right.. so then the next step would be trying to create a usb device, possibly with usb ports, that would be similar to pd turning on and off a certain parameter, such as power. In a sense, it would be like a MIDI controlled, mini lighting rig. I know theater sometimes uses midi to control lights in a automated way.. so something like that.

Hi Robert,
Indeed the AID site is down, I've emailed aid@interaccess.org about it.
What lights are you controlling? How many? Maybe a parallel port would be enough? You could switch the parallel port pins and use a simple circut of tracs and opto-isolators to drive AC current controlled by the computer.
USB seems a little high-level for what you want to do.. Why USB and not parallel, serial, etc??
If your not into building your own system for the lights (or paying someone else to do it) seems a MIDI or DMX lighting control system would be ideal, if you can afford it...

btw, i always wondered what's the difference between zexy's [lpt] object and your [parapin]. do you have an idea? ([lpt] is able to write 2 bytes to the parallel port and read one byte from it; everything is based on messages; usually you use the hardware-addresses of the parallel-port(s) to address it; in the CVS version of zexy you can also use the /dev/parport device (linux only))

In CVS yet? ;)

DMX is the standard theatre lighting control protocol. It is built on
top IEEE485 (I think that's the number, its the updated serial port)
run over XLR cables.

As we enjoy great advantages from inventions of others, we should be
glad of an opportunity to serve others by any invention of ours; and
this we should do freely and generously.
