My first job out of high school in 1969 was working as a video editor for a television station. Yes, making a good video takes a lot of work. I have taught in public schools for 40+ years; twelve years as a high school electronics teacher. This is the best kit build video I have seen. Thank you.
Great video. Very clear. Just started building mine and found it very helpful. I particularly like the voltage checks before moving on to the displays. Oxford UK
Wow this video is good, what is wrong with UA-cam algorithms that I've never seen this, all I watch is electronics videos. I had to search specifically for the clock for this video to come up 20 spots down. Bravo, great job.
It seems Banggood has stopped selling these, but I found more or less the same clock on eBay. It has a slightly different circuit, with fewer components, but the same functions, and came in a choice of red, blue or green LEDs. I have a blue one that's working nicely. This video was very helpful, especially for setting up and for case construction. For the first reset, I had to try a few times, pulling the plug between tries - it seems quite picky about how close together you press the two buttons, and does weird things if you "miss". I hope it dims properly at night - the blue LEDs are very bright.
If you look very closely at the film you put over top of the display, it's actually like a double face tape, sort of like window tint. Peel the layers apart and stick it to the led modules and then cut away the extra film by placing the display face down on the table and using an Xacto knife to cut around the edges. It takes a little while to get the layers separated. I had to use the blade of the Xacto knife to get it started. It's a more professional looking job when it's done that way because the tint fits nice and smoothly to the display and you'd never know it's a sticker. I've built a few of these.
i have a MSM9004-02 in my car that is severed from the stock radio, so it doesnt work. Can i some how make it into a stand alone clock? I have located the pin out of the chip to 10pin connector vcc 5v and LCD voltage, rest, load, clock, and ground. what do i need to make it work independently?
Hi, I hope you can read this, I am desperately in need of guidance , 2 weeks ago I assembled one of these and it worked fine with a 5V power supply, then a few days ago I by accident connected an identical looking PS with a 6V output and the clock flashed for a moment and then never worked again even with the correct PS, I need to figure out what part I have damaged but I'm a total novice and find it hard to troubleshoot, don't know where to start ,please help me if you read this message, .
I had a quick look at the circuit diagram and there is no over voltage protection in the circuit. Both the microcontroller and the Ds1032 have a max voltage of 5.5v, so more than likely you have damaged one of those two.
@@techydiy , that's what I suspected , I have compared the values of the resistors and capacitors and so far, they are all salvageable ,all except the microcontrollers , at least I learned something , I sincerely appreciate your quick reply and your help. you were the only one that came through for me and it helped immensely.
I didn't know it was a (Red LED) in the back of the clock? at 18:12 everybody on UA-cam has a different way to build the clock some doesn't show all component skip parts of the built or has part at the end they didn't show at the start..
Greeting from Australia, I have purchased these units for a school project. When we power the units up they give us a code of H5C5, we reset as per the instructions but they do not go to 7:59 and then move to 8:00 and beeps. All of these units are doing the same thing, what ar we getting wrong? Thanks, Trevor
It seems a bit unlikely that it's a soldering fault as they are all affected, so check component orientation. Check that your using the correct instructions. Check the voltages on the components. Failing that go back to the supplier.
+Gladys Datita I use a solder sucker tool or desoldering braid, but that often doesn't work for an IC socket, so in that case I would add more solder to bridge the pins/pads, run the soldering iron along the pins and then remove it.
Hi my name is Allan l live in the Stoke on Trent area l am about to build one for myself now retired in my 70 old radio ham l woud like to get back into building small project regards allan
@@techydiy gotcha. I have a problem with my alarm aswell.. i somehow cant turn the alarm off, do you perhaps know how i could fix this? I thought about taking the piezzo buzzer out but im not sure if that will break the circuit (im not planning on using the annoying alarm noise anyways)
Thanks a lot for this video. I’ve purchased the exact same kit and my son and I will assemble it this weekend. Your tutorial helps a great deal. Greetings from the Netherlands
I’m looking to make a retirement gift from something that has buttons. I’m thinking all I have to do is wire the function and plus keys to the buttons on the retirement gift. Keeping everything else the same as the video. I hope it works.
For the love of techydiy. I was stuck on that pesky Diode, not knowing exactly where it went lol. The Chinglish instructions threw me. Thank you Sir. And what black magic is that red led for? I take it, it never came in your kit? Chris.
I am from Pakistan and want to build this clock because Chines don't provide any type of manual so it is very convenient to explore youtube for information.So I am very thankful for your very informative Video.
I purchased this kit a few times and it was always hard to find part positions and part ID I liked your video and learned alot. I am going to try again Thanks
Greetings I have built up to 6 of these and they are very good kit for the money and they make good presents, just one thing I noticed all of them slowly lose time and you have to reset them, I thought they are quartz controlled, is there any mod to improve the accuracy. regards
I'm curious if there is any way one of those 7-segment displays can be modified to use RGB LEDs. You know, for giggles. I've seen another creator make this clock, and the backs of the displays are removable.
Get a magnifying glass and check the solder joints for dry joints, bridges and shorts. Make sure the components are all the correct orientation and values. Usual stuff basically.
@@techydiy the photoresistor and thermistor work and the temperature changes the value properly, also the clock counts and i can acces and adjust day, date and alarm. But it doesnt change with time, it just stays on 7:59, I plugged it yesterday and it worked perfect. But today i change it of place and it didnt reset anymore
Same here. Assembled just fine. All solder points are clean with no bridging. Temp is fine. Beeper works. But no "ticking" as it were. The middle dots don't blink; time never advances. If I reset it, it never moves from 7:59 to 8:00. Must be a bad crystal. Shame, it was a fun build and looks cool when done. Nice video though!

