Taking apart a microwave. Fairly simple. Fairly dangerous if you just plugged it in to "See if it works" and then start taking it apart.
it's also worth the very little effort. I've taken one apart to show you what you get.
there are a few things you should know before you start.
1. Don't power up the magnetron. You will probably DIE
2. Don't use the transformer unless you know what you are doing
3. Be Safe
4.Take out any loose objects (the glass plate)
5. Have fun
The tools you will need are simple and everyone should have them.
A screwdriver and a pair of wire cutters.
It helps to have a drill with a screwdriver bit.
