This is a Grind Customs Tourbillion Phaser. Thanks to Forrest for providing what I needed to have some boards made. I’m rather proud of the etch. I do have 4 more boards for 5.00 PPG if anyone is interested.
From the build doc: The Tourbillon is a three-‐stage optical phaser utilizing LDRs as the variable resistive element in each phase stage. The circuit grew from a single-‐stage vibrato circuit by Tim Escobedo (TheWobbletron) into a three-‐stage phaser. The LFO is closely based on the oscillator from the Causality 4 Phaser by frequencycentral.com .
