Machine

Published May 19, 2015 | By DonLuc

A machine is a tool containing one or more parts that uses energy to perform an intended action. Machines are usually powered by mechanical, chemical, thermal, or electrical means, and are often motorized. Historically, a power tool also required moving parts to classify as a machine. However, the advent of electronics has led to the development of power tools without moving parts that are considered machines.

A simple machine is a device that simply transforms the direction or magnitude of a force, but a large number of more complex machines exist. Examples include vehicles, electronic systems, molecular machines, computers, television, and radio.

Electronic Devices

Vacuum tube, Transistor, Diode, Resistor, Capacitor, Inductor, Memristor, Semiconductor, Computer.

Robots

Actuator, Servo, Servomechanism, Stepper motor, Computer.

Electronic Machine

Electronics is the branch of physics, engineering and technology dealing with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes and integrated circuits, and associated passive interconnection technologies. The nonlinear behavior of active components and their ability to control electron flows makes amplification of weak signals possible and is usually applied to information and signal processing. Similarly, the ability of electronic devices to act as switches makes digital information processing possible. Interconnection technologies such as circuit boards, electronic packaging technology, and other varied forms of communication infrastructure complete circuit functionality and transform the mixed components into a working system.

Ontrak ADU208 – Mk1

Published May 14, 2015 | By DonLuc

ADU208 USB Relay I/O Interface ( Dimensions, 5.1″ X 2.8 X 1.0″ )

The ADU208 USB Relay I/O Interface allows control of 8 relay contact outputs, 8 contact or TTL inputs, and 8 event counters via a USB port. The ADU208 can effectively convert a standard PC to a powerful PLC ( programmable logic controller ). High quality PA-Series relays from Aromat offer superior performance. This low-cost serial relay contact interface is easy to use with VB, VB.NET, and Visual C++ via standard HID drivers included with Windows 98,2000,XP. A mini-driver ( DLL )* is also provided allowing control using standard ASCII commands using familiar readfile , writefile commands. The ADU208 includes a 10′ USB cable and is available as a PCB or in an enclosure with several mounting options.
