Long-duration HAB flight in progress

The California Near Space Project is at it again.  Last year, they became the first team to achieve a transatlantic crossing using a latex weather balloon, and they launched from California.  Above is last year's flight path.

They have another long-duration flight over the great lakes right now, and you can follow the action here:  Note that they're having some GPS trouble, so the position…

Aeromapper RTF UAV + APM2.5 + parachute system = easy landings!

Just sharing that the Aeromapper UAV is now ready to order with the new parachute recovery system.

Will very briefly describe a typical mission sequence so the basic setup of parachute + APM2.5 is explained (at the end). We think simplicity is king:

1. Assuming flight mission…

Proof of Concept test - Extremely accurate 3D velocity measurement with a ublox 6T module.


When the ublox 6 series modules were released, I noted that the 6T and 6P modules provided access to the raw carrier phase measurements, and I started thinking about how to use this capability.  My connections through my university research appointment weren't strong enough to get ublox to sample a dev kit to me (they generally don't sample them at all).  Jordi and Chris from were kind enough to use…

I love the new GE "Brilliant Machines" ad. How many robots can you name?

I was lucky enough to be part of GE's launch of their "Brilliant Machines" campaign, around the Industrial Internet and the intersection of ubiquitous sensors and big data. You can see the event here, including my own conversations with GE's Jeff Immelt and VC Marc…

Report from the DroneGames (formerly Drone Olympics ;-))

We had a a great time at the Drone Games at the Groupon offices in SF today. (They used to be called the Drone Olympics until they got a cease-and-desist from the Olympic Organizing Committee). Nine teams competed, all using Parrot AR.Drones running Node.js…

Fixing a 3DR frame weakness

One of the weak spots of the current 3DR frames is that the aluminum walls of the arms are very thin. The motors mount directly to the arm and in the event of a "landing anomaly" the aluminum wall is easily deformed by forces on the motor.

My solution was to construct "backing plates" for the motors. The plates fit inside the arms and slightly longer screws are used to attach the motors through the plates. The plates are simple 1/16" aluminum sheet drilled to match…

Raspberry Pi Quadcopter

Raspberry Pi is a superpowerful and popular new computer board, like Arduino but with a much faster processor and built-in video. It's not really designed for "physical computing" with lots of I/O like Arduino, and it's not open hardware so you can't make a version optimized for any particular task, so…

Arducopter build

I've been building a new Arducopter recently. Here are the ingredients:

  • RC Timer X650 frame (with Xaircraft cowl iso the supplied transparent dome)
  • RC Timer 30A ESCs with SimonK firmware
  • AX-2810Q 750KV motors with integrated prop adapters
  • GF1245 (12x4.5) props
  • APM2 with…

Autonomous Waypoint Flight Mode in SmartAP!

Now SmartAP autopilot has Autonomous Waypoint Flight Mode. The demo shown in the video above consisted of 4 waypoints. After the last waypoint quadcopter came back to the initial home position and automatically switched to position hold mode there. Moreover, autopilot has Stabilize,Altitude Hold, Position Hold and Return to Home flight modes. Flight can be controlled…

Experimental Airframe - Goldschmied Pusher

Hi all,

I've only recently become part of the diy drones community and already I've learned a lot about amateur UA operations.

As my first contribution here I thought I'd share a design that I put together this morning based on some old research on laminar flow shapes.

It's a bit…

The DIY kid-tracking drone

Nice job by IEEE's Spectrum's Paul Wallich in creating a DIY "follow me" box (working with ArduCopter) to keep an eye on his kid on the way to school. Sample from the article, which appears in print this month:

On school-day mornings, I walk my grade-school-age son 400 meters down the hill to the bus stop. Last winter, I fantasized about sitting at…

CO2 Parachute System

I know that people have discussed this before, but I have yet to see anyone declare that they built a worthwhile system or create any documentation.  I did see some youtube videos using pyro charges, but that makes me nervous.  I want to use CO2.  If anyone has any information or observations I would love to hear it as I start this project.  I am throwing all my ideas out there to see what people would do differently, or to find out if it is a pipe dream (pun intended).  So here we…
