Does anybody know what the geometry of the core is in a electric toothbrush charger? I have an electric toothbrush that charges when it is in the cradle.
I would like to use a similar design for charging handheld radios for our troops. There are problems with salt water getting into battery packs and corroding contacts and so on.
I am mulling over running a MHZ or better sinewaves through the interface. I was thinking probably a sheilded ferrite half cup on each side of the interface should do it. I was wondering what effect the gap would have .
