Or do you want a lab-type supply with regulated voltage and smooth current limiting? It sounds like you don't have a tremendous amount of experience with electronics -- you may find it helpful to get a copy of the ARRL handbook, which has some nice power supply designs as well as a _lot_ of good practical basic knowledge. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com Do you need to implement control loops in software? "Applied Control Theory for Embedded Systems" gives you just what it says. See details at http://www.wescottdesign.com/actfes/actfes.html
