Note that the LM3909 has been discontinued, and is starting to be hard to find. It certainly costs more than a dollar now from most suppliers, now that supplies are getting low. (It's now $5.49 from American Micro Semiconductor, rather than the "about a dollar" mentioned in the article.)

I found another wiring diagram at http://hw.metku.net/colorfade/index_eng.html that uses the LM324 which is cheaper than the LM3909.Posted by diremonk on September 22, 2005 at 18:49:02 Pacific Time
