> 1. Put phone on 2.4ghz wifi (5GHZ WILL NOT WORK!) Might be nice to expand on "will not work". Wouldn't 5 GHz Wi-Fi failing to connect show that it's even better at blocking, and would easily block 2.45 GHz too? And I'd think that they should block 5 GHz too, since those meshes look quite fine, and they probably try to be extra-safe.

This thing is totally insane. Instructions are not clear at all and the risk that someone bakes a phone in a MWO or doesn't any other harmful thing is rather high. Please remove this post.

So hard not to automatically press start.

But one could also use fridge for this test.

I remain in awe that we trust the very cheapest plastic under repeat load and thermal cycling to form a -40dB seal, turning 700W into 70mW. Also, it seems that the outer metal shell of the device forms an active part of the circuit, so if it isn't plugged into a grounded outlet it sits at lethal potential. Then there is beryllium oxide in the thing...

I kind of doubt an independent inventor could bring this to market with today's startup climate.

I strongly disagree. If you are idiot enough to microwave your own phone, that's on you. This post is fine, and interesting.

Idk if OP is the person who wrote this, but on my device the red text about not turning the microwave on is not especially legible. I’d probably make that text a bit bigger and/or brighter. I expect most HN readers will know not to microwave a phone but you’d be surprised what people might do.

Indeed, it's generally not considered legible on any common devices: WCAG suggests to ensure suitable perceived contrast ratios [1], and there are checkers around [2], while this page's #f00 on #36393F is far from meeting those.

For the safety's sake, might be nice to also recommend to unplug the microwave oven altogether as the first step.

5GHz actually has worse penetration and stronger attenuation over distance than 2.4GHz. Succesfully blocking 5GHz does not imply the same for 2.4GHz. However I do agree that it's probably still gonna work because the faraday cages on microwaves are always overkill (even the cheap ones).

a cheap consumer RF meter detects "high" levels of RF from 5+ feet away, at least on the 4 or 5 random units I've tried. So the faraday cage doesn't seem to be doing its job in full.

I don't know, I'm not sure the fridge would give a good indication of the microwave's leakiness.

You need a basic level of competence to be allowed in the kitchen. - That is where most domestic accidents happen.

Funny how kitchen stuff was thought to be women's work once.
