[DIYbio] Re: Electronic requirements for redesign of Arduino PCR thermal cycler

just found this thread. There is some VERY interesting ideas in this one that i need to go back and read in greater detail.

Hey, so I'm currently an undergraduate genetics student and I'd like to do some diy biohacking to really get lots of hands-on experience while I'm studying. At the moment I'm just setting up a basic lab by building some lab equipment based off plans on the internet.

So, I've slightly redesigned the Arduino PCR thermal cycler (http://www.instructables.com/id/Arduino-PCR-thermal-cycler-for-under-85/?ALLSTEPS) to make it a bit better, by replacing the two wiremound resistors (100watts) with a cartridge heater (300watts) (http://www.ebay.com.au/itm/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.
