Merry Christmas wishes from Rodalco2007
A 12 bit discrete componented LED Christmas star was built with four 7490 and one 555 IC and some Caps and R's.
4096 pattern combinations are possible.
If you carefully watch you notice that one bit led string failed to illuminate. A poor solder joint was the cause which has been remedied by now.
