Solder Reflow Oven Build

I was watching the episode of Ben Heck's show here on element14 where he build a solder reflow oven out of a toaster oven and I thought this might make a nice project. If you'd like to check out Ben's build, you can check out the link below:

Episode 116: Ben's Home-Brew Solder Reflow Oven 2.0 Episode

I have started work on this project and will post additional details if I make any progress. To get going, I have chosen the MSP430G2955 to be the controller and will be interfacing it with the EA DOGS102-6 102x64 dot matrix display.

Here's a picture of what I have wired up so far. The MSP430G2955 is a 38 pin TSSOP package device and is attached to an adapter board for easier prototyping. I also used the Thermocouple Amplifier MAX31855 breakout board from adafruit, to let it do the math calculations for me. When connected to a Type-K thermocouple, it provides the temperature result to an accuracy of 0.25 degrees Celsius and sends the data out by SPI so that it can be read in by the microcontroller. I'll include more details in the future about the data format and the code I used to parse out the temperature result.
