I recently saw a thermometer simulation, it used mercury. However, it was:
1) Too slow. I had to wait about 10 sec. before the mercury grows.
2) Too big. I'd like to implement a thermometer in my simulations, but the one I found was as big as the window.

So, I thought about making a fast, small thermometer without using mercury, deut or similar things (those which expand with heat). The alternative seems to be a semi-conductor: what do you think about this?

This is my idea: the termometer is an horizontal bar, with a strate of semiconductor and another of something (let's call it S) - maybe just air, diamond, etc... (those which conduct - fast - heat). Theorically, a higher temperature means more semiconductors activated, because the strate S doesn't fully conduct heat - the temp. on a side is the same on the other side - but it "cools" a bit.

All semiconductors are sparked every second. Activated semiconductors will conduct electricity, and the electricity will activate a LED or, later, a screen (1234...).

Is this idea possible to do in PT?
