    NXShield for Arduino This shield is designed to fit on an Arduino. It will have 4 NXT motor ports, 4 NXT sensor ports and several RC servo motor ports. It allows you to use the I2C port on the Arduino. However it will have only a single I2C bus.  That […]

     
  • Improved Thermal Imaging

    Improved Thermal Imaging

    Experiments, NXT, ROBOTC, Sensors June 16, 2011 16:53 15 comments

    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 […]

These are the latest prototypes and they have undergone some great improvements; the rollers roll […]

     
  • Controlling your NXT with the Kinect

    After seeing the video posted on Mauro Brunato’s website, I got all sorts of ideas in my head for other cool things to do with it. With a little help from my friend SC, I managed to get my hands on one of these Kinect sensors as well. It wasn’t […]

    The Pneuma-Snatcher

    The Pneuma-Snatcher is a very ugly robot based on the very nice looking Snatcher, designed by Laurens Valk. I used the two valve kits that Mindsensors sent to me a week or so ago.  They work very well for controlling the pneumatic valves.  If you hook them up to the […]

    As promised,here’s an easy to follow HOWTO for making your own VEX Cortex to NXT converter cable for I2C sensors. Please keep in mind a few things: Do this at your own risk This won’t work with sensors that require 9V to operate This won’t work with analogue sensors Do […]

     
  • I2C on the VEX Cortex

    I2C on the VEX Cortex

    The VEX Cortex is a nice platform made by VEX Robotics. It is supported in two programming environments, one of which is ROBOTC. Much to my dismay, the master firmware does not support I2C, which is why ROBOTC does not support it. I don’t really like it when someone tells […]

    After spending two hours working on the changelog for the upcoming release of my driver suite, I thought I’d go play with something that was a bit more fun. I’m part of the ROBOTC for Arduino test group, which has been a lot of fun. The Arduino build does not […]
