Subject: [OT] organizing/grouping transistors To save space, storage for the majority of my home stash of small signal transistors is a plastic tub. Inside are about 50 or 60 ziploc bags, each with 20 to 1000 transistors, one part number per bag, and a big label with part number and a few specs. Saving space this way wastes a lot of time eac= h time I need to find a transistor, half the time I don't even know what I have. I am thinking about using one or two of those many-drawer things to organize them. OK, how do I group the drawers? By part number seems wrong. By package is probably a good start. Then by type(BJT, JFET, MOSFET), maybe. Grouping complementary types together seems sensible. What next? Usage(RF, switching= , linear)? Voltage? Anyone been through this before and have a system that makes sense? This is just for my corner of the hobby sphere.
