Right Angle Driver

Direct that power right where you want it. Inside the metal box are a couple of gears and shafts, what counts, though, is the way it lets you turn a shaft at a 90° angle, with no loss of power. 1/4" splined shaft couplings, male at one end and female at the other. 2" x 1-3/4" x 1" thick overall.

Direct To Modular

Don't toss out that obsolete direct-wire phone. It was made back in the old days, when telephones were made to last a lifetime instead of a year and a half. Use it, instead, with your modular wall jack and this 25 ft cream-colored base cord. It has a standard modular connector on one end and spade connectors on the other, and supports (1) or (2) lines. You get a working phone, and a warm feeling for saving the life of that reliable collectible.

31280 MOD/DIRECT CORD
$1.00 EACH

Mercury-Free

Fearful of language barriers, some folks get anxious when they travel internationally. Not this fine red-alcohol glass thermometer. Whether its travels take it to Britannia or Madagascar, Appalachia or Moscow, it's always ready to tell the temperature in the local tongue. Working stateside? No problem: it reads 0° to 234° F, in 2° increments. On a junket across the pond? Again, the Passport Therm shines, reading -18° to 112° C in 1° increments. It's 12" long, 3/16" dia, and travels in a nothing-special-but-still-handy plastic case.

Kaboom

One of our truly unusual treasures. It's a used 28 VDC single-pole/single-throw toggle switch, possibly military surplus. A sensor mounted on it is labeled Oxygen Warning Switch. We think that means that it switches off in the presence of pure oxygen, the better to keep from blowing something to kingdom come with an errant spark. Overall, it's 3-1/2" x 1-1/2" x 1", not counting the 3/4" toggle. The 3-pole sensor itself is under a black-painted aluminum cover 1-1/2" high x 7/8" dia. (3) leads, (3) holes in its right-angle mounting bracket. We're just not sure what it is that would be blown up if it weren't there.

LCDs

These liquid crystal displays are raring to go. As soon as we can get Mary Ann to stop playing with them we'll pick out (5) assorted displays for you. (She keeps zapping them with static electricity to see what pops up. Mary Ann is easily amused.) Sizes range from 1-3/16" x 2" to a few as large as 5" x 10". They're unused. Some have pin leads, some have traces right on the wafer. Either way, they're a terrific bargain.
