RE: HP-67 Charger Connector
Here is progress so far:
   

This is my first attempt using a LiPo battery and charger. Unfortunately the largest LiPo battery that I have found that will fit in the battery compartment is 1000 mAh. But the setup works very well. The photo also shows my first attempt at recreating the connector. It fits and operates the shorting mechanism properly. I just need to find the sockets so I can finalize the model.

The connector will eventually be built into the charger case so there will be no wires hanging out.

I even found some PLA that almost matches the HP-67 original color. Sample chip is to the right of the calculator.

Still a work in progress but moving in a positive direction.

Thanks for all your suggestions.
