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: 1

Rules

All posts must be showerthoughts
The entire showerthought must be in the title
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
- If you feel strongly that you want politics back, please volunteer as a mod.

Night lights that detect light levels are probably flickering so fast that it just appears to be on (self.showerthoughts)

Ok so I got this idea not while showering, but because I'm very high. The story does come from my bathroom though! I have a night light in my bathroom, and I was looking at the night light as I turned off the bathroom light. I'm a big nerd so I remembered that the things that detect light levels are actually diodes wired in reverse. I thought it would be funny to make it flicker by reflecting the light back on the diode, but it didn't work. That's when I had this realization

You need to research how optical sensors actually work.

From this source:

A phototransistor is a type of bipolar transistor in which the base-collector junction comes into light. This results in the same behavior of a photodiode

I'm high and I just wanted to post something low effort that I thought was funny. I know it's more complex than the way I described it.

Edit: also, diodes are directional. Saying that a photodiode is "a diode wired in reverse" should be the first sign that I know more than what I'm actually saying. All diodes are capable of reacting to light, a photodiode exploits and amplifies the principle.
