UAV

Besides other stuff, I'm experimenting and developing with UAV technology from 3D Robotics. Here's some interesting stuff and tips & tricks.

Sometimes there's just no good place to mount the external LED to on a copter or one simply wants more light output... While developing my own little light controller, I wrote a decoder which decodes the I²C control signals for the external LED and controls arbitray amounts of Neopixels accordingly.

This is the first version of my mode switch holder for the Taranis. It fits the Hobbyking / X-Rock mode switch. It mounts in place of the left slider (I pretty much never use the sliders). A hole to route the cables is included in the design. This version still is a little bit close to switch E. Still doing some fine tuning.

After just a few flights, the FrSKY telemetry of my IRIS suddenly stopped working. The Taranis was not updating the display or it was showing nonsense values, like altitude -65535 or similar. Time to do some diagnosing.

Last Friday, I was preparing for a rather simple auto mission. I set everything up, did a last minute change to CH7_OPT, then positioned my IRIS on a nice place for takeoff. I armed in LOITER and raised the throttle. The IRIS lifted off to about 50cm and started drifting to the right. I tried to steer against with no effect.

On June 26 I got another nice package from Flight Illusion with new gauges to work on: GSA-40 Gyrocompass, GSA-20 IAS indicator, GSA-23 VSI and a GSA-72 General Aviation Clock. GSA-40 and GSA-72 got ready today. The gyro was pretty simple but the clock took quite a bunch of hours due to some interesting quirks in it's own control protocol and some MAVLink peculiarities. Next up are the IAS and the VSI - probably at the weekend. Videos will follow soon.
