Some of the food on Korea Air flights is complicated. For one of the meals I was asked if I'd had it before and when I said no I got a big leaflet with step by step instructions on how to assemble the food from the ingredients presented on the tray. That was neat, though challenging in the limited amount of space in an economy seat.
In case any of you wanted to know what infrared gas burners looks like, here's a picture. My larger roaster has two of these running down the length of the drum. They're considerably less polluting than the more common atmospheric burners, but you need to read farther ahead on your roasting plan because it takes a while between changing the burner setting and seeing the impact of that change.
The big roaster has been down (got an email when I was at ICN on my way home). After rather a lot of troubleshooting I happened to notice that the wire going to the spark plug had fallen out, which would explain why the burners weren't lighting. Part ordered. Thankfully I'm in a zone where USPS is 1 day so if that ships out tomorrow I should get it Saturday with only slightly obscene shipping costs rather than private shippers wanting more than the part itself costs for next day.
With a working CPU fan, the system runs about 20C cooler under light loads, the keyboard is no longer vibrating, and there's no buzzing sound. Those last two problems (along with the whole sometimes the fan just fails and the whole system powers down) have made it challenging to work on stuff (no new vlog episode last month because of this).
Time to roast some coffee.
New fan should be arriving tomorrow. Hopefully it's the right one (the last 2 times it was the same wrong part). It's gotten to the point that I keep a small piece of metal that's thin enough to go through the vent to give the fan a bit of a manual spin so the computer doesn't just shut itself off after a couple minutes.
