Project- 2: How to make a USB light by using a unsupported USB cable.

PROJECT : 2

How to make a USB light by using a unsupported USB cable

           
       
               In here i describe how a USB light can make from simply 2 LED and a unsupported USB.
Just you have to cut the USB and select red and black wire and connect a LED to this. when you connect this USB to your PC or mobile charger or OTG cable then light is on.

From USB you get around 3 to 5 V and in red and black wire you get that so i just use that and lights on those LED.

Project-1:How to make a 9VDC source from 220 V AC system by using bridge rectifier circuit.

Project-1:

    How to make a 9VDC source from 220 V AC system by using bridge rectifier circuit. 

              A bridge rectifier is an arrangement of four or more diodes in a bridge circuit configuration which provides the same output polarity for either input polarity. It is used for converting an alternating current (AC) input into a direct current (DC) output. A bridge rectifier provides full-wave rectification from a two-wire AC input, therefore resulting in lower weight and cost.

     A bridge rectifier circuit given here,
                                                     

BRIDGE RECTIFIER

LM 7809 IC description means where input and where output you connect given in the figure below,

In this video i describe how one can make a 9 VDC source from our domestic 220 VAC source.I use basically a transformer,a bridge rectifier circuit and a voltage regulator.

PROJECT- 1

You can buy transformer from the side mention below,

What's inside a magnetic ballast which is used to start tube light

What's  inside a magnetic ballast which is used to start tube light

Magnetic Ballast

           An electrical ballast is a device intended to limit the amount of current in an electric circuit. A familiar and widely used example is the inductive ballast used in alternating current fluorescent lamps, to limit the current through the tube, which would otherwise rise to destructive levels due to the negative differential resistance artifact in the tube's voltage-current characteristic.

     In below i give you a link where you can get information about types of magnetic ballast.

What's inside an Electrical Starter use to start tube light

What's inside an Electrical Starter use to start tube light

           Inside a electrical starter there is basically two things are present one is capacitor another is a bi-metallic strep. This bi-metallic strip is normally in closed condition but when current passes through it due to heat loss this strip is going to increase it's length, and as a result the circuit is going to disconnected.

Check this video

Actually starter works with choke coil, to release photon from tube light it is required to ionized the tube gas and for starting stage it requires high voltage, now concept E= L*di/dt when rate of change of current is high then emf will be high, so starter works very fast and when the voltage reaches at required limit to start the tube then starter out from circuit of tube light electrically.

 

 

My next video will describe the inner parts of a electrical choke or ballast.
