Driver, PC LPT and power supply schematicas

[msnarouz]

Hello
I'm now looking for schematics for the driver , LPT o/p and power supply
I need to make these circuits I don't want to buy
Any help?

One of the best resources is www.pminmo.com It is by Phil who posts on this board, and is an excellent resource for home built drive circuits, breakout boards for interface to the LPT and also has links to power supply circuits.

What is a break out board ?

[NC Cams]

Break out board (BOB) = takes the DB25 pins from LPT port and "breaks them out" so you can more easily hook wires to them via screw or solder terminals.

Some of the better BOB's use optical isolation to prevent damage to/from LPT connnecting to external circuitry.
