Nicely done mate...i'll buy you a ruler so you can get your LEDs in a straight line hehehehehe
The next project would be almost the opposite to what you made......a lamp-checker, with a matrix of P.Button switches to manually fire each lamp at leisure, which beats the hell out of using the pinball 'lamp-test' mode....
Along the same lines, a coil-checker could also be made to work the same as the lamp-checker....
Well done!
