[PD] Usb lights

[B. Bogart]

hi,

Well unless these lights are desinged to be controlled from the computer
you will not be able to use them and would have to build something
yourself. (or pay someone to do so)

If little LED lights are what you need then such a circuit should not be
too hard, but if you have only USB ports on the machine then controlling
LEDs would not be too easy, without something like the multiIO, being
more expensive than those USB lights.

Now if you can find a USB light that someone designed to be
controllable, and the company is nice enough to tell you how to control
it without enrolling in a developer program then you may have a chance.

>>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.
