I cleaned out the "misc." compartment of my backpack. I found sunglasses, spare Hagoromo Chalk, a pocket calculator, a patch cable, a coax cable, some banana plugs, allogator clips, raw copper PCBs, various BNC to SMA adapters, ferrite and iron powder cores, 4 HF transistors, a set of precision screwdrivers, batteries, a green laser pointer, a VNA and a Geiger counter. After some deliberation, I've decided that they are all essential.
