This is a reply to a question on my presentation of The NOT Gate. In my original presentation I used a relay to demonstrate the properties of the NOT Gate. The question posted was "How you do this with a transistor?"
This video demonstrates how to make a NOT Gate by using a NPN transistor. The GIMP was videoed in real time drawing the schematic with narration.
