How To Select My Car accessories And The Features Of My Car PC

It should be said that there are different between the Car PC and the common desktop, which is dependent up on the function of the car pc and the car environment. Functionally, I think the main board computer has the following functions: 1, audio and video entertainment. Can play MP3, DVDRIP movies, audio and video files, you can stop the course of such person or vehicle to the driver, passengers

Stereo to Mono Converter Based on FET

High quality portable unit, Suitable for Subwoofer amplifiers This simple circuit mixes two or more channels into one channel (e.g. stereo into mono). The circuit can mix as many or as few channels as you like and consume very little power. The mixer is shown with two inputs, but you can add as many as you want by just duplicating the "input sections" which are clearly visible on the schematic.

How to build Mains Operated LED Circuit Schematic

Here is a simple and powerful LED circuit that can be operated directly from the AC 100 volt to AC 230 Volts mains supply. The circuit can be used as mains power locator or night lamp etc.. The resistor R1,R2 and capacitor C1 provides necessary current limiting. The circuit is sufficiently immune against voltage spikes and surges.parts D1 = 1N4007 D2 = 1N4007 D3 = 1N4007 D4 = 1N4007 R2 =

How to Use Triacs for Controlling Inductive Loads like Transformers and AC Motors

A Triac is a semiconductor device used for switching AC loads. Normally it is recommended that the loads that needs to be operated through triacs should be resistive in nature, meaning loads which incorporate coils or capacitors heavily, must be avoided.Therefore in general loads which convert energy into heat like incandescent bulbs or heaters etc only become suitable with triacs as the switch

How to Generate Electricity from Sea Water Simple Experimental Project

Just like wind and sun, sea is another example of massiveness and a potential raw energy source that may be harnessed for acquiring electrical power. Yes, just as solar or wind power, sea surfs can also be effectively dimensioned and converted for generating electricity. How? We�ll learn in this article through one simple experimental set up.Probably there would be hardly anybody who might not

4 Bit Analogue to Digital Converter

The operation of the converter is based on the weighted adding and transferring of the analogue input levels and the digital output levels. It consists of comparators and resistors. In theory, the number of bits is unlimited, but each bit needs a comparator and several coupling resistors. The diagram shows a 4-bit version. The value of the resistors must meet the following criteria:R1:R2 = 1:2;R3
