I've always put my (dumb, wired) keyboards in the dishwasher and they have always come out great. I'm a statistic of one, though. I don't know if I just got lucky.
Are they dumb? Isn't there a microprocessor in every keyboard?

Electric showers are very common in the UK - although the heater is in a wall-mounted unit, with the head on a hose, rather than the heater being in the head itself. The heating element has three layers - innermost, a wire that gets hot. Around that, a ceramic insulator. And outermost, a metal cover to protect the ceramic insulator. Then the heating element is mounted in a small water tank. And that, along with some…
A lot of things involving electricity in places with type-G plugs seem more dangerous if you don't know/assume that almost everything is grounded. Took me a while to realize that hairdrier he mentioned in the blogpost likely didn't have a ground connection in the plug. In the case of a toaster with a grounded frame, the most likely route for a short is straight to earth which will trip the RCD on that set of plugs.
Also, as I assume others have pointed out, modern toasters are both electrical and electronic devices; I expect they wouldn't handle the dishwasher quite as well as older ones did.
Generally though, 100% on board with the author's point about strident repetition of common "wisdom".
On a related note, I wonder if people around the world are familiar with electric showers. Essentially, it's a resistance similar to the one found in a toaster, placed right inside the showerhead. It heats the water as it flows through. People hearing about it for the first time are usually shocked that we don't die from electrecution.
I still wonder how electrocution is not a big issue. My local electricity codes say absolutely no electricity within zone 0. I get a bit nervous about hooking up IP 65 rated lights to a IP X4 rated switchbox a meter away from the shower head

You can also just have a spoon in the microwave too, right? I think It's only from things like crinkles in aluminium foil and the prongs of a fork that produce sparks and arcing inside.
ElectroBOOM did a video testing that, and he came to a similar conclusion: https://www.youtube.com/watch?v=OyTmJX_TC84
I really like this article because it shows someone who keeps pushing their 'when to exit loop' training and the positive and negative implications of that.

Please, please, clarify this bit for me. > All that day, kids got to see Mr. Stillwater’s hair dryer running under water in a fish tank. I thought I knew about electricity and water, but what I possessed was Conventional Ignorance posing as Conventional Wisdom. Humbling. Should I put the wifes running hairdryer into our fishtank to entertain our child?
No; the author made a number of reasoning errors throughout the article. """Underwriters Laboratories modified its marking requirements for hair dryers after the CPSC brought to UL's attention reports of injuries and deaths attributed to consumer misuse of hair dryers. Under the modified requirements, hair dryers must be permanently. marked "Danqer-- Electrocution possible if used or dropped in tub. Unplug after usin…
Assuming that the dryer continues to run, it is perfectly safe to keep it running indefinitely in a fish tanks (without fish, of course). You just have to unplug it before removing it.
It's always interesting to me to see what you can get away with washing/getting wet without ruining it. I bought a bunch of vinyl 45's off of eBay several years ago and they were pretty gross. I stumbled across a forum where someone recommended washing them with water and a little bit of dish soap. As you can probably imagine, a lot of people freaked out in the responses and said it was a terrible idea. I gave it a w…
Nice. Once, just for fun, I followed online advice and cleaned a record with wood glue. It takes some time to dry, but it’s really fun, and the record was _spotless_ afterwards.
I was once involved in a similar (unintentional) experiment with a multi-billion dollar defence radar. A several metres deep underground bunker, containing several 19" racks full of electrical/electronic gear, filled to ground level with a combination of mineralised surface water and mud during a storm. What we wanted to do was cut the power, pump the water out of the bunker ASAP and immediately clean the whole lot w…
I wonder although wasteful, isn't this better than accelerated failures taking the defense radar offline at random times in the future? Reminds me of a friend of mine who somehow blew a shift in his car and did something bad to his engine. Instead of pulling over and stopping, he just drove it home and ended up destroying the engine. So he got a whole new engine instead of having insurance pay to dismantle the engine…
Unless an attack was underway that the radar was tracking, the right course of action was to power it off immediately, and start cleaning it. After the cleaning, it would go online promptly, and then parts of it could be assessed for damage, taken offline when the replacement is ready, and replaced, likely without even stopping the operation.
This kind of paralysis and fear of making decisions, especially when time is of essence, would be exactly what I'd like to instill in my enemies.
