The Trouble with Communications

Hey guys,

I'm still working on the next installment on my SAGAR drone, however my progress has slowed, as I suddenly find myself in Boston for 7 weeks. Life can be very exciting when you work for the Department of Defense.

In the mean time, I have been asked by a few people over at SocietyofRobots.com on how SAGAR's micro-controller (an Axon) communicates with LabView. Instead of a bland answer, I spent s little time writting about the different problems hobbyist can run… Continue

Video grabber for those that record their wireless video on a notebook

DealExtreme has a new video grabber on their website. The problem for the versions they already sold for some longer was that modern OS's were not always supported because drivers being unavailable.

Here is a link to Video Grabber…

Maker Fair NC

Make Magazine first annual East Coast Maker Faire? was held yesterday in Durham, NC. I made the 3 hour trip from Charlotte by amtrak and brought my daughter along for the experience. It was a good event - some 2000 attendees. The local Arduino club and Aerobatic Robot clubs were well represented, with a laser-cut quad in progress and several Arduino breadboard affairs. There were plenty of Sparkfun objects (LED button squares, pressure sensors etc...) A… Continue
