Here is a charge pump board I currently build: http://www.mattshaver.com/cp2estop/cp2estop.htm The web page isn't finished yet, but there is a schematic showing the use of an optoisolator. The board sells for $47.50, but I gather you are pretty much intending on a DIY course of action ;) Thanks, Matt ------------------------------------------------------------------------------ Oracle to DB2 Conversion Guide: Learn learn about native support for PL/SQL, new data types, scalar functions, improved concurrency, built-in packages, OCI, SQL*Plus, data movement tools, best practices and more. http://p.sf.net/sfu/oracle-sfdev2dev _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
