First, try checking with your local library. They can probably help you find the article and get a copy for a photocopy charge. If that doesn't work, the ARRL has and archive of Ham Radio: http://www.arrl.org/members-only/qqnsearch.html If THAT doesn't work, and you still have the authors call sign,...

Have you ever sold something? What did you charge? Could it have been as much as you thought you could get? Oil is $78 a barrel because someone is willing to pay $78 a barrel for it. Oil, like everything else, goes to the highest bidder. People with SUVs bid a lot. ...That and because Bush is paying...

So called "starter caps" do not provide a starting current "kick". They provide a current phase shift between different sets of windings in the motor, which sets up a differential magnetic field, which in turn causes the rotor to turn.

I agree that what you probably want (for this particular task) is a logic analyser. I was horrified that you assumed a sampling rate was an issue. It is of course an issue if you are limiting yourself to a DIGITAL Scope. However, not all scopes are digital. In the olden days, like the latter half of...

I believe that --Computer Grade-- is a marketing term that has little technical meaning. If it means anything at all, I think it means that the manufacture believes the part is appropriate for use as a power supply filter cap in a computer where the output of the switching power supply has a conside...
