CrayonXA (My First 9XA)

Learning transistors, power supplies, 555 timers, Schmidt Triggers, AND gates, darlington transistors and optocouplers all in one shot. It still amazes me this ever worked :)

The circuit for this design originated from Max Miller's 9XA (drawn in crayon)

A funny video illustrating how I still had much to learn about building circuits :)

More progress on the 9XA. Learning how proper transistor biasing and loading is important for controlling amplitude modulation.
