       Magnetic Generator – Build Your Own dont turn your brain off Produce Your Own Electricity It’s hard not to have heard about the magnetic generator over the last couple of years. There has been a lot of excitement surrounding this incredible invention. Some people have called it a scam while others have stated that it has totally eradicated their electricity bill. The truth is that there is a lot of misconceptions about the magnetic generator but at the end of the day, it can power your whole house. The Biggest Misconception About The Magnetic Generator Lots of people are quick to call the  magnetic generator  a scam because as you may or may not know it is impossible to generate electricity using just the power of magnetism alone. However these people who can’t wait to say that it’s impossible haven’t even seen any of the magnetic power generator plans that are available. The one thing that all these generators have in common is that they require a power

LM 317 Here is a simple but effective battery charger circuit using IC LM 317.The circuit can be used to charge 12Vlead acid batteries.The circuit is very simple and can be easily assembled on a general purpose PCB. The heart of the circuit is IC LM 317 ,which is an adjustable voltage regulator IC.The pin 1 of the IC is the control pin which is used to control the charging voltage.The pin 2 is the output pin at which the charging voltage appears.The pin 3 is the input pin to which the regulated DC supply is given. The charging voltage and current is controlled by the Transistor Q1,resistor R1 and POT R5.when the battery is first connected to the charging terminals ,the current through R1 increases.This in turn increases the current and voltage from LM 317.When the battery is fully charged the charger reduces the charging current and the battery will be charged in the trickle charging mode.  This image downer not another image above
