About how much would it cost to build something for me to control about 10-15 positionable mini-LED lights with pd? Robert

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?"
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.
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.
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:

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 ...

i assume with "positionable" you mean led's attached to a lead that you can place elsewhere. if you mean to have the position controlled by usb as well, that woul make things more complicated, of course.
the cost for that would be around 30 euro in parts. you can save a lot when you request the microcontroler as sample from microchip.
you would need a chip, a usb socket, a crystal, two capicators and some pinheaders to connect the led's to, all mounted on a perfboard. if you want to drive more than one led at once (i.e. connect 5 led's to one output), you need to add a transistor and two resistors per output. for ten outputs, add another 5 euro for the drivers.
you need to buy the parts yourself and send them to me, if you want me to build it for you. all you need to include is the postage to send the stuff back, plus whatever it is worth to you that i build it for you. thats all.
if thats ok for you, contact me off-list, i send you a partlist then.
greetings,
chris
