These momentary SPST push-button switches are normally open and measure 11/16" dia x just over 3/16" thick and have a 15/32" shaft with a steel lock-washer & nut plus a pair of 1/8" solder terminals on the bottom. Rated 3A at 125VAC or 1A at 250VAC. You pick red, green or yellow.

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.

By jiminy. A little jumper cord with a modular plug on one end and flat "T" connectors on the other side at the end of dual leads. Wires are insulated, with 3-1/2" of the 7" length covered by a telephone-wire-style gray jacket.

Call it the Heart of a Doll, because that’s what it was, once upon a toy store. Today it’s a red, heart-shaped plastic thingy, 2-1/2" wide x 7/8" thick, with a smaller heart-shaped button on top. And yeah, it’s a little creepy. Hold the button and it emits a soothing electronic heartbeat at a tad under 60bpm. Runs on (2) button cell batteries, included.

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?

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.

This black aluminum heat sink measures 4" x 2" x 1-1/14" with a 2" x 2-1/4" base. (6) 5/16" thick fins at the top and a set of (5) more at the bottom above the base. In between the fins is a 1-1/4" x 2" space for your chip with a 1-1/8" square thermal pad and a 3/16" bore.

These plastic potentiometer knobs are for 6mm knurled shafts and measure 25mm across the bottom and 19mm in height and across the top. Knobs are knurled with a pointer. We’ll pick from gray and dark brown versions.

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.

Get plugged in with this pair of jacks, one each: 1/8” (3.5mm) feminine jack to 1/4” plug; and 1/4” feminine jack to 1/8” (3.5m) plug. Both are TRS--tip/ring/sleeve--wired. You get (4) jacks in all, you lucky thing, you.

More gators than a University of Florida homecoming. Scroll on down and select from: our 6-piece assortment of 2” electrical clips including (2) each of insulated pliers-type alligator clips, regular insulated alligator clips and booted alligator clips in red and black; our 29” red and black test leads with open alligator clips at the ends; or our 6-pack of plated 1-1/2” alligator test clips, half red and half black, with crimped ends.

Is it spring? Well, it’s a spring. This steel extension spring is technically a “short throttle return spring” and measures 2-1/4" long x 7/16", but it will be just as happy returning anything else if your throttle is already back where it belongs.

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.

From Therm-O-Disc, this thermal cut-off switch is N/C (normally closed) by definition. (Thermal cut-offs are what keep your coffeepot from burning your house down.) This one shuts down between 221°F (105°C) and 248°F (120°C) and measures 5/8" dia x 9/16" thick, with (2) axial terminals.

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.

Take care of your screens and they'll take care of you. (A drill sergeant told us this about our socks once, but this time it's true.) This kit includes (3) wet and (3) dry anti-static wipes, a 7" x 4-1/2" microfiber cleaning cloth, and (6) self-adhesive clear vinyl screen protectors at 3-1/2" x 2-3/4" with a grid on the back to help cut them to size, and a little plastic thingy to squoogee the air bubbles out.
