This week we got back to our hacking spree: we made an Arduino and LEGO MINDSTORMS talk.  This weeks example gets the Arduino and the NXT

Andrew Milluzi just posted an in-depth article on using the NXTBee radios with Labview for LEGO MINDSTORMS (LVLM).  He gives some great background information on data Throughput, Latency, and Speed. Check out his blog post here: http://08milluz.wordpress.com/2013/02/20/throughput-latency-and-bus-speed/ You can also find some software on his website for using the NXTBee’s and LVLM.  While RS485 communications are not officially supported in...

A few months back, Andrew Milluzi released Laview VI's for the NXTBee. This week we tested the NXTBee with LVLM, the LabView for LEGO MINDSTORMS (LVLM). We also are posting a few examples of LEGO MINDSTORMS programming to show how to use the NXTBee and LVLM.

A great new lab from K12Lab.com: using the Thermal Infrared Sensor to Measure Heat From a Computer

LVLM: now for the dIMU!

LabVIEW for LEGO MINDSTORMS NXT virtual instruments for Dexter Industries: now available for download.

We set out to put the new Dexter Industries Thermometers  through trials.  How accurate is it?  How quickly does it respond to temperature changes?  What kind of resolution do we get with it?  Just how good is the thermometer? First, Brian Davis wrote a great blog entry about the Lego thermometers and a really nice analysis of their performance. ...

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...
