Workshop 03/07/2013, by All
- Flashed Debian 7.0 (Wheezy) on Beaglebone.
- Installed and tested two different wifi dongles.
Workshop 05/06/2013, by ododos
- Added joystick input to udp client-server program
- Decided to send joystick data as is (16bit signed integer) and do any post processing on board
- Flashed Ubuntu image on Beaglebone, connected via ssh and uploaded udp server program
Workshop 29/05/2013, acinonyx
- Moved forward on sockets with a basic client - server example made and presented by acynonix
- Decided to use IP/UDP stack for control communication
- Made network latency tests that gave an average of 16ms over 3 hops in our lan
- Decided to abolish the, now redundant, identifying 2 bits used for serial communication
Workshop net-pre-meetup 27/05/2013, skmp
- Explained some stuff in the code
- That was all, really
Workshop 22/05/2013, etc

Workshop 17/05/2013, mkir
- Decided tag for mailing list -> [hackopter]
- Played a little more with github
- Attempt to connect XBOX joystick on linux
- Saw new revisions of hackopter logo! Nice! ;)
Workshop 08/05/2013, petros.kon
- 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
