I've checked about and can't find any reasonable way of doing this. The best thing to do is to find an old computer (in a dump/junk shop) and remove it's power supply. This will provide a high current regulated output of +5 -12V and +12V. -- From Jamie Dainton Friday, September 15, 2000 15:32:19 The Bat! 1.46 Beta/5 Windows 98 4.10 2222 mailto:pgp@dainton.org.uk?subject=sendKey -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
