Part 1: How to generate 100% accurate 1Hz clock pulse with crystal oscillator
Вставка

- In this video, I've explained how to generate exactly 1 Hz clock pulse with crystal oscillator and frequency divider IC CD4060. The value of crystal oscillator I've used is 32.768 KHz.

I love how I have the same oscilloscope lol. I am basing my cmos alarm clock based on your lessons. I've spent like 100 dollars on chips and buttons since I discovered your channel and I don't regret any of it
I am very impressed with the clarity of your teachings. Thank you.
You're welcome Sir...!
Your teaching method is very good...It is very easy to understand and to make. And you explain both theory and practically in the easiest way in your video. Thankyou for this amazing video.
In this modern world, where only we use microcontrollers to almost everything... It is always good to remember "basic digital electronics". Greetings from Colombia South America.
i just built the circuit. Awesome video man. i like how i understand the circuit not just know how to copy yours. Great work man.
FULLY AGREE WITH EVERYONE ELSE I LOVE ALL YOUR CLEAR WORK YOUR AN EXCELLENT TEACHER AND THANKYOU FOR TAKING YOUR VALUABLE TIME TO SHOW US ALL THANKYOU AGAIN
Very nice video, thanks. I was struggling to make it work, you have explained very nicely and now its working for me.
Please teach how to use oscilloscope.
I already made this 1hz circuit by watching your video.
I want to buy DSO138 oscilloscope. But I'm still not sure if I'm going to understand it.
Thank you for helping me get my CD4060BN chip working with my crystal oscillator
this video really helped me. you're amaring at explaining
Good instructive video. Thanks for this.
great no-nonsense approach. Thanks for the info.
Crystal clear explanation sir. Thanks a lot...
I tried the crystal oscillator circuit and it works. However, every other source shows a pair of feedback capacitors which you have omitted, so although it works, I'm still not sure the circuit is correct.
Hey can you share those links of the sources
@@abhraneelbasak722 UA-cam does not allow me to post links, but you should find it if you search for Hacker's Bench Crystal Controlled 1Hz Time Base Clock
If a conncect a gate with this clock signal it will create noise or not?
You may use the second pulse generator from analogue clocks. It's a bit easier method.
Anyway I am fascinated by your knowledge. Keep it up. Is there any way to personally cantact you?
You can use a flipflop to divide by 2
Excellent presentation sir
Thanks for the video, I seem to be getting a 10hz output using the same circuit as you with a 32768Hz crystal and 330k resistor, I'm not sure why, any help would be appreciated. You also seem to use a different circuit to that used on the CD4060 datasheet?
9:08 asper the video he said 330k resistor, but insted of 330k he used some resistor having colour code brown brown yellow gold as per the colour code that is 110k ohms with a tolerance of 5%. Bingo 👍.
If you got 10hz you just check and change the crystal that will fix your issue.
same here. The only way I can lower it is by using more resistance. Around 740Kohms
Hello Sir. Very good video. I found some other circuits from internet. But they connected some capacitors and resistors. Different values in different sites. Is this necessary?
Actually capacitors are necessary. I've another video on CD4060. That will help you.

@@EEWave Thank you
Can you clarify ic number?
Is it CD4060 or
HEF4060
I accidentally bought HEF
And i couldn’t find Your 4017 video. Please provide link of the 4017 video
Both are same. The number (4060) is important, not the prefix or suffix.
The video link on 4017 is given in the description section.
Why not just use a clocked J-K flip flop to divide Q14 by 2?
Yes, you can use jk flip flop ic 4027 or 7476.
Can you explain why you use a 330K resistor ? Is there any equation or something to figure out the res value? btw the video is great, thank you for your instruction
Some people say it is a damping resistor which will reduce the chance of damage of the Crystal oscillator. Or some say it is border frequency resistor. If you see the datasheet of IC 4060, then you can find the typical Crystal circuit where they have used a higher valued resistor in the oscillator circuit, and I've taken that circuit. Till now, I don't have any satisfying answer to your question, I'm also searching for the answer.

@@EEWave I get very high frequency oscillation. I need to put around 600kohms to be able to see the pulse. Also, when I remove the crystal I don't see a change.
How to get 1hz frequency from other values of crystal oscillator like 25 Mhz, 10 Mhz ,4 Mhz, 8 Mhz , 32.767 Mhz?????Actually I tried with other crystals also and applied your calculation technique but unfortunately did nit get the required result...
In this case, we can not use 4060. We have to use other counter like ÷5 and ÷10.
U can use 4060 with any 4040
Thanku you so much ❤
Nicely done
A very good explanation but sadly not quite accurate headline. It all relies on the crystal actually oscillating at the stated frequency. But it varies, mostly due to temperature change and age. That's why there are other devices, some quite expensive, such a txco devices(temperature compensated crystal oscillator) which get much closer to '100%' 1 Hz.
How do i convert it to AC keeping the 1 Hz frequency ?
very thorough, thank you
Glad you enjoyed it!
Thanks very much. Could you tell me why you've used the 330 kilo ohm resistor there?
It is a damping resistor. It will reduce the chance of damage of the Crystal oscillator.
@@EEWave I've applied the same circuit...But instead of using two CD 4060 , I've used a CD 4060 and a HEF4060...and I'm getting higher frequency than 1 Hz...Does this affect?
You should get 1Hz frequency with these two. They are same. What is exact frequency you are getting?
very nice. thank you.
This is NOT 100% accurate .. There is missing some capacitors In the oscillator .. Yes 1 hz seems accurate but it’s a dividend signal .. I builded a few of these from this video here and used Them for time base .. Resultat the clock loose 3 seconds a day .. Because the 32768 hz crystal differ with 1 hz ...
When divided to 1 Hz .. it’s 1/32768 hz wrong ... This oscilloscope is not accurate enought to show 1/32768 hz ... Or in otter words the 1 hz signal is 0,000003052 Hz wrong ..
Hey can you help me out with this cloxk pulse
good explanation
Dear Sir, please, can I have the codez?
Hello Friend, it is done without microcontroller. So coding is not required.
in the nail kkkk
awesome
😊😊😊😊😊😊
Fucking brilliant video :)
I'm building a CMOS clock with it. Check it out: hackaday.io/project/176063-hackaday-clock-a-day-entry-cmos-logic-clock
Thanks for working out the value of the 330K resistor. If it was you that worked it out. ;)
Hi sir
Hindi me bolne me kya problem hai,
