Lasers in Space!

Artemis II is testing an upgraded laser-based communications system called O2O >> Orion Artemis II Optical Communications System designed to send data down to Earth at up to 260 megabits per second.

O2O is about the size of a house cat and it uses more or less standard issue infrared lasers, Erbium-doped fiber amplifiers, and receivers used in the fiber telecom industry. O2O develops approx. one watt of optical power.

Artemis II also uses traditional Microwave tech as its core communications system.

Any time the microwave is running, all devices and TVs freeze.

In this day and age, is the microwave supposed to interfere with the Wi-Fi?

Reminds me of the 1970s when, on a good night, my FM radio would pick up the conversations of the air traffic controllers and pilots.

We're getting a vintage 80's #microwave oven. The #gasplasmadisplay seems to be working--unbelievably.

It's mounted inside a cabinet, so it's caseless (or could be?)

Is there anything I can do to keep it running as long as possible? EG: replace the power supply with a modern one? Replace the capacitors in general?

It's so funky, we want to keep it running. Looks like Apollo control panel designers laid it out.

@LibraryAndTea I was boiling water for ghastly tea in the hotel microwave on my most recent stay, and set fire to the cup.
(Normally we take a small kettle when we can go by car.)

Is this the end of civilisation as we pretend/know it is?

Our Samsung multi oven including microwave has put an SE (Serious Error?) up. It is about 6 months old. After following the trouble shooting guide, still getting the SE message. I had to print out my own manual when we first got it.

So have contacted Samsung to get a person rather than AI 'help desk', which is little use to anyone as we all know...

Apparently Samsung are by appointment to the King in UK. Should I also write to HH King Charles too?

It is model MC28H5013AS in case anyone is interested...

Today was going too smoothly, so I managed to *burn glass* in a microwave.

The handle of this pyrex jug (almost certainly not "real" pyrex) touched the... grille? emitter? of the magnetron and stopped turning, and there was a loud buzzing sound and bright sparks for a couple of seconds before I flew across the kitchen and hit the open button.

WTF just happened? Why did glass do this? My first thought was "oh fuck did I leave metal in there" but I absolutely didn't.
