Introduction: How to Make Paper Transistor DIY Homemade
Take a paper for any note book
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 )
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 )
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
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)
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 )
We have a be nice policy.
Please be positive and constructive.
