KevinHeron i tried it,but didn't met the problem you mentioned.maybe you could check the CR1220 or the power supply wether if 5V.

These are a great teaching aid clock, BUT - There is an inherent flaw in the programming / RTC or both. For months that have "double digits", the flaw shows up. If the power goes out for any length of time, when restored, the first digit (if it was supposed to be a 1) will revert back to "0". You will need to go through the setup procedure again to tell it month 10, 11, or 12. I had this problem with about (4) of them, so either there is a bad run of chips, or there is a bug in the programming. Either way, beware of the error.

KevinHeron The middle and the other LED that you made wasn't the same color,so sure it is not working.

I bought this to keep my SMD soldering skills in practice and it definitely does that - there are a huge amount of LED's to solder on. There are two problems I found though. The first is the instructions didn't make it clear that there are two colours of LED's provided so I just worked from left to right and ended up with a nice shade of blue for 80% of it and bright pink on the rest. The other problem is that it doesn't really look as great as it does in the pictures! You can barely read the time on mine because the LED diffuser is just a thick sticker - from a distance it sort of looks okay but its almost impossible to tell the time or work out which mode you are in without standing back about 20 feet from it. I'd considered flipping the front plastic so the diffuser is on the outside as that is very clear but who wants to look at a big white sticker? In summary - it's cheap and useful as a way to practice soldering but unless you're prepared to alter it to make the time visible then its not going to be any use as a clock.

KevinHeron it needs two 3V battery.

I seem to have been one of the unlucky ones who got a bad package. The LEDs just dimly light up.... That's it. So I'm requesting a refund as I (like others) have not heard back on possible solutions. Package was pretty beat up as you can see even a LED was chipped! The IC looks like a smashed cockroach. Seemed to be okay quality, I was pretty upset when I installed batteries and nothing happened. Today I received the other colors.... I will update if possible with those results. Bought these as an introduction to soldering for the kids, so I hope "Maker Monday" isn't a bust!
