I thought my computer was talking to me when the audio issue came on! ;-) Thanks for sharing!

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.

Nice review Steve. Cool looking clock too.

I thought the editing error was funny.. Sounds like incoming comms from the International Space Station 😉

Cheers

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!!!

Strange "helium man" voice at about 6 mins in. Nice clock.

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?

[bestamerica]

'
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

[johnberry]

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

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

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.

[dougkuechenmeister]

I'm getting ready to build this, Thank you! Great video. I'm subed

Ha ha what happens to the audio at 6:33 thanks for the video pretty cool clock

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!

[tomgray]

Thanks Steve. I wanted to get one of these, is it 12/24hr selectable?

[toddy]

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.

Can the temperature be set for Fahrenheit, and time to am/pm?

[toddy]

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.)

[dooronron]

can you stop it flashing between time, date and temp, ? mine does the same,

[gadgetuk]

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
