Post by: Hefty on January 11, 2025, 12:23:56 AM
Wondering what whould be the the right spec for the LDRs to use in the Vomet Comet pedal build. I recieved the pcd in a grab bag and would like to build it but In the Docs can find which ones to use. Any help

Pretty much anything should work.  In the build doc you posted, the designer said they used LDR's from Tayda, and all the ones there are around 10k-20k resistance in the light, and 500k to 1Meg in the dark.  Most of them have peak sensitivity around 650 nm (red), with one peaking around 560 nm (green).  You could select an LED color to match, although the build doc mentions using orange diffused LEDs which are halfway between @ 600 nm.

3mm orange are what Chris (board designer) recommended.
