really beautiful light display. they really thought this one out. and especially clever what they did with the timing on the leds, they don't have time to get out of phase. and yes; I want to win.
Great wee board albeit the heart shape is a bit naff. I suppose the LEDs could be mounted elsewhere as you see fit as the sequences are quite entertaining! I want to win!
The LEDs aren't being controlled. They're just not random. Each time you power on one of those LEDs they restart the same sequence at the beginning. In groups, they'll remain synchronized for quite some time (30+ seconds) before the manufacturing differences cause them to drift apart. Since they're being turned on in a close sequence and left on for only a few seconds at most, the patterns emerge from the LEDs design.
I want to win but I bought the exact same kit from aliexpress with several spares also but mine didn't flash like yours did; I replaced the crystal but same. I either get a slow fade up and down with the crystal in place or random light flash with the crystal bridged. I wonder if mine is programmed differently?
This is actually a very nice kit. I've completed about 5 of these so far. If you install it in a thick Picture Frame (to give it more depth) with a White translucent plastic behind the glass, it makes a nice gift. Just leave out the Switch/dc-plug and attach a usb-cable to power it. They also work really well if powered from 2 AA batteries.
I want to win I ordered this a few weeks ago.... really surprised the LED it used.... I am assuming it was regular 3 leg led's but for the price you just order it and see what shows up ... thanks for the build
how many pins are being used - i.e. what's the resistor to LED ratio? maybe its a single pin driving a single LED, although it looks like maybe 2 LED's per pin?
get a cheap USB logic analyser (well under a fiver for an 8 channel on on aliexpress) and download pulseview from the sigrok site (fully open source) and see if any signals are there. it recognises a lot of LED control pulses. I am going to do it on that laser keyfob thing you sent to see if any signal or code is being pulsed. I have already won, so will let someone else win this.
Re: reverse-engineering the code. Microcontrollers often have a protected flag that (if set) stops you from dumping out the loaded code. It may not be possible to look at the code. I want to win
I want to get into building these type of kits, but I am a total novice. How do you work out where stuff goes, if you don't get a diagram? How did you know to put that little piece of wire in between those two LEDs? I bought a clock kit from ebay. No instructions and no help from the seller. And I've searched everywhere but no luck finding anything..... Should I give up and find a different hobby? Great video's I've subscribed
I want to win! Just discovered your videos and I am currently binge watching them, haha. I'm currently at university studying Electrical and Electronic Engineering so these videos are interesting. Good content, keep it up!
I want to win The way the LEDs can be set to certain colours in the patterns does make them look like they are some sort of 2 pin controllable LED - and it also immediately reminded of Julian's Video. I'm hoping these type of LED start flooding the Chinese eBay sellers soon.
Great video again. I said I was going to sit in bed watching them :) could you put a link to that kit please I would like to build one. also I Want To Win ;)
clockwork org New ic chip arrived plugged it in and only 3 or 4 LEDs lit, unplugged it again and with the power on replaced the ic as l wiggle it different LEDs light and after unplugging and replugging several several times it began to work properly, l think if you persevere you should get it working. Good luck let us know how you get on.

