I’ve noticed that Google Ads sometimes serves up ads into my blog that I think are offensive (and bizarre). I’m trying to get rid of them by putting them in my “competitive ad filter” in Google Adsense. We’ll see how it goes. (grumble grumble) I also just started using Google Adsense section targeting. I now […]
What are you going to bring? I’m bringing a fleet of semi-autonomous spherical robots keyed off GPS, on-board sensors and a Kalman filter; using sound, light and motion they mimic.. and even create their own flocking behaviors. There are no spectators at Burning Man.

Dear Lazyweb, I’m working on an project where we will have 5-10 robots moving around a large field… 100-1,000 yards. Right now we’re planning on using a mix of differential GPS, accelerometers and and a kalman filter so the robots can determine their position to within 1 meter or less. This may or may not […]
If you tried to submit a comment on the site recently and my spam filter said there was a problem, then I didn’t see your message. I know that I wrote “blah blah… don’t sweat it…” but feh, I missed it. Sorry.
