Thanks Rick for a Excellent Explanation of the 555 Timer!! Our little Friend has been around since 1970 ( Designed by Hans Camerzind) and is still used in Countless applications!! I designed a SCR Tester as well as a Remote Control Tester using this little fellow. thanks from 321reh

Nice explanation. I am using this IC in an audio-modulated flyback transformer driver.

Hi Rick, I can remember working for a company that was just about to embark on its first solid state project, the team leader went out and brought a 555 and a 9volt battery. You realise that you now have your lifetimes work cut out don’t you, building the seemingly limitless assortment off 555 timer circuits. It’s such a versatile little chip, well done on another nice video. By the way, if you start on the 741 op-amp that should take care of the afterlife as well.

Kind Regards ... Andy

Hey Andy,

Thats just what I need, two lifetimes work projects, lol. That 555 is amazing versatile and so useful too, and I think it is great that it has been around for many years and if you have done anything at all with chips, you know about the 555. Also the 741. Between those two chips, it would be impossible to run out of stuff to build, and their cheap too.

Regards

Rick

Good lesson on the 555. Seems like I learn something new with every explanation of the versatile old workhorse chip. There was a cool international 555 project contest last march (contestant had only three weeks to design and build and document their entries). Some of the creative designs were fascinating. Google 555 contest.

Thanks Shoetiefly

And thanks for the 555 contest information.

I also found this video very helpful, especially the explanation of the inner workings of the 555. Thank you. Sub'd

Good vid, Rick, but I have no idea what I'd do with a 555 timer.

I just watched a vid where a young fellow used a 555 timer to build a small am radio. I guess he was using it as an oscillator.

Thanks.

Hey John,

The 555 is a good chip for the beginner. It is cheap, not to complicated, and very useful.

Regards,

Rick

Great video ( : Especially as I have recently been experimenting with 555 timers, namely using them to drive a MOSFET that controls a high voltage transformer (video on my channel) but it is nice to learn what actually happens inside of the chip.

Thanks Alex1M6

[myworldismine72]

Perfect video exactly what i wan thanks

[AllAmericanFiveRadio]

Thanks myworldismine72

Your welcome. Looks like there are others interest too.

[ElectricSparq]

Good stuff.Thanks again for the free training.

[AllAmericanFiveRadio]

Thanks ElectricSparq

All 3 resistors are 5K. On the schematic, it's R7 = 5K

[AllAmericanFiveRadio]

Thanks eirpcalc

Yep, I misread that one, going from the drawing above to that one. Theres two labeled that way, nice convention. Well, I know you looked at it.

[AllAmericanFiveRadio]

@eirpcalc

R10 is screwed up. Must have been the application they used, doing auto spacing.

[maahal]

Very nice vid :)

That's the Best explanation of the 555 I ever heard..Added to My Favorites & Playlists..Thank you for sharing.. All so Thank you for the PDF ..Tec

Thanks tectalabyss

[dennisbauer65]

Thank you allamericanfiveradio, very informative.

i not long read the history of the 555 it was great.

your videos are the best thanks mate.

[AllAmericanFiveRadio]

Thanks dennisbauer65

Thanks raddios2

Thanks ae4se

Now this 555 or something similar are incorporated in other chips plus much more. Yet it is still used today and is great for the beginner. It works and it is cheap, and lots of circuits for it. Radio Shack did have some great books and they do have some project books today.

I'm an analog kind of guy. Stuff like this 555 chip amazes me.

[AllAmericanFiveRadio]

Thanks Barnekkid

[barn5923]

Your videos are very educational I enjoy them all.
