I have an idea of building a laser communication between two computers. I was first thinking of using serial/paralell ports but the USB port is almost as easy (I think?) to use. USB should provide more bandwidth (if necessary). You could probably use some parts of the laser thingy you have on this page. But it would use the computers USB (5v?) for power. Thanks for any ideas or links. Spelling bad. Not from US. Björn Lundgren Finland | ||

USB would work far easier than parrallel ports. The only real way to do this is with some kind of serial connection. USB connections run on 5v, I believe. There are quite a bit of wires inside a USB cable, but most of them are for PnP capabilities and Packet overhead. I believe only 2 are for the intended data transfer. Parrallel ports transfer data over many wires, so you would need more than one laser pointer, or some kind of high speed modulator. | ||

If you have an IR connector on the motherboards, lasers and photodiodes could be connected to these with minimal circuitry. If the power output is correct, you might not need any additional electronics at all. | ||

I think it would be easyer with a serial connention anyway what program would u use to tranfer data mabay you modifie a infared conmunication divice and that way if it uses a generik diver everyone would have it | ||

USB cables contain only 4 wires and is much more difficult to interface than a parallel or serial port. | ||

If youre just transferring data and you have it set up so that the info goes right into the computer, try some sort of remote control software to run stuff depending on the signal you get. Other than that you'll have to write your own software just using the COM . LPT port or if you used USB youll have to write drivers. |
