computer<-->world connections

There are three new tools in the shed. List:

1. a Max/Jitter patch that will advance full resolution video frames while driving the Tobin through a whole roll of single frames film. Call it an automated digital optical printer
2. a Boarduino and prototype shield for interfacing with generalized MIDI streams
3. an interface to John Fletcher’s Integrating light meter (for lumpy time)
3. a plugin for chatbots that automates the jkerouac teletype project. News on that follows

The serialdaemon [http://cs.gmu.edu/~sean/cs685/uploads/Main/serialdaemon.c.zip] code allows me to route connnections on an arbitrary tcp port directly to the serial port. Now I can connect to that port and send characters to the tty-connect board for printing out on the teletype. First, compile serialdaemon.c
gcc serialdaemon.c
mv a.out serialdaemon
chmod 755 serialdaemon
mv serialdaemon /usr/local/bin/

  1. connect the keyspan and fire it up:
    serialdaemon -serial /dev/tty.KeySerial1 -baud 38400 -port 10001 -indebug -outdebug

the only problem with this scheme is that it depends on the serialdaemon’s host being available from the Internet (ie, possessing a static IP). You could add another layer by putting the chat parser on the same host. Like this

[ Internet ] < –> [ ircbot -> chats -> cleaner -> rater -> filter -> serialdaemon ]

so the serialdaemon host needs to be a little smarter and more muscular than I had originally planned, but it makes for a more flexible framework.

I’m a bit fed up with Tcl and the eggdrop daemon. It’s solid enough but I don’t want to have to parse logfiles for periodic diffs. I would rather run a bot written in a familiar language that allows me to build a plugin. That plugin could then parse each line of chat and pass it to the rater. High-scoring lines could then be forwarded to the waiting port for output to the serial daemon and subsequent printing on the teleytpe.

Great! now how do I write a plugin? This one talks directly to the serial port obviating the need for a serial daemon. If everything’s going to live on one machine, this is probably the way to go.

class Rater(callbacks.Plugin): """Add the help for "@plugin help Rater" here This should describe *how* to use this plugin. """ threaded = True def __init__(self,thresh=50,db='/Users/dgoodwin/code/kerouacs_ear/_dbs/kerouac.bay'): self.db = db self.TTY = serial.Serial('/dev/tty.KeySerial1',38400) self.TTY.write("\r\n ! ! ! ! ! ! !
