A DIY Covox Speech Thing clone designed for practice in PCB design and soldering. The project features adjustable low-pass filtering via switches, parallel port connectivity, and two board variants with flexible component values for audio output customization.
PCBSchemaGen is a benchmark and verification framework for evaluating LLM-generated PCB schematic designs. It provides 227 synthesis tasks and a deterministic 5-layer verifier that checks candidate SKiDL designs against electrical and topological constraints derived from IC datasheets, without requiring simulation or API calls.
