the circuit works, prototype it on a breadboard, fix the inevitable mistakes, design the schematic and PCB, and assemble the final product. For reference I did not invent this circuit it is a very classic way of making a die with 555 and CD4017 and there are numerous ways to make it. Mine is a blend/remix of multiple of them, I enjoy symmetry, PCB aesthetics and making sure other people can build it too, so this project is an attempt to do so. Credits, source & inspiration: - -
