DIY Lightspeed Passive Attenuator An optocoupler volume control! What makes this one neat is that optocouplers are used in the circuit. The optocoupler consists of an LED and Light Dependent Resistor (photocell) in a sealed unit. So by varying the intensity of the LED, you can adjust volume. Also, the volume control has no “contact points” in the signal [...]

World's first transistor Dec. 16, 1947, three physicists at Bell Laboratories in Murray Hill, N.J., built the world's first transistor. William Shockley, John Bardeen and William Brattain had been looking for a semiconductor amplifier to take the place of the vacuum tubes that made radios and other electronics so impossibly bulky, hot and power hungry. They were so instantly certain they'd found their answer that they didn't speak a word of it to anyone for six months, until they could experiment further and apply for patents. Then on June 30, 1948, they held a press conference in New York City. They showed the world not only a big model of a transistor but also a TV and a radio with transistors in place of the tubes. Nobody was talking about anything like computers yet, but it was a first look at the future we all live in. The world's response? The New York Times ran an item at the bottom of its "News of Radio" column on page 46. |

HOW TO WIRE-WRAP Wire wrapping is a means for making connections between circuit components using 30g Kynar wire wrap wire and a special wrap tool. The tool forms the wire in a tight spiral around the 0.025 inch square wire post. The post must be square in cross-section because the corners of the square dig into the wire to form a gas-tight connection.

Understanding electricity (water analogy) Beginner overview of electricity, using the water analogy... What do
you think? Electricity seems very difficult for most people to understand. You can't properly see it, you can't properly feel it and you can't taste it or smell it so what is it? It travels quite well through metals and generally poorly through non-metals. It doesn't behave quite like anything else. But this is not quite true: fluid flowing through a system of pipes can behave in many respects like electricity flowing in a circuit. The'obvious'exception to this is that if you pierce a pipe full of water, the water comes out. Try piercing the insulation and touching the conductor: you will soon find the electricity coming out! The main difference is that water will fill any space whereas electricity will'fill'only a conductor. Yes - the analogy is not perfect, but it is helpful and understanding will come not only from the similarities but also from the differences. 4QD-TEC: Electronics Circuits Reference Archive.'The Electronics Club' |

The aim of this
instructable is not to give you a complete guide on breadboard but to show the basics, and once
these basics are learned you pretty much know all you need to so i guess you could call it a complete guide but in a different sense. Anyway
I
will only be using an led and some resistors .. A Breadboard is a board with which you can insert components without soldering them. This make them ideal for test circuits'. |
