H M S Clock v2 Finished

(Because EC infers VCC and GND the VCC to the 7 seg LED's is not needed ) HMS clock. Using a 5v supply and regulated by a 555 timer. The 5uf and 430ohm R&C set the speed. This clock does drift over time, but it's a challenging and fun project to do and uses the full board with lots of referred connections. at 9 hours the clock will reset to 0 and start again. This could be an STMP timecode reader if the 555 clock was replaced by a derived sync pulse
