Possibly. Might be marking some isolation or just a stylistic choice by the designer.

My other running theory is that (due to relative proximity to audio chip), they’re muting FETs for muting audio channels when connecting headphones/speakers to prevent speaker pop.

Here’s another idea. In that image, directly below these FETs you can see the little crab logo on the chip. That’s the audio driver. It’s possible these FETs are muting FETS for the analog audio channels. Basically they hold the audio lines down while you connect/disconnect your audio devices to prevent speaker pop.

Like this:

I’ve seen some designs that use two FETs per channel which could explain why there’s so many.

Can you link that note?

I think that’s usually the method in high power applications where heat dissipation is paramount. Each of these diodes is only rated for 210mA of drain current. From a BOM cost perspective, it’d be much cheaper to just buy one 5A FET rather than parallelizing a bunch of 0.21A FETs. That 5A FET would be in a package that could handle whatever heat it generates.

From the book “Packing for Mars” by Mary Roach:

In a memoir, astronaut Michael Collins relates a story of a physician back in the Apollo era who recommended regular masturbation on long missions, lest astronauts develop prostate infections. The flight surgeon for Collins’s moon mission “decided to ignore that advice,” and ignoring seems to have been the basic approach to the human sex drive ever since. It’s the same way at the Russian space agency. Cosmonaut Alexandr Laveikin told me he too had heard that lengthy abstinence could cause prostate infections, but that the space agency pretends the issue doesn’t exist. “It’s up to yourself how you will deal with it. But everybody is doing it, everybody understands. It’s nothing. My friends ask me, ‘how are you making sex in space?’ I say, ‘By hand!’” As for the logistics: “There are possibilities. And sometimes it happens automatically while you sleep. It’s natural.” John Charles told me he’d heard about the link between prostate health and “self-stim” --at NASA, there’s an abbreviation for everything-- but never heard any formal discussion, pro or con, of orbital masturbation.

Are those near a connector (maybe on the other side?)

Could be a bunch of ESD protection diodes which only come in to play if you wear socks on carpet and touch the connector terminals.

Can you provide the numbers listed on the parts? Usually just 3 numbers/letters.

Also, looking at the circuit traces, does it look like all three terminals are connected? Is one connected to the ground plane? (The copper that covers most of the board surface around the circuit traces).

Edit: looks like they’re 2N7002 MOSFETs

These act like a digital switch that can use a small voltage to toggle a larger current. Odd to have so many, you normally wouldn’t use a bunch in parallel instead of just a larger FET.

So they look like they’re all connected to the same traces?

Ricoh GRiii. I went dumbphone two years ago and needed something quick and compact. It’s served me well.

Right. Sorry, I thought you were implying that the liquid moisture in the steam was causing the sundog. Didn’t realize it was cold enough for steam to freeze.

Rainbows due to water moisture show up when you face away from the sun. The geometry doesn’t work for when you’re facing the sun.

This is primarily a concern because extension cords aren’t fused, and there’s no control over how they are routed.

Most wiring in your walls come after a circuit breaker and are designed to allow for a certain amount of heating. The electrician follows a code that guarantees that the circuit breaker will trip before there’s any possibility of too much heat. This table indicates a higher ampacity rating for higher temperature ratings.

Now most extension cords are made cheaper by using lower gauge than the wiring in your walls. The general assumption is that they’re spread out, so the heat has no way to build up, and you won’t be plugging them permanently into something drawing the peak 15A allowed by the circuit breaker.

If you were to pile up a 100 foot extension cable and plug in a hairdryer, you’d probably start a fire. If it was all spread out, likely your hair dryer would just receive less than the 120V it’s expecting, and it wouldn’t get very hot.

Ironically, dinky christmas lights make very safe extension cords because they’re fused inside the plug.

Merry effin Christmas

I usually just give them the address 1600 Pennsylvania Ave.

I’m not so sure this logic holds with how out of hand things have gotten. I’ve got automated spam calls that ask if I’m interested, I said yes, and they hung up on me.

It’s like the spam machine got left on over the weekend or something.

Also to add, look up suicide stats in England after coal gas was replaced with natural gas. Suddenly, poison gas was less available. Not only did gas related suicides drop, all suicides drop.

No way to prove causation, but for a lot of people, the decision to kill yourself depends a lot on convenience. There isn’t a lot of planning involved.

Shotgun physics get complicated. I remember hearing a case where the gas in front of the slug (or shot or whatever) propelled the shotgun out of the victim’s mouth, and the shot ended up skimming off their face.

Leaving them disfigured but very much alive.

In any case, suicide is largely an emotional thing rather than logical. Don’t read too much into it.

But if you’re up for a dark laugh on the topic of conscientious suicide, consider https://youtu.be/snjCj0ntG8E

I mean there are a ton of efficiencies to be gained with using communal resources.

Why can’t a bunch of people share a park rather than needing their own back yard?

Not saying it shouldn’t be an option, but the American obsession with detached housing at the cost of higher density housing is a major contributor to insane housing costs.

Or public housing
