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.

Just placed an order for a new prototype PCB (Printed Circuit Board) for makers. This one charges NiMH (Nickel-metal Hydride) rechargeable batteries with charging speed options, support for up to 6 cells, temperature sensor, and USB-C plug.

This is a step toward our first accessibility product for blind people to feel visual art through a haptic pen-like stylus interface.
