Nuts & Volts - April 2005

reached the level of care needed to refrain from destroying delicate electronic components.

Rule 6: Store scrounged parts so that they can be found again. There is no use spending an hour or so unscrewing and desoldering parts and accessories from PCBs and the like if you can’t find them when you need them. To explain this further, if you put all of your parts into a big cardboard box, along with a mass of wires, you are wasting your time. Ensure that parts are stored in labeled containers (preferably stack-able parts drawers, available quite inexpensively from hardware stores), so that they can be found with a quick glance. You can store them along with your purchased parts, of course, so label drawers with names like “resistors,” “diodes,” “relays,” and the like.

I consider this process follow-up. You get to know where your parts are, so you can find them in a matter of seconds, rather than a matter of terse hours. Also, storing parts in a neat and clean fashion has advantages other than easy recollection; it makes your garage or workshop look a lot neater, while keeping the “other half” happy.

I hope that you will take these few simple rules into mind next time you drag home for stripping your next dump-found broken appliance. They will make your life so much easier, I assure you, and you will save a lot of money. It may be easier to remember the quick version of the rules: safety, rarity, quality, wick, diversity, and storage.

Scrounging is a hobby in itself, but you should scrounge only for what you’ll really use. Please keep in mind that safety always comes first. Nothing is so important that you should take unnecessary risks. If you have any further questions or comments on this article, feel free to email me at justfordantheman@tel stra.com I will usually reply within a day or two, if I’m not busy scrounging! NV
