Make: electronics book, Experiment number #11

Make: electronics book, Experiment number #11

Putting it all together.

In the first part of this experiment, we put together a programmable transistor with a capacitor to try and simulate the result of a previous experiment in which we used a switch.

The circuit was easy enough and the explanation pretty clear.














The result was a blinking LED.


The difference with the 2N6027 transistor compared to the 2N2222 that we used in the previous experiment is that the 2N2222 amplify the amount of current it gets in the gate, and the 2N6027 use the gate as a information to know how at what amount of current it should let the signal through.

as in:
If we put 2 volts  in the base, the anode must receive at least 2volts before the transistor let the current through.

Anyhow, this was pretty straightforward.

Here is the final result:
