I want to make my own usb based data acquistion module, and try interfacing it with labview? Now I have a few questions, since i am quite new to it: Where do I get started? Can I do the interfacing(with labview) via parallel port ? or serially ? Can the Module be made using PIC...

Hello, Im having problems with my circuit, I am using a quad comparator IC (LM339N) but for some reason the output its generating does not seem to change with either changing inverting or non inverting inputs. I mean, the output, remains same even when the non inverting input (+) is less...

@berkeman: Yes .. a walk-through metal detector

I want to use an "inductive proximity sensor" for metal detector gate, but the problem is its range is (generally) under 50mm (2 inches), is there any way I can increase its range? or is there any alternate sensor or way to detect the metal ? Thank you. Faraz Nizamani

I have no other data regarding the question :/ can you help me ?

This is bugging me for some reason .. can anyone help me with this ? the current flowing through an element is i= {2A, 0<t<1 2t^2, t>1} calculate the charge entering the element from t=0 to t=2 second

I don't know how magnetic polarization can account for defining logic levels ? as with each spin quantum number (1/2) the logic level shifts, I am just confused about the application of spin polarization within discrete electronics..

Can any give me a general idea of what is Spin Polarization ? and how can spin polarized electrons define logic levels(Spintronics) ? Faraz Nizamani
