Another step closer to world domination

Posted on March 30, 2014 by Skye Sweeney

Fast update from last post. I got ChaN’s FAT32 working and can read and write files at 200kbytes/second. Not too shabby. With the FAT32 behind me, I set myself the goal of connecting my uBlox LEA-6H module to my ARM … Continue reading →

Posted on January 5, 2014 by Skye Sweeney

This weekend was bitter cold. With the temperature in the single positive digits (F) I was unwilling to drag my gear outside. But at the same time I needed to run some experiments. So I set myself up in the … Continue reading →

SUNDAR videos

Posted on January 3, 2014 by Skye Sweeney

I took the time to create a YouTube video on the SUNDAR. This gives an overview of the system: http://www.youtube.com/watch?v=DYgdluVEM1c And this is some more detail on the sensor head: http://youtu.be/ipH3iqc-TdQ I also found that I could get much better … Continue reading →

Adventures with an Atmel SAM7S256

Posted on December 29, 2013 by Skye Sweeney

The Arduino’s I have been playing with are nice and fun, but they do not have the horsepower that I would like for my AVC robot. At work I have been using ARM processors and really like them. They are … Continue reading →

SUNDAR getting close to field testing

Posted on December 17, 2013 by Skye Sweeney

I have a nearly complete prototype of the sensor at this point. The scanner will find and then track the sun as the car turns. If it losses the sun, it will open up its scan window to get it … Continue reading →
