The coolest diy Oscope on YT.
Great job....
Thank you =)
I love circuits like this that use chips in cool ways they were never really designed for. I hate to think of the pain that would come from trying to use this for any practical measurements though.
Really cool implementations of the 3 ic's, great job and the write-up is a nice touch
Thanks to you for appreciating my work :)

How did you connect the iPhone frequency to the circuit. ? Pls tell me
Amazing!!
Audio output goes to 555 and Controll the LEDs with 4017 and
A 4093 with one resistor and one capacitor would replace the 555 and all its circuit and do the job just as well. And that leaves you with 3 gates to make a trigger circuit with.
Very interesting alternative! Thank you so much:)
Bravo Stefano. Bel lavoro. Grazie tanto per gli tuoi disegni e spiegazione. God[Bible] Bless.
Grazie a te per apprezzare il mio lavoro =)
That's an awesome circuit, only using standard ICs 👏 😀 👍
Thanks so much Karl 😁
Excelente proyecto.
Gracias:)
nice job
What if i want to use an screen rather than LEDs so how can i make the connection
At this circuit you can not connect an LCD, it is designed to use a led matrix as a screen
Caspita, mi fai venire in mente quello che avevo realizzato io nel 1991... un po più sofisticato.. ingresso segnale trattato, sincronismo, etc. e funzionava veramente bene
L'elettronica analogica è troppo bella :)
HI , good job , but i am not sure how leds are connected ; all cathodes are implanted in hole pad and soldered betwen them ? while anode along tracks, are cutted..Is that right ? Thanks
Hi, Yes that's right, since I made this PCB in house, a few years ago (in 2011) I wasn't able to make a double layer PCB.
Am I right in thinking that this is not possible on a simple breadboard by virtue of the layout of the grid of connected conductors? (Meaning you couldn't wire the LED matrix on a breadboard right?)
Yes , to simplify things should realize a matrix of LEDs on stripboard and assemble the rest of the circuit on breadboard.
@@Stefano91ste ok thanks!
Finaling i can build up
An osiliscope.
Nice one sir
Thank you :)
Is it possible to use this oscilloscope for square wave signal
?
Hi, Unfortunately no, it wouldn't be able to view it
This is the result of the good logical thinking, nice.
Awesome!
Thank you :)
I love your videos! I would like to build this oscilloscope too, but I need to know what the CD4017 is since where I would get it from, there are three different variants that are: flip flop, logic counters/dividers, and one from the 4000 series. Can you help me with this please?
Hi, sorry for the long waiting time for my reply! CD4017 is a CMOS counter / divider IC and you can buy from here: www.aliexpress.com/item/1005002302665931.html (select CD4017BE DIP16) - You can also find its datasheet in my datascheet archive which I have made available: drive.google.com/drive/folders/1rfkyYgDA8GO9ass8A4s5E32tbQjO2B2d
@@Stefano91ste Thanks!
Hola sabes cómo se pone a trabajar un servo motor con la CNC shield y dos motores paso a paso?
Hola, necesitas un microcontrolador dedicado
Wow amazing project
Thank you!
@@Stefano91ste you are welcome
Nice!!!
Thank you:)
interesting videos I already subscribed you channel
Awesome work - cool!
Thanks you !!!
Oooh my gooood this is what we call invention i have this old big osciloscope in my lab at college
Same as this 😂
Una consulta la entrada de la señal se hace con un Jack o con que componente de antemano muchas gracias
Hola, con un Jack
@@Stefano91ste Mil disculpas que lo moleste señor Stefano pero le cuento que armamos el circuito como tal y el circuito funciona pero no llega a detectar la señal que le ponemos de entrada, estamos utilizando una aplicación Android esto influye o se tiene que utilizar un iPhone para que el circuito funcione o donde cree que está la falla, de antemano muchas gracias
Hola, si la fuente de señal es demasiado débil, debe ser amplificada
does it use a lm3914 or a lm3915?
Hi, it use a LM3914
Amazing
Thank you!
Can we read 220 v ac waves darectly
Is not possible with this oscilloscope
Hola necesito ayuda, hice todo tal cual el esquema pero no funciona, si alguien me podría ayudar se lo agradesco, es urgente
Hola, puedes ser más preciso? cual es el problema?
Aewsome!
Thank you =)
your schematic has the 555 called LM555.. is that a mistake???
Hi, no mistake, they are the same.. 555 can be used as a abbreviation for NE555
This project was published sometime at the start of 90s in electronics for you magazine...
Yes, the circuit name is "AUDIO HISTOGRAM".
Is not an "Audio Histogram" The graphical representation is like an oscilloscope (Sine Wave)
Yes dear Stefano, you are correct.
Do you have any video of 2 or more LM3914 cascading in BAR mode. I tried for such a circuit, video, but most of them are not with clear explenations.
@@techstricksarts290 I have this: ua-cam.com/video/ka1sgL1lryM/v-deo.html
Alternatively search for my vu-meter videos with LM3915.. the circuit is the same.
Cool! Will it work with LM3915 on high frequencies?
Yes, but with this type of project LM3914 is better than LM3915
Lm3915/lm3916 is not suited because its scale is logarithmic. Your graph would be condensed at one end.
How much voltage does the input power?
Hi, works with 9-12V DC
@@Stefano91ste thanks, it's work now
Good!
Ese kese banaye sir
English please
Can I increase the row to 12 led ?or how to ?
Hi, no the max number is 10 (10x10 matrix)
@@Stefano91ste You can add 4017 in series sequential to make 20x10 matrix.
Likewise with LM3914/5/6 connect in series to make more levels vertically.
@@moristo Yes, it is possible, but the whole circuit should be revised
@@Stefano91ste For your new video.
Nice
Thank you!
Please upload circuit diagram
Hi, you can see it in the video
wher is schematic diagram plees
In the end of the video
@@Stefano91ste than you
Please give the PCB design
Soon I will make an improved version of this project on PCB with JLCPCB ;)
Have you created the JLCPCB version yet? Please make them available when you do. I will buy one!
I did not make a version with gerber files for jlcpcb or other pcb producers for this project.. but soon I will it :)
@@Stefano91ste Did you do this already? would love to make this!

hi E P S...
better use a plastic knob on the speeding control...
dont need use a screw tool
Hi, I did not have plastic knob at that moment..
I got the 3 ics, but i dont got all that smartness 😅
It is not difficult :)
Explanation please
If you look for the electric diagram, you can find it at the end of the video.. at 2:40
I wrote an article about this type of scope with explanations and everything here: www.eddybergman.com/2017/10/led-oscilloscope-with-100-leds.html
Very interesting and useful !!
Please write a new comment equal to this, i would like to pin it to the top.. if you agree
Excellent!
Thanks
Naice
Thank you!
È incredibile, ne sono rimasta felice. Vengo dalla Russia, scrivo con un pioniere. È possibile una traduzione errata. L'elettronica è il mio hobby, non ne so ancora molto. Rispondi alla mia domanda per favore.
Qual è la tensione di ingresso?
Se viene immesso un segnale audio, funzionerà?
Grazie.
Ciao, grazie mille!:)
- La tensione di alimentazione del circuito è di 9/12V DC - la tensione di ingresso del segnale non deve superare i 30V.
- Se viene immesso un segnale audio funziona, funziona bene con i segnali audio a bassa frequenza.
Hi, thank you very much! :)
- The circuit supply voltage is 9 / 12V DC - the signal input voltage must not exceed 30V.
- If an audio signal is input it works, it works well with low frequency audio signals.
hola me pueden compartir el diagrama
