search around the general hardware talk section. also around the site. Johnny has a basic schematic to use but all you really need is a AA or AAA or N batter, a momentary switch an IR LED and some wire to connect it all. (sans container of course)

Details, details. Things to do. Things to get done. Don't bother me with details, just tell me when they're done.
