APM-eye's view of News Interview

Here's an interesting bit from a recent news interview with me and Andreas... for my segment, I had parked the quad so that it would be visible in the background over my shoulder as I talked to the interviewer.  While he was recording the quad, the quad was recording him!

If I would have planned ahead a bit I would have framed the shot better, but I…

Working on an IMU

I decided to work on a new IMU, and I decided to design my own so I could get a higher update rate, higher processing power, some more noise immunity, and I like designing my own systems as opposed to buying them :)

 Here is what I have on board:

-500 MIPS XMOS L1 Processor

-12bit 1MSPS ADC

-3x ADIS16060 Gyros

-ADXL335 Accelerometer

-HMC5843 Magnetometer

-Ports for…

Windsock - Wind speed and direction iPhone app

I've been a DIY drones member since at least 2009. I have a couple of sites I likes to fly at but packing the flight gear and driving down to the park only to find it's too windy to fly can be frustrating. Instead I built this app to drop windsock markers down on a map and get the latest wind readings for a near-by location so I know if it's great weather to…

APM2 conversion to Naza

Morning everyone!

So i decided to try the whole Dji thing. It took all of about 20mins to swop the APM2 with the Naza.

The setup is as simple as it gets. That took no more than 10 mins.

After installing the hardware and software I took it outside and attempted the first flight.

All I have to say is wow! A truly awesome…

Flying Wing Testing - No Stabilizers and Expos

While adding the AMP to the Shrike, we wanted to understand Flying Wings a little better and explore expos.  We incrementally increased expose to 0%, 30%, and 60%, then flew the Raptor with the existing vertical stabilizer at 100%, 50%, and 0%. We were surprised to find that it flew just fine with 0% stabilizer! This test was in low wind, however, so it will…

One piece 3D-printable glider

Just a hint of what's to come. You'll need to use PLA, not ABS plastic, and it's a challenging print, but just imagine what will be possible as 3D printing technology improves. The design files are here.

Video of printing and flying:…

Mould Plug CNC Machining for HDwing4

Since the topic of CNC mills has raised its head here, I thought I'd share this with the DIYDrones community.

One of the things those who are considering this need to be aware of is that the toolpathing of complex shapes isn't a trivial exercise.  I would be interested to know if anyone has experience with any open-source surfacing toolpathing packages - please comment below! 

I am fortunate to have access to MasterCAM V9 - old-fashioned as it is - but…

My Ardupilot(legacy) Platform

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 50W.

Good Hobby CNC Machine

I'm thinking seriously about getting a CNC.  Been browsing on Ebay.  Mostly these China made 3020 cnc machines are popping up, and they all seem to  be relatively well priced.  Just thought I'd get some opinions from members on any actual experience on these.  Also any…

Flaperon Trial

With much excitement I found some time to give my dual setting flaperon system a test run. In the video, it's used during the low altitude and climb out at the beginning, the landing, and a couple other points along the way. It does feel a bit better for landings and launches, but I think I might increase the 'flap' angle to the full throw of the servo to get the…
