I posted some photos so my students could see the calculators I'm always bragging about. They have not been impressed so far.



He he, sounds as I have had your students too ;-D


What's that green buttoned calculator? Is it lab-tubes on the top? And don't worry - I can see it's not's not a HP ;-)

What's that green buttoned calculator?

That's one of those "water powerered calculators" that are not really powered by water: http://www.geeky-gadgets.com/water-powered-calculator-01-06-2010/

It is one of the "water powered" calculators. It's the only one that the kids seen to think is cool. I think so too. :-) Filling the little tubes with water and seeing the calculator work is just plain fun.


Okay, cool 8-)

If you want to you can join my FB group for collectors of old handheld computers and calculators. The group needs a little action...

Cheers from Johnny
