Hi friends,
im new in instructables and this is my first project in instructables

The circuit is very simple.
what all things you need are;
1. two cool white LEDs
2. One green LED
3. 120Ω resistor
4. some wires
5. a USB male pin

 

Step 1:

Circuits can be done as per the circuit diagram
NOTE:
  The wires from both the ends of a USB pin are its positive and negetive (red and black wires).
Green and White(middle two) are wires for data.don't connect these wires




For Making the Body:
Things required are;

1. flexible pipe ( I detached it from an old table lamp)
2. a reflector ( from an old torch)
3.The thing shown in red marker in the picture (detached from play station 2 dual shock controler)
     (i don't know its name. whatever, im calling it a Wieght holder)

nice one. but isn't the green Led causing glare to the eyes? would best better to put all leds into reflectors.

@ lan01
the chance of failure is very less ,even if it is so, LEDs are very cheap no??

It would be better to use an individual resistor for each LED. With just one resistor, as soon as one LED starts to fail, they will all fail instantly.
