Yes that is the temp sensor. In fact there are two. They are 0.5mm k type thermocouples. As you can see I made use of the rotisserie fork. I cut it up and drilled holes in and pop riveted it to form a hinge. One sensor goes to the pid controller and the other to the data logger.
oh crap! I did it again :P stoopid iPad. Have a look on w w w . Photonlexicon . Com it is the best laser forum with heaps of helpful info and people. Search die4drive , die4drive pro and die4chill. Robin is user uk laser and I am kitatit. Hope this helps. Kit:)
Nice. What's cookin? Looks like some nice 5cm x 5cm PCBs from itead or seeed studios. I'm going to make a reflow oven controller soon, too. Thanks for posting this!
Use small diameter thermocouples. The 0.5mm ones respond much faster than the 1.5mm ones I first used. This PID controller gave good results but the time divisions are in minutes not seconds so it can be a bit difficult to create the ideal ramp times. Check out factorymation online, they sell PID controllers with rs485 interface. With the aid of and rs485 to USB adaptor you can program the cycle from your PC. Good luck. Peace. Kit :)
Sorry for the slow reply above. After trying a few times, I finally figured out it was because YouTube doesn't allow URLs in comments, so I had to delete the link to factorymation.
Also something worth noting is that most toaster ovens can get hot enough but they can't do it quick enough. This unit was originally 1500w at 240v. I replaced the elements with higher wattage ones. use as much wattage as you can. and go for elements with a smaller cross section.

Hi tarsius4,
Thanks for the props!
I'm cookin laser diode drivers with analog modulation desgined by Robin at w w w . die4laser . c o m
They are for my RGB laser light show projector I'm building.
Good luck with your project and have fun!
Kit:D

Great video. Getting ready to construct a reflow also. Anything you would change looking back?
Thanks
