Hi everyone, Just to put in my two cents, I've started experimenting with this as well and I have the paste from Prime Electronics. "Multicore RM10" that someone mentioned earlier.. I've been talking with Alexandre G about this stuff and we have just started designing a temperature controller to adapt a toaster oven to a completely controllable SMT oven :) It will have the ability to define temperature profiles on a PC and download them into the controller then select them and run them standalone. Probably have the ability to log temperature to the PC as well just 'cause we can :) LCD and a few buttons for the interface. Temperature sensing using a thermocouple probably.. The intention is to release it for all to use. I'll keep everyone informed as we progress over the next several weeks. The questions is: do we make the SMT oven controller all surface mount components :) Chicken and Egg, which came first :P Cheers, Ash. -- http://www.piclist.com hint: The PICList is archived three different ways.
