Introduction: How to Make Paper Transistor DIY Homemade

Step: 1
Take a paper for any note book
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 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  )

    This might not be a amplifying/junction transistor, but it looks like an switching transistor (although it minimizes the voltage).

    Nice project, I really like it a lot.

    In fact I made my own transistor design based on your awesome (paper) transistor design.

    Take a look at: homemade-transistor.weebly.com .

    this work like a PNP TRANSISTOR but it will not work on a circuit or flashing led only work for LED only LED

    hmm not a transistor

    hmm not a transistor

    Short to ground is what it is
