I love buying things that are broken and then fixing them. Or at least trying to 
The main thing I buy is older games consoles (Xbox, PS1/2/3 etc) as I have a bit of knowledge around what tends to go wrong with them although Iāll sometimes go for audio related stuff - tape players etc.
Iām not particularly skilled or knowledgeable when it comes to electronics. I enjoy the challenge of trying to figure out what is wrong with things though and researching solutions how to fix them.
Iāll never spend lots of money. If I release the magic smoke with something, or just cannot get it working, Iāve lost little and have usually learned something useful and had a good time in the process. Iām lucky to have space where I can keep the remains of failed attempts to use as spare parts for future projects.
When I do fix something Iāll usually either keep it to use or give it to someone I know. If something has really had very little wrong with it (for example a dvd drive belt needs replacement), Iāll sometimes sell or trade it. But making money isnāt the point.
It continues to surprise me how many people get rid of things that are ābrokenā only for there to be very little wrong with them. Todayās disposable consumer goods culture I suppose.
Is this something other people here enjoy doing? It might not be with electronics necessarily.
