Great simple explanation. Thanks for the video.

Great video. I was just a bit lost until I read your answer to yamandudacosta. The Relay action is just a representation of what occurs inside the gate. Being an electrician I got focused on seperating it all when actually they weren't. Whoops! I get it though.Thanks.

@BenBen5501 I used a relay since it was the simplest way I could think of inverting the input. Glad to be a help.

[gambart2002]

Awesome. Thanks.

Thanks for tut - really helped me for my exam tomorrow

How could one make NOT gate electrically (not electronically) without using relays?

Is it possible.

I mean, withou short circuiting and firing evreything.

[Ongytenes]

My first thought was to tell you of how a person can use a transistor to create one, but then I read your comment again and saw you specified "not electronically". I used a relay as a means to make it easier for a person to visually grasp the concept. Off hand I couldn't think a simple way to replace the relay, but ways that tend to be more complex electrical-mechanical. Like solenoids and pneumatics to operate a contact. If you think of a way please share it with us.

[yamandudacosta]

@Ongytenes Thanks. I found that I could invert an input variable using a normaly closed switch also. But this is limited to negate variables. If want to negate an expression maybe could do it draining the current to the ground when circiut is close but its dangerous.

@Ongytenes How can you do it with a Transistor?

[Ongytenes]

@CaptainBumsgewitter

See my video reply: ANSWER: NOT Gate using a NPN Transistor.

hahaha light buub

Excellent video for someone just beginning in logic circuits, namely me. Thanks for the video.

[Ongytenes]

Thank you. I actually write programs and then record them in operation as a video to upload. I do this because I wasn't satisfied with any presentation software I saw. So I write my own interactive programs to my own satisfaction.
