This is how a transistor works

July 15, 2015 By Øyvind Nydal Dahl 2 Comments

A transistor in a circuit on a stripboardOn a sunny June day, about one year ago, I was in the country side of Norway.

I was visiting a friend.

He doesn’t know much about electronics, but I tried to teach him how a transistor worked.

We decided to make a video out of it.

So we went to the University where he was studying (he was not studying electronics by the way).

We found a room with a whiteboard, sat up my webcam, and started shooting videos.

I didn’t really promote video much, I just put it on Youtube.

But today I see that it’s been viewed more than 20000 times and has lots of comments.

You can find the video here:

…and feel free to join the discussion!

In my eBook “Getting Started With Electronics” I explain both the transistor and other components in an easy way.

And you will learn to build things like touch-sensors and sirens.

And lots of other things.

Keep on Soldering!

    The circuit is indeed the building block to creating complex electronic gadgets. Therefore, if you can teach someone how to build a circuit, not only will they be able to follow directions to make a siren and touch sensor, chances are they would be able to innovate on the basic framework to create new and exciting things!

    We too have a post about simple Capacitor which can be made with a small piece of wire. More like a 5pf capacitor which is used in radio.
