A redrawn circuit diagram of the thermal flashlight described here: http://www.publiclab.org/wiki/thermal-camera
If you follow their materials list under Build Your Own > parts list, you will be purchasing a mini-breadboard with no power rails which does not match up to their diagram. This diagram provides support for a breadboard with no power rails.
The 3 separate pieces connected only by wire (battery, breadboard, arduino) can be cumbersome to use as a flashlight. Our guide at the bottom of the page linked here provides instructions to build an external casing that holds everything together as a single unit with only the LED and thermometer exposed. The case still provides easy access to the circuitry if needed.

This is the best story ever of jumping into a Public Lab tool and making it better. This great video should be embedded in the research note above: http://thermalflashlight.weebly.com/our-story.html.
Really well done.
If you had to do three things to make your flashlight even better, what would you want to do?
