This instructable will show you how to design and build a circuit using truly tiny SMT devices.
Electronic Design Automation (EDA) tools, and traditionally allow you to draw out a symbolic representation of a circuit using
a schematic capture interface, (sometimes) simulate it with a circuit simulator, and then finally lay out the circuit on a printed circuit board (PCB).

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.

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.

A blazing coating lets microscopic carbon nanotubes generate electricity
Engineers at MIT have devised what they call a new way of producing electricity. By coating a microscopic carbon nanotube with
a layer of fuel and igniting one end with a spark or laser, they're able to send a wave of heat shooting through the nanotube's interior.
This
thermal wave pushes electrons in its path, generating a significant electric current. Prototypes already have energy density 100 times
greater than lithium-ion batteries, and they can be stored indefinitely without leaking charge. The researchers are now investigating optimal
fuels and, to make the system reusable, will have to invent a way to automatically apply a fresh layer of fuel after the first burns away.
How It Works:
1. Heat the Tube. One end of a microscopic carbon nanotube, coated with reactive fuel, is ignited by a laser.
2. Herd the Particles. A wave of heat races through the inside of the tube, pushing electrons toward the other end.
3. Harvest the Energy. The movement of the electrons forms an electric current.
