A DIY solution

A PCB for a DIY oscilloscope solution, which just needs a handful of components, and the Scoppy Android app.

This PCB is based on the front-end design #5 for the Scoppy Android app. Credit for both Scoppy and the circuit design goes to FHDM.

Inputs for 2x channels use 3.5mm mono jacks, allowing for easy use with Eurorack and other patchable synthesisers. Great for calibrating oscillators and testing new modules!

Voltage ranges for each channel are set based on values used for R1, R2, RX, RF, and RG. Example voltage ranges can be found here.

Notes

– If RF is not required, use a 0Ω resistor or short using an old component leg;
– If RG is not to be used, leave without link;
– This circuit has not been designed by myself, and should be used with caution and at your own risk.
