Re: line level signal?
just any old capacitor will do?A blocking capacitor would stop the dc power voltage reaching the other side.

line level signal?
hi i was wondering if someone knew if 3.8v @ 2mA would be too high a line level signal. i read that a nominal line level falls around 1v @1mA but i'm more curious if the numbers i initially stated would be too far out of range and would endanger devices it would be passed on to. the idea i'm working...

Re: use of 1/4w resistors to control a dc motor
ah yes, good suggestion. I just need to take some time and go by ratshack to pick up some other supplies as well.
i'd probably use several as overall tuning pots since i was attempting to have several momentary-on switches to use to control it. already burnt out two pots earlier today

Re: use of 1/4w resistors to control a dc motor
philba: I realize this isn't a very efficient application here but its mostly due to me trying to work with what i have and keep this low-budget[as in $0]. Ideally i would you a micro-controller et.al but alas i am broke. mrAL and Externet, thank you for your help in pointing me in the right directi...

use of 1/4w resistors to control a dc motor
so, I' trying to power starve this motor I'm using[by using a resistance ladder with switches], it's a 12v DC motor rated at 500mA. If I were to do this should I be using a particular wattage resistor? any recommended values? I'm thinking just multiples of 5ohms should work [5,10,15,20,25...] but I'...