+1 to stealth banana - this cheapy aliexpress logic analyzers work well - just be mindful they are not protected so if you hit voltages much higher than 5v you can release the magic smoke... an oscilloscope would be possibly best to do an initial probe - do you own one? If not maybe you could build one of the cheap kit 138 dsos which are about US16. Was good to see you in the results video - i think that kind of vid lends itself to the talking head approach Oh, and I'd like to win of course :)
I want to win Great videos btw, found your channel after seeing your response to BigClive and subscribed after watching a few of them. Keep it up, we need more channels like these :)
my microcontroller isnt working properly on mine. it just lights up the top half of the LEDs solid and the very top 2 flickers. if i place the micro controller on without pressing it in, almost all LEDs come on and try to work but just flicker and stay solid
i bought a different micro-controller and still same problem. i think it is a seat problem with the micro controllers seat. im going to try electrical grease to help make solid contacts
hi yall Did you get it to work? I bought another kit from aliexpress and it works fine, just like in the video. Thinking of switching the ic from the faulty one to the working one to see where the problem is.
i got a new and different microcontroller and it did not work still. it would try to work when i place it on gently still. i believe the problem lies with the controller bed. i removed this and going to put the capacitor and other stuff on the back of the board and then solder the micro-controller straight into the board itself. i been lazy and havent gotten to it. just only removed the micro-controller slot so far. i guess ill go ahead and work on it now and see how it goes
all of the engineering, math, mechanical tooling, software, development, skill, labor and time that went into the recipient of that chip....so we can watch lights flash...lol ...seems overkill for a flashy heart haha
Kris Cochrane I afraid that after her video you could lose half subscribers lol Title of her video - FU...K MY FINGERS ouch, on his tutorial it was so easy... I ordered NE555+CD4017 Light Water Flowing Light for her and for me (using hot air for SMD- nice video on your list) and still waiting (speedy Chinese delivery time;-) when she survive it I'll get for her something else. Heart above has amazing effect
I got the same kit on ebay (cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItemVersion&item=292042887819&view=all&tid=1424995438019), or at least it looks like the same kit, and the pics show what appear to be the same sequence of flashes and colour changing LEDs, but I'm another one who seems to have the variant where the lights fade up and fade down, rinse, repeat. Somewhat boring and a waste of the colour changing LEDS as they don't do their sequence, just 'sparkle' a wee bit (and they are the colour changing LEDS - I checked). I've looked over my soldering carefully and repositioned the microcontroller several times and used different power sources, but still fade up, fade down. Does anyone know if it's a dud microcontroller or just differently programmed, or some other problem?
I think I've narrowed it down to the two 22pF capacitors and/or the 12MHz crystal oscillator. My (very new to me; was using a very basic meter until recently) multimeter refuses to measure the capacitors properly (fine with the electrolytic capacitor; won't measure anything sensible with any ceramic capacitors - I pulled some out of another kit and had the same problem measuring those, built the kit and they're fine, so probably user error measuring those). Probed the whole circuit and finally decided the only thing not tested was the crystal. So I looked up how to measure frequency, powered on the circuit and tried testing the crystal - wildly fluctuating readings (not getting close to 12MHz) and depending on when in the fade in/fade out cycle I probe it, the LEDs either stay on steady and start the colour change sequence, or go off completely. When I've managed the steady on, the colour changes are quite nice. Given what I paid for it, I'm probably better off entering the eBay lucky dip with buying another kit than trying to source one or two itty bitty replacement parts...
Jenny Hart I've had the same problem with a number ok kits from different sellers on eBay. I've found that the problem is falsely programmed chips that are delivered with the kits. I have been able to correctly program the chips with a programmer I got on eBay. Search for article number 191796916274 on eBay. It costs around 35€. I'll keep you updated on how to fix the kits.
The code can be downloaded from this site: goughlui.com/2016/11/07/project-at89s52-based-multi-coloured-led-heart-kit/ a very interesting article about this kit. You can find a download link about 1/3 down the page. I tested it with one of my kits and it works fine.

hi K C...
nice pretty color LED heart kit...
better rather all components on the back PCB...
i have good color LED heart and star kits / projects
I want to win
I ordered this a few weeks ago.... really surprised the LED it used.... I am assuming it was regular 3 leg led's but for the price you just order it and see what shows up ... thanks for the build
I want to win!!!!
I also wonder how the colors are controlled. Clever. Enjoy your videos
Thank you. Good tutorial
Nice work again - enjoying your videos as a new fan of electronics!
Welcome to the hobby!
I want to win.
That's a nice little project kit.
Thank you I had no idea how to do this kit and this really helped 😄
That's called multiplexing. It's how LED cubes and the like work.
how many pins are being used - i.e. what's the resistor to LED ratio? maybe its a single pin driving a single LED, although it looks like maybe 2 LED's per pin?
There's 32 RGB LEDs with 32 510ohm resistors so 1:1
Great video, have ordered some kit from ail express and buying in twos so can make them with my kids keep up the good work. I want to win

I've messaged Julian to see If he can throw any light on it....hopefully he'll reply but I imagine he gets plenty of messages asking for help.
Another good vid Kris. I want to win.
David Milne I'm glad you wanted to win because you have - congratulations! (Check my latest video for details).
well done on your first 1000 subscribers

Interesting kit! Oh and I want to win ! :) Keep it up buddy
Do you programme the chip
made this heart but all mine does is twinkle on and off, any ideas?
l'm waiting for a new chip to arrive I'LL let you know if it makes any difference.
