We’re starting from a blank new Flux project: no components, nets, schematic, PCB outline, or requirements have been added yet.

I can help turn your idea into a concrete hardware plan, but AI execution is currently unavailable because the account has no available ACUs. Once ACUs are available, the next step is to define the project goal, inputs/outputs, power source, size constraints, and any wireless/sensor/display needs before building the schematic.
