[sdiy] inexpensive chips for oscillators (still learning...)

[Dave Kendall]

You probably know this already, but if using 555s, go for CMOS versions 
(7555, TLC555 etc) which draw *far* less power. It's my understanding 
that the regular 555 can cause problems with power consumption when 
switching.

cheers,
Dave
