As a final plea for help, let me explain my situation, I work for a non-profit organization that produces touch screen based educational software for cancer patients. One of the problems that we are facing is that we need a solution to a problem that we have been having with adjusting the sound...
Edit: I originally started out with a 25 ohm potentiometer and I couldn't get it to work. I think the current on that line has a really low rating. I say that because it can power a set of small headphones (ipod) but it will not even budge a 4 ohm speaker on it's own.
Thank you very much, Would Any of these Work? http://www.futurlec.com/PotRot.shtml
Particularly, 1/2W Dual Logarithmic Taper Potentiometers?
any Help would be much appreciated.
As it turns out I was wrong. The B500K pot is probably matched for the impedence of the speakers in the headphones, but not for the line out of the computer. I know it can be done, I just don't know what resistance the
Pot should be.
I'm Sorry, But I don't know what you mean by 20R. Are you refering to resistance or a 20 R Pot?
I found something that might work. I cracked open a set of headphones we use for the field at work and it
had a B500k Stereo Pot in it. I couldn't find any here in the USA (or I just didn't know where...
Hello,
I'm trying to build a mechanical or analog volume control for computer generated audio.
Trouble is that I have no idea what the resistance or impedence should be on the the pot.
I found something at Amazon that works...
