How to Handle a Huge Home Improvement Project

When it comes to home improvement projects, most people envision a new coat of paint. However, when you want to replace the staircase, put up a new patio and combine three rooms into one, home improvement financing seems all but unavoidable.

Mortgages and equities are part of house improvement financing. These are known as secured loans, for which collateral, usually in the form of your property, is required. Keeping up regular repayment is important, and the home owner who neglects these risks losing his home. There are also unsecured loans. The amount for unsecured loans is lower than that for secured loans, but the interest rate charged is often much higher.

It is possible to renew your home without resorting to a bank loan by carrying out the house improvement in stages. Complete each stage of the project in the order of its importance. Spending only what you can afford allows you to pace your home development to what suits you best. It may take longer, but at least you do not have to service a bank loan.

Last, but not least, you can always carry out your projects on your own. It's impossible to avoid hiring people entirely but you will not need home improvement financing to pay the electrician. Attending workshops and asking questions at stores is a good way to learn as you go. As with carrying out the renovation in stages, home projects carried out this way will take more time, but you will end up saving a lot more on the expenses incurred.

You should always keep in mind that any home improvement activity you carry out has one main objective – to improve the quality of life of everyone who lives under that roof. Never get talked into anything more extravagant than what you planned; learn to trust your gut.


Project 12: How to make a Portable Power Bank or Mobile Charger.

In here i describe how one can make a Portable Power Bank or Mobile charger using,
1. LM7805
2. Female USB Connector
3. Switch
4. 9V Battery & Battery holder
5. PCB Board or ferro Board

This is very cheap you required very less money.

Green RV Project. Part 4. Charging the RV Battery System

Charge your RV batteries the right way and they’ll last for years.

Many RVers complain that they’re batteries don’t last long enough, or that they fail and have to be replaced too quickly. This is almost always because of poor battery charging and maintenance.

In this episode of the Green RV Project, we talk about the importance of proper multi-stage battery charging when connected to electrical hookups to optimize the effectiveness of your battery bank and make it last a long time. Specifically we discuss the Xantrex TRUEcharge2, the benefits of the system, and do a brief review of the installation of the unit.

We discuss:

-The stages of charging

-Why you should have a multi-stage charger instead of the converter your RV may have come with

-Have the right charger for the type of batteries you have.

The Xantrex TRUEcharge2 can be found on

It turns out that I have more battery chargers than sense, so I built this monstrosity.


Rotating Solar Inverter Project using Microcontroller 50W

This video shows the demonstration of “Solar Inverter Project using Microcontroller”. This system is mainly designed for charging 50 Watt Inverter using solar energy. Due to the many benefits of using solar energy, many institutions are opting to make use of solar energy.

For more information on this project, visit

This system uses sun tracking solar panel which helps to charge the inverter. The inverter is used in case of power cut. The inverter is an electronic device which converts DC to AC. In the presence of electricity, inverter gets charged. These types of solar panel ensures that maximum amount of solar energy is captured into the panel by continuously keeping the panel surface perpendicular to rays of the sun, in other words by facing towards the sun. This system is powered by ATmega 328 microcontroller, it includes a transformer, MOSFET switch, DC inverter,12 V battery, 50W solar panel and charger. Solar energy helps to charge the battery by a natural source of energy. As we switch on the loads, the battery chargers the inverter and it gets converted from DC to AC, then the setup transformer increases the voltage required to run the device. MOSFET is a transistor which regulates the voltage and then it provides powers to the load. Our system successfully powers the AC load using a sun tracking solar panel.

Overheating Battery Issues Stall Chrysler Hybrid Project

As the demand for hybrid vehicles grows, Chrysler has been forced to momentarily shelve their hybrid testing. Tests found the batteries overheated in some of the pickup trucks. 109 truck models and 23 minivan models with plug-in hybrid technology are no longer currently testing.

It seemed the Dodge Ram 1500 pickup trucks were delayed to damage due to their prototype batteries. There are no reported fires or injuries to operators as a result of the damage. Chrysler is testing a lithium powered battery since the third quarter of 2011. The project was expected to run through 2014, but no plans have been made to extend the testing.

This testing is partially funded by the United States Department of Energy to the tune of $ 58 million. Chrysler makes up for the rest of the funding with $ 65.2 million. A majority of the money was meant to fund the pickup truck testing, which was expected to cost $ 97.4 million. The reminder of the fund was meant for the minivan testing that was expected to cost $ 25.8 million.

The project testing was spread between 16 municipalities and utility companies. That spread the testing between 20 states. The batteries themselves were supplied from a Canadian company called Electrovaya, which specializes in lithium battery development and manufacturing. It even released its own electric car run on the battery that can go for 120 miles on one charge.

Despite the suspension of the truck and minivan hybrid project, Chrysler is moving ahead in development of the company's own battery. A representative has called their vision a "superior battery" to what they were implementing before. This time the company will create a different chemical makeup of the battery to prevent the overheating problem.

So far, the vehicles tested as part of the program have racked up 1.3 million miles equivalent. Minivans have recorded as high as 55 miles per gallon while the trucks have gained as much as 37.4 miles per gallon. Current hybrid minivans average about 28 miles to the gallon and trucks average about 23 miles per gallon.

Part of the testing was not just to increase the mileage of every gallon, but to create reverse power flow. This is where the battery then sends power to the electric grid. In the future, the powerful vehicle batteries could have the backup for home appliances during power outages. Chrysler hopes to have the first to release a vehicle with electric grid connectivity.


Maintenance Shop project part 1

We recently added another rack to our shop today so that all of our power tools and battery chargers were in one place instead of all spread out throughout the shop. This is the beginning stages and a mess of a shop. Also added a half inch metal conduit and double USB receptacle next to the rack so that we can charge our phones and tablets. We have wood to go on the shelves they we are going to paint and I have four more shelves coming for this rack so that we can have all the power tools in the shop of different brands and one area. Stay tuned for part two
