My (ONLY!) knowledge of electronics: o I can buy parts at Radio Shack if given the part #s. o I can read. o I can follow instructions. o I can soldier. I need to build the follow device: You hit a button on a very small box. 25 seconds later a gentle beep is heard. A second beep 3 seconds later. A third and final beep after an additional 2 seconds. (That's 25-28-30 secs). The unit then resets itself awaiting another button press. Accuracy need only be +/-0.25 second. Sounds simple? -- --------------------------------------------------------- Reply-To: ba@m-net.UUCP (Bill Allen Beogelein) Organization: M-NET, Ann Arbor, MI ---------------------------------------------------------
