I posted a couple weeks back about making a cheap power supply for my breadboard, now I want a cheap clock signal generator. What's the easiest way to go about this, other than manually moving the clock wires from high to low?

the simplest answer to your question is the most popular IC chip in existence, which literally every EE knows about and which has hundreds of pages dedicated to using it.
HINT: it rhymes with "hive hive hive"

Don't skimp on the supporting RC network either, you'll want accurate values if you're trying to anything time-related.

True, the 555 is cheap and easy to use for simple applications, but its output isn't the cleanest you can get. If you're doing something more timing critical, you'll have togo with a good oscillator.

digikey.com <clock chip>, cheap - 4 pins (power, gnd, out, enable)
from 32.768 khz to 100Mhz.
555 sucks for accuracy (just find a temp stable cap....wtf?)
otherwise get an epileptic to hold some wires and wait.
