I'm a beginner in electronics and my knowledge is pretty basic. I've been trying to understand how the Octopus Component Tester Works. I know that it's outputs should be used to plot a Current x ...
Please refer to the attached Images. Dimensions: Hieght and Breadth: 42mm Thickness: 25mm I know its PT 1k Ohm resistor(Positive Temperature Coefficient) and its two connecting wires are ...
I am studying electronics and I am currently reading/working my way through "Make: Electronics" by Charles Platt. Here is one of the circuit diagrams that he gives for making a basic burglar alarm: ...
When thinking about substituting components, I know that resistors are easily substituted within their 10%/5%/1% tolerances. But what about wattage on a resistor? Is it safe to do substitutions, say ...
I'm trying to solder together a small LED array with a dimming knob out of a bunch of old parts I have laying around, but I can't seem to identify how to wire this component: The two connectors at ...
Possible Duplicate: What's the best way to store and categorise resistors/capacitors/ICs/etc? I have MANY resistors and many other components as well and currently I am using a very ...
The values for resistors in a typical series, like E12, follow an exponential series (hence the "E"?). 10, 12, 15, 18, 22, etc., everybody knows them by heart (at least E12). But often you want simple ...
I've got one of these cabinets, which I intend to use for storing electronic components: It has 24 drawers (each 175 x 69 x 37mm). Every drawer can be subdivided into up to six compartments by ...
I have an analog audio project I'm playing around with designs for and it will need about 150 solid-state variable resistors. I plan to control these from a micro controller so a digitally controlled ...
I did a big cleanup of my collection of parts today and I now have a big pile of parts on my desk (the majority of which is resistors). My previous method of finding the resistor value I wanted was to ...
