Simple Oscillator Circuit?
Simple Oscillator Circuit?
Hey, I need a simple oscillator circuit for this art project I did but never finished...and well I have a portfolio review soon and figure I should get it up and running soon...555 timing chip maybe? I don't know...Thanks!

This looks really cool and useful:

More involved, but even more useful:

haha well the first time i was just really messy about it and the second time i managed to wire it upside down heh...so i fixed it and it's going now...just gotta fuss with the frequency a bit and drop the output a bit...i put a trimpot in where one resistor would go so it has some control to it...i'ma put another one at the output to tame it down a lil bit...dumb mistakes are always the ones to get me
weeeee
A 9 volt battery should give you 500 milliamphours. So if you have an amp meter, you can stick it between your battery and circuit and get a total current draw. Divide 500 by the number of mA drawn, and you'll get a rough guess at how many hours it can run.
If you don't have an ampmeter you can try to calculate the current usage by hand. The manufacturer probably lists a maximum current draw on some spec sheet too.
