@ Pete Brown - Funny…I actually own the same Radio Shack wall wart that’s in that pic…1A adjustable voltage…so far very good for projects, as long as you don’t need too much current.

I own 2 of them; a fixed voltage for my midi keyboard and one for general use. Good for powering circuits :slight_smile:
