Welcome to The Gadget Professor Show #291 hosted by Don Baine. A total change of pace this week! We are going to show you how to retrofit any battery operated device to operate off of a DC power supply. Of course the device will have to be stationary or in a fixed position – not a battery powered toy car, etc…
In this show we will adopt a battery ring light – the RotoLight. This device works really well but it eats up batteries, so I decided to modify it to run off of a DC power pack that I had laying around. This is a very hands on show!
We also feature our weekly tech news, comments, and interesting free software apps.
