Ten electrical leads with an alligator clip on each end. Each lead is about 20" long, not counting the 'gators. Vinyl coated 20-22 ga. wire with a vinyl cover over each clip. They come in an assortment of five colors with two leads in each color. The manufacturer calls them heavy duty but we would restrict them to the light currents and low voltages you will be using in your home experiments. Our each is a set of (10).

Great for roboticists, too. It's a mighty-mite, this little 6VDC 45 RPM motor with a right-angle gearbox. Draws 13mA, no load, and stalls at 120mA. Output is through (2) double-flattened 1/4" dia x 3/16" long shafts on opposite sides of the white plastic housing, both with 1/16" dia center holes. Measures 1-7/8" x 7/8" overall. Gear ratio is 228:1.

This small reversible DC motor from JEI runs on 3-6VDC. At 6V it draws 350mA no load and stalls at 1.9A. Spins approx 1000 rpm and approx half that at 3V. Great for science fairs, hobbies and any kind of project that needs spinning. Measures 1-3/16" long x 7/8" dia with a 1/4" x 1/16" shaft and tiny contacts for power that you'd best solder.

Rated for 10A at 250VAC, these normally closed thermal fuses will pop at 128ºC or 262ºF. The fuses themselves are 1/2" long but yours will be wired into leads of assorted lengths, because they were betooken out of coffeemakers of some sort. Never been popped, though, because then they would be useless and who'd buy 'em?

This 3-phase brushless 12VDC motor from Nidec draws 2.5A max through the red and black leads with what we think are coil taps, and Hall effect outputs through the other (4) leads. Measures 36mm (1.4") dia x 40mm (1.6") long with a 4mm (0.16") dia x 19mm (0.75") shaft with a removable cam. Includes a spec sheet.

This little aluminum heat sink measures 1" square x 5/8" with (4) 5/8" tall fins and a threaded 3/32" bore.

This small 24-tooth pulley is 1-1/16" long with 5/16" of that being a 5/8" dia shaft with a 1/2" x 3/8" flattened bore. The pulley portion is 1" OD x 7/8" ID. In shiny silver aluminum.

Our motorman, CJ, called this reversible 12-24VDC motor strange, mostly because it has the power contacts mounted on the face, bracketing the 11/16" x 1/8" mostly striated shaft, and has no mounting brackets. But that shouldn't stop a clever person like you. (Hint: it was probably made to fit into a sleeve of some sort.) At 12VDC, draws 100mA no load, stalls 850mA and spins approx 900 rpm; at 24VDC, draws 150mA, stalls 2.2A and spins approx 1800 rpm.  Measures 2-1/4" x 1-13/32" dia.

In the universe of reed switches, we're assured that this one is quite snazzy. In a 1" x 9/16" x 3/8" housing with a  3/8" mounting wing with (2) 3/32" mounting holes. Trigger distance is approx 1" regardless of magnet strength. Comes with 20" tinned leads. Rated for 400mA at 24VDC. Normally open.

Don't wait or it'll all be gone. You get (4) pieces, 11 feet each, of 18-2 wire, polarized, black with a white stripe and eminently discardable spade-push terminals on both ends. (That's under a nickel a foot, cowboy.) Lamp cord, speaker wire, pretty much anything you run juice to.

Once up on a time, when giants stalked the earth and there was no night baseball in Wrigley Field, car phones were the cuttingest-edgiest technology on the planet. Guess who has the antennas. These are passive antennas, 23-1/2" long x 1/16" dia on 1" dia (suctionless) rubber cups.with 5/16" dia copper discs  inside. Perfect for giant insect sculptures or for gluing on your trunk and pretending it's 1983 all over again.

With this 1.2K OHM 10% tolerance power resistor. Rated 3 to 5 watts, it has a ceramic block body 3/8" sq x 1-1/2" long with wire leads on ends, one of which is 1/2" long and the other 1-1/2". Any questions?

Build your own quartz antenna. These (2) 4-3/8" x 3" x 1-5/16" plastic boxes each have (2) boxes of quartz crystals inside and (2) aluminum U-brackets that are attached to a single screw terminal on one short side of the box. Back in the early 70's, they were originally made to be used in pairs as part of a 300 Ohm antenna. Not sure if they will work with today's TV's but all you need is cabling to connect them and give it a try. Made in Brazil, the antenna capital of South America, probably.

These pillow block bearings have 13-gauge steel mounting straps, 4" long x 1-1/8" with 5/16" x 5/8" mounting slots, and a sintered iron ball unit measuring 1-11/16" dia with either a 5/8” ID or 1” ID brass sleeve. The 5/8” ID one has an oil cup on the top; the 1” dia version has a grease fitting in the same place.

This pair of 3” pliers-style alligator clips for quick wire connections have red and black insulator boots, and are good for up to a whopping 30A. Crimp connections are under the rubber insulators. We'll send you (2) pairs because you can't charge a battery without (4) clips. 

Little takeout 3-6VDC Mabuchi motors (6VDC nominal) spin approx 4000 rpm and draw 50mA no load. Stall at 300mA and measure 1-1/2" long x 1-1/16" dia with a 1/2” long x 3/32” dia shaft with a 2-sheave 9/16” dia pulley. Sheaves are 1/16” ID. Wired with 2” leads (positive and negative) for super easy battery or wall adapter hook up. A little dusty but incredible for scout projects, classroom robotics projects or making your own army of walking zombies.

Wire we selling perfectly ordinary, standard, all-purpose 20-gauge steel wire? Lots of reasons. One, because it's steel. Two, because it's a steal. Three, because you need to wire stuff. Crafts, gardening, general binding--oh, the wiring possibilities are nearly endless. You'll get (20) feet per each bundle.

Our each is a 56" length of paired blue and red 18AWG wire with 1/4" quick-disconnect terminals on one end and a 3mm center-to-center polarized plug at the other. Also handy as a hook-up wire.
