Lenz Grimmer replied to Brian Boyle's discussion motor issues

Lenz Grimmer commented on Jordi Muñoz's blog post New 3-Axis MagnetoMeter Available (HMC5843)
"I recently got the magnetometer for my ArduIMU+ based Quadrocopter. Nice! I got it to work with the original ArduIMU code, but need to tweak my quad firmware some more to get it right.
But I was hesitant to solder it on top of the board directly, as…"

"The procedure to build and upload code to the ArduIMU is explained on the ArduIMU wiki. They also refer to this page on the ArduPilot Wiki. Make sure to choose the correct board type ("Arduino Duemilanove w/ATmega328"). The ArduIMU can be powered…"

"@Scotty: Actually, you can use the ArduIMU as a controller board (this is what I am currently working on myself): see http://code.google.com/p/easy-imu-pilot/ or http://diydrones.com/pr..."

Lenz Grimmer commented on Jean-Louis Naudin's blog post TrIMUpter: Full stabilisation and GPS position hold with an ArduIMU+ v2
"Very cool, thanks a lot for the detailed description. I am currently building an ArduIMU+ based quadrocopter myself, so I'll take a look at your work when I reach the software stage."

Lenz Grimmer commented on Christof Glückler's blog post Maiden flight of YAQ (sucessful)
"Very cool, I love the idea of using these Wago terminal blocks. Will use it for my own quadrocopter project as well, if you don't mind :)
