Supplying power to rotating or other object without wires or wipers

I found this on the MRH site and post the link.

If it works as well as shown will be a good solution to powering some devices.

I have a narrow gauge turntable under construction so this seems the way to
get power to the tracks. I ordered up a couple of the devices so will see how it progresses.

LOL, before I opened the link I thought (you mean like the recent wireless induction charges that are all the rage for smart devices?) and sure enough that is what we have here. This is cool, but a bit too bulky for what I use the slip rings for (which have worked reliably for around 20 years so far).

That circus is so darn cool!

Pete,   Do you have a pointer to that barrel organ recording of the Liberty Bell march that you used in the video?

Thanks George!  Roland's wonderful modeling inspired me to join the project and do all the lighting/animation. Since we;re getting way OT, I'll PM you.

I plan to recharge the batteries on a HOn30 combine
which will operate the interior lights, marker lights and a figure
with a lit lantern. Would avoid pickups and would charge up when
parked in siding.

The smallest inductive charging coil is only 10mm (0.40") dia.
so will fit in the combine just fine.

Good to know. What you are planning sounds like a perfect application for this circuit.
