I was working on an omniwheeled robot last night, trying some code that would ensure the vehicle would go straight even if the motors were not perfectly in sync. Unfortunately, there seemed to be a bit of a bug in the code which lead to some pretty erratic behaviour. So as you can see, not all of my projects are ...

After a prolonged hibernation period, the Mindsqualls project is back from the dead and version 2.0 has been released. I was using an older version in my super secret Kinect project, so it is nice to see that is being maintained again.

HiTechnic have released a new sensor: a barometric sensor that can also measure temperature! If you ever wanted to make your own weather station, then this is perfect for the job! It measures the pressure in 1/1000th of an inch of Mercury, which can easily be converted other units like Pascal and PSI. The temperature is measured in 1/10th degrees ...

Read More »Improved Thermal Imaging
After the initial post about my thermal imaging system using the Dexter Industries Thermal Infrared Sensor, I made some improvements with both the speed and accuracy of the whole thing. I made the sensor sampling interval time based, rather than encoder value based. This proved to be a lot better at getting consistent sampling rates. I also doubled the horizontal ...
