  • dFlex Sensor

    Dexter Industries is coming out with another new sensor for the Lego NXT Mindstorms system.  This one will mimic the bending motions of your finger, or measure the bend of different joints.  Check out the video!  We wrote a quick program, tied the sensor to our fingers, and had an NXT Mindstorms Motor turning with the flick of our...

  • dSolar Leak

    This week, we wanted to give everyone a small hint about what’s coming soon from Dexter Industries.  We’ve been working for the past month on a solar power system for the Mindstorms NXT system.  That’s right, soon you’ll be able to power Lego Mindstorms robots with nothing but the sun. Some pictures and a video of what we’ve been...

  • Does Cable Length Make a Difference?

    Burning on the back of our minds one morning was just how our thermometers would perform with different lengths of sensor chord.  The new Lego thermometer is limited, we’re told, by its IIC chords.  But because our thermometer line is analog, the sensor should be able to reach much further.  To test this, we took three open thermometers with...

  • Natural Log Iterative Calculation

    While working on some temperature programs, we found we needed to use the natural logarithm function. The natural logarithm function provided by Labview is not supported in NXT.  So we went ahead and developed this algorithm.  It works if the operator is greater than 0 (x > 0). The algorithm approaches natural logarithm by performing an iterative calculation.  The...

  • Temperature Control For Brewing Beer

    Humans have been brewing beer for thousands of years.  Crucial to quality brewing is temperature control.  Two typical steps in the process are steeping grains and the boil.  Both steps require strict temperature control; getting it wrong can make a mess, and even more tragic, destroy the beer  Learn more about how to avoid tragedy . . .

  • Tired of Turning off the Lights? Saving Electricity with the dSwitch and the TweetaWatt

    Earlier we posted on how we used some free time over the holidays to make Adafruit’s Tweet-A-Watt project. We wanted to see if we could combine the device with the dSwitch and conserve some energy around the office. We wrote a quick program that “listens” for a human, and turns the lights off if no one is there. The...

  • The Clapper – Revisited

    Clap on. Clap off. Watching old TV shows, we remembered that old advertisement and a light bulb clapped on in our heads. With lots of time on our hands over the weekend, we put a simple clapper together to turn the lights on and off. Then we thought, it’d be pretty cool to have some dancing lights when we...
