Got a kick out of this gem from the reddit comments: > My S2000 car alarm would be set off whenever I microwaved blueberries. Some experimentation revealed it was anything with excess water. Buying a new microwave solved the issue but I don't like thinking about how poorly shielded the old microwave was. I tried moving the for further from the kitchen or keeping the keys far away to no avail.

Why would someone microwave blueberries?

  Making sauce or heating up a muffin, I guess? Or frozen blueberries, but why would anyone buy frozen blueberries.

    why would anyone buy frozen blueberries Because 'fresh' blueberries out of seasons cost 3 times as much and taste like nothing much.

    Maybe they had the kind that grows in the wood and not in the shop? ;) When you pick berries it is normal to store them frozen to have through the winter

  They were frozen... Out of season it is the only way to buy blueberries.

  Assuming they mean the frozen, bagged ones.

I think a lot of microwave ovens are poorly shielded. I’ve seen more than one that will kill WiFi a room away, including the one in our house. As for the S2000, I guess water coincidentally changes the frequency of the leaked radio waves to match the car alarm?

  Indeed. Several years ago, I was working on a 2.4GHz device, and we noticed that occasionally, the microwave in the office kitchen would disrupt things. A quick check with a 2.4GHz band spectrum analyser showed what was going on: https://i.imgur.com/S1Luizd.jpg https://i.imgur.com/S1Luizd.jpg The company being as cheap as it was, I simply began using the microwave as a deliberate noise source for testing the device's operation under adverse conditions, placing a few mugs of water in the microwave for a few minutes, and deliberately setting my channel to collide with the microwave.

When I lived with my brother and played a lot of WoW I would get disconnected almost every night at around the same time, and usually in a Raid which was quite annoying. Eventually I tracked it down to microwave usage. Whenever the microwave was in use, I lost WiFi.

  Did your brother ever use the microwave offensively against you? https://xkcd.com/654/ https://xkcd.com/654/
