Daily usability is a big concern when designing a device for a disabled population. I take a lot of things for granted, like being able to just plug my devices in when I need to or even hotswap batteries. The reality is, however, that these mundane tasks add a lot of overhead for the blind.

So I need to minimize maintenance of the device. 

Wireless charging is perhaps the easiest way to minimize user requirements, so I dropped a little micro-USB header on the board and am plugging it into a generic Qi reciever for cell phones. Will update soon with pictures, charging performance, and a schematic!
