I've been trying to get a voltage reading off the touchstone receiver coils with a multimeter. I have two sets of receivers and transmitters now (I thought the first one was defective) but both still read 0.0V. Does the receiver do some sort of load detection or have you guys been able to read 5V off the receiver contacts?
this was a problem for me as well at first. but the way I are it is this: I will be more likely to charge my phone throughout the day. ill keep a touchstone at work and one at home by the bed and one by my desk at home. the small trickle through out the day will help keep me topped off so I don't need those long large charges.
I did the whole mod for about 35 bucks but I already had the tools. The only thing you need is the touchstone starter kit (back and base) and some copper tape. I got the copper tape from hobby loby for 15 bucks. The starter kit is 10 bucks on amazon. If you want to get the higher power magnets (I highly recomend this, infact I got even stronger ones than the OP sudgested from the same site) than that will add on another 10 bucks (shipping is a ). So 35 bucks. Very reasonable.
I have a 3 hour drive to houston today. Ill test the compas and ill buy Jack and the Box too and test NFC. Will report back later.
Got my parts finally assembled. And the end result might be a deal breaker for me. Let me say that I absolutely love the idea of a magnetic plugless charging setup - especially in the car. But after all was set up and plugged in - I'm only getting charging at USB levels. This is while plugged into the wall - which when the same mini USB is plugged directly in the phone gives AC charging levels.
My biggest frustration is that I have had trouble squeezing it all into the extended battery cover and still fitting the cover over the extended battery... I'm going to try again.
