i have constructed this inverter to charge my EV i have 12V DC from solar pannels and i need to recharge my 120V battery pack so i needed an voltage inverter after buying one i have tested it and it blowed in 2 hours so i started building one myself using the ferite transformer and rewired it for my use is very sinple and can be made for every one needs can output any AC voltage with proper wiring i use it only with 110v for my needs but in the diagram i had added another wiring for 110 and 120V as you can see it powers an 200W halogen lamp for testing in test i have used only 2 FETS but they are too hot so i have added another 2 for more power if you use only 250W you can use only 2 with propper cooling if you want more that 500W you need to add another 2 for every 250W of power and use an bigger transformer from my findings this inverter has around 75% performance Be carefull at output you have dangerous voltage Step 1: The built inverter for 250W   A s i said this one gets hotte...

The auto sound systems of today are much more involved and complicated than the simple car stereo and speakers of years long past. Today's sound systems have all kinds of bells and whistles that many us could have only imagined during our younger years. In fact, it is quite possible that many of us did imagine these and those imaginings are how they came to be. One thing you need to do before you even begin to put the auto sound system of your dreams together is learn what kinds of components exist, how they work together, and which ones you really think you need as part of your auto sound system and which components you honestly feel you can live without. Life is about compromise and most of us will readily admit that we are quite unlikely to ever use all the bells, whistles, and upgrades that are made available to us within our lifetimes. I don't know about you, but my cell phone has features I've never even gotten around to learning how to use. I know I can use them and...
