Most renowned ones are most likely Air Wick ones. There are additionally others the end there choose Coleman for example.

I ultimately disassembled one to check it out.

These candles have actually color an altering LEDs in the bottom. This tiny thing which brings a romantic setting can also bring “second hand” delight to rip that apart and also discover parts and make something useful. As whatever with LEDs /electronics inside.

Findings and how color transforming candles work?

The candle has a little electronic device in the base that is turn on through the infrared light (IR) given off by the candle when burning. Girlfriend can suggest a TV far to it and cause it come come on together well. In ~ first, I believed it’s a casual photoresistor. Ns was wrong.

I to be expecting RGB LED but it to be actually different LED elements with a different color for RGB. It was powered through 2 tiny 3V batteries (CR2032).

I have an idea come hook it up with bigger RGB brought about drive it v this tiny chip. Would be straightforward to use “logic chip”- rather of using Arduino or such.

Now the image of the disassembly

Let’s view what contents can we can uncover inside. The very first step is come dig v candle wax.
