The big flaps at brussels

on vimeo

• demo routine and some building
• a medium testing setup
• an early testing setup

the miniflaps in the hackerspace

you'll find them on 'flappers.0x20.be' or simply 'flappers' from within the space

the raspi driving the flappers runs the flapservice on port 1337, you can connect as follows:

• interactive session using netcat

nc flappers 1337

once connected, hit enter and let the flappers explain how to interact with them, multiple people can connect at the same time.

• sending a simple message:

echo "foo" | nc flappers 1337

more commands and special characters:

• '$clear' you guessed it
• '$iread foo' is used for callibration, eg. if the flaps read 'crt' but you just sent 'cat' then you need to send it '$iread crt' to straighten it out
• '@@@@', the @ character is used for the special position that forms '0x20' with the four flaps, this is the standby position
• lowercase is white, uppercase is red
• '$quit' will shut down the pi, dont do that, just exit the interactive session using ctrl-c
• theres no digits, and a few special characters, just try and see

initiating a shutdown on the pi will try and put the flaps on 4 blanks first
