I love the detailed build log for a el-cheapo thermal imaging project.

One of the first things we heard when we started talking to firefighters about the potential for a heads-up display was “give us more and cheaper access to thermal imaging.” Being the tinkerers that we are, we thought we’d try to cobble something together with an Arduino and some off-the-shelf sensors. Luckily, some other folks in the Arduino community forged the way, so we didn’t have to start from scratch.
