Updated Item: www.banggood.c...
This item was sent to me by Banggood.com. Overall this seems to be a nice kit for the price, and certainly an attractive clock when powered up. It features CR2032 battery backup for timekeeping and various colour combinations are selectable on the website when purchasing.
Thanks for watching! #ElectronicsCreators
I thought my computer was talking to me when the audio issue came on! ;-) Thanks for sharing!
Nice review Steve. Cool looking clock too.
I thought the editing error was funny.. Sounds like incoming comms from the International Space Station 😉
Cheers

Strange "helium man" voice at about 6 mins in. Nice clock.
+Eric Gee Yep, fail on my part trying to edit while everyone is asleep.
Too late...I desoldered it and broke 4-legs...damn it! After I removed it I thought about doing the exact thing you advised...to just leave it in. I soldered the socket in and inserted the chip with the broken legs and did a continuity test on all the legs and all were making contact so I'm going to cross my fingers to see if it all works once I'm done putting it all together. As I mentioned in the other post I don't know very much about electronics and thought you had to have a socket installed for the chip to work. Now I know better and it was an inexpensive lesson. I will keep you updated...if that's ok with you.
Thanks Steve. Cool little clock.
The new version of this set, the clock has become much larger, and is now completely made on smd elements, the usual LEDs have been replaced with RGB th-cam.com/video/sI8WzTf9uBQ/w-d-xo.html
I'm getting ready to build this ,Thank you! Great video. I'm subed
Thanks Doug
Nice
Good Job, I enjoy kits like this. I am going to get one. I would like to buy one like this as the one I found was mostly surface mount and they can be a drag to put together.
I have 2 of this, in red digits. I bought them already made (welded). But in NONE of them, the dots (DP1 & DP2) flash in time MODE. Is it a Firmware problem? Can you scan this instructions. I can't find them anywhere. Thanks my friend!!!
Hello. Led display anod or catod?
Hi Steve!
I came back and watched your video again. My clock, which we discussed 1 year ago or so, didn't work properly after the "fixes" we talked about so I put it for 7-8 months. Powered it up again and it works fine and has been since then! Did it "heal" itself? [strange isn't it?}
Now I have the upgraded version {EC1515B VO3} which I built. Firstly it powered up but many of the LED patterns didn't work right and the clock face didn't either so I went back and redid the solder points. Now, when powered up all it says is "EOR 3 "(Error3).
Any idea what's wrong now? I built this for my 7-year old grandsons' birthday (in 2 weeks) to teach him how to tell time. I can't find any info on theses error codes, even from Banggood whom I purchased it from.
Please help!!!!!!
Great tutorial, thank you. Can I ask you please, how many solder connections to the mini usb should there be? all the pins on mine dont appear to be long enough to go through the board to solder them. Thank you very much. John... :)
Can i connect it straight with usb cables ? Not to usb ? Thanks
Nice review, can I ask you where I can buy the little device you use which displays the voltage at the end of your usb socket please?
Ha ha what happens to the audio at 6:33 thanks for the video pretty cool clock
+charlieoscar09 Bah. That's really annoying video editing fail. Ah well
Not to worry thanks anyway for review
Thanks Steve. I wanted to get one of these, is it 12/24hr selectable?
Yes, you can switch depending on your preference
@@sdgelectronics Thank You
Hey there, I've put together one of these myself and have run into a little issue. When I plug the miniUSB in, all of the LEDs light up, but stay on constantly. The buzzer makes a steady buzzing and the clock reads Eor2. I'm gonna try to lift the crystal off the board, but any other ideas? Thanks!
EOR2 indicates a failure of the thermistor circuit. Check your soldering and be sure the thermistor (RT1) , which reads the temperature, is properly installed.
Also be sure you placed a 20k resistor in the R10 position on the circuit board.
The thermistor looks very much like a glass diode in appearance.
Hi Steve...I'm back again! All finished but when plugged in the clock reads ''Eor 1". The instructions, at the bottom of a page shows that error but doesn't explain or show any solutions. Any idea what's wrong? (the LEDs don't light up...just the clock face)
Thanks in advance.
The error indicates either of a soldering or connection problem with the DS1302 (8-Pin) Clock chip. Depending on who you bought the kit from, they may be willing to replace the chip or the kit...
Rick Allen...thank you very much for getting back to me! Now I know where to start looking to hopefully solve the problem. I have two more kits (B versions) so I'll look to see if they use the same chips and/or clock. Thanks again!!!!!!
Rick, I replaced the chip with another I had from another kit. It worked, but only for a short while. After about twelve hours of run time the clock starting malfunctioning. Bought it from BangGood and if you are familiar with them then you know returning defective goods requires at least one video for them to rview, I won't bother!
Thanks again for your help!
Nice Video Steve :) could you provide a link to the usb meter you are using?
+Dave _ Hi Dave, take a look here: th-cam.com/video/vpRN6XXX7WQ/w-d-xo.html The link is in the description. Thanks
+SDG Electronics thanks a lot
Is there a way to change the time display from 24 to 12 hour display?
This version does not support 12 hour time display. The newer version (EC1515B) provides this function and Fahrenheit temperature display as well.
Steve, I screwed up! I put the small clock chip on the PCB and soldered it in not seeing and realizing it had a separate socket that was to be soldered in...have I destroyed that chip? (I feel so stupid but I'm fairly new to electronics which is why I bought this kit to practice on.)
It should be fine unless you overheated the chip. Turn it on and see!
I have to solder the 48 red LEDs in...I haven't completed the build yet. Will get back to you and let you know how it turns out. Thank you for getting back to me so quickly...I'm about to desolder the chip...wish me luck!
Don't desolder it, if it works then leave it as it is.
Hi I've just built this V3 and got it going fine, but, it's gaining 2 mins an hour, any idea what may be wrong? Clock chip or the crystal perhaps? Cheers
Alan Clarke you could try adjusting the load capacitors on the 32kHz crystal as you don't have access to anything else.
SDG Electronics any idea what to has I don't have any experience at all, just soldering lol
Can the temperature be set for Fahrenheit, and time to am/pm?
This version (EC1515A) does not support either 12 hour time display or Fahrenheit temperature. The newer version (EC1515B) does support these
functions.
If these kits came with the source code, you would be able to mod them to do that kind of things. Those little 8051 clones are very versatile.
free of charge - whoopie, not ideal, what for esd on leds and resistors. then touches ics willie nillie.
can you stop it flashing between time, date and temp,? mine does the same,
As far as I know there isn't a way to stop it. It's a bit of a shame really.
try to short pins 6, 7 and 14(gnd) on STC15W408AS to stop rotating and displaying only time. it works on this kit : www.aliexpress.com/item/Compact-4-digit-DIY-Digital-LED-Clock-Kit-DIY-Clock-Accessory-Light-Control-Temperature-Date-Time/32616457562.html
+Milan Rosic will give it a go. thanks Milan.
The newer version of this clock supports changing the display to only the time or alternate display of time and temp thru pushbutton options. The newer kit is model number EC1515B.
como obtenerlo
OK. Started off easy enough (unpack stuff from bag) then you lost me with the tech talk. I'm sure eventually ill understand
Complete Instructions for all the clock's functions:

Here are the updated instructions for the latest version of this clock.

Audio glitch around 6:37

can this DIY rotating LED clock kit use a pack of four AA batterys = 6 volts...
would be work fine or better not...
will it burn out LED lights or two microchip controllers or both
