COMMUNICATIONS & ELECTRONICS

Works on all of them except the ones stuck to your eyeballs. Corrosion-Be-Gone is a gel made to remove the schmutz from all types of battery terminals, circuit boards and contacts, on everything from cars to computer boards. Our each is a 0.3 oz jar.

This rounded 2” karambit-style blade, called the Hideaway Knife, comes in a quick-release, hard shell sheath that’s olive tan to match the hand grip. Blade looks like the talon of an eagle, and you can hang it (in the sheath), around your neck (black beaded necklace included), or stuff it into your boot or pocket.

This 300 Lumen LED light is a mighty mite. Just under 4-1/2" long x 1" dia, you slide the sleeve and the beam zooms from a flood to a don't-stare-into-this focused spot. In black or gun metal anodized aluminum, it's weatherproof and shockproof with a latching button switch and a pocket clip. Depress the button halfway when it's on and it goes into a rapid-flash mode for emergency signaling. Visible for 275 meters. Five hour life with the included 1-"AA" battery and a 110K+ hour bulb life.

This nicely made 13-piece file set has a dozen diamond-encrusted files at 2, 4 and 6mm wide x 1-3/16” long with 120, 180, 300, and 400 grit surfaces. Includes a colleted 4-3/4” long aluminum handle, Go rub something the right way.

Don't toss it and buy a universal remote. (How many things are really universal, after all?) Try this jar of Keypad Fix, designed to clean and restore conductivity to the carbon on the keys and the copper PC board pads that make up the rubber-coated switches on remotes, game controllers, and security keypads. Contains enough to coat over 200 button contacts.

In 1958, Buddy Holly came out of radios like these. This retro version of the first transistor radios measures 4-1/4" x 2-1/2" x 1" in dark blue with a wire handle that doubles as an antenna. AM works better than the FM, but who listened to FM in 1958? Plenty loud (guaranteed to not fade away) with classic thumb-wheel tuning and volume. You add a pair of “AAA” batteries. To make things even more like 1958, carry the radio in your shirt pocket.

Snap this tiny JCamera onto the temple of your glasses and it's like Major Boothroyd himself sent you out to follow Auric Goldfinger. The device measures 1-1/2" long x 1/2” square, and comes with several loops for attaching it to different styles of glasses. Camera holds (100) pics or (6) 30-second videos, and the charging case can store (8000) pics and (90) videos. Has a 5MP sensor, and records in 720P at 30FPS. USB to USB-C charging cable included.

Take the party with you with this mini-disco ball. Measures approx 1-3/4" dia and has adapters that allow it to plug into your cellie! That’s right—stuck elevators, interminable car rides, boring lunches and jury duty waiting rooms are instant parties with this light! Has a clear plastic cover with a geodesic dome pattern and a voice-activated sensor. Flashing multi-colored light is 4 Watts, DC5V. Includes lightning, micro-USB and USB-C connectors. But get your own phone—we’re busy boogying, no time to talk! Oh, wait, we have to take this…

This isn't a book, but it's definitely book-ish. Looks like a leather-bound volume from the Bodleian but it's just a little wooden box, approx 8-1/2" x 5" x 2" (7" x 3-7/8" x 1-5/8" inside) that's perfect for stashing the jewels, cash, or whatever you need to stash in plain sight on the shelves.

Our each is a package of (2) steel tech rulers. One is 6” x 1/32” for the first 2-1/2” then 1/64” for the next 1/2” then 1/16” for the last 3”. The other is 150mm x 0.5mm. Both have sliding markers/pocket clips, and both have mm:inch tables on the reverse side. You’ll need excellent eyesight.

"Laser" safety lights each with super bright LEDs run by (2) "AA" batteries that you supply. It's square and has a flashing or steady LED lamp visible up to 2500 feet (distance may be exaggerated). A 2" x 2-1/2" red plastic reflecting lens covers (3) lamps. Hook it on your belt or pack with the belt clip, use the included elastic strap for arm or leg mounting, or the included aluminum flange to attach it to your bike. It's great for general use as a warning device or as an emergency signal for roadside breakdowns.

If we had a dollar for every bike light we’ve broken, lost or had stolen, we could build our own bike light factory. You never have to sweat a bike light mishap with these safety lights since they go for under 3 bucks each, batteries and all. Lights are white or red and run on (included) button cell batteries. Energy-efficient and water-resistant, with 30 lumens and (3) modes: solid, slow strobe and fast strobe. Plastic clip makes them easy to attach to clothes.

These brand-spanking new 12VDC motors are made to move automobile seats but are willing to change. They spin at approx 190 rpm, draw 1.5A no load, and stall at approx 25A. Threaded shaft is at a right angle and is 4-1/8" x 7/16". Shaft thread is non-standard, so treat it as a smooth shaft and mount pulley or gear with a setscrew. Measures 5-5/8" x 2-1/2" x 2-1/2" overall, not counting the shaft, and has power terminals opposite the gearbox with (2) 1/4" mounting holes opposite the shaft. Shaft Thread 7/16"-8 ACME thread w/M6x1 LH at end

Stocking cap, actually, or (Navy) watch cap, but the hip kids call them beanies now, so we’ll try our darnedest to stay “with it.” This black acrylic knit beanie lights up with 5 white LED's. Has a small battery holder with a little switch under the fold. Put this one size fits most hat on when you walk the dog, shovel snow or shooting hoops at night. They come with (2) CR2032 button-cell batteries that work but may need to be replaced soon. Jarvis loves you so we will include two extra sets at no charge. Now go shovel your driveway, it looks terrible.

Your laptop is tough, but like the rest of us, it appreciates a little comfort. This 11-1/2" x 15" neoprene zippered case/sleeve is uber flexible, soft and padded to protect your investment. Big enough to fit a laptop that’s 10-1/2" x 14", or maybe a smidge larger. In white, with a tasteful black border and zipper on (3) sides.

Let’s say the only way in is through the window, and the glass is really thick, and once you’re inside you’re going to have to leave a note. Wouldn’t you know it, someone came up with a gadget for that very scenario. It’s a tactical pen, 5” long x 1/2" at it's widest in black metal with a pocket clip on the cap. Always at the ready is a glass breaker tip. But unscrew the o-ring sealed cap to reveal a hidden pen with a replaceable high-volume cartridge. This is a solid piece, nice enough for the aforementioned hyper-specific mission, but also solid enough to use in self-defense (no joke). We like it as a nice pen to keep around the house, and if we ever need to get out through a window—hey, bonus.

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.

We suggest you take this one. Made as a promotional device, it never got its promo logo and the light only shines for about 30 seconds, we think to highlight the absent logo. But it kept its ability to make your tablet stand up and be seen. The stand measures approx 5" long, and the light measures about 1.5" x 1". Comes with a 3.5" stylus nestled inside to give your finger a break, and a gray velvet pouch to store it in. Runs on (3) AG-13 button cell batteries, included, and you're welcome.
