  • Well written.

    I think an important concept to introduce is Pulse Width Modulation, or PWM for short.

    Normal AC Power coming out of wall looks like a sine wave, in that it smoothly cycles between +110/240V and -110/240V. This means that 50% of the time the voltage is positive and 50% of the time the voltage is negative.

    PWM usually deals with signals which are either entirely on or off, with no transiton between them. This way, you can vary the amount of “power” delivered by varying how much of the time the signal is on and how much of the time it’s off.

    Dimmers usually modify the sine way in a way that tries to accomplish the same thing, by chopping up the signal to make the effective “on” time be shorter than 50%.

    With non-dimmable LEDs, this messes with the AC to DC circuitry in the lamp in the way slazer2au says, because the lamp doesn’t retain enough power between two on-cycles to stay on.

    Analysis complete.

    There is partial corruption in the platforms meme-templates as well as complete corruption in most of the platforms moderation mechanisms.

    Farewell, Lemmys. Your bravery is admirable, for such flawed creatures.










  • As is Denmark, but with even fewer rifles, owing to a noticeable lack of big game.

    I think it’s important to mention that, like with medical products, we don’t generally get adverts for firearms. I want to say it’s illegal, but I’m not actually sure. Regardless, the lack of advertising for weapons contributes to the absence of firearms and related items in the public consciousness. You don’t really get people over here standing around talking about guns the same way they’d talk about sports cars or tools. Guns are very much a serious topic reserved for law enforcement and military matters.


  • Wow, thanks for the reply!

    That makes a lot of sense. I was trying to work out why a sink immediately next to a corner was bad, but now I know what you mean.

    I guess it’s a bad solution to trying to work around the problem of kitchen real estate, the same way trying to use for cabinet in the corner unit for anything is almost always a bad time.
