I had a few of the SCD55104A LED displays and I thought they deserved a nice project. They look super cool and retro-futuristic. So I designed a simple chess clock that used the display.
I had the PCB made at dirtyPCBs.com. They arrived quick, were super affordable, and came out perfect.
The project files are all on github. The only thing you need is 1 SCD55104A, an Attiny84 microprocessor and a few components.
I had the enclosure laser-cut at Pololu.com. Dealing with them was a breeze and the parts came back perfect to my drawings.
