Where I live, on one day in the year, people could put their bulky junk in front of their houses for it to be collected[1]. Lots and lots of radios and TVs. For my friends and me it was the yearly electronics component delivery;-). At that time the devices often had a pouch inside that contained the schematics. I learned a ton from that.
I also enjoyed the stories from Feynman how he tinkered around with radios bought at rummage sales. I think they are in "Surely You're Joking, Mr. Feynman!" but there is also a recording where he recounts those times in person[2].
