CircBench

The CircBench project notebook

Good circuits start
with understanding.

Make something you can explain. Follow an audio circuit from its schematic through simulation to the connections on your board.

Projects for your bench

Breadboard, perfboard and stripboard. One clear step at a time.

perfboard · beginner

Wire a two-input passive audio mixer on perfboard

Learn why a passive mixer loses signal, draw its summing network, simulate one driven input, and follow a checked perfboard build with screenshots.

perfboard · beginner

Build and simulate a passive treble-cut circuit

Draw an RC guitar treble cut, understand its loaded response, and reproduce a checked perfboard build with clear screenshots and project downloads.

stripboard · intermediate

Bias and build a two-transistor fuzz on stripboard

Trace fuzz bias, run modeled waveforms, and build a checked vero layout with three essential track cuts, exact wiring and step-by-step screenshots.
