HOW TO MAKE PAPER TRANSISTOR
List of material need
1. Paper (any book are note paper )
2. Pencil (any one )
3. LED (20 mA small LED)
4. Wire single strand
5. Sticking tape
6. Battery (6 volt 4.5ah or 12 volt 7ah for best result )

Step 2
Step; 2
By using an pencil draw a transistor shape on paper you have (note: make it as small as possible and mean time big enough to wire to be pleased on it )

Step
draw a outer line using pencil

Step 3
By using your pencil try to fill the space with multiple layer of pencil cote many as you can until you get reflection on paper (note : use blunt tip other vise paper may damage )

Step 4
Above image shows that (E, B, C) emitter base collector by using the sticking tape please a negative terminal from a battery to an emitter terminal of paper transistor at bottom side

Step 5
Taka a LED and please a cathode at collector terminal stick with tape (make sure it properly touching the paper) and anode terminal of an LED to an positive end of a battery (NOTE: by this time LED will glow other vise check the connection

Step 6
And using a single strand wire make another positive terminal extension and please on the base terminal of an paper transistor (note : do not stick it )
By this base supply the LED will turn off (NOTE: because the negative supply traveling trough the emitter to collector terminal is intercepted so at the base terminal the positive potential is equal or greater than the negative potential ( + => - ) so the LED turns off )
