I have roughly one zillion screwdrivers at my disposal most of the time. I’ve got a few sets of general purpose screwdrivers, many small jewelers and electronics screwdrivers, and even some nice ones attached to Swiss Army knives and Leatherman multi-tools. But the one I use most for servicing small electronics is my Technician’s Pocket Screwdriver
If you’ve ever struggled to locate the center of a circular plate or a piece of round stock using a ruler or a square, you know it can be a tricky proposition. My usual ham-fisted method involves marking the midpoint of several diameters and kind of visually averaging all those sloppy centers to get roughly in the middle of the thing. If I need more accuracy, I try to sandwich the circle between two framing squares and then draw lines between opposing corners–lines which, at least in theory, should bisect each corner at 45 degrees and intersect in the middle of the circumscribed circle. In theory.
Overall, I like the Shinwa 78610. Even though I have a decent capacitative stud finder, I often seem to end up using a 1/16″ drill to probe for studs, anyway. And if I’m looking for joists in the ceiling instead of studs in the wall, mechanical probing is pretty much my only option, because inevitably the ceilings in my homes seem to have popcorn texture which prevents the use of any kind of instrument you have to slide across the surface. So for that use alone, I’m glad I’ve got the Shinwa in my toolbox and think it’s worth the $15.
Just saw these in a magazine and, although have never tried a pair, I am intrigued. If, like me, you’ve spent a lot of time fumbling with cheap tweezers, I might humbly suggest that, like me, you will discover that a bit of extra scratch spent on a quality pair will prove well worth it. And if, like me, you’ve ever ruined a pair of nice tweezers by tossing them carelessly in your luggage, you may, like me, also be curious about these folding precision tweezers from pocketweez.com. I’m gonna spring for a pair, I think, and I’ll let you know how it works out. In the meantime, if anybody’s got any first-hand experience or opinions, kindly let us know, below!
OK, that may not be the most exciting headline I’ve ever written, and I’m not sure the exclamation point really helps all that much. But I am, personally, nonetheless very excited about cardboard bins right now, because thanks to them, for the first time in almost five years, I am no longer burdened by a giant unsorted junk parts bucket. I have tried a lot of organizational systems, over the past few years, and I’ve finally decided that bins are where it’s at. Unfortunately, professional parts bin systems are prohibitively expensive for the number I need to satisfy my organizational compulsion. But these fold-up corrugated bins I bought off Amazon only cost 69 cents apiece, including shipping. I took an old bookcase and added an extra “halfway” shelf to each level; 6″ per shelf leaves plenty of room to toss parts into the bins without wasting space. The finished unit holds ninety 4 x 4.4 x 12″ bins, which are labeled with a thermal-tape printer and arranged alphabetically. You can see the whole enchilada in my Flickr set.
