[sdiy] Tunnel-diode like waveshaper (new student project video)

[Aaron Lanterman]

The student wanted to try making a waveshaper based on tunnel diodes, but these seem hard to come by in a useful form, so he used a combination of JFETs and diodes and op amps to emulate the tunnel diode curve:

There's a "wavefold" on the positive and negative sides, and the location of each one is separately adjustable with separate control voltages.

This was probably the most original project out of the bunch.
