Cheapest dancing flame teardown

Ғылым және технология

It's a long time since the first (expensive) Luminara style dancing-flame candles first appeared, apparently based on the patented candle effect used in the Disney haunted mansion attraction. Then the Chinese started copying them en-masse as happens, and the price came down to a more realistic level.
This unit is the cheapest I've seen, and worth getting purely for the module or for hacking with a more suitable LED colour. The Chinese manufacturers just don't seem to understand that a candle should have a golden white colour resembling an actual flame. They either fit cold-white LEDs or the classic lurid sodium yellow LEDs that used to be the closest colour before white LEDs had been invented.
In this unit they have used a phosphor based LED, but bizarrely, they've used lurid sodium yellow again when it would probably have been easier to source modern warm white ones.
The circuitry is very minimalist. Basically the LED slapped right across the button cells (which is NOT a good idea) and the classic black blob of resin covering an IC directly bonded to the PCB. That COB chip pulses a 370 ohm coil at about 8mA on a regular cycle to deflect the plastic flame's magnet.
It's a very convincing effect when set up correctly and viewed from a distance.
This unit came from a shop called Hardy's Hardware on Cathcart Road in Glasgow (Scotland). There was a single tray of them at the back of the shop.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- www.bigclive.com/coffee.htm
This also keeps the channel independent of KZread's algorithm quirks, allowing it to be a bit more dangerous and naughty.

What I'd like to see is Clive going back to his Joule Thief, and replace the 3 LR44s with a single AA cell, rectify and filter the output of a Joule Thief and use the LED to shunt regulate the voltage to approximately 3V. Basically a garden light with a flickering flame. Use a Ni-MH and a solar cell and we have -- the eternal flame that's lit even in the rain! 😮😮😊

    The non ballasted led seems like a feature instead of cost savings. The flicker thats caused by the coil being pulsed so the impedence of the batteries cause the line and the led to drop, gives it a more candle like glow. Stablizing the line with a stronger power supply may be counteractive to the look.

    Correct. I am using a 3.3'-ish voltage, a LiFePO4 battery. It went in a 2 AA battery powered Led flame candle (but more sophisticated than the above). Next to the LiFePO4 I have an empty AA shell, with a 100 ohm resistor. Now the flikker is super realistic, as the light goes out every time the coil is powered. And the duration of the LiFePO4 is nice and long (my version also has a 6 hour times, 6 hours on, 18 off). In December I will have them in operation again .. ..

    Good to know. I would have glued a 3D-printed candleholder to the bottom of that thing, with a 3xAA battery holder in it. Or attach a USB cable with one dropper diode. This thing clearly needs a resistor. Not for just the LED but for the whole thing. If you'd power this candle like any LED, with an appropriate series resistor, the LED will cap the voltage for the blob. And yes, there should indeed be a flame-coloured led in there, instead of a cold-white one.

    I have a really fascinating suggestion you could try. A home-made battery out of soldering wire. baking soda. and distilled or deionized water Make a coil-spring of soldering wire. in a small container. Best is no-flux with highest lead content you can get your hands on. Add baking soda to saturation. using distilled or deionized water (tap water CAN work but is not the best) Then charge it at about 20mA for a while. Discharge it and charge it several times. As many as you like. I recommend a low discharge rate of 5-15mA to start with. You'll see the capacity gradually increase every time. Slow charge is the way to go. You'll get the most "capacity" stored in the battery this way. Having the electrodes closer together helps with discharge current to a point. Less voltage drop. Its a lead-tin-solder alkaline battery! it really works and its super fascinating! String several together and you can run an LED for hours You can also try different electrolytes or mixtures. Baking soda is one. epsom salt is another that works. as well as Alum. You can even hook up a joule thief circuit to one to extend the runtime to even longer. and use only one cell to drive an LED for example. Or even several LED's

    I have a couple sets of three candles per set similar to this. Each set came with a remote control that lets one turn the candles on/off, set a timer for a number of hours, turn the candle effect on or off, and change the brightness. Thankfully they use AA batteries so that I may use rechargeable batteries. I'd hate to think of the waste if I was using coin cell batteries in them. Because they are remote controlled they are always using batteries unless one explicitly turns them off using the switch on the bottom. From further than a meter they look pretty good though I can hear the clicking from the plastic piece that makes the flickering hitting something. It's not loud but noticeable in a quiet room.

    Aren’t those LR44 cells nominally 1.5V apiece making the total 4.5V, again nominally? Might be worthwhile scoping the power rails. I bet they start at 4.5V and sag as the coil is pulsed. If you have a really high Z probe, looking at the coil voltage would be interesting. Alternatively, those near field phone charger toys you were playing with were terribly inefficient but a receiver circuit with a high efficiency red LED might give a nice visible indication of the pulse timing.

    I wonder what the resistance of the switch is

    Open - infinite, closed - negligible.😖

    was hoping you would put 5v to it

    Fur sure, I'd stick a small mcu on there instead, and just make use of the low cost mechanics. Imagine a room filled with these, controlled by a low cost bluetooth module... :) Go buy all the stock!

    Time for someone to delid that ASIC, bet it's similar to the solar flower one.

    I thought that the batteries put out 4.5 (3 cells)?

    They would if their internal resistance didn't limit the current.

    3xLR44 = 4,5 Volt? Oh wait... The diode limit it to 3 volt... That's almost short-circuit! A resistor would improve the lifspan.

    I guess, if you have a USB-supply, add a ' around 100 ohm' resistor and a diode that you rip out of some old electronics, you will have a working one with maybe some special effects due to extra flicker ;-) Especially if you put this just inline with the current power-input. Not worth using new components...

    Once I tried to convert Christmas led light with same 3 batteries to usb and completely burnt it. Initial idea was to 3d print a 3 battery sized stub to put it instead of battery and wire usb cable with resistor inside... And I made mistake in current limiting

    This is probably going to be me soon enough haha. I can't stand batteries and seek to convert them to USB as well.

    Don't you have a multimeter to test the frequency with you? Button cells are never a good look in my opinion

    Modifications needed USB and better LED come on get your bits out lol 1k for led 5.2 down to 3v dropper u can do it 😊or convert it to a solar garden light candle for in the window
