This digital clock was based on my Sidereal Clock circuit but uses 5mm red LED's in place of the 7-segment LED's I used, with 3 such LED's per segment.
designed a PCB for the project, and used a quartz-crystal timebase without the sidereal modification, so his clock tells normal time. At the left of the board is the voltage regulator heatsink, below that the crystal timebase. The small grey cables at the top left are the reset and blanking modifications described above.
