I was kicking around the idea of making a low powered rechargable battery operated device which would recharge via mutual inductance. I have heard of this before but I have never attempted anything similar myself. Any thoughts on how it might work out what type of circuit? This is not so much a request for an answer as it is an open ended discussion. The device would probably be similar in power consumption to a PDA or a cellphone. And the battery would likely be 3.7 Li-ion.