Neat little clock kit. I have seen them at for sale at Banggood's site. Thanks for the tutorial. Greetings from NJ USA.
Watching from Pennsylvania USA. Does this clock support 12 hour time?
Now I understood to set the watch! :-) THX!
Glad it helped!
Watching from India, i just ordered and was curious to know more about it , i actually ordered talking clock version
It doesn't come with battery 😅

Good tip. Thanks
what does the chime do in this context? great vdo thanks.
Is there a way to disable the other functions and only display time?
Not easily
But you know what needs to be done? Can you tell me? Thanks
i'm watching from pretoria
Can it configured to show 12 hour time format instead of 24?
i have a MSM9004-02 in my car that is severed from the stock radio, so it doesnt work. Can i some how make it into a stand alone clock? I have located the pin out of the chip to 10pin connector vcc 5v and LCD voltage, rest, load, clock, and ground. what do i need to make it work independently?

What does that LDR do?
It senses the light level and dims the display at night.

Hi
My alarm doenst turn off, what went wrong?
My two kits arrived today. Viewing from Sudbury, Ontario, Canada. Great video! (second time I watch...LOL)
How do you change the time format from 24 hours to a 12 hour clock? And also how to change the temperature from celcius to farenheit?
This Clock doesn't change to fahrenheit or from 24h to 12 hour format.
Is there any way to turn this clock from 24 hour format to 12 hours
I am looking for answer to the same question!

Is there a way to change between 12 and 24 hour mode?
great video, will buy one for my own. Greatings from The Netherlands

Light flickers when dimming, how to fix this? I want the dimming mode to work properly
Rewrite the firmware to increase the pwm frequency probably

How much sirilankan saline market.
My clock won't change minutes. All other functions work.
What did I do wrong?
Excellent video.... Well done... Great little project...!
Many thanks. Your instruction for setup has helped me a lot.👍👍👍
what would be the point of error if for each display panel only one segment turns on?
many thanks from midwest USA
7 sagments are anode or cathode???? plz
dosent work i have to push in and hold butions to turn on
Mine is stuck at 759 :(

Just found this channel. Love these types of videos!
Nice!! Clever case assembly!!
how to set 12 h mode?

Oddly I cant get my temp display down below 21c ?
hi C...

i have one LED clock kit with white LED...
dont need to use a LDR on the PCB...
still work with full light on
nice
Can I solder a 100 mm 7 segment display instead of this display? Will there be a change in operating voltage? Can it run a large display?
Depends on the display.
hello,
can you programmed ICS and circuit design ? it's for educational use for students.
vijay
can you send program ed ics
It's not my design, it's a kit. For the supplier follow the link.
At a guess you probably can't buy the components for the price of the kit.
Mine doesnt resets :( any idea? It displays 7:59 and stays like that
