About Me:
Enthusiast for all things flying, and the best flying things are the ones you make yourself. I started building my first quadcopter in 2009 because it was just as expensive as a coaxial heli, I got to build it myself, and it was computer controlled. As a budding computer engineer I couldn't have found a better platform and project.

My talk at 'Drones +Tech'

Posted on April 1, 2014 at 3:05pm 2 Comments

Someone reached out to me a few weeks ago to 'give a talk on drones.' I talked briefly about MEMS, ring-laser-gyros, and touched on social issues and how you can short circuit the conversation when you can own the tech and do it yourself.

See the other talks from the night here at the IFTF.

Taking the New Bird Out for Turkey Day

Posted on November 24, 2012 at 3:25am 2 Comments

Hiking Sweeney Ridge on Thanksgiving morning was a perfect time for testing out my newly completed quadcopter.

This spot in the mountains, 1200 feet over SFO and the Pacific ocean, seemed like a perfect place to test out my newly completed quadcopter and my newly acquired piloting…


ARM7 mini quad with xbee remote

Posted on January 23, 2011 at 2:00pm 16 Comments

Using an Phillips NXP LPC20148 ARM7 processor, a Nintendo Wii motion+, and some xbees I've made a really stable platform for quads. (mode details here) It is running FreeRTOS which makes it very expandable in the future. My old frame flew great with it, but I wanted something smaller.…


Novel means of quadrotor control / adjust

Posted on August 28, 2010 at 11:11pm 7 Comments

Here's the demo of my gamecube remote controlling my quad. Newly implemented is the ability to adjust the PID.P value on the field using just the remote.

This method can be implemented with the analog remotes most people use. I've got another remote that uses only analog sticks to drive a menu system. Something similar could be done for the main AeroQuad project if anyone is interested.

The idea was that I wanted a durable,…

Hi Tim
Is there a place that you have posted the hardware requirements for using a game controller with the Ardupilot mega ,i`m assuming that’s what you are using in your quadcopter , is there anything else beside the 2 whey XBee ?

Hey man, I'm a history major. I think I met you last semester at the Applied Engineering meeting. I remember you brought your quad copter to show off your potential. I'm interested in how you got your game cube controller to work as your R/C controller.
