Whiteboard

Weight target is 500g, Payload 250g, Lift 250g
* Arduino 27g
* esc 22g
* motor 38g (spec)
* propeller 7g

27+4*(22+38+7)= 295? (268 for motor + ESC)


~30/01/2013
* Link -> WIFI
* no gps (http://www.ebay.com/sch/i.html?_nkw=pci+5s&_sacat=0 if we finally need one)
* Beaglebone/linux + arduino
* motor load ~ 7 amps @ ~ 250g lift
* safety/testing -> glasses, net
* regular workshop schedule -> every wednesday 7-9
* next meetup -> 6/2
* -> smaller quadcopter 
* budget -> ?

~Tasks
* Beaglebone linux distribution, rt-linux & related stuff
* Investigate existing open source DoF/quadcopter platforms
* Investigate propeller mounts and/or motors 
* Look at quadcopter kit prices

~Ideas
* Buy quadcopter kit (cheaper ?) to get us started
