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.
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.
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
@@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)
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...
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...
Hi 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 🌷
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
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.
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...
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?
Bro i follow your circuit diagram but my hours display shows 19 as the maximum limit ( instead of 24 ) and then it returns to 0 . Means sirf 19 hours hi show ho kre hai ... How to solve it ?
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!
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.
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.
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.
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.

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.
Where is the circuit diagram
Cd 4026 etne555 one clock one kilo hz
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.
