Sensors

I made a port of the ROBOTC driver to NXC.  The function calls are pretty much identical. The zip file includes the driver and a test program. You can download it here: [LINK].  Enjoy!

Dexter Industries have released their GPS sensor; it’s now available on sale for $105 US. It’s the world’s first GPS sensor specifically made for the NXT. I’ve had one of these beauties for a while now and it’s a lot of fun to play with.  You can read all about it on this page here: [LINK], which includes downloads of ...

A new release of the Driver Suite has been uploaded to Source Forge. Changes: Added Dexter Industries GPS driver + test program Added Mindsensors Numeric Pad + test program Added new "driver" with statistical functions Changed HTGYROstartCal in HTGYRO-driver.h to do more sampling for calibration data HTRCXreadResp in HTRCX-driver.h now clears all of the response buffer Made all calls in ...

Look what the mail man brought in today. This little beauty here to your right is a prototype of the new upcoming Mindsensors Numeric Pad.  It’s a very nice capacitance proximity detection based keypad meaning it can tell when you’re touching it without the need for actual switches.  That does mean that if you like to wear gloves while working ...

The HiTechnic Angle Sensor was released a few weeks ago and I’ve been eagerly awaiting a production version of it.  The wait is over now and of course the first thing that came to my mind was “I wonder what it looks like on the inside.” Gus from HiTechnic did mention that it uses a magnetic sensor to detect the ...

This baby had been announced prematurely at the beginning of this year when Lego Education accidentally ran its mouth in their catalogue.  Now it’s finally available to the public, the HiTechnic Angle Sensor. This thing is so ridiculously low friction when you turn it that you wouldn’t even know it was there.  With it you can measure the following: Absolute ...

My next project with the omniwheel is to have it react to bumping into things that it encounters on its journey.  I want to use the HiTechnic Accelerometer to do it, the Mindsensors one is currently being used in another project. I’ve been racking my brain for about 2 days now, analysing the data from the runs, trying to come ...

A new release of the Driver Suite has been uploaded to Source Forge. Changes: A driver for the new HiTechnic Magnetic Sensor has been added, together with an example program for normal use and for with the Sensor MUX. Added a driver to send and receive messages to and from an RCX using the IR Link.  You can also control ...

HiTechnic have released a new sensor, the Magnetic Sensor.  It can detect magnetic fields when oriented in the correct direction.  Depending on how the field passes through the sensor, the value it returns increases or decreases. You could use this to detect small magnets you have put in your obstacle course or maze to mark specific positions, like cross roads, ...

The GPS sensor is working like a charm.  Once it acquired the satellites outside on the balcony, it was able to keep the lock even when I moved the whole thing inside.  This picture was taken from inside my Lego Lair, about a meter from the window.  Not bad, eh?  I verified the position (blurred out) with my Android phone ...
