My housemate built a very nice Quadcopter. I got drunk and decided that it needed a beer dispensing add on.
Works fine with his remote but haven't had the free time and weather to test it yet. Oh and I should probably get around to making a little beverage parachute. And I'll take some better pictures and maybe even make a little tutorial at some point...
Pringles are a crisp that come in a tube, in case you didn't know.
Micro Servos which are cheap as 'chips'
2x 3 of them (3 pins per servo)
I decided to power servos from a 9v battery to avoid unnecessary stress on the flight controller
It seems to work fine but I need to make a parachute for the beer before we test it, otherwise we might kill a granny or infant with our falling beverage.
Josh has also suggested adding ANOTHER servo to tilt the tube into position before opening the 2 micro-servos to release the alcaholez. I'm not sure what the point in this is but it will look AWESOME so I'm going to try it.
Anyway, heres a video of it working at ground level and dropping a beer onto a pillow…
