I am trained as an electronic repair technician but have been working the last three years on developing a small farm, which fortunately my region is comming into the growing season so I am predicting an abundance in the next few months.
If for some reason my crops fail my plan is to get involved in repairing, repurposing and recycling of consumer items. I might even learn how to thread a sewing machine as I believe these skills are always in demand, especially in times of a depressed market.
Edit
My city has a electronics reuse center in it where people bring old or slightly damaged consumer products to divert them from the landfill, these items are sold a fraction of their value(just enough to support the program) and this is a great source for my side income.
