Electronics comprises the physics, engineering, technology and applications that deal with the emission, flow and control of electrons in vacuum and matter.Electronics is widely used in information processing, telecommunication, and signal processing. The ability of electronic devices to act as switches makes digital information-processing possible. Interconnection technologies such as circuit boards, electronics packaging technology, and other varied forms of communication infrastructure complete circuit functionality and transform the mixed electronic components into a regular working system, called an electronic system; examples are computers or control systems. An electronic system may be a component of another engineered system or a standalone device. As of 2019 most electronic devices use semiconductor components to perform electron control.
The identification of the electron in 1897, along with the invention of the vacuum tube, which could amplify and rectify small electrical signals, inaugurated the field of electronics and the electron age.Commonly, electronic devices contain circuitry consisting primarily or exclusively of active semiconductors supplemented with passive elements; such a circuit is described as an electronic circuit. Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes, integrated circuits, optoelectronics, and sensors, associated passive electrical components, and interconnection technologies.The nonlinear behaviour of active components and their ability to control electron flows makes amplification of weak signals possible.
Electrical and electromechanical science and technology deals with the generation, distribution, switching, storage, and conversion of electrical energy to and from other energy forms (using wires, motors, generators, batteries, switches, relays, transformers, resistors, and other passive components). This distinction started around 1906 with the invention by Lee De Forest of the triode, which made electrical amplification of weak radio signals and audio signals possible with a non-mechanical device. Until 1950, this field was called "radio technology" because its principal application was the design and theory of radio transmitters, receivers, and vacuum tubes.
The term "solid-state electronics" emerged after the first working transistor was invented by William Shockley, Walter Houser Brattain and John Bardeen at Bell Labs in 1947. The MOSFET (MOS transistor) was later invented by Mohamed Atalla and Dawon Kahng at Bell Labs in 1959. The MOSFET was the first truly compact transistor that could be miniaturised and mass-produced for a wide range of uses, revolutionizing the electronics industry, and playing a central role in the microelectronics revolution and Digital Revolution. The MOSFET has since become the basic element in most modern electronic equipment, and is the most widely used electronic device in the world.
The study of semiconductor devices and related technology is considered a branch of solid-state physics, whereas the design and construction of electronic circuits to solve practical problems come under electronics engineering. This article focuses on engineering aspects of electronics.
Hey all, I’ve been hunting high and low for months for brass for my 300prc and I finally found a honey hole for components.

For the record, I’m not trying to promote this guy or his business. I’m just trying to help frustrated people get the stuff they...
I have 61 rounds of 10mm ammo loaded with lead cast bullets. I don’t know who loaded it and would recommend pulling it apart.
Asking $10 for all of them.
I am cutting back on my reloading so I have a lot of reloading components for sale. The easiest way to show what I have is in the attached pictures. I have rifle bullets to include .223, 6mm, 6.5 mm, 270 cal, and 30 caliber along with pistol bullets in 380, 9mm, 10mm, 41 cal and 44 cal. I...
Mainly 9mm range pickup ammo, also some 40, 45 and 223 included
At least 200 rounds of 9mm
Not sold to be shot. For those who have time on their hands to pull the bullets and reload them.
$25 (think primers...) or free for any NWFA Gold Supporter or above

Caliber purge in progress. I looked up the current prices on all these, sale price reflects 50% of current price. In some cases they are not in stock. The Amax bullet price based on the equivalent ELD bullet as Hornady discontinued the Amax line.
Will meet in the Vancouver area, near Safeway on...

680 rounds of 30 Carbine ammo, my reloads so let the buyer beware, I am selling this strictly for the parts. I used to have a Blackhawlk in 30 carbine but no longer have it so the ammo needs to go. I shot quite a lot of this with no problem but again, it is best to dismantle the ammo. The...
These appear to be heavy round nose bullets, but they could well be anything.
My guess would be 170-190 grain but i haven't had any time for disassembly and weighing of any of this.
