easy recharging method for child's toy Answered
I want to use a rechargeable battery inside a toy, and I don't want to remove the battery for charging. I'm looking for a simple and safe method for charging that a young child can do by themself. Here are some thoughts I've had:
wireless (such as with a qi pad) = Is there any way to actually keep this from getting hot? I'm assuming the base would be always on, and the toy would be left on it all night or longer.
solar = This requires a light or the sun to charge. I'm considering putting the solar cell in the bottom of the toy and making a light base that it could be placed on, but I'd need some type of sensor or switch so it only lights when the toy is on it.
metal contact pads = This would be easier than a plug since you'd only need to set the toy down, but can it be done safely?
Anybody have suggestions? Thanks.
