Buildling An Optical Flow Sensor (Arduino + CdS + Shoebox)

Posted September 29, 2012 by Chris

“This device is no match for an Randy’s sensor, but it does (minimally) work. Think of this little project as a fun hack more than anything else. But with some tweaking and size reduction someone could probably implement an occasionally working altitude hold sensor for a fixed-wing RC aircraft.”

A Quick Look At Some Quadcopter Hardware

Posted July 7, 2012 by Chris

“Now the hardware for my Quadcopter and a good portion of the software is complete for the quadcopter. The hardware really consists of 4 parts: The controller board, the quadcopter XBee board, the USB XBee board and the quadcopter frame with motors and ESCs.”

Mikrokopter Octocopter Build Up

Posted April 7, 2012 by Chris

“A good friend of mine, Corey, who lives on the other side of the pond (the US) asked me if I wanted to help building a Mikrokopter Octocopter kit he recently purchased. I accepted right away. It’s not every day you get to build a 2000 dollar multi-rotor platform and compare it to your own 100 dollar platform.”

High Altitude Balloon Transmitter

Posted March 12, 2012 by Chris

“A small group of high school students launched a high-altitude weather balloon with a small payload. In addition to a video transmitter and GPS transmitter, they decided to include a simple transmitter built from scratch. This is the story of the project, with emphasis on the simple transmitter’s design, construction, implementation, and reception (which surprised me, being detected ~200 miles away and lasting the entire duration of the flight!)”

PongSat – Real ‘SpaceBalls’

Posted March 7, 2012 by Chris

“A PongSat is an experiment that fits inside of a ping pong ball. These ping pong ball ‘satellites’ are flown to the edge of space by balloon or launched in sounding rockets. The PongSats are then returned to the student. It’s an easy and inexpensive way to get students excited about science and engineering. There are endless possibilities for experiments that can fit inside a ping pong ball. PongSat’s can be as simple or complex as you want them to be.”

BXFlyer Four Rotor Helicopter

Posted February 21, 2012 by Chris

“I decided to build an autonomous flying robot about three years ago. I’ve converted RC cars to autonomous operation, so I thought that an RC helicopter might be a good place to start. I quickly discovered that the standard helicopter design would probably be too unstable in flight for my simple navigational and programming skills – but in searching the web I stumbled across the four rotor electric helicopter platform…and I was hooked!”

Areoquad: The Open Source Quadcopter

Posted January 13, 2012 by Chris

“AeroQuad hardware typically consists of an Arduino MCU as the flight controller board and an AeroQuad shield with various sensors, such as an accelerometer and gyroscope. AeroQuad software is written in C and uploaded to the MCU via the Arduino IDE. It currently supports an Acrobatic Mode that uses only the gyroscope for flight assistance, and a Stable Mode that uses the gyroscope and accelero-meter for leveled flight assist.”

SkeyeCopter UAV

Posted December 20, 2011 by Chris

“In previous and parallel work with autonomous airships we gained experience with UAV control and autonomous navigation. Compared to airships, the multirotor UAVs we use in one of our current projects are of course much smaller and can carry much less payload. On the other hand, due to their size, they can be deployed a lot faster and do not require any preparation except for connecting the batteries.”

ARM Based Quadcopter

Posted December 6, 2011 by Chris

“The electronics setup consists of an ETT STM32 stamp module which runs custom flight software written in C. The board contains an ARM Cortex M3 microcontroller with 64K of RAM and 512K of flash rom. The board itself runs at 3.3V, but the inputs are 5V tolerant.”

BlimpDuino Version 2

Posted November 19, 2011 by Chris

If you are looking to make some autonomously controlled flying objects, a blimp is steady and slow way to get started. This article shows you how one team modified a toy blimp’s electronics to add some intelligence and autonomy to its flight.
