Just received our first prototype of a Nickel-metal Hydride battery charger with a USB plug. This board is made to charge from 1 to 6 cells in series and supports a thermister for sensing overheating batteries.

This circuit design is planned to be a part of a pen-like stylus with a camera and haptic feedback for blind people to feel visual art.
