Candle technology hasn't changed much in thousands of years: add fire to a wax-soaked wick and provide light for hours. It is simple, effective and does not require an update. So, of course, someone on the internet has spent three years redesigning the candle from scratch with digital guts, while managing to preserve its old-school usability.
To be honest with Keith of Keith's Garage Test, he hasn't spent all the time of the vigil for the past three years obsessively engineered and perfected his candle. It was a low priority project that would occasionally resume when he needed a fun distraction. Having said that, the attention to detail and the realistic functionality of the digital candle are a testament to how long it took.
Powered by an Arduino The Mini Mini hidden inside a glass container and disguised with real wax, uses six independent LEDs randomized so that they flicker and randomly adjust their brightness up and down. The overall effect is that of a real bouncing flame.
This was the easiest part, however, as there are no scarce credible LED candles on the market right now. Keith took a couple of steps further, first adding a carefully calibrated infrared sensor that could detect the presence of a lit match when placed inside the candle, allowing the LEDs to be lit in the same way as you lit a real one. candle. But the best feature is a fiberglass wick soaked in vegetable glycerine that produces a quick puff of smoke when you hoe it with a few volts. It is activated by a microphone that detects when someone is blowing on the candle, so not only do the LEDs go out, but the candle also produces a satisfying trail of thin smoke that moves away.
It is excessive, yes, and excessive for the sole to see if it were possible. But if you want to add some atmosphere to your home, without the risk of burning it on the floor, this is essentially the vaping of candles, which allows you to get the correction to improve your mood.
