A USB-controlled Solder Reflow Oven

[Joel] of [Helion Microsystems] is at it again with his USB controlled solder reflow oven.  You may remember him from his crazy twitter-enabled Ewok model. Although these two projects are quite different, they both use the HU-320 USB breakout board that he’s in the process of getting funding for via [Pozible], or Australian Kickstarter for Yanks.

The reflow oven works using a thermocouple-enabled RS-232 voltmeter to output the temperature to the HU-320 board. [Joel] has been nice enough to provide us with the C# code to interface with many multimeters if you want to implement a similar project.  Temperature is controlled with a mechanical relay for what would appear to be a poor man’s PID controller.

Sadly, Fluke meters don’t seem to be listed, but your place of work probably wants their meter back anyway!  For another toaster reflow oven implementation, check out this [HAD] article.  Be sure to check out the video after the break for a video of the setup! (heat treat engineers may find the “recipe” format humorous).
