Scope Soldering Iron
The "Scope" soldering iron is a tool for soldering with lead-tin alloys, made in Australia since 1950, and intended for occasional or intermittent use. It has the virtue of quickly coming up to soldering temperature (~300C) and delivering considerable heat to a small area, but requires care to avoid overheating. It operates on low voltage (3–6V) and high current (tens of amps) from a battery or suitable transformer, so is by design electrically safe, and as it cools down rapidly when it leaves the operator's hand, should not constitute a fire risk. Principle of operation The soldering iron's " element" is a small carbon tip at the end of a pushrod connected to one terminal of the power supply, inside the stainless-steel barrel of the tool, but insulated from it. The barrel and its copper tip (the "bit"), is connected to the other terminal. When the user operates the pushrod, the carbon element bears against the back of the "bit", resulting in electric heating of the resistive ...

Electronics Work Tools
Electronics is a scientific and engineering discipline that studies and applies the principles of physics to design, create, and operate devices that manipulate electrons and other electrically charged particles. It is a subfield of physics and electrical engineering which uses active devices such as transistors, diodes, and integrated circuits to control and amplify the flow of electric current and to convert it from one form to another, such as from alternating current (AC) to direct current (DC) or from analog signals to digital signals. Electronic devices have significantly influenced the development of many aspects of modern society, such as telecommunications, entertainment, education, health care, industry, and security. The main driving force behind the advancement of electronics is the semiconductor industry, which continually produces ever-more sophisticated electronic devices and circuits in response to global demand. The semiconductor industry is one of the global ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hand Tools
A hand tool is any tool that is powered by hand rather than a motor. Categories of hand tools include wrenches, pliers, cutters, files, striking tools, struck or hammered tools, screwdrivers, vises, clamps, snips, hacksaws, drills, and knives. Outdoor tools such as garden forks, pruning shears, and rakes are additional forms of hand tools. Portable power tools are not hand tools. History Hand tools have been used by humans since the Stone Age, when stone tools were used for hammering and cutting. During the Bronze Age, tools were made by casting alloys of copper and tin. Bronze tools were sharper and harder than those made of stone. During the Iron Age iron replaced bronze, and tools became even stronger and more durable. The Romans developed tools during this period which are similar to those being produced today. After the Industrial Revolution, most tools were made in factories rather than by craftspeople.

Warren And Brown
Warren and Brown, often styled W & B, was an Australian company known for manufacturing hand tools for the automotive and engineering trades. Founded in 1947, it was taken over by Repco, an Australian engine manufacturing and reconditioning company, and under their management continued manufacture and development of products aimed at suburban automotive workshops. In 1985, in a major restructure, Repco sold W & B to a small group of investors, in what was termed a management buyout, and continued to operate, manufacturing a diverse range of products. History The company was founded in 1921 by Andrew Canfield Brown and company secretary William Howard Warren ( – 24 March 1947), as jobbing engineers, in premises at 119 Ballarat Road, Footscray, Victoria. In 1930 the business was restructured as "Warren and Brown Pty Ltd, ironfounders, mechanical engineers, and manufacturers of machinery, etc." valued at £5,000, as 5,000 £1 (one pound) shares, owned equally by the two principa ...

Bruce Small
Sir Andrew Bruce Small OStJ (11 December 1895 – 1 May 1980) was an Australian businessman and politician. In Melbourne, he developed Malvern Star bicycles into a household name in Australia, then retired to the Gold Coast, Queensland, where he developed property, and as Mayor of the Gold Coast, promoted the area to Australia and the world as a family-friendly holiday destination through the bikini-clad meter maids in Surfers Paradise. Background Bruce Small was born in Ryde, New South Wales, in 1895. At the age of 24 in 1920 he bought an interest in the Malvern Star shop at 185 Glenferrie Rd, in the Melbourne suburb of Malvern, from Austral Wheel Race winner, Tom Finnigan. His brothers, Frank, and Ralph Small, joined Bruce in his sales, building cycles at the rate of 5 per week. The small cycle shop offered prizes in cycle races, resulting in Hubert Opperman winning a prize in 1921, and impressing Small so much that a job was offered to the young cyclist. Thus started a ...

Nickel–cadmium Battery
The nickel–cadmium battery (Ni–Cd battery or NiCad battery) is a type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes. The abbreviation ''Ni–Cd'' is derived from the chemical symbols of nickel (Ni) and cadmium (Cd): the abbreviation ''NiCad'' is a registered trademark of Saft Groupe S.A., SAFT Corporation, although this brand name is genericized trademark, commonly used to describe all Ni–Cd batteries. Battery (electricity)#Wet cell, Wet-cell nickel–cadmium batteries were invented in 1899. A Ni–Cd battery has a terminal voltage during discharge of around 1.2 volts which decreases little until nearly the end of discharge. The maximum electromotive force offered by a Ni–Cd cell is 1.3V. Ni–Cd batteries are made in a wide range of sizes and capacities, from portable sealed types interchangeable with carbon–zinc dry cells, to large ventilated cells used for standby power and motive power.

Solder
Solder (; North American English, NA: ) is a fusible alloy, fusible metal alloy used to create a permanent bond between metal workpieces. Solder is melted in order to wet the parts of the joint, where it adheres to and connects the pieces after cooling. Metals or alloys suitable for use as solder should have a lower melting point than the pieces to be joined. The solder should also be resistant to oxidative and corrosive effects that would degrade the joint over time. Solder used in making electrical connections also needs to have favorable electrical characteristics. Soft solder typically has a melting point range of , and is commonly used in electronics, plumbing, and sheet metal work. Alloys that melt between are the most commonly used. Soldering performed using alloys with a melting point above is called "hard soldering", "silver soldering", or brazing. In specific proportions, some alloys are eutectic — that is, the alloy's melting point is the lowest possible for a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
