For questions about teaching physical computing, hands-on logic design (simulation or FPGA) and peripherals. If your question is about making a demo, or fixing some hardware, this might not be the most appropriate place to ask the question.
Hardware covers a wide range of the subjects that interact with Computer Science, but the majority of computer science education is focused on the software aspects, and how software interacts with the underlying hardware. Questions about real, tangible hardware problems might be better asked on electronics.stackexchange.com or superuser.com
