Hi Edifred. I got this kit a while ago, the rainbow led’s caught my eye but I couldn’t find a YT vid on a full build which I use to mainly to find flaws in the chinglish instructions. In this case the Banggood instructions were fine. Coincidentally I noticed the "ribbon" of led’s were "crinkled" (damaged) in exactly the same way as mine which wasn’t too impressive, anyway they turned out fine. After a recent couple of kit assembly failures I took my time on this one. I still managed to stupidly install an led incorrectly and on almost the last stretch (everything had gone so well) I bridged some pads on the last side of the big IC (the one you fried). Try as I might with wick, sucker, etc it got worse. All the while I thought this heat is going fry the chip. In the end I used a massive chisel tip across multiple pads and hey presto the solder jumped into the pads, wow! Anyway I was convinced I’d damaged the IC. I persevered on as is my way, finished the build and it turned absolutely fine. Now, perhaps like you, it seems I have too many of these clock kits but this one is by far my favourite, I’m using the rainbow setting. Anyhow, I’ve gone into this long narrative to try to persuade you to get another kit and try again because in my case this turned out to be, as I’ve said, my favourite. Best Easter wishes!

Thanks Jay. Yes, I think I will get another. It looks a nice one and would like to get one going. Second time lucky provided I don't screw up again!

Hi, shame about your build problem, the positioning of your leds is very impressive :) , i am building this now with no instructions supplied..., there are 3 different values of resistors supplied, can you help me by saying what value R1, R2 etc should be ? , help would be appreciated if possible, thank you :)

I did the same thing on a clock kit that uses the same microcontroller. The picture in the instructions showed a circle as pin one. I installed mine the same way and it didn't work. Turns out the morons who make the chip decided to make three types, one with one circle like shown in the instructions, one with two circles but one smaller, and one with three circles with one smaller. I installed it with the circle as pin one and when it didn't work I saw it had two circles and after finding the data sheet, pin one is the SMALLER one. Why in the F would you designate pin one by a circle and them put multiple circles on the chip and especially make pin one the smaller one?

I ordered the same kit. I agree, the LEDs took quite a while. As for that chip that you fried- almost have to use an eye loupe to try to solder that thing! I think I fried mine too- got too much solder on it so one side has solder across many of the contacts. I found that if I just put some flux on the contacts beforehand and then didn't use any solder and just touched each contact with the soldering gun that would have probably been OK. I did that on the other 3 sides. I can't get the solder off the contacts on the one bad side- I have ordered a solder sucker and will try again but pretty sure I have fried it and messed up the board in trying to remove the solder on the one side. I have a picture but can't atch to this comment. Maybe should do the chip first before the LEDs. Then, if you mess up the chip you can salvage the LEDs. For me, this is a difficult project and I'm a novice but I have built 2 other led kits with success.

I built one of these. It worked OK.

I'm guessing you can't just buy a new chip as it won't be programmed?
