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 trouble of redesigning the microwave, you'd do a world of wonders to get rid of the magnetron altogether in exchange for a few microwave heating transistors [2]. That way, you can target hot spots better, have better power control, and generally make better food. If you're gonna remake the microwave, do the job right.

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.

Is it really that hard to push "Time cook -> 2 -> 3 -> 0 -> Start"? I mean come on I can understand wanting to optimize your life or whatever but complaining about microwave buttons seems a bit ridiculous.

For the record, many of the microwaves I've used have required something more like "Time cook -> 2 -> 2 -> 2 -> 3 -> 0 -> 0 -> 0 -> Start -> Facepalm" than the intended "Time cook -> 2 -> 3 -> 0 -> Start".

TL;DR: pressing buttons is easy, but sometimes they press your buttons back.

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

Our Emerson is awesome, you just push 2 and it runs for 2 minutes, no need for Start. Push Start alone, and it runs for 30 seconds, every push adds 30 seconds.

Haven't pushed more than two buttons in almost a year.

Ahh memories. Back in college I had a microwave where almost all of the buttons stopped working over time. Eventually I had to set everything for something like 4:44 or 44:44 and use the timer on my phone to know when to take it out.

Gold automatic mode? Sounds blingy
