Misc Electronics

Small electronics side-projects that do not belong to a bigger project: a playground for spare boards and parts, and a little circuit for the car. The larger hardware work lives with its project, such as the ESP32 monitors in Power Dash and the radio in Space Station.

Why

A drawer of parts and boards is a standing invitation. These are the little projects that came out of it: each one small enough to finish, understand completely and then put away, and a good excuse to learn something new about how the pieces work.
