As most of you know, the booms/arms are T-Rex 600 tail booms. I've cut the booms to 33cm and connected them to a 4-way 1/2" PVC connector (from Lowes). Screw holes are drilled 7mm from the edge of PVC connector. The body, which will hold the Arduino Duemilanove and Aeroquad 1.7 shield (amongst other things), is a simple 7" x 3" project box from RadioShack. To connect everything, so far I've decided to use 6-32 threads with lock nut washers - each lock nut has a rubber washer after it to help… Continue
Hey everybody, I'm attaching the code written by me for the Zhichuan zcc210N 2-axis magnetometer compass module. It's cheap, supports I2C interface and spits out data pretty good, including Direction (N-NE-E-SE, ecc) and angle (0-360°). Tested on Arduino pro mini. Frrrrresh.
NOTE I wasn't able to clearly understand how calibration is made. However the compass works fine even without calibration; google "zcc210n datasheet" for further info.
Ciao to everybody, just want you to know that today I finally made my EM406, ArduIMU and Ardupilot work together with a simple trick. From http://seniord.ece.iastate.edu/dec0803/manuals/EM-406%20Product_Guide1.pdf we see that the output baud rate of the infamous EM406 is 4800 bps. Adjusting the code for arduIMU, ardupilot to work at 4800 everything works very fast, ever without the "first time" GPS locking… Continue
"Quadrotors are getting smarter and more talented, but besides surveillance, their usefulness is a bit limited due to their size. Where one little helicopter fails, however, an assemblage of little helicopters might be able to…
I have been asked if I would mind supplying the SET file for my Stryker. See attached. Please keep in mind if you plan on using this with a differnet AP other then Atto then P and D gains may be way far off. Our scaling factors may not meet eye to eye. I also have added rudders for active yaw dampening.
SpaceX launched its brand new Falcon 9 rocket on Friday and the flight was a complete success! SpaceFlightNow has a great rundown of the whole sequence of events and some awesome pictures to go along with it (including the one above).
So found out the reason for the sudden flip during NAPA flight #1. Noticed on NAPA flight #4 the grip tape was slipping & managed to save her to see the grip tape completely loose on the ground. Unfortunately an attempt to reinforce it with duct tape failed & she crashed hard on NAPA flight #5 with the propellers having slipped forward & with the pilot assuming they were slipped aft, ramming Her into… Continue
