My build progress

I have been working on a wave multiplier, and made short demo video which includes the first prototype: [Demo of Wave-Multiply-O-Matic] The recording is a bit noisy when signal levels are low. I suspect the BSP could be the culprit here. I’m struggling a bit with the configuration of the OTAs in the design. They appear to be quite sensitive to a DC offset of the differential inputs.
