On Friday, the science project of an 11 year old resulted in the evacuation of a middle school. A 2 liter bottle with "wires sticking out"? It must be a bomb! Hackaday (a nerd blog) has a great editorial on the misgivings of people seeing home made electronics.
Sadly, these responses don't seem limited to just electronics anymore. Any number of backyard projects insight an odd mix of fear and anger - line drying of clothes, making your own soap or laundry detergent, home construction projects / DIY jobs, backyard gardens, the list goes on.
At what point did we as a society decide that it must be purchased at the store to be acceptable?
Sad, so very sad.
