HEY YOU ABOUT TO POST SOMETHING STUPID:
Yes, I know my hands are large/fat. It's because of a heart condition I suffer from called Congestive Heart Failure. Here's a link to some information about CHF: cle.clinic/2TdS2Ux
One of the symptoms is that it causes fluid retention, mostly in the hands, feet/ankles, and face..

I love how you didn't cut out the "what's going on" moments. It shows the reality of breadboard circuits and the fun of figuring it out what the problem was. Ty.
Love the Classic Circuits! Keep them coming - please
Happy Easter! A period for transformation!
Thank you for uploading these "Circuits You Should Know" videos because they are very informative and help me alot. Also, I hope this is a playlist so I can watch all of them!

I think I would have used a comparator rather than an op-amp. They tend to be better behaved when the input go close to rail.
If you are looking for a low component count solution, there are a number of microprocessor reset circuits that can be adapted to function as over or under voltage detectors. They have the advantage of a built in voltage reference.
Nice video 👍
thanks for saving me 10 bucks on some solderstick connectors!
I really enjoy this series, thank you.
Glad you enjoy it!
That is a great circuit.
Thanks Paul.
☮ brother.
Thanks, Paul!
Happy Easter to you as well good Sir
Indeed I enjoyed this video. So I did with all your previous ones, several years by now! This opamp will fit nicely into a cordless drill/screwdriver where I recently swapped out the old NiCd batteries with a new LiIon pack that I build. Looking forward to see your next videos!
Wonderful!
Interesting, thanks for highlighting this simple monitor.
No problem!
Great series! I’m a mechanical engineering student and I am learning tons of useful techniques from this channel for both hobby and for work purposes
Great to hear!
And Ramadan Mubarak ❤
Hello sir, a couple weeks ago I comment on a circuit for an idea to make a 555 on a breadboard. I finally made one and working on a video of it to put on my page. I had a bad IC ! I used a LM393, 74hc8, 74hc02 and a 74hc14. Also a NPN for a discharge and a PNP for a reset. The capacitor a 470uF and had it working by itself in Astable without an external clock! Thanks for your inspiration!
Very cool!
Cool circuit Paul, might be able to use a dual jumper to switch the trace link between over and under voltage monitoring. Happy Easter weekend!
Hello Paul, an other great circuit. it is very cool. Thank you. Happy easter and best wishes from your german friend. all the best for you
Same to you!
I like the TL072. For my application it works better then the LM358
Nice
Thanks
PAUL, in house wiring its Hot, Neutral, Hot and if the neutral gets OPEN this is no longer 120VAC across the load its 240vac. Most the loads are "unbalanced" not the same values across the Hot, Neutral, Hot so when the neutral is an open circuit the unbalanced loads get damaged. How would a comparator circuit be able to detect or sense an OPEN circuit, try making a video lesson about monitoring OPEN circuits
This is for dc
@@learnelectronics I know what about an AC comparator circuit to monitor an AC voltage and if the neutral line is open circuit, what circuit can you build or recommend?
Wire up those LIKES folks. These circuits are awesome and so nostalgic.
Thank you!
@@learnelectronics Thank you for all these great videos! Have an awesome weekend my friend!
Can i use it to detect 230AC?
Because i want my microcontroller to detect the presence of 230AC.
Or is there a better way?
No this is low voltage DC
@learnelectronics can you make an episode about how to detect 230AC so it would not destroy the microcontroller?
I was thinking about using an LED as a main indicator and photoresistor to create a homemade optoisolator.
But I am sure that you know a better way.
It looks to me like both black and red wires of the pot are connected to positive since both + and - of the power rail (rail furthest from the camera) seem to be connected to power via the red clip. Did I miss something?
An illusion, the red clip is only connected to the bottom row of the top right header pins (otherwise, as you say, no worky).
If it was connected like that it wouldnt work
@@learnelectronics Sure. OK, now I notice the white wire on the right which connects both ground rails.
Cool...🥚🥚🥚🥚🥚🥚
hands that look like xraytony
and Happy Eostre to all you Pagans
Stupid question, where is this in comparison to the load?
This is a battery indicator, should be in parallel with the battery
Something is always wrong....😁
But what if I'm Pagan? ..🤣 just kidding
Feel free to drink the blood of a furry forest creature and bark at the moon lol j/k
You obviously don't know that Easter is not a Christian holiday
Easter...Jesus...tomb...risen? What did I miss, hmm?
@@learnelectronics Easter (ISHTAR) the Babylonian god of fertility is what you're missing... Nothing to do with Jesus.
What do eggs and rabbits have to do with Jesus?
Easter as well as Christmas are pagan holidays
