Wow, this was so helpful for my puny teenager brain, it really helped me understand integrated circuits a bit more by doing these projects! Thanks man!
Glad it helped!
I know this is an older video but I love this. You explain things very well any your references are very helpful.
Glad you liked it!
Wow, such an awesome video, Was really helpful. Keep up your work.
I like this very much! Good job, Sir! Please make more videos with discrete logic components.
Best tutorial I've found so far
Thank you so much!
"Thank GOD", and thank you very much for your support and time 😉 I REALLY like the way you presented your video 👍
Thank for encouraging!
@@Neutrino1 Your video presentation was REALLY good 👌
yes, we need to know more about this circuit.
thank you
Thx u so much
i want to make this waiting for long time...
Really Thank you sir, Great video ❤
There is a trick to cutting acrylic. Line both sides of the cut with clear packing tape and cut through the tape as you are cutting through the acrylic and it won't crack.
Thank you!!
@@Neutrino1Oh, one more thing... Wouldn't segments 'e' and 'f' be sufficient for detecting a 6?
this is brilliant
Great video, well explained.
Just to add, I have now built this. Great fun to do. I used a quartz clock module to derive second pulses from the coil, via a buffer.
Nice work and Great tip!
Nice. You are very creative! Its awesome to think about what you can make with just discrete components :-)
It's really fun working with electronics!!
Awesome bro...
Keep it up
Very helpful
Successfully built it.
I need some troubleshooting, and need a more permanent power source, but otherwise I completed the work.
I used a 32768khz crystal and 4060 ICs to get 1hz pulse.
But otherwise followed this tutorial exactly.
I wanted to be an engineer, but couldn't because of parental pressure, but guess what? I don't need to be an engineer to enjoy these things...
The wires behind the board are REALLY messy. And it's gonna take forever to troubleshoot...
very good keep it up
keep it up good work
genial,felicitaciones y un saludo desde Colombia.
Gracias mi amigo
bro amazing
also its possible to supress the seconds counter and place the 1HZ clock input directly onto the minute CLK pin right? or im wrong
If I am making final year project, if I choose this, please can I get a clear cut photo of the connection of the circuit🙏
Really appreciate your work.
But there is a tiny mistake, 555timer oscillator uses RC network which can't output a stable oscillation of exactly one hertz, it may be slowed down or become faster a little bit depending on air moisture, temperature of the surrounding. Then your clock will lead or lag over time. So my method of getting a second pulse generator in a cheapest way is to use the circuit of a wall clock ,it uses crystal which is very precise and accurate. Then it's ok
Yes yes! I agree too, this is just for making the circuit simpler and even in the video i suggested to use a different oscillator circuit.
@@Neutrino1 I have made a digital clock in a much simpler way without a microcontroller (cheapest,just one dollar) u can check it on my channel if u are interested.
Video title is DIY LED wall clock using wrist watch (in hindi language)
then which timer should be used instead of IC555 ?
@@mujtabaqamar1712 CD4060 with a crystal 32k resonator should do the work

