I learned a few years ago in an Ethics and Social Responsibility class that most electronics, computers and mobile phones have a component that is made using slave labor. I’m not sure whether it’s an element that is mined or something else. But I’m sure that such a thing exists and that slave labor is [...]

Resistor: multimeters have resistance scales. You can directly measure the resistance of a resistor.
Capacitor: Some multimeters have capacitance capability. If not there is a little that you can do. First verify that there is "infinite" ohms. If not then the cap is probably shorted. If it is a high enough electrolytic then you can see [...]

With this hands-on electronics course you will learn the fundamemental operation of basic electronic components by comparison to drawings of equivalent mechanical parts.

I found the book at a used book store, and I’m trying to place a catalog order for all the parts I need. Anyone have a list or recommendations?
Radio shack sells a really good electronics learning lab kit: two lab books full of projects. You get everything you need with this kit , proto boards [...]

It’s for GCSE and I’ve built a simple pressure pad alarm but what can I add to it ? I’ve already got an oscillator, logic gates, some memory, a high pitched buzzer and push switches for inputs ( of course, 1 to act as the pressure pad and the other as the reset button for [...]

None — It is a cable — so there are no other electronic components apart from the cobber wire which are inside the cable.
All the electronic components which make the USB work are inside the computer and your PC — the cable just provide the electrical connectivity for the signal to be transferred between the [...]

Audiophiles have known for years that the power coming through the AC line is full of interference and line disturbances that degrade audio reproduction. Dirty power is also caused by radiated high frequency signals, such as those coming from broadcast stations, or even your own video and digital components. You only have to see the [...]

I want a recommendation for a "brick and mortar" store that has a good variety and inventory of electronics components on hand in the store. I am looking for a place in or near downtown Washington, DC. Radio Shack is not sufficient. If you’ve walked into one lately, it’s clear that low-level [...]

Accessories that go with the latest home theater equipment offer additional aesthetic enjoyment for the consumers.
