"OK, thanks Simon!  I read the readme on the tool and I see it will make a .jar of the parser.  That might be enough for me to just add the .jar as a library in android studio. "

For Those Who Like Simple

Posted on March 15, 2015 at 10:57am 12 Comments

I bought a 3DR radio from Whitespy to add telemetry to my MultiWii and it works like it should.  Multiwii has a processing program called multiwiiconf that is used to make changes to the PID's and for selecting flight modes and reading and writing to EEPROM.  There is also a slick GUI that adds a few more…

Flying my ArduIMU in tri_chord space

Posted on February 5, 2014 at 6:00pm 0 Comments

I haven't flown much of anything because of the weather, so I decided to see if I could do something different with my ArduIMU.  I decided that if I could get a MIDI port to read the IMU, I might be able to make music.

I used a VBscript to read the serial port and send pitch data from the ArduIMU to a slot.  I then used a MIDI program to record the…

The Next Sensor was Invented by Vikings

Posted on March 11, 2013 at 4:00am 2 Comments

There have been discussions before calling for reliable and accurate alternatives to GPS. The Vikings may have had the answer without knowing the physics. They were adept navigators at latitudes where frequent cloudiness and low sun angle(winter) could have made direct observation of the sun difficult. Legend has it that they had a magic stone, called a…

My Ardupilot(legacy) Platform

Posted on May 24, 2012 at 8:41am 8 Comments

Here's the plane I will install my Arduimu and Ardupilot(legacy) into.  I still need to build a motor mount and wind the motor.  It should be stable as it is based on a previous version which was very stable.  I'm aiming for 10-12 ounces AUW and around…
