Hi all, I have an arduino connected to a garage door opener. It uses xbee and a relay to open the door. All works fine, but I have to make it work without batteries, and I can tap 30VAC from the transformator. Does anyone know of a simple rectifier I could use to make a stable supply for my arduino…

If you have an AC outlet nearby...

Perhaps the one that powers the garage door?
