As for creating your own USB device...good luck.  I'm sure it's possible, but it would require both making your own circuit and programming it as well.  

I thought about the LED idea as well, ronin.  Maybe someone here with a tad more knowledge about electronics could alter the circuit to incorporate an LED?  I'd imagine you'd need a simple IC to translate data coming from the IR module into switching some type of transistor to power the LED, but I dont' really know :-/

Another Question if the IR device only has two legs, have I totaly got the wrong thing or am I not doing something right.
Also the diode symbol, does it matter which way it goes? seeing as it is pointing one way. (As you can tell I have no clue about this sh*tz)

diodes are polarized.  

in this diagram:

-->|--

the | side is the negative side.  just think of it as a LED (well since LEDs are diodes anyway).  you will see a band on the diode to represent the |.  if it's glass, it's black.  if the diode is black, the band is white/silver.

if your IR device only had two legs, then that's most probably not a receiver, but a transmitter.  if it is a receiver, then it's not the right one.

yea tis a recive and only has two legs, rollocks.
Oh well.
RE the diode uh, how can you tell which is the right side, its SOOOOO small I can hardly see whats written on the thing.
It glass and has one red side and a trasparent side.
Is the red side the positive?

Bugger, and I have just solderd in all the bits.
DAmn it! :(
Snow Veil, seeing that you are ofey (SP) With electronix could you incorperate the added feature to this feature...
So I dont have to unsolder it all and waste the money I spent on the bits I got for this project.

Well, thanks to the help of viridius and linear, I think we've got a working model.  Really it shouldn't be too hard to set up, and I've ordered the parts already so I'm just waiting on them to arrive.  We'll see how it turns out.

Pretty much we're just going to take the Data base of the IR module, solder a large valued (~40kohm) resistor to it, solder that to the base of a transistor, then solder the emitter of the transistor to ground and the collector of the transistor to an LED, then that led to a ~100ohm resistor that goes to the 5v line coming out of the regulator.  It sounds more complicated than it really should will be.

Standard Serial Cables??
« Reply #38 on: March 14, 2004, 04:33:56 PM »

I want to use a standard serial cable for this project but I don't have a multimeter to find the correct wires in the pinout. Are the colours standardized in every serial cable? If so, can someone let me know the colours for pin 1, 5 & 7 in a standard 9 pin serial cable?

And yes I have googled and not managed to find the info....

bitbyter: another way to do that, grab two cables, solder a 470ohm 1/4W resistor on one of them, then solder a led to the other side of the resistor and to the other cable.
Plug that cable to 12V, you can get it at any molex.
The led will tell you when you're touching the same cable. ;)
