Hi-

I need to build some sort of a flasher to put on my dog's collar- she's the
same color as the carpet and keeps getting stepped on :-) I'm thinking a
3909 flasher running a LED from a coin cell. I haven't kept up to date on
what's available, or if there are any better chips than the LM 3909 out
there. Ideally it should be able to run for a year and be small enough to be
clipped onto the dogs collar without having a honking big battery hanging
off it (ideally the thing has to be smaller than the dog, which is pretty
tiny). Any suggestions appreciated. TIA.


Get a bigger dog ?:-)

.... or dye it purple. (;-)
