-- The potentiometer is the electrical equivalent of the chemical balance, or balance arm scales.
A current from the dry cell _Ba_ is constantly flowing through the main, or so-called potentiometer circuit, _ABCDGEF_.
However, by purchasing and inserting a miniphone to miniphone "potentiometer" read "volume control" in line with his setup, the output of the record player/stereo reciever can be reduced before the input to the computer.
The acoustic tones from the piezos and the electric tones from the magnetic pickups can be blended together with a constant-grade potentiometer, meaning any combination of the two tones can be achieved from control and blended through the same output.
"potentiometer" or "gynecological," and at times I've been obsessed with trying to recall a word I knew existed but which I couldn't remember for some reason.
Basically ABC proved that if you bypass a potentiometer with a resistor, you can spoof the potentiometer setting.
Tom adjusted the thermograph potentiometer to zero deflection and checked the circuit once more.
I know most of you are thinking: "That is a small motor encased in a plastic tube, attached to a potentiometer and a pushswitch, so that some weird electric guitar player can use it to excite his guitar strings and magnetic pickups and generate an annoying electromagnetic whine."
An MOS transistor in parallel with your power-level potentiometer would be one way to do it, with control at the MOS gate.
I know this may sound daunting but it's a matter of opening up the flash, discharging the capacitor very important i.e life threatening: an analogue voltmeter across the connections will do the trick disconnecting the two wires from the light sensor and soldering them onto a logarithmic potentiometer which will cost you about £1.30 from Maplin.
