USB Hack

USB Powered Keyboard Lighting


Bored at home?  Left with unused or non-working USB cable? 

Here’s a small thing u could do this Christmas...

Things Needed :

USB Cable                                - 1 Nos 


Straws                                       - 2 Nos
                                                        


Single stranded wire                 - 1 meter
                                                 


Switch                                       -1 Nos
                                                  


Theory :

Firstly before going into the on hands experiment, let us first know what USB is

·        USB stands for Universal Serial Bus
·        It has four thin different colored wires inside it viz. Red , Black , White and Green
·        Each of these colors indicate a specific purpose , as we know that an USB is essentially used to transfer the data , it should essentially contain a Data transmitting & a Data reception wire these wires are colored white and green respectively.
·        And any port or any machine for that matter, needs power to operate/function
For this purpose the two other wires are used. The red wire is used to input the USB with 5 Volts DC, and the black being the ground wire.
·        The general block diagram of the USB is given below.






Block Diagram :




Procedure :
·         Cut the USB wire about 5 cms away from the Jack and unstrap the wire.
·      Connect all the components as shown in the block diagram
·        Use hot glue or solder the joints of the wire to the switch and the led’s
·        Put the led’s inside the straw and wire them from the other end of the straw as shown below, this makes our led’s look like street lamps.
·        Once you’re done , color the straws to give them the best look
·        Now connect the USB end to the port and using the switch control your led’s.
·       This is most used at late nights when you’ve got to work and someone’s sleeping in the room and you’re forced to shut down the lamps.
