After my experiments with the thermophile sensors, I decided to give Sparkfun ‘s 5DOF a try. Thermophile sensors worked well, but you need 6 sensors to be able to make nice turns. Then it becomes annoying and a lot heavier than this 5DOF module. It’s not that much cheaper eather (10$ per thermophile sensor, 110$ for the 5DOF).
Anyhow, after some troubles with the creation of the test board, it is finally done:
I also needed a new programmer to program the dsPic I’m planning to use. Ebay pointed me to a chinese ICD2 clone. Not bad :-)
Now the electronics side of the tests is finished, I can move on to the software side (Kalman filter!) which is more my cup of tea.
