TI-30 durability testing (slightly off topic, BTW).
Message #1 Posted by Michael Meyer on 3 Aug 2010, 4:49 p.m.

I've ended up with WAY too many TI-30's that have been in boxes of old calculators that I have bought for the other models. (My definition of Way too many is more than 3...) I know they've been used for various interesting purposes, such as "packing material" for HP calculators. I would like to perform some "durability tests", and would like some input on this. I know they don't stand up to every-day use very well, but I still want to give them a chance. I'm thinking I might even get around to photographing these tests. My ideas so far: running over with car, bullet resistance, dissolvability in acetone, and surviving a fall from a tall building. Oh, and there's fire resistance and blending ability. Any other ideas?

Video this: Testing if it will survive lying on top of a jar of glass containing zinc powder and sulfur powder with a Bunzen burner heating the jar from below... until the jar cracks.

      
I'd like to make a suggestion

The problem with that washer is the brick(s) were in the wrong place.

I once had a front loader, and was it ever heavy. When I had to repair it, I found out why: It had large blocks of concrete bolted inside, just to add dead weight, so it would not vibrate so badly.
