This is very informative intructable post

Most of us don't know the secret behind the simple NOT GATE

NOT GATE is nothing but a single transistor

You can make easily in 2 minutes also you can verify the out put .....

    While this circuit does invert the signal in your simulation, it is not actually a NOT gate. A correct NOT gate would be actively driven. For a 5V TTL circuit: if the input is at least 2V, the output is pulled high (5V); but if the input goes below 0.8V, the output is pulled low (0V).

    yes you right

    low level is considered here 0.7 - 0.8 volt

    Not exactly. For TTL, you are right. However, for DTL, you are incorrect--passive pull up is used.

    Well... I think NOT. Just a video without any ohters materials( schema/parts/tools/values) if you want to win videos view this isn't your site. Please, post images with more info and some text. THIS is the idea of Instructbles, not a site to win YT views

    OK bro
    In all my upcoming instructables I will share each and every things required to make a featured and good instructables

    thanks for your advice
