  • Project Name set : Hackopter
  • Team name (guess) : Hackopter-team
  • Team members registered at hackerspace general discussion mailing list
  • Primer on github git and git uis

Workshop 01/05/2013, skmp

  • +3 new team-members
  • Talked about general direction and organisation stuff
    • We'll focus a bit on the tooling (git/github/mono/gcc) so that everyone is familiar before moving on
    • No name chosen still
    • Round-robin event coordinator. Next one is petros.kon

Suprise event @ nasa space days 21/04/2013

  • skmp -> we now have xbox360 + wii nunchuck for experimentation
  • Hacked together C# control ui (slimDX + serial IO)
  • Hacked together arduino control software (sucks badly)
  • A few (very) unstable flight tests !

Workshop 17/04/2013

  • Flashed firmware on KKmulticontroller v5.5 board
  • Calibrated ESCs
  • Completed setup procedure of multicopter
  • (click on the title for the detailed event page)

Workshop 03/04/2013

  • Resolved ESC/BLDC soldering issues by drilling new holes (the quad is now slightly smaller, non destrutive change)
  • Finished assembly

13/03/2013

  • X525 arrived at hackerspace.gr
  • Checked motors
  • Soldered motor contacts
  • Assembled main body

Team (sorted by nickname)

  • (edit this and add yourself *AND KEEP IT SORTED*)

TODO List

Mods

  • Add more nuts on suspension legs
  • Add rubber bumpers on suspension legs
  • Use more washers

Wanted stuff

  • PSU that can handle the load

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
* Crazyflie Nano Quadcopter Kit: http://www.seeedstudio.com/depot/preorder-crazyflie-nano-quadcopter-kit-10dof-with-crazyradio-bccfk02a-p-1365.html?cPath=170_172
