TypK to RGB Led

this little circuit reads a Typ K Thermocouple and indicates the Temperature with an RGB LED.

simple and cheap Arduino Robot

Code and some detailed information after the break

The RC boat of a friend had some problems with the nitro engine, but without data its not easy to adjust it.

So a Arduino with some thermocouples got installed logging data onto a SD card.

Just imagine driving around and then pull out the SD card from your boat and analyze the data on a notebook

Thermography was never so easy/cheap

after playing a bit with a webcam on a tripod:

I wanted to move the cam slowly over like 180° to get a nice pan effekt.

For the first try the webcam was attached to a stepper motor in half step, but with 0.9° steps it looks like crap.

so a small gearbox went between the stepper and the webcam, with a ratio off 1:1000, so the steps are now 0.018° as i move in fullstep.

Here is the final video with nice motion:
