questions?[edit]
ask sasja
The big flaps at brussels[edit]
on vimeo[edit]
the miniflaps in the hackerspace[edit]
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
