Thermal Flashlight (http://publiclaboratory.org/tool/thermal-photography) built around ATMega328p on an Adafruit permaproto board (https://www.adafruit.com/products/571).
At its heart is an Arduino and a touchless thermometer which then illuminates the subject with a color based on the temperature.
I implemented the whole thing at 3.3V so that four AA batteries would run it for a good while.
Although the backlight and the lights are powered directly from Vbatt, but everything else is from a 3.3V regulator. And the processor is running on its internal 8MHz clock (valid for 3.3V operations).
It includes a nice snap-together case for the Adafruit board and an LCD and a similar battery-holder.
Printed in PLA on a Makerbot Replicator (original) should not require any support material. I even added a few break-away supports where it seemed wise. Make sure to print "face-down." Some of the STL files may need rotating.
The snap-together joints require much more force than you'd think. They seem ok with 20% infill. Although the "brain top" should probably be 100% given all the little stand-offs inside.
The "brain top" also likely needs tweaking for the exact dimensions of your LCD. So measure twice and print once. [Well... measure and print at a 2:1 ratio at least.]
This is very much a 1.0 release with a number of non-fatal flaws:
The sensor head needs a better back and a maybe a bit more coverage, plus should be printed in a opaque medium. The battery compartment could be smaller and needs something to keep the batteries from just falling out, but I was trying to minimize the number of new elements i had to design. The connectors are too rigid and the cable space is too small. The power-switch mount needs more tweaking, as is it doesn't quite snap right nor nold the switch without some glue.
