My Light Diagram

Attention: This Circuit is using high voltage that is lethal. Please take appropriate precautions Using this circuit you can convert the 12V dc in to the 220V Ac. In this circuit 4047 is use to generate the square wave of 50hz and amplify the current and then amplify the voltage by using the step transformer. How to calculate transformer rating The basic formula is P=VI and between input output of the transformer we have Power input = Power output For example if we want a 220W output at 220V then we need 1A at the output. Then at the input we must have at least 18.3V at 12V because: 12V*18.3 = 220v*1 So you have to wind the step up transformer 12v to 220v but input winding must be capable to bear 20A.

For all photography and video enthusiasts, a macro lens is quite simply a basic necessity. A macro lens is incredibly helpful to produce detailed pictures of tiny objects or options. despite the fact that nearly each photographer or video recorder wants one among these, they're quite expensive and hence not everybody will afford it. Nevertheless, there's the simplest way to create yourself a macro lens. Everything may be achieved by using any lens, 2 plastic bottles, super glue, and duct tape. A photography or video device to that the lens has got to be connected is additionally needed. 1st of all, the neck of a bottle is cut employing a hot knife. Another piece of plastic that's the same as the form of the bottle’s neck is cut out from a special bottle. This plastic section is placed at the lowest. This forms the bottom on that the lens can ought to be placed. The lens are held near the bottle neck using super glue. once holes are created at applicable positions at each en...
