I pulled apart a microwave a couple of years ago so I could build a spot welder using the transformer, so naturally I also pulled apart the magnetron. The only thing I saved from that was the heatsink plates and this ring of brass wire mesh, just because it was interesting and I liked it.
Well, I thought I'd try using it to clean the really tough crud off my soldering iron tip, and it works really well! Going to make a little turntable for it to fix to the top of the iron's station
Nifty idea.
I did something similar, a blade welder for my bandswa, but I never got it to work satifactory.
At the risk of sounding like a lurker, I'll just say that the ceramic ends of the magnetron contain beryllium which is very nasty, dont breath the dust if you break it.
The "matt gizmo" is part of a magnetron from a microwave oven - not something you can buy. Most definitely do not substitute a Brillo pad, they are made of steel wool which is very abrasive and will destroy your bit.
Edit: Having said that, normal steel wool is manufactured as a form of swarf - long strips of shaved off metal with sharp edges. "Brillo" may be made differently since it is for household use.
I was inspired to try it from having seen brass wool tip cleaners you can buy, such as the ones from Xytronic.
Alt-63. One of the few things I never knew I missed about Windows...
Simpler than keeping in memory, is looking at an ASCII table. (When started to use a PC, keyboards here had no "Ñ" or "ñ") so I got used to the table thing.
But very recently, when looking for the euro symbol had to go further: Alt 0128 (do not omit the zero). €
Funny thing was that the MPLAB IDE in one of its version couldn't handle our accents and that "ñ" (to comment code). Every time you reopened a project that text was a mess.
Babel was the last oportunity and it went seriously wrong!!!
