Modding a Wikipad for use as a ground station

Hi all,

I got a Wikipad (an Android tablet that targets gamers) to experiment with as a ground station / second TX, mostly because it has dual joysticks. There is a lot of work to be done until it has RC-controller like capabilities. First step was a workaround for the design flaw that no USB data ports are exposed when you have the tablet snapped into the…

Afterflight: A browser-based system for analysis and annotation of video and sensor data from UAVs.

Several months ago I started working on a system called Afterflight to organize and browse my tlogs and dataflash logs, sync them with video, and view them along with a map GPS display. It still has a long way to go, but there is a fair amount of working functionality so I figured I'd get it out there for comment, warts and all. I would love to see it flourish as a…

Fun with FLIR (detective work on melting FPV goggles)

I've started flying a lot of FPV recently, and I noticed that my Fat Shark Base glasses were getting quite hot after just minutes of use. Using my lab's handheld thermal infrared camera, I took some photos of the goggles and my quad after a few minutes in the air partially to try and troubleshoot the heat problem but mostly just for fun.

The goggles…

ArduCopter on an Antarctic volcano

Hi all,

It occurs to me that I never got around to posting my videos flying my ArduCopter, Cindi Lou, on Mt Erebus last December (2011). I'm at around 10700 ft, but the pressure altitude is around 0.65 bar -- the equivalent of closer to 13,000 ft at the equator. This was on a nice, warm (-15C) nearly windless day. I was pleasantly surprised how well the quad…

Four ArduCopter flights in a row before crashing!

After a rough start last month, my ArduCopter CindiLou showed what she could do today. See the attached video for four flights. In the first three the camera is pointing at the Cindi, and in the fourth I have mounted the camera on the forward landing gear so you get to see a rather dramatic crash from the quadcopter's POV. The wind was blowing quite strongly to the…

What to tighten and what not to: my first baby steps with my ArduCopter


I've now gone around one full circle on the UAV wheel: I built her, flew her, and crashed her. It has been great fun so far and I can't wait to get in the air again. Before I do, however, I thought I would write something so that other beginners could learn from my mistakes.


Anticipation and Assembly

I decided sometime last April to buy an ArduCopter spent several months in breathless…
