DIY Water Powered Calculator
Instead of purchasing an eco-friendly water powered calculator and tossing out your old one, only for it to slowly rot in a landfill, you could make your own. It seems to be a whole lot more eco-friendly to convert your current items into something eco-friendly rather than replacing the gadgets you already own. Thanks to a tutorial, you could easily make your own earth friendly calculator.
The tools you’ll need include a calculator, carbon or copper rod, a 1 by 1 inch piece of aluminum foil, a small cylindrical container, two 3 inch wires, multipurpose pliers and a glue gun. The materials are pretty basic, nothing you couldn’t get from your local hardware store. I imagine this will work like any other calculator powered by water. You just need to make sure to refill the battery with water when it’s needed.
