I’m an engineering student and these videos are more helpful then my actual lectures
same here
@@setrikaz9636 That's great and I'm so thankful for GreatScott's videos. The question is why are his 6 minute videos more helpful to us then the paid lectures we've sat through in college?🤔
@@Paradox3627505 school, college, university and all other of these things teach you many things, but usually those things you learned are outdated as hell and wont help you in real life situations.
I mean like the most mOdErN thing that schools may teach you is Arduino, which is a technology from 10 years ago, they dont teach you something to use in a year or so, they teach you what they already used in many years back
You won't imagine how that this video came perfectly on time for me, thank you
Thanks a lot! Also the "freshen up an old signal" hint is valuable. Just wanted to leave a thank you here, since you helped me also a lot and I watched a lot of your videos.
Thanks for the support :-)
You are one of the few channels that actually uses the paid promotion feature. Thanks for doing this.
Lovely refresher course from my schools days too long ago to remember when. I gotta check out that PCB place.
Thanks for making a video at this topic! I red an article on it 2 days ago but had no clue how it works. Keep the niveaful content up 👍
Thanks for the feedback :-)
Thanks a lot. Your videos help a lot for homework assignments, lab reports and lab work. You're beyond awesome.
This was a very good explanation of a shmitt trigger. Thank you.
WOW! Schmitt triggers are awesome! thanks for the video.
3:02 - That diagram told me everything. THANK you!
Thanks for making a video on schmitt trigger, two days after i gave up on my project involving these xP
This is not at all what I thought a schimitt trigger was. Thank you for the information. I need some of these now.
Very interesting. Thank you.
BTW, I like that ad. It reminds me I want to get into pcb design again and try to get my first pcb design printed.
Thanks
Thank you Sir you make the best tutorials!!!!!!!!!!!!!
i did enjoy the video, very good explained thanks!
You can also use a 555 timer IC as a schimitt trigger
what can't you use it for?
XD
555 also contains opamp
Luiz Fernando you can also use a 555 for combing your hair and cleaning the dirt from under your fingernails... without even a battery! They are very versatile, if a bit old-school.
Ray, I made an extremely loud noise with one the other day without a battery. I had dropped one on the floor. It landed legs up. I was barefoot and found the chip. The noise generated scared the cat out of the shop.
I was just desingning a project on software - hardware and had to take in count those problems, I already knew all you said there and it was very crazy that you uploaded it the same time I was working with that haahha, had to make the subtitles on spanish!
Enjoy the subtitles!, thanks for all your work
Glad you liked it :-)
cool video! I use hex inverting schmitt triggers for my synthesizers / electrical instruments
I didn't understand anything in this video... Loved it!
The high/low values for the inputs in the datasheet of a microcontroller (or pretty much any digital input pin of any logic circuit) are not equivalent to those of a schmitt trigger. They tell you what will definitely be seen as high or low voltage, but the outcome for everything in between is undefined.
superdau good point. The mistake slipped past me, thanks for the reminder.
great video and keep up the good work, i was wandering if you were planing to make a video on the hall effect sensor ;)
i love your videos you are best electronic channel :)
Great video; as always! Keep on with such great videos!
As a suggestion a LoRa video with be great to see in the near future :)
Awesome tutorial
Great video
Love your videos!
Another awesome video 👍
Perfect as always :)
Ya ....he's back with pure electronics.....
Really, really nice! 😊
Hi Great Scott
Great job.
great video
I wish my professors at university was at least half that good as you at teaching electronics.
I like your work
Wooaa, kinda over my pay grade!
... Didn't quite match my query towards a simple explanation for the incorporation of the Schmitt Trigger into a touch probe sensor circuit.
Very well done though. Thank You
I know it's completely off-topic, but I realy like Your handwriting :D
using an op-amp as a comparator can have quit few pitfalls. Some op-amps have protection diodes between the +/- inputs so you can have more than a few 100mV between them and some op-amps invert their output when they hit the rail
You should make a synth. Maybe a simple one from music from out space
Plz do a vid about MOV's metal oxide varistors, I can't find much solid info on them, you seem like a pretty reputable source so your video will probably get first at the top of the search results.
very good
Nice work. Was a long time since I learnt that. Would it work for looking at signals in a noise floor?
Doofenschmitt Trigerrinator?
When i was a kid, something something baloons parents something
How convenient, I just salvaged a Schmitt trigger IC.
Hey I have a question, maybe in the next video you would like to talk about how to connect and handle the gyroscope for ardruino , ;)
I watch your videos just to hear "Let's get started"
This little thingy helped me get rid of 100 lines of code from my Arduino project :D
Sweet!
Yes, if you are using code to debounce your switches.
I'll be using it to debounce some variable resistors (those flexible resistors)
For debouncing and protection and some other details simply use the MAX6816.
Hey, greatt video, could you make make an H-bridge with N Chanel MOSFET logic or standard for controlling DC motors at High currents and you could do a DIY VS BUY if you want, In the internet Theresa is a little information about this.
Can you do a video on electronics diagnostics, like finding a short or a dead component in a circuit board, please ;)
Top Video
Can you use the schmidt trigger for a subwoofer circuit to only let pass the high voltage peaks comming from the bass?
Because i am trying to build one on my own and not copy circuits from the internet.
And keep up the work. Your videos really help:)
Hey! @GreadScott! nice video, please you can talk about the analog multipliers? c: saludos!
