anybody willing to make an instructable for this? (wireless power schematic) Answered

So, I absolutely love the "Wireless LED Throwie" project here:

videos:

But there's some conflicting info (10uf capacitor in the parts list but 1uf on the pcb template, and pcb doesn't match schematic or what's shown in the video), and some info is just never given (transmitter coil diameter and number of turns).

I want something like this where the transmitting coil is much larger than the receiving coils and can hold multiple, rather than the sizes being matched.  I'm hoping somebody a bit more advanced than I am would be willing to tackle this first and take notes.

AFAIK, the transmitting and receiving coils need to be close in size to work properly...

Did you watch the first video? And I've done it myself with a cell phone charger where I made a receiving coil less than half the size, and used it to light an LED. I just wasn't able to scale the transmitting coil up.
