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
• 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
