Here's a cool challenge.
Design an oscillator, capable of any waveform and any frequency that operates on supply voltages below 1V (it is allowed to have a higher voltage to start up but it must continue oscillating at the target voltage), using commodity parts, which include:
Here's my submission, it operates down to ~362mV but requires ~395mV to start up:
The next person should have an oscillator working below 362mV or so.

- resistors
- capacitors
- inductors
- diodes incl. LEDs
- transistors
- logic gates
- op-amps
- 555 timers (including low voltage variants)
