I found this white stuff covering parts of the circuit board for my cell phone. What is this stuff? Do I need to clean it off or something?

What is an electronic circuit called that would work like this (for example):
you have a knob the circuit and a servo. you turn the knob and the servo mimics the motion of the knob.

basically I am looking for schematics an information I can use for the control of a simple telemanipulator. just a simple (relatively) copy cat mimic circuit. the controller moves and the manipulator moves. any Ideas what to look for?
is there a name for this type of controller?

okay, i have two port that i can connect with…
its written there GND(ground) and Vout…
so, which one is -ve?

Looking for circuit board repair for instrument cluster or a new one. Can anyone lead me in the direction or know someone who can help me? Much appreciated.

I am requesting support from someone who knows electronic power circuits. I have an AC adapter, input 120VAC, two outputs: 32VDC & 16VDC. I connect a voltmeter to either output and when I plug it in, output is instantly correct but then slowly reduces to zero asymptotically. It will not deliver any output again until is it unplugged and plugged it again. It then jumps to the correct output, then repeats the slow reduction to zero. I know enough to suspect that the slow fade-out is a DC capacitor discharging but beyond that I don’t know what components to check or how (other than one-way continuity of diodes, resistance of resistors, etc. I have completely eliminated the possibility that it’s a faulty connection or power cord.

you please send me any circuit diagram to my mail id ;b_vignesh@ymail.com
[OR]
tell me the website so that i can find
[THE CIRCUIT SHOULD BE SIMPLE AND SHOULD BE USED PRACTICALLY]
TELL ME THE MATERIALS REQUIRED TOO

Will there be a problem if I plug a window AC unit into the same electrical circuit as electronic equipment such as computers and home AV gear? The closest outlet on another breaker is 20 feet away through a door and this room needs additional cooling in the summer. the unit is rated to only draw 5.3 Amps normally so it shouldn’t blow the fuse, but I don’t know if the compressor surge/voltage drop when it kicks on will harm the other electronics.
