Our each is a dozen nickel-plated 2” long steel alligator clips with PVC sleeves but no boots because they’re made for electrical testing or soldering. You’ll get (6) each with red and black sleeves.

This little 1.5-3VDC motor draws just 15mA no load, which means it's just the ticket for solar-cell applications. At 3VDC it spins approx 600 rpm and stalls at 125mA. Measures 1-1/8" long x 15/16" dia with a 5/16" long x 1/16" dia shaft and 3-1/2" leads.

Save thousands on security with this bogus camera. A blinking red light adds the right touch of verisimilitude for your average, easy-to-dupe miscreant. Extremely genuine-looking, the blinking red LED is surrounded by (18) phony white LEDs all in a 5-1/2" long x 2-3/4" barrel that connects to a stand with a useless but actual wire housing.Tilts from perpendicular to 140 degrees. Includes mounting screws, but you add (2) "AAA" batteries for the red light.

Our pocket-sized multimeter measures a tiny 3-5/8" x 1-3/4" x 1" thick, with a 3-1/2 digit display on a 1-1/4" x 9/16" LCD screen. Will measure up to 500VAC, 100VDC, current from 200uA up to 10A, resistance up to 2000K ohms, and will also test diodes and transistors. Comes with (2) 24" test leads and a battery to power it. Teeny price to match its size. Great for science fair projects.

Attention robotics boffins: Here's a nice, powerful 12-24VDC Mabuchi brush motor with a gearbox and pulley attached. At its nominal 24DC, it spins 45rpm, draws 280mA no load, and stalls a 750mA. 7.5 in-lbs of torque and is rated for continuous duty. Has a 3/4" long x 5/16" flattened shaft with a 4-5/8" dia x 5/16" wide (3/16" ID) single-sheave pulley attached, with a matching O-ring. The gearbox measures 2-3/4" x 3" x 9-1/16". The motor measures 1-1/16"dia x 1-5/8" long and comes with 7" leads and a 2-pin Molex connector.

Go digital without paying the cable guy. This refurbished digital amplified indoor antenna from RCA features a switchable inline amp with a 55dB boost and a pair of 7-draw dipoles (think: ears of a very large rabbit). Slick looking. Measures 8-3/8" tall x 4-5/8" x 4-1/8" before extension. The only cable you’ll ever need is the 6-foot coax from the unit to the TV.

We all screen. And we all need to protect those screens on our expensive little gadgetry. Our each is a pack of (12) clear screen protectors, each a generous 2-15/16" x 2-1/4" x .004" thick. They protect from scratches and reduce glare. Made for the Sony Clié, but easy to cut to fit anything with a screen you want to protect. Made in the USA for Fellowes®.

Nice little pulley unit kit includes (1) pulley each at 50, 30, 25 and 20mm and (3) pulleys at 11mm, plus myriad bushings, a 3VDC motor, (2) belts and a belt guide, base, mounts and assorted hardware. Includes graphic assembly instructions, plus a couple of rudimentary drawings with suggested projects. It's a mechanical science project waiting for a home.

Our each is a pack of (10) common cathode 5mm dia red/green/blue LEDs. Clear lens, 20mA rated for 100K hour life. 3V supply will work for all. You also get 100 Ohm and 510 Ohm resistors to step down 5 and 12VDC respectively. Luminous intensity is 4,000 mcd.

This 3-5/16” dia double-sided wire gauge wheel measures from 0-36 AWG on one face and from .005" to .325" on the other. It’s for non-ferrous metals, which is pretty much all of what you run across anyway, unless you’re Ferrous Bueller.

This torquey take-out 6-24VDC (12VDC nominal) motor draws approx 250mA no load, stalls at 7.2A and spins approx 5700 rpm. Measures 2" x 1-13/32" with a 3/4" x 1/8" flattened shaft and may have a setscrew-mounted coupler that resembles a router bit. Has prewired leads. Mabuchi part no. RS-545SH.

So you like Nickel-Metal Hydride rechargeable battery bargains? You choose a 4-pack of "AA" 2600 MAH or "AAA" 1000 MAH NiMH batteries, the recommended choice for electronics, cameras, games, cordless phones and toys.

The manufacturer, Elenco Electronics, says Bredblox, but what's in a name? This is just a nice little breadboard for electronic experiments. The Elenco Model 9830 measures 6-1/2" long x 2-1/8" wide x 5/16" thick with (2) power busses up both long edges and (63) double rows of more busses. The holes for components and jumper wires are approx .050" each and multiple boards can be interlocked via tabs and ports on the long edges. Now go invent something and get rich.

This tiny servo motor can swing approx 90 degrees in either direction via any of the (3) included servo horns with screws on the 3/16" toothed shaft: a 13/16" long single horn, a 1-5/8" long double horn or the 1-5/8" long double horn with (2) smaller cross horns. Draws between 220 and 650mA at 5VDC, and is rated for 25 oz/in of torque. Measures 7/8" x 1/2" x 1-1/16" deep with a pair of mounting wings with 1/16" bores. Wiring is 5V to red, ground to brown and timing pulses to orange. Use any 1-2ms pulses at 50Hz.

Like blue jeans, but for wires. So you can color-code those wires instead of getting all confused. You get a 10-pack of 12" long x 9/32" pieces of heat-shrink tubing, (3) each of white and red, (4) of black. Rated for up to 600V 125°C. UL.

And save a bundle. The "Kill-A-Watt" plugs into a wall outlet and accepts the power line for any devices or appliances that draw up to 1875 watts. Identifies energy eaters, tracks efficiency and costs over time, and checks on your electricity provider by monitoring voltage, current (amps), watts, kilowatt hours, frequency (Hz), volt amps, power factor, and elapsed time. Measures 5-1/8" x 2-3/8" x 1-7/16" with a 1-3/4" x 11/16" LCD screen. You may never use a waffle iron again.

It will if you buy this unused take-out sound device and speaker. Includes a printed circuit board and a 2” 1/4W speaker mounted inside a 2-1/4” square x 1-1/16” gray plastic box. Includes a (3) “AA” battery box (empty) and power switch on one pair of leads, and a photocell in a brass tube on another because it’s motion sensitive. The sound is officially a dinosaur growl, although some folks here maintain it is quite distinctly a dino belch. A dyspeptic dinosaur is an angry dinosaur, we always say, so it’s a fine line. Check out our Facebook post to hear it in action.

Break free of cables with this passive RCA HDTV antenna that’s so thin it virtually disappears. Made to receive free HD/VHF/UHF signals, the antenna is a pair of extremely thin black plastic wings, each 14” long x 3” tapering to 3/8”. Overall, it’s 29” long x approx nothing deep. The center connector has a 50” length of thin COAX cable with an “F” connector to mate with the TV input. Marked refurbished, but you can’t tell them from new. A little assembly is required.
