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 […]

This project “The Production of Ceiling Board from Local Raw Materials” was carried out basically using raw materials which was sourced locally. These raw materials are found to be very much in abundance. Some are materials sourced from the ground and others are from agricultural wastes. Three different types of ceiling boards were produced, their difference being in the type of fibre that was used. The fibres used for this different […]

A battery charger is an electrical device employed for charging batteries. These batteries that are usually charged by battery charger are the storage batteries also known as “accumulator” the battery charger changes. The alternating current forms the power line into d.c suitable for charging. When the battery is fully changed, is up to it’s maximum, 12 volt, the charger with automatically cut-off with the help of the contact relay […]

Car battery level monitor indicates the status of the battery just by glowing LED’s. This work explains you how to design battery level indicator. You can use this circuit to check car battery or inverter. So by using this circuit, we can increase the lifetime of battery. The heart of this battery level indicator circuit is LM3914 IC. This IC takes input analog voltage and drives 10 LED’s linearly according to the input analog voltage. […]

Cell phones need electric sources to charge their batteries in order to work, but there are people in developing and third world countries that find it hard to access electric sources. In an attempt to provide an alternative means of charging to those unfortunate areas in third world and developing countries, a solar powered cell phone charging booth is to be designed and constructed in this project. The goal of this project is to cre […]
