I think I posted a video a while back, where I used a green highlighter, a= =20 blue LED, and some magnet wire to demonstrate inductive power transfer. His= =20 solution is more straightforward, and less labor intensive. For the record, our engineers lack both facial hair and pony tails. I am th= e=20 only exception (beard/mustache), but then again, one could argue that I'm=20 not a "real" techie. :-)) ----- Original Message -----=20 From: "Charles Craft" To: "Microcontroller discussion list - Public."
