RE: HP-19c almost works
In the meantime I can mention that I have given some thought regarding how to accomplish a versatile battery solution that enables “normal” charging of the calculator, as well as external charging in an easily handled manner. My solution is found in the pictures, a factory-mounted AA 2400 mAh NiMH battery-pack with a miniature connector, intended for RC cars. A corresponding connector is soldered to the power terminal of the calculator, and yes, the back cover can be fit and stays in place. The battery pack can be easily removed and charged externally with the USB charger that was delivered with the battery pack, the only extra item needed is the connector that is soldered to the power terminal of the calculator.
best regards Jonas |
