Circuit Diagram
A Circuit Diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the different components of the circuit as simplified standard symbols, and the power and signal connections between the devices. Arrangement of the components interconnections on the diagram does not correspond to their physical locations in the finished device.
How to test a Uni Junction Transistor?
A Uni Junction Transistor (UJT) is an electronic semiconductor device. It is made of a lightly doped (high resistance) silicon bar, which can either be an n-type or p- type. It is a three terminal device with characteristics very different from the conventional 2 junction, bipolar transistor. It is a pulse generator with the trigger or control signal applied at the emitter.
In-Circuit Emulator
An In-Circuit Emulator is a hardware device used to debug the software of an embedded system. It is usually in the form of bond-out processor which has many internal signals brought out for the purpose of debugging.These signals tell about the state of a processor. Embedded systems present special problems for a programmer, because they usually lack keyboards, screens, disk-drives and other helpful user interfaces and storage devices that are present on business computers.
Introduction to Embedded Systems
An Embedded System is a special-purpose computer system designed to perform one or a few dedicated functions, sometimes with real-time computing constraints. Embedded Systems span all aspects of modern life and there are many examples of their use such as digital watches, dishwashers, microwave ovens and washing machines.
Diagnostic Devices
There are a lot of different devices with which we can test and diagnose electronic equipment. We use some of them to measure voltages, currents, and components in the circuit and others as stimulus of the circuit and the remaining to analyze the response of the circuit.
Evil Genius - Resistor Attack Game
The 'resistor attack game' is a fun variant of the space invaders game designed to help you learn the resistor colour code. This game has been donated to us by Mr Cutcher who has written the book Electronic Circuits for the Evil Genius. You can find more informatino about Electronic Circuits for the Evil Genius at elexevilgenius.com , there are also other freely available downloads like the winscope software that allows you to use your soundcard and PC as a basic oscilloscope. Click on the title to get to the download page.
Simple Choc Block Supply
A very simple adjustable power supply can be built on a single piece of chocolate block based on the L200CV IC. The output is variable between 0 and 30V, with an adjustable current limit up to 2 amps.
