Soundcard spectrum scope


Recommended Posts

I was wondering if any1 knew how to make a scope that could measure frequency through the computer's soundcard.  I saw one before, it utilizes only a potentio, capacitor, then the aligator clip and tester stick... it was then plugged in the sound card...

then a program was used. no wori bout the program, theres lots everywhere... just the ckt of the scope... tnx.

that is a much more complicated scope.  i also found that while searchin the web.. I would just like the basic one.  I'm pretty sure that it only consisted of a:

10k potentiometer...
one of the pins was attachd to an alligator clip (for the ground)
one to the the tester stick (for the positive)
the other to the female audio jack...

then there was a capacitor sumwer between 2 of the pins...cant recall where or what.

and lasltly, a male audio chord, to the PC s.card and the female jack.. thats it.

Thanks anyway.... :)
