There is a guy on here that uses a small Lee casting pot and I believe potassium nitrate??? to anneal cases. I've seen some pictures on here.
Basically he built a small tray that sits in the casting pot with 2 holes in a cover, it is height adjustable I think depending on the case. He drops a piece of brass into the holes, waits about 6-7 seconds and pulls the brass out.
Casting pot is 60$, some scrap metal and a drill and you could make the cover/ rack.
Then find potassium nitrate. That is the tricky part.
I couldn't find any videos. But some pictures and info are in here
