Apologies for the video in portrait, hope it is still visible.
True to the DIY element of this community, I've devised a small, cheap and simple way to attach items of any kind to my Quadcopter and via a servo to release it.
It's quite simple yet effective, using one servo and some pieces of metal and a screw to mount it underneath my hexa (custom frame built entirely from 3DRobotics parts).
You can see I have been doing a lot of bending to get the right angle etc. Now that's DIY! ;-)
Photos from three angles:
With one switch I can now release anything I'd like to transport around, e.g. Waterballoons, Cupcakes, Parachutes etc.
I had all the parts necessary already lying around and the build is really simple. I had to bend a lot of the small metal parts into the shapes I wanted them using simple pliers.
I had been racking my brain about such a thing for a long time, and today was the Eureka! moment.
Hope you like the idea!
