HP41c battery pack refurbished with micro USB connector.
Dear friends,
just a few words to share my last project I have been working on.

I have refurbished an HP41c battery pack with new batteries and what makes it more special is that it can be connected to any mobile phone charger or to a laptop through a micro USB connector implemented. As I have removed all the circuit stuff, there is room for the new batteries, keeping the originals (circuit opened) for aesthetic & structural purposes.

I share some pictures.

Hope it is useful for you.

Kind regards

Ignacio
