How NOT to build an LED display

1 year ago

Looks like I missed a couple of key components on this design.
Not only did I forget the per element current limiting resistors but also whatever would stop the signals from being so noisy.

I know they are noisy because the second board has no chip and it self-clocks and eventually loads all 1's.

Any help would be greatly appreciated.
