Very instructive and helpful, thank you for this article. I'm still an amateur in constructions like this one, but will follow every step as described, thank you again!
Very nice write up, it is an enjoyable read and a really neat concept. However, I'm curious if this could be added to other devices... Is charging effected by the shape of the coil? Does the coil have to be in a perfect circle? what about position on the charging pad, does that have to be exact?
Hmm, what about several small coils? If I understand the concept correctly, several small circles should, in theory, transfer as much energy as a singular larger coil. My Thought is try and add something like this to a Bluetooth headset.
Thanks! glad you liked it!The coil does not have to be perfectly round, but that might affect its efficiency.In fact, in many other applications that use this technology (i.e. RFID, NFC etc.) the coil is rectangular. i guess you can shape it as you wish as long as it's looped around.You might want to do some experiments and see how this affects the energy transfer.regarding the position, it works within a small tolerance of movement. this is why these chargers have magnets to align the phone.I saw some commercial chargers that use 3 coils instead of one to allow for more flexibility in positioning the phone on the charger. maybe a bigger coil would help too, I'm not sure.

Oh ok cool, try for the clarification.
I run a Mini S3, threw in a Chinese system off Fleabay. In my car, I normally use satnav & bluetooth music to my radio. The wireless charging couldn't keep up with the drain, & the phone ran very hot, so I ditched it in favour of the magnetically held micro USB plugs & sockets. Those work well, up to an amp or more charging. Thanks for putting your 'ibble up, it works quite conveniently for just charging.
Is this like Wi-Tricity, or do you still have to have to place it on the charging pad, i.e. Cordless?
