Updated to UAVX
I initially built this is 2007 – things have moved on now and this is so out of date, who’d ever have to make their own frame now. Anyway, they are called bloody drones now and well…
It’s a Quadcopter built from an Open Source development, more info here: http://uavp.ch/moin
Although most of the tech and help came from this forum: http://www.rcgroups.com/forums/showthread.php?t=811550
Here’s some pictures of how I created it:
The main structure is made from Sign Board, it’s very thin alloy with plastic bonded, very light and strong.
It’s white so I used vinyl gunmetal and red.
I put O’Rings between the delrin blocks I made to give some damping
The cage hand made from alloy
Booms from a 450 helicopter
Modified the leg of carbon rod, fitted 5.8Ghz video sender custom built and a Canon SD450 (Ixus 55)
I used a remote camera device for the FlyCamOne (FC02) with the modified CHDK Firmware on the Canon to get remote shutter working through a USB lead, it needs 5v on pins 1 and 4.
All worked well until I connected the video out for the camera, I found that the FC02 switched the ground not the live, the video jack is grounded so when plugging that in triggers the shutter.
I made this simple circuit with an old transistor to change this around.
FC02 plugs onto pins
CHDK Firmware, set to run a simple remote shutter script on auto
5.8Ghz video transmitter made on veroboard
Because of the 2mm pins on the RX unit I had to make my own PCB
Experimenting with antennas at moment.
