What about this... I just remembered that i have a joystick that connects to the computer via a 15-pin plug. to accomodate more modern computers, it came with a usb-to-female 15-pin connector... would that be the same as having a 15 pin port on the compy, allowing me to use "little LED lights?" I assume there would have to be some sort of driver or something, or a pd [object]. I have no knowledge of creating drivers, or circuits, but would be willing to learn.

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.

I was thinking about these type of lights: http://www.thinkgeek.com/computing/accessories/5a84/ 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@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...

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.
-Robert ps. the link you gave me didn't work for some reason.

but I think CK is right that indeed usb lights are probably NOT comtrollable at all, probably just feed >>the power lines of the USB port to the light. I don't think you can issue a command to tell a >>computer to turn the power off on a given USB port.

no. the adapter you have is only usable for your joystick. usually, those adapters are nothing more than 2 plugs and some wire. there is (usually!) no translation between usb and the other port happening. the device itself (in this case the joystick) can already use usb, the chip inside it will do that. it is the same as with mice: they come with a usb plug attached, and a usb -> ps/2 adapter, but its the mouse that can do usb and ps/2, not the adapter.

the multio that im doing is probably a bit overkill for you (unless you plan to control more stuff with your computer in the future). you mught want to take a lokk at this here:
http://www.create.ucsb.edu/~dano/CUI/
if you are unable to do that simple circuit yourself, i would be happy to help you with that. here i have all the needed stuff like programmer, iron, etc... you just need to send me the parts & stuff so i can build it for you.
of course the same is true for everybody else ... if you need something electronic, but cant do it yourself, ask me ..... im sure we will find a way ...
