DIY Wireless Power Transfer

at 5:52 pm. Filed under DIY Hacks, Educational, Electronic Hacks


Very often when you are building a project there are two discreet sections. How do we go about powering everything up? Just use some good old copper wires right? That’s a good solution when the sections are fixed together but what happens when one section is rotating, in this case we can use power slip ring connectors but that is not very elegant.

Alan Yates had this issue when he was building a rotating POV device. Getting power onto the rotating section without placing a heavy battery directly on the rotating section was a challenge. Alan has documented the steps that he took along the way for us to enjoy. To see more details be sure to check out Alan’s Wireless Power Experiments Page.

    How about DIY wireless power to supply a swarm of robots?

    I agree wireless power transfer is cool, but to go as far as saying that power slip rings are not elegant is wrong, they are a beautiful mix of electronic and mechanics working together for a common goal.
