Linux on a microwave feels a lot like the NetBSD toaster from all those years ago. Additionally, it doesn't make sense from a technical perspective. People have converted toaster ovens to do smd reflow with an arduino [1], and that requires a lot more delicate control of temperature and timing; hell, Linux is worse for the job because its realtime capabilities are so poor. Also, if you're going to go through the trou…

Hi! Maybe you know of any oven that is using [2] or similar? I would like to buy one. Thank you.

That was the bigger wishlist item, because there aren't any out there at the moment. Unfortunately, the kitchen appliance biz is really conservative in this sector, and even with NXP having introduced the transistors a few years ago, there still aren't any on the consumer market. Freescale showed off the Sage last July [1] to try to encourage companies to move away from magnetrons, but unfortunately, everything on the market at the moment is still oldschool.

It doesn't look there are any available, although there are a multitude of press releases from the last couple of years [0]. [0] https://www.google.com/search?q=solid+state+microwave+oven

There are some fascinating things you could do with one of those. You could, for example, make a "stick boiler"—like a "stick blender"—that you stick inside a cup of liquid to heat it up, without any part of the stick itself getting hot. (Presumably there'd be a waffle-grid cross-guard to block reflected RF.) But, in the wrong hands, that's a directed-energy weapon, isn't it? (Hell, stick one of these in the right ki…

You can do plenty of damage with a normal microwave oven in the wrong hands, I remember reading a book from the library a few years back that detailed making an EMP from one.

Thinking of that book, I don't think it's likely that libraries would carry that kind of book any more, sadly.

Can anyone here explain to me why microwave ovens always have their power settings as multiples of some value, e.g. 200/400/800w but never have the ability to set a specific power output, e.g. 425w.

I bought a "crappy" brand microwave because it has a great UI: One knob with rotary encoder for time (turn faster for minutes). One knob with rotary encoder for power. Both settingscan be changed even while microwave is running.

That's the standard interface for microwaves for me.

My standard interface is a finicky touchpad. Has been for ~30 years & half a dozen microwaves.

In japan at least most microwaves have au automatic mode that stops heating usually at the right time.

Gold automatic mode? Sounds blingy

You're an awful person. /s ;)

I only upvoted because I felt smart for recognizing "au". (Not a high-school graduate.)

That's a fine looking death machine there. Then again, the buttons on my microwave are also so horrible I've been tempted... If he gets the voice control worked out to where I can say "Tea, Earl Grey, Hot" I might be sold.

That's what the original microwave UI was like:

Mine is like that too, and it works really well and simple to use compared to the alternative of a dozen not-very-tactile buttons. It's based on a mechanical timer, so no buggy firmware either.
