Greetings All! wayneg@ican.net wrote to me letting me know about an article in EPE magazine dealing with tachometers. If anyone had the schematics for building this device that would be great. I have found the magazine in the states here, very good stuff! Backissues are available, but I hate to order it for one article @$6 :](I'm shall we say a bit "thrifty"). Thanks in advance, Allen P.S. This list is a usefull source of info and I have learned a lot over the past couple of weeks. Even to a newbie! thanks again.
