Since Chris said that he'd love to see more stuff being done with netduino plusses... thought I'd share my N+2 build.
There's a fairly large imgur album already put together, so for brevity I'm just going to link that for a lot of the build itself.
Right now I'm in the last phase of development, which is just code. I'm working on the user interface for the LCD screen and getting that working, after which I'll start working on the web GUI for configuration and such. A lot of the code is written, it's just the glue logic to hold it all together, and most of the user interface, that needs to be completed.
It's a little outdated (I have a few updates yet to push from my laptop), but I keep the source code available on GIthub
There are a few people who deserve major props for this build. First up, obviously, are Chris and the rest of the Secret Labs gang who produced the Netduino Plus 2. Great little microcontroller. After that, Fredrik Rinsén deserves applause for his MVC-like web framework. I use an I2C bus library written by phantomtypist, which was derived from a version by Pavel Bansky. Lastly, I use Inquisitor's CPU load estimator to determine CPU load for the web interface.
