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.
Full box of .240 Weatherby Magnum, loaded rounds. I threw them in with the rest of a bunch of stuff I picked up thinking they were new but upon closer inspection, they appear to be reloads so I'm selling them as components. Plus the box is pretty cool.
$30 plus shipping at actual cost to buyer.
70 plus rounds of 300h&h hand loads that need to be pulled down for components
I am not liable if you shoot this ammo I did not load it. Don’t know who did

Starting to Down size all my gun stuff. Sold my last 25-06 and now need to sell off the last of the components and ammo. Here's what I have, 25-06 rcbs dies,,,, box of 120 gr partitions,,, 14 rem 100 gr ammo,,, 8 Winchester 120gr ammo,,, 64 rounds of 100 gr ballistic tip components...
Hello,
This is a box of ammo I bought at an estate sale/garage sale at the height of the pandemic/riots when ammo was hard to find. I bought it for the 7.62x39 that came with it. Has sat in my closet the last few years just taking up space. I learned later this is all probably reloads (I was...
Reloaded ammo for sale. This came from a friend's estate and is being offered as components only. Shoot at your own risk. Prices are as follows:
9mm .20 per round
45 ACP .25 per round
223 .40 per round.
I can post pictures if anyone feels the need. FTF in the Lebanon area. Please PM me...
Four boxes of projectiles
A bunch of brass.
I will get a tally on the brass when I get a chance. Or feel free to rainman the picture and tell me how many are there.
im open to cash offers I doubt I will turn down a solid cash offer

The shotgun is in excellent condition. Only 100 rounds have been through this shotgun. Very low mileage.
I am the original owner. It comes with the Nordic MXT Extension kit installed, $153 invested. The shotgun can carry 9 rounds.
Asking price is $900 cash only, priced to sell.
