Here's the first wireless charging The Other Half made at Tampere Hacklab. It has a custom 3D-printed case, Samsung S3 wireless receiver, and connectors made with copper tape and some thin wire. There were some issues in placing the wireless receiver. It did not work when placed in the center of the phone, possibly due to interference caused by battery. Placing it in the bottom half of the case solved the issue. This is the first prototype and improved versions will be made later.
