My son Harlan and his friend love to play “agents” and he asked me if we coud build “a panel that has a bunch of switches that turn on some random lights”. We worked on it for about 3 weeks, and this is what we came up with. The panel boasts the following features:
It’s loaded with switches, LEDs, a backlit 555 flasher circuit, message record/playback, and a Larson Scanner.
