Sensor #1: The Single Use Short Circuit Detect-OH GOD MY BOARD IS ON FIRE!

For my first sensor I wanted to create a device which would be able to detect a single short circuit.

But seriously folks. I wanted to try designing a board from complete scratch. This was a poor short term decision, but I learned a LOT. For instance:

I actually got it to the point that I could program the thing, but once I pulled up 3 traces and sparks / smoke started flying I decided to put frankenboard aside and redesign the whole thing with lessons learned applied.

Sensor #2: Light, heat, and proximity

My second board design was much more effective. PLUS it worked the first time!

It has a light sensor and a (previously on fire so not sure how well it works) thermistor. I also had an extra SHARP proximity sensor lying around so I figured I would throw that on there as well.

My application isn't everything I hoped it would be, since my original board ended up being more of a time sink than I had hoped. This application has 6 images of the boston skyline. The dimensions are heat and light. There is a cold and warm version for "afternoon" "dusk" and "night." The image that appears corresponds to what the sensor detects.

I plan to set this thing up at my apartment so that I can keep tabs on various environmental factors.
