I made a Digital Circuit Tester that does what oscilloscopes cannot. It is both a Logic Analyzer and a Digital Signal Generator.

With a total of 64 Input or Output channels, it is built from a few integrated circuits and a mini Arduino board.

It offers great flexibility for:

- Verifying the operation of other circuits.
- Generating custom digital signals.
- Emulating circuits that are not yet implemented.
