Any interesting electronic projects using the entrails of
a microwave oven?

Other than trying to execute yourself? Many of the operational voltages
generated within the average home microwave oven's HV section can and have
been lethal. The microcontroller and timer circuitry may however be of some
use to an experimenter.

They aren't really a source of parts. They are fairly simple devices,
with much of their size used up in the cooking space. And what parts are
there are likely to be pretty specific, to microwave or to high voltage.
The only way you'll get much in the way of useful parts is if you are
doing something with either of those things.
VCRs are a much better source of common parts. Lots of resistors, and
capacitors. Plenty of small signal transistors. Some neat radio related
components, if that interests you. Usually some common DC motors. All the
screws you can use. They are also easier to carry home when you find them,
compared to microwave ovens.

The circular magnets from the magnetron of a microwave oven are |
very strong and I have a dozen or so with which I have performed
some interesting experiments, but I understand that the device they
are attached to contains a radioactive gas which can be a health hazard.
Perhaps someone else can confirm this.

Negative on radioactive gas inside the Mag. Again, worse problem is possible
HV stored in HV Cap that can give a very nasty shock indeed.

Am well aware of HV. (I did the jacobs ladder and telsa
coil things many years ago.)
I disassembled the oven a year ago and stuffed the
electrical parts in a box, just haven't taken the time
to do anything with them.

I have seen plans on the Web to make a welder out of
the transformer (or several transformers wired together).
The basic idea seems to be to cut off the HV secondary windings
and wind on a few turns of heavy gage wire. I think they
typically get about 4-6V per transformer this way, and add
more transformers for higher voltages.
Best regards,

There is nothing radioactive in a microwave. |
It might be an active radio, but never radio active. |

The magnets on the F-4 APQ-109 magnetron were awesome; I wish I still
had some. No gasses in the magnetrons, although I believe the trigger
klystron did contain radioactive gas. The klystron did the job of the
trigger capacitor in the typical MW oven (the power of the RADAR system
was a tad higher).
