@IRON HORSE posted:GRJ, This caught my attention. Is this what I think it is: a device to drop a 110 volt accessory down to a 5 volt dc accessory that you can then attach to a 5 volt power source? I have a 110 volt used accessory that I'd like to make this conversion:
Yep, that's exactly what it is. Obviously, you need to put it into a proper enclosure as it's running 110 volts on the primary of the transformer! It claims 600ma, but I suspect 200-300ma is closer to what I'd expect to be able to draw from it.
eBay: 373578134151 has them for $1.66 shipped free. I also notice they reduced the power output claims to 300ma, more along the lines I was thinking would be the capability of this board.
