"Technically it should go from nose down to nose up or left roll to right roll. In practice good question. I will try it out and see if the SkyWalker uses the force or comes tumbling down. Cheers Justin"

Netduino - It actually worked....

Surprising but true - no blue screen of death and it didn't do a spiral of death into the rolling hills of Hertfordshire. Hardware:Netduin Mini - Code in C#DiyDrones MuxArduImu v2 No fancy pid loops just some ugly code and lots of hot glue.Since it worked well enough at bringing it all back to level flight i will  try some way point fluff next. Did i mention how ugly it was: private static…See More

"All the code is custom written in C# and held together with sticky tape. On the hardware side its the Atom as the main processor with an Arduimu talking to some Netduino Minis and lots of wires....."

In progress APM/UDB Mission Planner

Posted on August 26, 2010 at 5:00am 7 Comments

Yet another mission planner in the works, i dont personally use either AP as i am creating my own.

As part of my dabblings i am creating an offline mapping tool etc for my GCS which i though might be useful to others. It's written in C# and leverages a fair few different map sources and caches the images to disk for offline use.

Needs .net 3.5 framework to run.

Right click to drag the map.

Grab it…
