When S/PDIF became available in the Teensy Audio Library I thought this might be the solution to ground loop problems I’d been having when interfacing projects to my PC. However, I quickly realized I didn’t have any sound cards with an S/PDIF interface. In the belief that I’d rather build than buy I decided to […]

A friend has approached me regarding his solar project. He wants to install a solar panel together with a battery and an inverter in order to have power at his allotment garden. He had looked at a hobbyist project where an arduino was used to build a MPPT (maximum point of power tracking) charge controller.

I just wanted a simle DCC central wich I can use to test new DCC locomotives n ad potentially with a “program” mode so it can “break in” new locomotives for me by running them for specific periods of time in both directions. The result is an Arduino based DCC central. It is based on
