Old Calculator = New Magnet
Wednesday, December 31st, 2008A few weeks ago Dan and I went to an estate sale and found some great things, including a very old Commodore calculator. I already have a working Texas Instruments TI-1200 that I use in my office that is almost as old as me and fun to use at shows, but this cute little Commodore calculator was calling to me. It was missing a 9V battery, so I couldn’t tell if it worked, but I thought it would be worth the chance just to see if it did.
I bought it and immediately put a battery in it when we got home. I was really excited when the screen lit up and I punched in numbers. Not so much when I actually tried to do basic addition with it though – this calculator spit out nothing but incorrect sums at me. So away it went on a shelf, still cool to look at, but completely unfunctional.
I was about to throw it out a few days ago, complaining to Dan that I didn’t want to save a calculator that didn’t work, and I couldn’t think of anything to try to make out of it’s parts, when Dan had a brilliant idea (as he usually does) – make a magnet with it!
So I did. I separated the faceplate and keypad from the large backing of the calculator, and snipped some wiring away.
Then I superglued the keypad to the plate and wrapped it with a couple rubber bands to hold it all in place while it dried.
Using the superglue again I put some heavy duty magnets on the circuit board on the back and let it dry overnight. The next morning my new (super cool) magnet was ready to be placed on my filing cabinet in all it’s glory! Thanks to Dan for always thinking of something crafty to make when I can’t!
