    What if i want a Grass-Starter, or even a Water-starter? The first gym is tough with the Fire-starter.

    I’m no electrician, but attaching the hot and neutral wires of an end appliance to the opposite wires of the power supply shouldn’t be a problem on a lot of bare bone, electromechanical hardware that don’t have logic units. Please correct and enlighten me, if you’re more knowledgeable! :D

      swapping hot and neutral typically isn’t a problem - its alternating current anyway. However, most DC Appliances are sensitive to reverse polarity. Ever tried connecting a electrolytic capacitor the wrong way around? On the other hand many customer appliances have some kind of protection against reverse polarity.

      Something as simple as an incandescent light bulb works either way. LED lights are picky about electricity.

        Individual LEDs, yes; the rectifiers in most LED “bulbs” shouldn’t care.

    If you reverse the polarity of lots of things, you get a fire starter.

      …and likewise, many things stop working during a fire, making them rudimentary fire-detectors.

A “Showerthought” is a simple term used to describe the thoughts that pop into your head while you’re doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.

Here are some examples to inspire your own showerthoughts:

  • Both “200” and “160” are 2 minutes in microwave math
  • When you’re a kid, you don’t realize you’re also watching your mom and dad grow up.
  • More dreams have been destroyed by alarm clocks than anything else

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. No politics
    • If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as “capitalism” and “communism”. If you must make comparisons, you can say something is different without saying something is better/worse.
    • A good place for politics is c/politicaldiscussion
  4. Posts must be original/unique
  5. Adhere to Lemmy’s Code of Conduct and the TOS

If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.

Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.
