How do you dispose of mechanical or electrical items that cannot be repaired? It is likely that you will send the damaged unit out to be recycled. That was what my sister-in-law did with her microwave oven. I had the same model and when mine was damaged, I kept the large ceremic plate in it and it became the best cutting board I ever have.
It will be easier for you to decide what to do with your mechanical or electrical items that cannot be repaired if you know what they are made of. I am sure that there are parts on them that you could re-use for other purposes. Most of the time I get my inspirations from Pinterest if I want to upcycle something I have in my craftwork.
Recently, someone asked on Zero Waste Facebook page how she can dispose of her damaged clock and watches. I did a search on Pinterest for "upcycle damaged watch" and I like what I saw there. I think it is a great way to keep momentos of watches you or someone in your family have been wearing throughout their life.
I will definitely hang on to the plate from my new microwave oven if it breaks down on me one day because it should work out nicely as the face for a clock one day.
I also like how watches can be remodeled to become a locket bracelet.

And as usual, there are people out there who make a living selling parts salvaged from watches and clocks. They could be purchased by watchmakers who need parts that are no longer manufactured to repair antique watches. They could also be purchased by crafters. This looks like an interesting bracelet to own.
