I like those $2 radioshack breadboards. SUPER easy to solder and finish up real nice looking

Yeah I agree for a circuit that is this simple I just use the prototype boards. I like the big one.

Make the circuit as small as you can and then cut it out with a ban saw. It's harder to solder but etching is time consuming and kinda expensive.

Also, why focus your laser? If your TEC is 15mm x 15mm (or whatever) just focus your laser to the size of your TEC. This will distribute heat more evenly over the TEC and decrease extreme temperature differentials on the hot side of the TEC. Your laser laser will not burn and this should lead to a more accurate and consistent TEC reading.
.
Just make sure that when you calibrate your laser & meter that you use the same focus setting on the calibrated meter as the DIY meter when setting the DIY meter's gain.

it wont matter.......that would mean unfocusing the laser gives out a different power :thinking: which it shouldnt
The amount you focus the laser should not affect anything.
