The cheapest shaft encoder available is inside a serial mouse.Two for a buck in the dollar store. The encoding is well documented,just do a search. Industrial grade encoders cost three to five hundred dollars. The output is a square wave that needs to be processed. Ablolute positioning implies that ...

YOu could try a set of noise cancelling headphones.I've seen them for 30 bucks in Staples. If the sound is still there it's probably in your head.

use an opto isolator so that the chip only sees voltage from it's own supply.

How about a qyro?

that's just his opinion

Since when did kenetic energy have anything to do with gravity? Sounds like sombody is just guessing!

The two pi is already in there. If you have a one foot radius the circumference is 2pi feet. A circle has 2 pi radians so one radian would equal one foot of circumference. It's exactly the same as the linear version. 550 pounds of force at one foot per second.

My professor was unable to speak the day we learned about touque.He was a little horse. When I asked him a question his brow went into a long furrow and he answered in foot pounds.
Now that's horsepower
Sorry just pulling your chain!

How about strain guages on the support straps to measure the weight of the fuel.

Foot pounds and pound feet can be confusing although they are clearly defined. I wouldn't use either one without adding the words "of energy" or "of torque" after them for reinforcement. I don't see how you get from a failure of the English language to "chaos" The real ...

So you are saying that they don't define the same amount of energy? How so?

"100 pounds and one foot are not the same as 100 feet and one pound, and thats why its called the Pound foot, after James Watt meant it to be."<p>They are the same in that both situations define the same quantity of energy.

"A inaccurate expression because you cant have 100 feet, and one pound of force, and call it a accurate term."<p>What makes this inaccurate? One pound of force acting over a given distance sounds precise and repeatable to me.

I don't usually like to get into these peeing contests but I can't resist. I work for an old company who’s turn of the century product was a pump that used the linear force from a steam cylinder to move a piston which in turn pumped fluid. So tell me was it pumping without horsepower or was it produ...

Logic zero outputs can often be around 1/3of the supply voltage. Your circuit may be on all the time. It could also tend to heat your transistor if it stays in a partially on state.
