Free Energy Lemon, Orange or Potato Battery

A lemon battery is a simple battery often made for the purpose of education. Typically, a piece of zinc metal (such as a galvanized nail) and a piece of copper (such as a penny) are inserted into a lemon. The lemon battery is similar to the first electrical battery invented in 1800 by Alessandro Volta, […]

CNC Computer numerical controlled Lathe and Swiss-style Lathe

Computer numerical controlled (CNC) lathes are rapidly replacing the older production lathes (multispindle, etc.) due to their ease of setting, operation, repeatability and accuracy. They are designed to use modern carbide tooling and fully use modern processes. The part may be designed and the tool paths programmed by the CAD/CAM process or manually by the […]

Metal Lathe or Metalworking Lathe

A metal lathe or metalworking lathe is a large class of lathes designed for precisely machining relatively hard materials. They were originally designed to machine metals; however, with the advent of plastics and other materials, and with their inherent versatility, they are used in a wide range of applications, and a broad range of materials. […]

Lathe Machine Heavy Duty Manufacturer

A lathe is a machine tool which rotates the workpiece on its axis to perform various operations such as cutting, sanding, knurling, drilling, or deformation, facing, turning, with tools that are applied to the workpiece to create an object which has symmetry about an axis of rotation. Lathes are used in woodturning, metalworking, metal spinning, […]

Telescope view of the universe

A telescope is an instrument that aids in the observation of remote objects by collecting electromagnetic radiation (such as visible light). The first known practical telescopes were invented in the Netherlands at the beginning of the 17th century, using glass lenses. They found use in terrestrial applications and astronomy. Within a few decades, the reflecting […]

Joule thief or not joule thief that is the question

A joule thief is a minimalist Armstrong self-oscillating voltage booster that is small, low-cost, and easy to build; typically used for driving light loads. It can use nearly all of the energy in a single-cell electric battery, even far below the voltage where other circuits consider the battery fully discharged (or “dead”). Hence the name, […]

Solar Power – Free Energy Generator

Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics convert light into electric current using the photovoltaic effect. Photovoltaics were […]

Homemade HTPC – Turn a Raspberry Pi Into an XBMC Media Center

The best home theater PCs are small, quiet, and inexpensive—so the bite-size, $35 Raspberry Pi is the perfect choice. Here’s how to turn this little DIY board into a cheap, silent media center in just a half hour. Check out the video above for a quick demo of what the project entails, and what you’ll […]

Raspberry Pi – New mini PC for Children

The Raspberry Pi is a series of credit card-sized single-board computers developed in the UK by the Raspberry Pi Foundation with the intention of promoting the teaching of basic computer science in schools. The original Raspberry Pi and Raspberry Pi 2 are manufactured in several board configurations through licensed manufacturing agreements with Newark element14 (Premier […]
