Re: Simple LED Alarm Bell for CCTV recorder

[Crash Gordon® <NONE@xxxxxxxx>]

LOL... no its two separate projects..the led thing is for an alarm =
idea..the fiber is for my daughter's science project (one reason I don't =
wanna spend $$ on it...they get thrown away 10 seconds after their =
presentation is finished).

Wyoming...beautifull..but way too freekin cold.

Thanks for the link to Newark.
