Hello,
As I'm working on a project in a lab this summer to bring electronics lessons into my classroom, I've become very interested in inductive charging and have been working with the Inductive Charging Set - 5V @ 500mA max. I was wondering if a circuit schematic is available to understand how the transmitter and receiver are put together. It's a very small circuit minus the two rings of coil so I think there can be some valuable lessons. Would this be possible to obtain?

Re: Inductive charging schematic
We don't manufacture these ourselves and don't have schematics for them. But there is a nice inductive charging tutorial with schematics here: https://sites.google.com/site/ddmcintos ... ve-charger

Re: Inductive charging schematic
Also, I wanted to note a very interesting observation. I was able to measure an inductive voltage on the receiving end (powered 3.7 V on the transmitter and measured about 4 V at 2cm apart) and a standard inverse function from there, but ONLY when I used two transmitters. In other words, I used a second transmitter to act as the receiver. When I tried it the standard way (a powered transmitter and measuring with the receiver), I found no Voltage. Any possible reason? That's a big reason for why I'm hoping to see a schematic as well. Hope someone out there can help.

Re: Inductive charging schematic
They are really designed for 9-12v input on the transmitter side. With less than that, the receiver output is zero to inconsistent.powered 3.7 V on the transmitter
