[sdiy] synth uses for LM3909

[anthony]

I used to have an LM3909 LED flasher that I played with when I was a kid. I 
was lamenting the fact that I seem to have lost it somewhere over the years 
and wondered what synth uses it might have had. So I thought I'd just check 
and see if they had them at Mouser. It's like $11.50. That seems like a lot 
for such a simple little chip. So should I just cherish fond memories and 
say goodbye to the LM3909 and just stick with 555's (and 556's and 558's)?
