parts for recharging batteries using induction ?

Question

My electric toothbrush recharges by induction, with no metal contacts = touching. I am guessing that the guts of this is basically just the 2 = halves of a transformer, with one half in the base and the other half in = the bottom of the toothbrush.

I've been thinking for a while now that this would be a great way for = consumer oriented robots to recharge. No contacts mean no sparks = (hopefully!)=20

Does anyone know of off-the-shelf components that be used to construct = something similar for 'bots ? I guess I could roll my own ( make that = "wind" my own! ) but I'm all for saving time & effort if they are = ready-made and affordable!

Thanks ! JCD

I'd start by buying another toothbrush and disassembling it :)

My dad bid on a job to construct the inventor of Furby's office. it included startrek type console, and nice electric reclining chair. The chair was battery powered and charged by induction.

I don't know of any ready made parts, but some wire and some circular/ cylindrical forms should do the trick. make it 120v input. step down to 14v, and then use rectifiers, caps, and voltage regulator to get your good DC supply.
