Electronics Tech. My happy place is designing and building instrumentation. Also into bikes and geology.
Another example video of my DMM that automatically reports open vs closed leads in a voltmeter circuit.
Note that the meter reports continuity when in parallel with the transformer, but then the ~120vac when I flip it on.

I made a game called “Oscilloscope.” You use a joystick (smoothed by a cap) to try to match a DAC output. Rounds are one minute and it gets harder as you go.
Nothing fancy but still fun Hoping it will entertain my toddlers / stealth teach my stepson electronics.

Figured out how to dim my lights from the TV. Also toggle them on and off. Pretty stoked.
