Resistors and speakers Answered

Hi,

Is it possible to create a 16.5-17Khz speaker output using only resistors? or should I look into a 555 timer? if so, how?

Thanks,
Dan

To add to Kiteman's comment, you can make an oscillating output like that with a 555, the specific word you're looking for is "astable" as a 555 can be used for other types of timed circuit. Search on Instructables or Google (Instructables first, natch) for "555 astable circuit" and you will hopefully also find the necessary calculations to work out the resistor and capacitor values you need.

Only resistors? No.

With a 555? Look to the search box in the top-right of this page. If that fails you, try any major search engine.
