Hello! I recently just came about this old calculator/ruler in one of my desks and found out the calculator part of it wasn't functioning. (wasn't a big surprise) So I came up with the idea of replacing the old alkaline battery with a small slim rechargeable one and adding a micro-USB port to charge it. My question is would this project be possible or even cheap? I don't have any experience with wiring/soldering and don't even know the brand of the product. Any professional suggestion would be appreciated!
*Extra* Another idea I came up with was to add one of those solar panel type of things that are common among many calculators that would power the calculator and even charge the battery.
Here are some reference images to what the item looks like:
Dimensions:
-Width: 2 1/16 Inches
-Length: 10 Inches
Height: 2/8 Inches
*Update* The calculator requires a voltage of 1.5V as I researched the calculator's old battery.
