Fixing a faulty meteor icicle light. 

Nice job bigclivedotcom. I enjoyed your explanation of the failed Led and the multiplexing.

I bought a couple of these sets last year, the main problem I had was they snapped in the wind at the strain relief. One set had a really dodgy power adaptor with a pcb cut out from a random piece of equipment. Thanks for the video

Proof that Clive is a good person: he uses snips to bend a lead, and he doesn't accidentally snip it off.

Nice explanation! I haven't heard of it yet

Got a set of the RGB metor lights from banggood (SKU096512), and they had a capacitive dropper power supply, and the capacitor was getting quite hot so was not impressed. I noticed on the box (yes, it has a retail box!) it said 5v output, so precariously disassembled and metered the PSU, and yes, it was varying from 3v to 5.5v dependent on the lights. So removed the PSU, and put a USB plug on the end, and it now runs from any old 5v USB socket, and draws at most the massive amount of 1.42W (or 0.25A @ 5.22v) and can run from a 2200mah usb powerbank for... a very long time? lol A far cry from the 7W on the banggood site, or the 5v @ 1A that the box says :-O

Quite informative, thanks a ton for you spirited videos

If you have trouble with heatshrink wicking water into things, I've found nail polish works well. Clear stuff looks quite professional even if you just slap it on.

The second you said tristate, i thought about the tristate buffers in computers. The matrix plus reverse polarity does give double the choice, also the limited potential applied to two series leds wont light them, quite sneaky really :-D

Hi, another great video 👍🏻 I have a set of meteor lights with a very similar looking circuit board and was wondering if you could assist me? When taking down my lights last weekend I noticed one the the tubes had three pairs of LEDs out so I opened it up, checked the LEDs and they aren’t faulty? I noticed the 8pin chip appeared to have a hairline crack, so I unsoldered and indeed it broke in two!? I have no idea where to get a replacement or even the spec if needed? Could you point me in the right direction? I have an image of the chip with codes on the back side. Cheers

Ok, RU-vid recommended me this video under the category "Astronomy".

Just wondered how you identify the positive and negative sides on the replacement leds (and on the boards) - I'm assuming these are marked but haven't yet had a close up look at one.

Dear kindlly please, we are a company in the field of installing urban lighting elements and we use your products. One of products that has been installed (Led Snow fall tube) has the following problem: When the weather is rainy, the light inside the LEDs is cut off, and after the humidity area dries up (about two days), the light comes back on. The used (power supply) is also a product of your company and has no problems. Please advise how to fix this problem if possible.

Our strand has just dimmed to the extent you can hardly see them. Is this a similar issue or different?

Fun stuff. Thanks!

Hi, Can I change the falling rain light effect of this light to constant on light?

I just bought a set of these at the bin store. The aren’t coming on at all. Any ideas on how to get them to work?

Great video! Do you know how to wire the lights if you separate the chip board into different sections?

3:30 Wouldn't the first three LEDs (the right hand side of the three leftmost LED pairs on the page) also light up in series in this arrangement? Or did I miss something?

Any tips or what a person should buy if one would want to become an electrician?

very good thank you for building

No dislikes thats the first time i have seen that well done everyone

Hi You’re obviously a man that knows his electronics and LED Xmas lights! Cheeky question - I have a set of faulty connectable outdoor LED icicle lights which aren’t lighting up at all but will allow power to pass through and illuminate the next set in the chain???

It's that one there... :P Amazing to think that one component can cause such a big cock-up, but that's what happens when quality control doesn't exist... :\ And as for those generic snips, I use them too, though Rolson branded, they wear out fast... :P

It is not necessary some PIC or clone of PIC, it could be some ST product (among others). ST7LITEU09 have same pin-out as as PIC12 series (Vdd, Vss, reset are on same place) and Chines use ST microcontrollers in most of their designs (they are cheap and as much important for China they don't have any risk of import ban on them)

can u change the pattern

i have 20 of them with cool white led,s

i watch for more videos
