How to build a Solar Laptop Charger for Under $100



Build a DIY Solar charger that supplies AC power from a solar panel for under $100. This is a small “micro grid” solar system that can solar charge a laptop, rechargeable tool batteries and much more. It uses 4 basic parts. A solar panel, a solar charge controller, a battery and a small AC inverter. This system is made small for solar portability. You can scale it up for your needs. Please leave suggestions and comments so other viewers can learn how to build a small off-grid solar system themselves. This is a great little weekend project.

Homemade 12V to 48V DC-DC Converter Battery Charger for Electric Scooter/Bike



This is a PC board I made so I can charge a 48V seal lead acid battery from any 12VDC source. This design is simple and uses an off-the-shelf audio crossover coil. It charges my battery from a 12V source that gets switched on once the sun goes down. In the morning my batteries are ready to go and it didn’t cost me anything. Energy from the sun. However I can use with and 12V source that can provide 2-3 amps of power. There is a special circuit that will stop the SMPS once the battery level low around 11 volts. Next day the sun comes up and charges the 12V battery.

How to Build an Electric Fence

How to build electric fence requires the use of an electric fencer to generate and send electric shock down the line. It is sometimes the only resort to teach a bad fence crawling animal to respect a fence.

The main thing to remember is the wire must not have a path to ground. If the wire does connect to the ground the electricity will then enter the ground and not continue down the line.

Most of the time it is only necessary to have one “hot” wire on a fence animals will learn very quickly and avoid the fence.

How to build electric fence is basic, you start by choosing the right post; wood posts can be used but are harder to keep the wire insulated. You can buy special posts that you can push in with your foot that have an insulated ring that the wire in held in.

Once the posts placed, simply string out the wire and attach to the posts. Use a wire tightener at the end to keep tension on the line. Drive a ground rod beside your electric fencer, one wire from the fencer goes to the ground rod and the other goes to the wire on the fence.

Most fencers allow you to either plug 110 current (regular household plug-in) or have 12 volt attachment. If you are in reach of electricity run a cord to plug in the fencer. If you are not near power you can use a 12 volt car battery and use solar power or other means to recharge the battery.

Electric fencing is economical and fast to build, I hope you learned the basics of how to build electric fence.

A Simple Homemade Solar Power Generator – Build Cheap DIY Solar Powered Generators Plan

Use of renewable energy is now being harnessed by many people as calls for environmental protection and natural resources conservation are being the talk of the town. Consumers also are now finding ways and means not only to help mother nature but also save and spare money from the cost of daily living which is now becoming higher and higher. It is good to know on how to build cheap diy homemade solar powered generator.

Solar energy generator are basically like batteries which stores energy from the sun and keeps this power stocked up until usage for such is needed to run appliances or electrically run apparatuses.

Building a solar energy generator is initially costly and spending out a reasonable amount of cash is the only way to go. However return on investment is very good and feasible since the large initial amount is sheled out only once (during installation except of course for probably maintenance and repair), however use of such is electricity and power is on the daily basis. Savings must be huge as the increasing price of electricity is cut into half or much better zero as dependence on using the solar energy generator becomes a hundred percent. Return of investment may be attained in a couple of years or much shorter should price of electricity continue to soar.

To start making a solar energy generator purchase of solar panels is needed or building one's own can also be accomplished (choosing which option one must take will depend on the financial situation and the capacity of the person to make such from ordinary items). If buying of a solar panel is the chosen selection by the user it is suggested to buy a solar panel whose rating is 12 volts. Buy or acquire also a dc meter, an inverter (to convert dc to ac which is needed by some electronic devices) and deep cycle batteries (choose batteries which are dependable and are capable to handle long and continuous usage). Building a suitable battery box may also be required to keep the equipment from being destroyed and for curious people from getting hurt. Insulation is also proposed for purposes of safety, efficiency and quality output of the generated electricity.

To start off making a solar energy generator the meter as well as the input device is attached to the battery box and after this all these items are now part of the box, together with the DC meter and the inverter each are connected to the solar panel .

This type of solar generator is able to run small household appliances such as electrical fan, personal computer, radio and television however this is dependent on the quality of charge it receives from the sun's rays. The capacity of the solar energy generation is dependent on how much it was able to get and receive from the sun. Know you have a better idea on building a cheap diy homemade solar powered generator.
