I'm a pack rat. When something breaks, I strip off the useless plastic casings, put all the hardware in a bin, all the circuit boards in my overflowing e-waste pile, and all the mechanical bits in bins to be (ab)used later.
This is a running list of all the things the hoard has provided to prevent countless trips and orders from Home Depot, Fastenal, McMaster Carr, Digikey, Amazon, eBay, and a thousand other niche retailers.
