Several techniques exist, but [Wolfgang] over at the Electronic Projects for Fun blog decided to go for the classic method of using a vacuum diode. He describes the design and analysis of a noise ...

If you’re the circuit bender or electro-noise-punk type ... s output to the input of the first oscillator through a diode and an approximately 1 KOhm resistor. (The resistor limits the output ...

Capacitors play three important roles in an electronic circuit: charging and discharging; maintaining the voltage at the same level; and removing noise. Diode The diode is a two-terminal electronic ...
