Design And Construction Of An Automatic Change-Over Switch With Generator Cut Off And Starter

This project traffic light is design for the safety ness of vehicles our the road. It is a very destroy loop and sensor that which coordinate the system when the driver encounter long sharing of green light. The traffic light is consist of two more chamber or circuit red and green or amber/yellow which the red high gives the sign of stop the green is for free movement on the that is a junction or about.

The purpose this text is to present at a primary and intermediate level a comprehensive over view of the construction principles and indeed the operation of a power amplifier with 100w as the output power. The history and importance of electronic as a unique braches of science cannot be over emphasized electronic as its history might have it is divide into sections the first began with the invention of the vacuum tube the second occupy […]

This design implementation of this electronic sequential sign post display employs the use of some specialized components. This section of the project introduces the reader to the different section of the project and the components that makes them up. Emphasis are laid on describing the behaviour and operational system of the components as related to the project modeling, analysis, design and implementation of an ELECTRONIC SIGN POST, […]

This work is titled construction and fabrication of an ice block making machine. Ice block making machine revolves around the concept of refrigeration. The concept of refrigeration revolves around the reverse Carnot cycle. This is a cycle involving isentropic expansion (at the throttling valve), isothermal expansion (at the evaporator), isentropic compression (at the compressor) and isothermal compressor ( at the condenser) Compression […]

The 200W solar system was determined by load assessment, solar panel number determination, battery requirement and then inverter sizing. A complete solar panel rated at 200w was however purchased, together with 2 no. 150A solar battery, 1500W inverter and also 10A charge controller. These were assembled together with necessary protective gadgets like cut out switches; to give the 200W expected. The solar panel was mounted outside the b […]

The early transmitter for radio broadcasting is so big and bulky that they do occupy numerous spaces. The circuitries are mainly designed with valves, which are big in sizes. With the advent of semiconductor materials such as transistors electronic equipment are now becoming miniaturized such that small transmitters are now becoming handy and compact. In line with this we choose to design a complete radio broadcasting equipment tat is […]
