[PD] Usb lights

[robertgarvin at bellsouth.net]

I was thinking about these type of lights:

just ones you plug into the compy, and they get the power to turn on. why i'm using usb? because I'm on a dell laptop, and the only ports are usb, s video, a second monitor, and then some weird lookin port...

Hi Robert,

Indeed the AID site is down, I've emailed aid at 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...

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.
