Sun-Powered Science Projects

Exposed to light, even these small modules will power DC motors, charge batteries, or run an eye-popping science project. 92481 is 2-9/16" x 3-5/8". All are enclosed and have leads.

A Real Grabber

Okay, it isn't the cheapest magnet in the warehouse - but we dragged John's 165 lb filing cabinet around the dock with this 4-7/8" x 1" x 3/4" ceramic magnet, we're rating it conservatively at 100 lbs of pull, and we think it's a bargain. It has a 6" bracket with mounting holes on 5-1/2" centers, plus a 1/2" ID eyehook bolted into the center of it. It's all set to troll the bottom of the lake next time your filing cabinet falls overboard.

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.

Plug It In

So the puppy chewed through the phone cord? Our modular cords with connectors on each end let you replace the old one in a snap. They support (1) or (2) lines. The off-white modular base cords connect voice or data devices to a wall jack. At this price, we'd buy extra. Fido, after all, is still teething.

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.

Survival Kit

Someday when you're lost in the woods, you'll be very, very glad you ordered this compact survival kit. It's the classic camp director's whistle, raised to new heights. The 4-1/2" x 1-1/8" dia orange-plastic treasure hangs around your neck on a yellow nylon cord. On one end, the whistle. On the other, a compass. Unscrew the compass, and it reverses to a signal mirror, and reveals a 2-1/2" deep waterproof compartment for aspirin or medicinal brandy - or for the matches you're going to strike against the 3/4" long sparker. No, it's not overkill for a teacher to wear it on the playground. 'S cool.

Mini Air Compressor

Nifty device that takes maxi air and squeezes it down into a mini condition. The device is roughly 6-1/2"" long x 6" tall x 4" wide. It has a 10 ft. cord that plugs into an auto lighter socket: i.e. it runs on 12VDC @ 10 amps. Air output is via a 12" hose with a variety of valve adapters for tires, soccer balls, rubber rafts, and just dusting off the environment. Complete with a 0-250 psi gauge. Which should be plenty of pressure to explode a weak bike tire or flimsy beach ball, so please be careful!

23271 AIR COMPRESSOR, 12 VDC
$14.95 EACH
