Screen shots from a PCB that I’m designing — an analog electronic bird song generator with a primitive interface for adjusting the song, aka “patch bird.”
Three studies of warblers for a new singing circuit (work in progress). The Red warbler lives in Mexico’s highlands, although its territory may become more northern as a consequence of climate change. The Cerulean warbler is considered to be at high risk of extinction due to human destruction of habitat. The Yellow warbler lives in North America and is thankfully not at risk for the moment.
This analog electronic birdsong generator circuit is comprised of 5 transistor oscillators, several passive filters, and an audio transformer “voice” generator.
Birds and the circuits that surround us.
