Seems like this thermal flashlight thing is taking off as just when I've posted my gadget this thermal flashlight appeared on the Make Magazine Blog.
This guy, though found a nice LED flashlight pre-made which he crammed the arduino into. And while that is a nice package (especially the mirrored LED reflectors) it has no user interface.
While I was playing with the original flashlight I realized that the sensor it self is pretty capable, but that just showing colors didn't quite reveal that. The sensor has a 45 degree field of view, where it averages the temperature. So while it is very precise at measuring a temperature, you'd never know it by waving the flashlight around willy nilly, because 45 degrees might just as well be a wide-angle lens.
This makes light-painting pretty challenging because you sorta need to keep the flashlight very close to the surfaces you're painting or else you'll get some averaged color, not a temperature appropriate one.
And then there was the idea that the Arduino itself is pretty damned flexible/smart and that it is as much a platform as it is a flashlight. So this design has the LCD, a buzzer, and some buttons so that it can be more than just a light.
As it is currently programmed, I gave it an alarm and a programmable threshold. It automatically determines if you want the alarm to go off hotter or colder than the setting. However, the 45 degree FOV makes this functionality nearly useless for telling me when my tea is drinkable because you practically have to dip the sensor in the tea (or at least get it covered with condensation) to get an accurate reading.
I will investigate other versions of this part, there do seems to be several variants. Hopefully one has a better FOV.
I set it all up for 3.3V because I could and because I figured 4AA batteries would keep it going for a while. However, I did use Vbatt for the LEDs and the backlight of the LCD. I used the bare ATMega328p with its internal 8MHz clock again because I could, but also because that's valid for 3.3V operations.
I could probably get more battery life out by not using the lossy regulator, but that started to seem expensive.
This picture was taken on the RapidPro in Veldhoven. It shows the possibilities of additive manufacturing metal parts.

I printed this hand on my makerbot with a layer height of 0.25mm. Printed on a lexan platform instead of the standard acrylic. I think it turned out really nicely except for all the places where the ABS bruised from cutting off the strings. At this resolution, every little detail shows up. You can even see the knuckles on the back of the fingers pretty clearly. You can see how bad my Z wobble is here. I really need to get new rods...
And since this is made with a 0.25mm layer height and it is about 120mm tall, it has about 480 layers in it.
Oh and it looks better in person.

with some custom configurations - aka I broke some stuff and put together what was leftover and made this
