now heres a tool you might take for granted, but it tends to be in near constant use!, a quick verification on size of a component can do wonders for your sanity, at times. I can,t begin to tell you how many times I find parts, especially the cheaper imported parts that are dimensionally a total $%^&* joke, and when you take the time to check, you find out why many import parts are a waste of time to install.
now I,m certainly not saying having AMERICAN MADE parts will totally guarantee you won,t have issues but it certainly tends to help.

ID suggest most mechanics could use a 6-8" version and a 12" version, the cheaper digital versions are reasonably accurate from what Ive seen testing them against my more expensive versions but keep in mind your mikes are for, fine, measurements are taken with your micrometers,

not the caliper, thats just used to get a real good idea of the ball park measurements when you don,t really need precise , measurements,
like when your measuring brake rotors where a .001 difference means next to zip!

Ever wondered how digital calipers work? They are based on a capacitive array that can senses motion accurately.
Here's a good wite up on the subject. http://www.biotele.com/digital_caliper.htm

Interesting article.....thanks Bytor!

It seems these sensors can pickup on alot of other things also, wonder if they can sense a woman's mood ??? :p

Capacitive sensors can directly sense a variety of things—motion, chemical composition, electric
field—and, indirectly, sense many other variables which can be converted into motion or dielec-
tric constant, such as pressure, acceleration, fluid level, and fluid composition.

Interesting article Bytor.
SIN & COS Plates I believe are abreviated from Sine & Cosine.
Amazing the technolgy hidden under that black blob of sealant epoxy.
At least 100,000 NPN & a few PNP transistors working together as logic units & operational amplifiers or OP Amps.
AND , NOR, NOT gate logic circuits at most basic electronic circuit levels.
And a quartz crystal regulated oscillator signal generator operating at 100,000 Hertz or 100KHz.
Dictates internal baud communication rate & mathmetical computation rate.

Thanks for article shared.
