I'm now on etsy with a little electronics parts store. As I wrote on the Genteel Recessionista's comments:
Modular income spot number 1268: Electronics components.
Think about this for a moment: an old CRT is somewhere between $50 and $free these days. These used to be $200-400. The number of components inside is between 500-1500, and these are discrete components due to the high powers in a CRT. This means that you’re getting components that were originally 14¢ each on average for a maximum of ¢10. Electronic components one-off go for somewhere north of $1 a pop, even for the smallest diode. Notice where the profit comes in? Check out my etsy store to see this in practice.
