‘last of the super sine wave generators’
This instrument uses two microchips, both are a Intersil ICL8038. The controlled with a resistance duty cycle and can produce sin, square or triangle waves. For the purpose of this project I was just using sine waves. I purchased these microchips after doing research into making a wein bridge oscillator which was invented in 1891 by Max Wien, also the inventor of the “Löschfunkensender”.
At this point I am hoping to miniaturize the project and organize the functionality better – that and figure out how to play it. Here is a recording with added phaser:
