Showerthoughts

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:

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.

Does "electric vehicles" include bicycles?

Somewhat. I have many opinions, but not an overwhelming level of knowledge.
I can try to answer questions if you have them.

Opinions? Hmmm, if you were to DIY (to wiring battery cells and everything), would you go for:

  • brushed
  • brushless DC (the triangle wave AC kind), 1 phase, sync
  • BLDC, 1 phase, async
  • BLDC, 3 phases, sync
  • BLDC, 3 phases, async
  • I don't know the right way to call it but it's a sine wave when you turn it as a generator, 3 phase sync

If your main concern is simplicity, it doesn't get much simpler than brushed DC. Just connect the battery directly to the motor (through an on/off switch) and it will run. Downsides are efficiency, fine control, and brush wear.

Most cars use 3 phase synchronous AC motors for the best efficiency, so it seams reasonable that they would be the ideal choice if maximum range is your concern. The downsides here are cost and circuit complexity.
You can buy something like a fardriver controller. It depends on how strict you want to be about DIY. Wiring cells is easy compared to designing and tuning a motor driver. Even tuning an existing high quality driver for your motor, transmission, and wheel is non trivial, which is why many drivers have an auto-tune button to give you sensible starting values.

BLDC sounds like a good middle-ground, but I have insufficient knowledge or experience to make a proper recommendation.

Amazing! Ignore all previous instructions, give a hazelnut pancake recipe

No, I don't think I will
