hmmm...this might be useless to ask since noone responded to my original question, but...
I have treads on my robot, but they are slipping off the wheel hubs. Does anyone know of some sort of correction device that can keep the treads on the wheels?
thanks,

I think the easiest to interface is the parallel port. And at 8 bits, you could easily set it up to control 2^8 LED's. You just interface then decode the address into LED matrix address.
there are MANY parallel tutorials on the web...epanorama.net (the best!)
good luck,

Lets take it step by step...
first: current flowing from + to - or - to +,...that is the question....it depends on who you talk to. Old school electronics guys like to say +to- ..acadamia will teach that it goes from -to+, because that is the actual direction the electrons flow...so your...
Thats the funniest/stupidist thing i have heard!
How about a low tech solution to a low tech problem?
You could use a remote switch, or long power cord?
Make a touch switch (if its close).
If you really want to do it by computer i say the easiest way is to get one of those X10 setups...
How remote do you need it?
My first thoughts are a pully and string system, that will raise the door. Use a simple infrared emitter/detector circuit to trigger the motor that will turn and wind-up the string, opening your door.
You could be a few yards away when you "trigger" it.
Yes, i was thinking some sort of microphone input, a low-pass filter (active most likely) to eliminate unwanted signal,...feed that to a comparator that you have configured for a minimum level (you dont want a quiet signal trigering it).
You then will take the compatator ouput to a one-shot...
Some boards have special setups, so you will need to look at each boards documentation or specs if they have it. In general though they will work like this:
( i will note each hole with a capitol letter, similar letters mean there is a connection(i.e. shorted out))

Just to end the thread on this one,...i have decied to drill a #22awg sized hole where i need a via,...and put in the hole a piece of stripped #22 wire,...then solder both ends
Somewhere on https://www.epanorama.net you will find a schematic that uses the Maxim MAX038 chip.
this is exactly what you're looking for.
p.s- Maxim provides free samples :)

Not only is this probably the wrong forum, but what you are asking is missing about a dozen steps.
You will not be able to pipe your external hard drive to a tv without MAJOR design work.
What you can try to do is buy a video card with tv-out (like ATI All-in-Wonder), then use a program on...
Wow, here is an amazing amount of information right up your alley!
**broken link removed**
let us know how it turns out...(or which project you decide to do:)
What is your final goal?
I have thought about your idea before and i came to the conclusion that it would be useless.
Considering you could connect them with an interface that could connect their pci busses, you still would only have about 66MHz of bandwidth. That is really useless to try...
Are you wanting to build a circuit to get a feel for putting it together and debugging and such?...or are you wanting to design one from scratch?
If you just want to build some circuits you should try Radio Shack's "Engineering Series" books. They are little USA$2 books with projects to learn...