Sir, namaste
I have a Ajanta 103 model digital clock. It displays week by a single LED. I want to add week name aslo to its cirxuitary. Will you please tell me how to do?
Cool!! ⏰
thank you!!
I appreciated your works! would you mind if you could give me the link of your own schematic diagram not in the link,I saw you used a many diodes and capacitor but the circuit diagram you gave was only 2 diodes and 2 capacitors.. I want to make for my project credits by you..Thanks...
any idea about how to make this work as a stopwatch as well ?
Nice 🙂
Thanks 😋
Amazing broo
Thank you!
@@Neutrino1 bro can we replicate the circuit of digital clock like that of ajanta
Thanks a ton...I'm planning to do this project...But I need to display in a 12 hr format..So, after 12, I gotta display 1.....Since this 4026 ic resets to 00 as it reaches 24, is it possible to use the same ic for this my purpose..Your help would mean a lot
It would be complicated using the same IC..But u can do this, delay the reset pin(connect 4 not gates and a diode whose +ve connected towards the output of AND gate) from the hrs display and feed it too the clock input of the hrs ic. I guess this should work!
how you to make the timer? all details
can you do this in breadboard? PLEASE
How much current does the circuit exactly need.? Plz give reply ASAP
Nice job, thanks. Would you mind sharing the circuit diagram?
it's In the description
Hello in the circuit there is no ic 7414. The link you put does not have the 7414. Can you attach it here?
You don't need that, even without that it would work.
Does the minute hit 2 after 60 seconds?
Dose the circuit diagram what u provided is completely good or we need any changes
?
Yes, I made few changes in new circuit diagram.
Dude can I ask? Can you show me the pin 8 and pin 16 of IC 4026 connection in the circuit?. It'll help a lot for my project. Thanks
DC source used?
probably is late but for cuttin the acrylic you can use an utility blde and a strong ruler can be metallic or otherwise metal is better
sonyou place the ruler over the acrylic piece you need to prevent scratch and do multiple pass with the blade in both sides once its marked you can break it like glass no need to cut it all the way
also with a 4060 and a piezoleectric resonator could be more precise than a 555 duento the fact the 555 relies on resistors and capacitors that have high tolerances
Excellent video. Please tell me that 74ALS11N is same 7411. Can I use it. Please reply.
Yes its the same!
Ok thanks for your reply.
I will try iit on Proteus 8.
@@virendersingh6027 that will be great!
Sir, today I have designed two digital clock in Proteus 8. One digital clock (4 digit) using ic 4026 and ic 4017 and ic 7408 is working fine. I have also designed your circuit. But seconds is working only with missing e and f point of segment. Even no switch is working. Can you please help me. And please tell me do you know hindi because my english is poor.
Thanks...
Which design and simulator software you used for this circuit?
AutoDesk Egale
What is the software that u used to check the connection in pc?
Use Proteus circuit simulator
Sir I want to make this project but the problem is that you connected resistors between IC 4026 and SSD in final circuit you made in video but these resistors are not present in the circuit one you give in description. Sir kindly reply ASAP.
It's not necessary placing so many resistor even though it works(they are just for aesthetics) just one 470ohm resistor on cathode side of each SSD would do fine.
👍👍👍
Hello my friend I just entered the link of the circuit diagram but it's deleted so if there is any way to find it, and thank you so much

How are you dear
Thank you for good explanation
Question :
1-what is the value of resistor before 3input and gate?
2- where we use in circuit that diode you put its link in content ?
I'm waiting for you 🌷
Also can i know is this 24 hors or 12 hors ?
Hello. Can I use the cd4017 for this?
Nope... CD4017 is counter,but CD4026 is counter with 7 segment LED driver.

Sir in your diagram you have shown 8 ics but in the vedio it is shown 9 ics which 1 ic is missing in the ckt pls reply
The 9th IC was for denouncing circuit. It was redundant. It's replaced by capacitor in the circuit diagram near the button. I have talked about this in the video too.
could this circuit work as stop watch ,as it is work as time Keeper ! that mean having start/stop switch and reset switch!! thanks in advance.
yeah sure!
Have a switch for the clock input of seconds IC, then the circuit will pause/stop if clock signal is interrupted and take all the reset pin from every 4026IC and connect through switch to +vcc, when the switch is pressed the whole clock will reset. Thus making the circuit a functional stop watch. Also by playing with the clock frequency you can adjust the accuracy of the circuit.
@@Neutrino1 ok bro, i have a small question ,what is the function of the two push button in the circuit. it seems not obvious to me.
@@sherifahmed7800 To adjust the time.Since, the clock reset when power is down.

Logic gate 24 hr reset is very wrong. If you’re using a 3 AND gate to look at D,E, and F to reset at 24 then it will also reset at 04,05,06,08,09,20. I built this circuit and my clock hours won’t increment out of 00.
whats the v for the supply? 9?
It works from ranging 5-12v

Bro .. this is a nice project but I face a problem in making this ... I made this project almost 5-6 times and and every time my hour display will return to zero after 19 .. instead of 24 ... How to solve this problem 😥 ... Else everything is ok
Can you please provide the additional circuit that you attached to prevent bouncing .. in vidieo , you did very fast ... I unable to understand ... I think after adding that circuit my problem may resolves
There is a mistake in his AND gate connected to the Hours-Tens digit. In reality, you need 2 AND gates (or one 6 input) that tests both digits of the hours for "2 5", and RST then. There are other mistakes in the circuit diagram as well.
I had the same problem when I built this circuit. Unfortunately for me, I designed this circuit onto a pcb and ordered a few of them. Looks like I have to scrap them all and start over. I should have double checked his schematic before making it. Oh well.
it's good. but too deep explaination.
You talk WAY TOO FAST! As a novice, this video doesn’t help me, at all.
I will try best next time to make the video in slower pace.
Thank you kindly.
