A Review of 3D Printing Services: Shapeways, 3D Hubs and Makerbot In-Store Printing (for PX4 and Pixhawk mounts)

This review compares three 3D printing services available to me in the New York City area, all of them local and two of them able to ship. I had them all print a set of anti-vibration mounts for the awesome PX4 and Pixhawk flight controllers from 3D Robotics. The cost of the service and the quality of the output differed more than I expected, and…

Brushless gimbals are so outdated : try live "Body control technology" to stabilize your camera (Drone's humor hour)

I bet 3DRobotics could never produce those! That's what I'd call perfect gimbal stabilization technology : no soldering required, no battery and it flies.

Grassroots Drones/UAVs for Disaster Response in the Philippines

xUAV1

I was recently introduced to a new initiative that seeks to empower grassroots communities to deploy their own low-cost xUAVs. The purpose of this initiative? To support locally-led disaster response efforts and in so doing transfer math, science and engineering skills to local communities. The "x" in xUAV refers to expendable. The initiative is a partnership between California State University…

Getting to 100km, with a big help from GEB 8043125.

Today we decided to finally get out of the office and go fly !

I wanted to test a new pack which has been sitting on my desk for a while, a 14.8V 4s4p 24400mAh. 

This is a different type of lipo , with a energy density of 262 Wh/kg. 

Simply, this battery has an energy density which is x 1.62 of regular lipo (160 Wh/kg), which can help you get long flight…

A twoview 3D reconstruction

Click for big!

In the last post just two days ago, I talked about the fundamental matrix and a homography which allowed 2D images to be warped in such a way that they overlap. That technique works a bit better if you take the photos from the same…

Trappy talks flying, regulation, and starting a business

Trappy, this one's for you!

Jeff Bezos at Amazon hasn't done it. Nor has Fred Smith at FedEx or Scott Davis at UPS. No American CEO has persuaded Washington to relax its chokehold on commercial drone use in the United States. But this month a 29-year-old Austrian entrepreneur living here in Asia broke Washington's drone…

NCR18650B - Flight Testing

Last week I did some bench testing on the NCR18650B Lithium Ion cells, and the results were very promising, showing twice the energy density as a LiPo. This week I wanted to get the packs out of the lab and in the air on the Raptor 100 for some real life testing.



First I tested what…
