Night Time is the Right Time

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. Read More »

Coming soon: Dexter Industries 6-DOF IMU

featured-6dofsensor

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 ...

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 ... Read More »

Lookin’ Hot: Thermal Infrared Sensor

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! ... Read More »

I’d Rather Be Streaming Robots

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 ... Read More »

Want to Play with my NXT?

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”. ... Read More »

Evolution in Design

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 ...

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 ... Read More »

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