The Antique Microwave Oven that's Better than Yours

Don’t forget a physical handle to pull open the door. I’d take a steam sensor as well. Thanks to Technology Connections, great channel. Convinced me to read all the fine print until I found a Breville that had it. ▶ this video

Since everyone is mentioning Technology Connections (he deserves it, great channel), I want to bring up this video: ▶ this video To me, this really shows the sad direction smart appliances have gone in. I would love to see that smart appliances would have continued to evolve in this direction. I don't like the current state of smart appliances, but going back to the absolute basic seems like an over-reaction to me.

Tangentially related, Technology Connections published an interesting video just a few days ago, "The Antique Microwave Oven that's Better than Yours": ▶ this video

Great 'Review' of an old Microwave loaded with features. ▶ this video Why can't we have nice things by default, especially with appliances like microwaves, toasters, printers...

Fun video about microwave oven now vs thirty years ago: ▶ this video "The Antique Microwave Oven that's Better than Yours" by Technology Connections

Coincidentally, technology connections just did a recent YouTube video on microwaves that might be of interest to you. ▶ this video

Technology Connections just put out a video about an old microwave that he contends has better features that most you can buy today. Also it explains how microwaves use a humidity probe to sense steam escaping from say a microwave-popcorn bag to determine when its done. ▶ this video

Espressif's ESP32 line uses an MCU IC, either sold by itself ( link ) or with flash memory and RAM ICs, all packaged together in a system-in-package footprint. (e.g. link ) There are various options for which flash and RAM ICs are packaged together, but the ESP32 die itself is very much an MCU and has only has 520 KB of SRAM. A managed switch is very computy heavy, and does usually run a microprocessor with a full RTOS, if not Linux itself, which probably costs in the mult-dollar range. It's also not something most people have at home, outside of the switch built into their router. Everything elese you mentioned usually runs on microcontrollers with under 1 MiB of RAM. For example, Infineon's CYUSB306X series ASICs for webcams come in two RAM sizes: 256 KiB or 512 KiB, despite handling gigabits per second of data, and having an MCU at all isn't even necessary. ( link ) The Pinecil's Bouffalo BL706 MCU has 123 KiB of RAM, despite being a low-volume product where design time matters more than component cost. ( link , link ) Microwave ovens are so high volume that they often don't even use packaged microcontrollers, mounting the die directly on the PCB, with an epoxy blob protecting it, and there's no way any would splurge on megabytes of SRAM. The most advanced microwave oven I've seen was from the 90's and definitely didn't splurge on an microprocessor. ( ▶ this video ) A slow MCU with external memory could run anything, like booting into linux on an AVR ( link ) but it

The popcorn button on a microwave actually does something unique, or at least it does on microwaves with a real popcorn button. I think microwave designs are only bad insofar as they have been made so cheap that the special functions have been made vastly less useful. Obligatory Technology Connections. ▶ this video

The Antique Microwave Oven that's Better than Yours [video] ▶ this video I owned one of these, it was indeed awesome. It really did cook food intelligently.

This one? ▶ this video Sharp Carousel Multiple Choice. It seems to use a moisture sensor and lookup tables to adjust cooking times and power. I was expecting something more complex!

You can't mention the Technology Connections video without linking it! ▶ this video I owned this microwave back in the day. It was awesome, but its awesomeness didn't stand out that much because we really didn't need all those different recipes -- if we had changed our habits to Microwave All The Things then it would have been more compelling, but really our use cases came down to: 1. Reheating food 2. Popcorn 3. Potatoes very rarely did we actually cook in the microwave.
