Requirement #1:
* Throw away the Arduino.
I am going to add to the FAQ:
"Do not use Arduino for real projects. It is like building an automobile out of Legos and then expecting to actually drive it."
Also, fyi to Nathan. LM339 is a comparator not an opamp so it is not a good signal buffer. Use an opamp. See my article in Biocoder #6.

So, I've slightly redesigned the Arduino PCR thermal cycler (http://www.instructables.com/id/Arduino-PCR-thermal-cycler- ) to make it a bit better, by replacing the two wiremound resistors (100watts) with a cartridge heater (300watts) (http://www.ebay.com.au/itm/for-under-85/?ALLSTEPS Cartridge-Heater-3-8-Diameter- ).3-2-Length-220VAC-300W-/ 380898256650?pt=AU_B_I_ Electrical_Test_Equipment& hash=item58af4e270a
But the thing is: I have ZERO experience with electronics, and I don't know whether the cartridge heater will require too much power from the Arduino board or power supply, and all the explanations I've found on the internet seem to go WAY over my head.
Does anybody know whether the cartridge heater will work?
Any help would be greatly appreciated.
