I’m really pleased how this one turned out. The PedalPCB Double Pendulum is a fantastic-sounding pedal with the added capability of left and right inputs and outputs for an interesting stereo tremolo. Individual volume for left and right, and speed and depth controls with a wide range of tremolo options. Three TL074s, separate LEDs for each side with two LDRs each. One flashing LED for speed (I used yellow) and one for bypass. Pretty straightforward build with basic components.
In terms of aesthetics, green enclosure is from the LMS mice witches (thanks for the Halloween treats!), knobs are Tayda 1510s. Cricut vinyl for the pendulum graphics (white for left, black for right) with knobs and control labels to match, as well as B&W color coded input/output labels.
Highly recommended! Don’t let a lack of a build doc hold you back. Using a forum search, grab a drill template and schematic to use as a BOM and heat up that iron!
