BEST SELLERS

Our 5-foot, 18 gauge, black computer power cord is grounded, with a 3-prong IEC end. IEC cords are used to connect a lot of electronic equipment, including (yes) computers, but also musical instrument amplifiers, professional audio equipment and virtually all professional video gear. It’s never a bad idea to have an extra one or two of them at the ready.

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.

These hands-free stereo headphones have a detachable mic and a one-touch phone answer button. Include (3) sizes of ear molds, a standard 3.5mm plug and a 6-foot cord. Work with phones, PCs, tablets, video games, and pretty much anything else you can plug into. We'll pick one in cerise or electric blue, and either one will make you look marvelous.

Wires are so 2019. Step up your game with these wireless Bluetooth® earbuds from Merkury Innovations. They’re black with a metal-grate design. The (3)-buttons on the power control are for adjusting volume, play/pause, and answering calls. Buds come with (3) sets of silicone tips, a 4-hour battery and a Micro USB charging cable. Ditch your wires.

Here’s something you don’t see everywhere. We have very, very, very assorted (new) blank circuit boards ranging from 6" x 6" down to 1" x 1", and we’ll send you (10) of them with our greatest intentions of giving you at least (5) different kinds. In assorted colors but mostely classic circuit-board-green-and-metallic, they were originally intended for kids’ robotic toys and games. Now you can use this dream assortment for soldering practice, one-of-a-kind art pieces, home décor (if science is your thing as much as it is ours), and probably about a hundred other things we’re not thinking of. Oooh—jewelry!

These large momentary SPDT push-button switches are rated 10A at 125/250VAC and are mounted to a 2-7/16"dia lens plate with a 1-1/8" long x 15/16 - 2 shaft that comes with a plastic washer and nut. There's also an internal 12V 3W replaceable indicator bulb. Needs 3" of rear clearance. You pick a red, green or yellow lens.

This 5-pin socket is already wired with 9" leads in black, red, white, yellow and blue to its quick-disconnect sockets, ready for your 1/4" or 7mm spade terminals. Measures 1-1/4" x 1-1/16" x 1" thick. Matches our 94746 relay.

Good things come in little packages. In this case the package is a 1-1/4" x 1-1/4" x 1/2" modulator, and the good things are a circuit board with at least a trimpot, electrolytic capacitor, assorted coils, 3-pin connector, RCA plug and (2) pop-off covers. Have a blast.

You get a 10ml syringe of white silicone heat sink compound for use as a thermal coupling for electronics. High conductivity, low bleed and stable at high temperatures. Perfect for you electronic tinkerers out there with a sinking feeling.

We haven’t seen ol’ “Barrel Jack” for years, and if you ask us, we’re better off for it. But we were thrilled when a shipment of these USB 2.0 to 1/8" barrel jack cords came in. You know barrel jacks—the kind that carry good ol’ DC energy between devices? All ol’ “Barrel Jack” did was carry bad energy between our vices. The cord is nice 2 feet long, by the way.

These on-ear wireless rechargeable bluetooth headphones aren’t before, they’re B3, which means they’re now—and the future, too. For people who don’t like cramming little buggers into their earholes, these phones have soft earpads for comfort, a solid adjustable headband, Bluetooth®, 10 hours of playback time on battery power, and great sound. They might change the way you listen to your jams. Aux cable included, plus a Micro USB cable for charging. Phones also fold for storage in the included drawstring pouch.

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.

The Beacon Bluetooth® speaker looks like a black water bottle, approx 9” tall x 2-1/2” wide, and ironically, it’s IPX6 water-resistant. Has great stereo sound quality and volume level, a 15-hour play time, and a mic for hands-free talking. It’s also shock-proof, with an attractive silicone rubber exterior. Includes a carabiner for the loop on top, and a USB cable. This is a nice piece, from SPY+. Made all bluetooth devices and Paul even gives it 10 thumbs up and he only has 9 thumbs! Works with Android and iPhones. 

Jarvis Says: Also includes a aux. headphone jack for those of us Bluetooth resistant. 

Our little solid-state buzzer is a diminutive 9/16" x 3/32" x 1-1/4" but it buzzes along at 8,000 hertz. Rated for 6VDC 20mA, but works fine with as little as 3V. Mounting brackets with holes on the back of the short sides, 4" wire leads. Lotta buzz for the buck.

Okay, they’re just strips of metal, but CJ says one of each and a grapefruit will get you at least a “C” at the science fair. The copper electrode is 100mm long x 18mm wide  x .8mm thick (3.94" x .7" x .041”). The zinc electrode is 4” long x 3/4” wide x .027” thick and stamped “ZN”. And both of them are awfully useful for crafters and jewelry makers, too.

We were told we carry our stress in our neck and shoulders, and we blamed it on our phone until we got this headset with flexible boom mic from Merkury Innovations®. It’s like those headsets that operators wear but nowhere near as dorky-looking. These are like the padded headphones the cool kids wear, with an easily bendable mic that you position. Mic is noise-reducing, too, so you’ll sound better than you ever have. Compatible with Macs and PCs, is equipped with a TRRS 3.5mm (1/8") audio output plug. Plug and play. Your neck says thanks.

Got fuses? We’ve got fuse holders. You pick: the 3” x 2-1/2” x 3/4” model, or the 3-3/16" x 3" x 1" model with stud terminals for power/ground. Both models have a common bar that connects to the hot side of the fuses for power, and both are (4)-gang blocks, with black, heavy-duty, molded-plastic, heat-resistant bases with brass clips and 8-32 nickel-plated terminal screws with combo slot/Phillips heads. For 3AG glass and ceramic fuses up to 20A.

And if so, this pressure gauge will read zero. From Paramount Supply, it has a 2-1/4" face and measures the aforementioned 0 to 60psi/0-4000kPa. Black metal housing has a white face and blue/red lettering. Also has a 1/4” male NPT fitting from the back.
