CatSynth Video: 4093 Quad Oscillator

Video by Tim Kaiser of his cat with the 4093 Quad Oscillator and his cat.

The 4093 Quad Oscillator is a popular lo-fi DIY circuit based on the 4093 NAND gate. They look very simple to make, so we at CatSynth plan to make one ourselves at some point. Big Merp will love it 😸
