Hi Paul, love your vids as you talk in easy to understand language that helps me greatly as a very late learner to electronics. Please keep them coming and very interested in your anti dog barking project as I’m in desperate need of one! Keep well and best wishes from Perth, Western Australia
Tying pins 2 and 6 together ensures that they will both be referenced to the same voltage to ensure that they are never in the same state at the same time. Keeps the circuit stable.
Can you make a video to show how to make a comparator from transistors and diodes like in the 555 internal curcuit... the only curcuit that I don't understand inside of the 555 timer is the comparator stage and can't find info on line.. Could you please explain how to make and how a diode/transistor comparator works... Thanks...
Is it possible to make a custom 555 timer by a Dual comparator lm393 act as 2/3 and 1/3 comparators One nand gate sr flipflop using ic7400 2 bjts one npn and pnp And a output driver circuit And 3x 5kohm resistor??
Always good to go over these classics and refresh the old brains.
This is a unique and really quite good intro to the 555 timer.
That was a good demonstration! Thanks!
This is by far the best explanation of this little diamond.

Perth! I've been to Perth. Friendliest people I met anywhere while I was in the Navy.
Awesome!The 555 is one of my favs.Great video!💪🏽
Great video Paul. I’m looking forward to learning more about this gem.
Back to basics.. I love it.....The 555
Through explanation, thank you.

Enjoy short and to the point on the basics that can build upon in follow-up sessions. Way to many complicated 555 videos posted. Good job; thanks.
You could set it up as a speaker protection circuit for DC offset exceeds a certain threshold. ADCOM likes to use the 555 Timer for that purpose.
Great! Please expand on this. Like: Why connecting 6 to2?

Grabbing the oscilloscope and playing with the control voltage pin could make a good video on a slow day.

And a output driver circuit
And 3x 5kohm resistor??
You need almost 70 transistors. Have a look at the Evil Mad Scientist Three Fives kit. It is an analog 555.
Basically you are using the 555 as a relay in this demonstration
Ah the 555 the most used chip in the world!
