I did a major update to the CC2500 library today.
It's currently used to control an RGB LED light strip wirelessly, but should be easy enough to modify for other stuff. I hope the code is clear-ish and makes sense.
 
Code: https://github.com/alvarop/msp430-cc2500
 
Example of RGB LED use: http://blog.alvarop.com/2012/01/cc2500-project-part-6-reorganizing.html

That's awesome! I love reading about Toaster Oven Reflow projects. At my last internship I was surprised to find that a reflow oven was just an industrial/beefed up pizza oven of sorts. It's pretty cool that we can have that technology, though a bit cruder, in our homes.
 
I'd like to point out that you can reflow boards with components on both sides due to the surface tension of the molten solder. If you leave enough space on two sides of the board, you can sit the board on a couple rectangular blocks of aluminum, suspending the board and components above the metal grate. You'd be surprised at how strong the surface tension is.
 
I thought your video was great too! Did you use a stencil to get the paste onto your board?

Hey all,

Nate here, made a nice little reflow oven to help me in the construction of surface mount boards. Got a video explaining it all here:

Schematic:This is my old V1 schematic. Todo if you want a better board:
-Use a MSP430G2553 MCU (more pins and flash)
-Use a non EOL thermocouple driver IC: MAX31855KASA+
-Add in a FT230XS for a USB interface
-Add flyback protection to relay LSD if a mechanical relay is used.

Update: Schematic has most Part #s on it
 
Thermal-couple: (Important that it is low thermal mass and rated for temp range)

I'm not trying to thwart your plans, but I found a link to this webpage when looking up info on the g2553.
 
I can't post links since I'm too new, but if you google the part number "430boost-cc110l" the first hit is the webpage.
 
There isn't any info other than it listed as a preview device, but it looks like TI also thinks the launchpad needs a wireless booster pack. The CC110L is named their "value line" transceiver, so they seem like a good pair for each other. It could be months before they release it though!
 
I've learned a ton while following this thread. Finish the board so you can say you beat TI to the punch!
