I really like the work that is being done with these diodes and peltiers! You guys did a great job mounting these in place like that.

Oh, Well I never knew they were made of ceramic.
If they were flexible that would be AWESOME!

Thanks, for a while, I was contemplating cutting up my larger Peltier (92Watt - 40mm x 40mm) and creating some small ones (I may still do that ).

Chimo --

I may still try cutting one up - You have to study the connection paths.
Now the trick - How do you cut the two planes of ceramic ?? I don't know if a Dremmel tool with mini cut-off wheel will touch that stuff !! What's your plan ?

Mike

Off the top of my head, I was thinking a dremel with a diamond wheel. I also have some diamond impregnated files.

I thought about it first, when I saw a pic of a disassembled TEC. I was thinking about slicing down 2 or 4 rows. Perhaps even stacking two or three of them for fun.

My TEC Arrive in the mail today! It freezes water, and it boils it too... It also seems like it melted the solder on the top... cuz when I put water on it, it kinda changed the shape of the top of it... it still works great though. I wasn't even sending 5 Volts through it, I didn't check it's mAs though. I guess that means I need to solder up that driver circuit so I can put it all into a project box. well, that's all I've got for an update for now.

Glad you got it... You will only need less than 200ma's to keep your diode cool. Notice the sticky concerning condensation. The dew point calculator is useful. But as long as you keep it a bit cooler than room temperature, it will not condensate.
