This is odd. I found it while looking at the other USB night light options.
It plugs directly into a USB port and does the usual "licking flame" effect, albeit with a very short loop, suggesting maybe a lookup table being used for the animation. My own preference is for a more random effect where it's hard to see the loop repeat if at all.
The circuit is simple, so it would make a good base for writing your own code for a microcontroller with matching pinout. The current draw was roughly 30mA.
I specifically avoid using intrusive mid-run video adverts.

The lower one is always on. Did they use an output to control it???
Does look like a lookup table was used seem little fast on movment to be a flame effect interesting little light Clive
Wow super simple design
local dollar store even has flame effect solar garden lights.
Good luck. 👍
Combining two or more of them in a single diffusor case should get rid of the obvious repetitiveness (I doubt multiple of these lights will stay in sync over a long time).
A bit like the aquarium light I made – a pic with lookup tables and a ws2812 strip to simulate light shimmering through the water
I wonder how feasible it would be to do the flicker effect with a noise generator/sample-and-hold type of thing.
Many of these were using musical greeting card chips that the market was saturated with to produce the “flame”. By looking at it you can sometimes guess what song it is “playing”.
Would be nice if they made a version that's basically an Arduino, just plug into a PC to reprogram. (Shouldn't be too difficult to DIY.)
Not even a black blob anymore… only a 'real chip'…
Thanks for spending time with us today, Clive. Your company is always appreciated.
I spent hours recently experimenting with; orange flicker, steady orange and steady red leds.
I salvaged some garden solar lights, which are all doa, and stripped them down to the bare globe. The faceted glass globe gives a nice effect.
Best so far, 1 x 5mm red, 3mm orange, and 3mm orange flicker one.
Gets a bit crowded in there with resistors and clear heatshrink housing. 😉
Huh, a year or two ago I got a 240V version of these flame bulbs and tore it apart, found the majority was low voltage and stuck a USB lead on it.. This seems a bit easier 🙂
