The TouchTone555 generates sound using an NE555 timer IC which is configured as an astable multivibrator. Each key forms part of a series resistor network, which controls the oscillator’s frequency ...

There seems to be nothing a 555 can’t do. We’ve seen it before ... Beats us. The circuit is a bistable, so essentially your finger pumps a signal into a flip-flop. This is old trick, but ...

Flickering LED tea lights are a friendly and safe alternative to having flaming little pots of wax situated around your home, but sometimes the flicker scheme leaves something to be desired.

Because they are produced using algorithms they aren’t technically ... The output was then applied to a multivibrator circuit that cleaned the pulses up. The circuit of the noise generator.
