"Fuse the ITG3200 with a mag to handle slow rotations. Will it compete with infinite budget 1960s military hardware? Certainly not, but it's still pretty fantastic for $12, compared to what we had 2 years ago."
"Fair enough and well said. I do think the move to ARM will have many advantages."
"Popularity alone doesn't make something good. Once you're past the learning curve, the ARM MCUs are far superior to AVR8."
"Nice work."
"^-- The dream job for an entire generation."
"The "grab debian deps" step fails with "E: Unable to locate package scicoslab-gtk" on Debian 6.0 amd64.
I'm trying to build it from src but seems their git server is down.."

"I like the Easy Glider Pro w/ HobbyKing electronics. Probably costs 2-3X more than a HawkSky but way better quality, higher lift capacity, etc."
"Great work, thanks for posting this John. To improve accuracy, we could store the high res data on a PC or cellphone and send relevant sections to the UAV as needed. Perhaps a MAVLink/QGC extension is in order."
Hi Everyone,I'm testing Madgwick's quaternion DCM C code with a Sparkfun 9DOF sensor stick. It's oscillating a lot due to the accel integral term (like 5-10 degrees peak-to-peak, lasting for minutes).I know the idea is to keep the P gain low, so…
""Eliminate" iff the weather is perfect and you're in a wide open space with no multipath. In reality, you'll still want to fuse this with traditional sensors."
"Nice, clean, simple design. Very elegant. And good riddance to the arduino overhead."
"Erez, Digikey has a link to the HMC5883 datasheet. No parts though. What's your source for the 43? It's out-of-stock at every distributor I checked."
"Looks great. However the HMC5843 is EOL'd. HMC5883 is its replacement. Slightly smaller with better specs. But unfortunately, I haven't found a source for that yet, either. It's really been a tough couple months for mag sensors."