Please Publish some Op Amp related tutorials. Thanks for the nice video
very good, many many thanks ;-)
excelente amigo
saludos amigo :D
Can you do video about I2C protocol?
Keep it up
Please make video to explain how to use arduino as usb serial converter
Thanks great scoot
Hey, nice video, are you building your own vesc for the quadcopter or for the longboard? I think it seen your previous videos, am i right?
Do a video about brushless motors and how to control them
Hey Scott,can you make video about DIY electrical guitar and how it work.
Can you make a video about general purpose parts you should always have on hand
Yeah, blissful education.
GreatScott, can you try to use a Schmitt trigger to make a power button? So you would have one button to turn on/off an Arduino or any other device(from 0-3Amperes).
Dig or buy li ion BMS with monitoring and balancing. ??? great video. what does Schmitt think about this?
Make videos on iot projects because they are famous in this tins
You should do more Raspberry Pi (or other single-board computer) projects.
Super
Can you make a video about measuring voltage with arduino
Amazing coincidence! I just ordered a tube of 74HC14’s a week ago for a project to “de-bounce” a set of push buttons on a control panel! Thank you for the great video as always. Trying to learn how to make a custom shape PCB... can anyone help?
James Childs custom shape as in the outline of the fibreglass board itself? The cheapest way is probably a hand held fretsaw. Practice on some scrap cos they're not the easiest things to control neatly..
*Why do you keep saying shipping on JLCPCB is free? Am I doing something wrong? I'm always getting at least 10 dollars shipping with Registered Air Mail.*
Same here
"keep saying"? I did not mention the free shipping in the last videos. If you experience problems with the coupon then contact JLCPCB. That always worked so far.
GreatScott! You did mention it in the video "currently with free shipping" ;)
Island Monkey for your first order only. Probably not for registered air mail though.
Btw, what I hate about PCB manufacturers that price is hard to compare :( They seem to compete with the price of the board, but shipping is always more then the price of small boards. And "surely" there is no easy way to know what will be the total cost anyway for you in advance, so it's hard to compare all of these manufacturers based on the total cost, what people would be interested more (I guess) rather than some "imaginary" price which is never what you have to pay (ie, the "without shipping cost" price). Ok, for JLCPCB , probably shipping is free for the first order, that's true, but I meant in general. I would prefer a fixed price with ALL things included from all manufacturers (for about the same PCB surely) so it's much nicer to check and compare prices then. But I guess this is exactly what they don't want us to be able to do ... ?
@Great Scott, I would like to know where and what you studiet?
thank you for the German reference. Vielen Dank..
on a circuit bord we make on school 3 schimitt trigger's are used to boost a 9 volt battery to 30 volts only using diodes an elecrtrolitic capasitors no external power is used only the 9 volt batery ter is no induktors and transformers on the circuit bord
Would you make a video about bootstrapping in mosfets?
It is on my to do list
video on bootstrapping needed
What is the name of CRO used in this video? This CRO was very precise and advanced
Sir you haven't build a good boom box for a long time. So please make a speaker box using a PAM 8610 class d amplifier
Nice wave generator.
Can you make a video about shift registers?
and most synthes uses them as the thing that creates the tone which gets fed into a binary counter to sequence.
As a male 27 year old, computer nerd and DIY fan I can say 1 thing about your videos: Im 97% lost when watching them xD
Still love them though :D
Can you make a video on how to make a variable speed fan controller for a computer
currently with free shipping?
Please make a video on MOSFET gate drives. IR2110 IC
Is it possible to change the trigger voltage or hysteresis on the sn74hc14?
Can schmitt triggers be used to make active cables, like a 50 foot USB cable?
DIY smart glass??
Can the Schimitt trigger be used to clean noisy gyro on Flight controllers?
when you will make a video on bootstrapping I am waiting for very long...
It is on my to do list
Can use this technique for Low voltage disconnect and reconnect in Battery charging???
Yes.
@greatscott!_can u make a video on different uses of 18650 battery, i have alot of them lying idle
he did alot he made power bank for led strip and for mobile charging
ahmed elwan these are the only two uses that are available on internet, i am looking for something else
look for life hacks on youtube, which always have a design of an improper circuit and will kill the battery real quick
74LS132P confusing me !! 😵😵😭😭 , it's datasheet is also very confusing , i wanna test this ic , but I don't know whether its Nand gate connected before of schmitt trigger or after that ???? By powering ic with 5v I measured its output voltage on its one ( two input Nand-schmitt ) that is 0.9 v on input A and B and 0.3v on its output Y !!!!! , it is ok to test one input schmit trigger for me !!! but ------ " How to test ' two Input schmitt with Nand ' Output With Hysteresis ????? Datasheet shows :// - on Vcc= 5V , VTh+ = 1.5 To 2V max ,, VTh- = 0.6 to 1.1V max !!!!?? and vth+ to vth- = 0.4 to 0.8 type ????? any one tell how to test it using potentiometers and multimeters ?????
I want to make the same thing for low battery cut off and I want hysteresis to be adjustable upto 1V .
How can I achieve that sir?
Hi GS is it possible to make a cell phone jammer ?
Could that be able to work in ESC's???
#35 alredy nice
Please tell me the software you used for schematic design.
Hi scott can you tell me what type of pen do you use?????????????
