Cool picture of my NXT illuminated by the Dexter Industries’ upcoming 6-DOF IMU’s U-R-Blind LED™. The red light is the power strip’s main switch and the green in the foreground is the light on the HiTechnic Super Sniffer, an I2C protocol analyzer.

Dexter Industries are currently developing a great new sensor, a proper 6 Degree of Freedom (DOF) Inertial Measurement Unit (IMU) for the NXT. It consists of two sensors on a single board; a 3-D gyroscope and a 3-D accelerometer. Both sensors can measure their respective values on the X, Y and Z axes. The sensor, like many of the other ...
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 ...
Read More »Bring on the Heat: Thermal Imaging with the NXT
Having spent most of yesterday hacking and optimizing the firmware for the new Dexter Industries Thermal IR Sensor, I thought I would go ahead and make something fun with it today. I built a pan and tilt rig for the sensor with a great deal of gearing down to allow me to take a lot of measurements as the rig ...

Hey baby, you’re on fire! No really, you are, I can tell with my new Thermal Infrared Sensor from Dexter Industries. This sensor came in the mail today, it’s Dexter Industries’ latest sensor, the Thermal Infrared Sensor. I haven’t had a chance to play with it yet but I have some great ideas in mind. All will be revealed shortly! ...

The NXT webserver has been up for a few days now and it’s really cool to see so many people logging into it to make the motor move. When I created it, I had no idea that it was going to be used as much as it has been. I’ve had almost 1200 views on the UStream channel and blog ...

I am currently streaming a live feed of my NXT on UStream. You can easily control the motor on my NXT using URLs like: http://xammy.demon.nl:81/MOTA=0 – stop the motor http://xammy.demon.nl:81/MOTA=100 – run the motor at 100% clockwise http://xammy.demon.nl:81/MOTA=-50 – run the motor at 50% counter-clockwise. The power to the motor can range from –100 to 100, with 0 being “brake”. ...

Among the things sent to me by Dexter Industries was also the latest incarnation of the dGPS, a GPS sensor for the NXT. This latest one is equipped almost exclusively with surface mounted components, making it a lot less likely to knock off one of the capacitors and giving the sensor a very professional look. The mounting holes on either ...
Read More »WiFi? Because We Can!
The mailman brought some shiny new toys this morning, one of which included the all-new Dexter Industries WiFi sensor. I don’t have all the technical details for this one yet, but like the NXTBee, it uses the NXT’s RS485 port for high-speed communications. It has a clip to hold a 9V battery on the back, the red and black wire ...

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 NXTServo controller, you end up with a very nice way ...
