This is my first non-nixie clock. Built using the schematic and code provided by José Pino .
José has provided pre-compiled HEX code suitable for the PIC16F628 (I'm using a PIC16F628A without any problems) Code is also supplied for the PIC16F84. The layout is very simple and keeps good time - gaining only a few seconds after a couple of weeks running. The first photo shows the complete clock (two surface mount capacitors are mounted under the board, as well as the two 10k pull-down resistors from pins 6 & 7).

I have just received my 'Core' laser by Wicked Lasers . Purchased though laserpointer.com for a very reasonable price, I am very impressed! It's very green and very cool!
