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.

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.

Same here. So, when the world is too much for us, we strap on these 3D virtual reality goggles from Velleman® Multimedia and slip our smartphone into them. Most Androids and iPhones work, as long as the screen is 3.6” to 6”. Dial up Google Earth or some similar app and fly around the world, swooping down on the Grand Canyon, the skyscrapers of Chicago, the Eiffel Tower, the Great Wall of China or the house you lived in during college--all in 3D. Goggles have 35mm lenses that adjust for up to a 95-degree field of vision and a shelf for your phone. Unit measures 7-1/2" x 4" x 4-3/4" deep with (3) adjustable head straps, a padded perimeter and a cleaning cloth. Don’t forget to peel off the film on the lenses, just like you usually do.

Hear about the antenna wedding? The ceremony was nothing special, but the reception was excellent. Same goes for this amplified HDTV digital antenna from TriQuest. It doesn’t stand on ceremony--just offers excellent reception by marrying several types of antennae. Use it with satellite or cable for the best reception of local channels. Has a 6-1/2" loop for UHF frequencies, a pair of 32" 5-draw dipoles for VHF, a 50" coax cable with a gold plated "F" connector, and an inline 25dB amplifier powered by an included 12VDC 100mA adapter. Base has a 8-3/4" x 4" footprint. Works on all TVs.

Plug this cut-diamond-shaped, white plastic speaker into your audio player, and its internal amp and 3/4” speaker will go to work. Measures approx 2” across x 1-1/4” deep not counting the standard 1/8” mini-plug. Recharges via the included USB cord. (Charge for a couple hours before using, and adjust the volume, as it’s prone to clipping.) You pick red, white or black.

These 36-Ohm ear buds have 15-foot leads, so you could practically leave your pod/pad/phone in another room, with the standard 1/8" plug at the the end that isn't in your ears. We'll send (2) pair because we know you keep losing these things or ripping the wires off (although 15-foot leads may just take care of that little wire problem).

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.

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.

This little package of take-out parts is from a marine public address system, but you don't really have to be on the water to use it. You'll get a 15K-Ohm handset mic (1/4" out) with an 11-foot cord partially coiled, an in-line level control with a telephone plug input, a mount for the mic and a 20-foot DIN-telephone plug cord.

Electronic stuff sticking out, is it? Cozy your HDTV, DVR, Blue-ray or whatever right up to the wall or cabinet with this 180-degree swiveling HDMI adapter. Maximum cable length is approx 30 feet.

Now you can share your music with your friends, Romans, countrymen, and even strangers on a train. Just plug your buds into the standard 1/8” headphone jacks and you’ll both be tuned in. Slides into a little black rubber case that has a 7/8” slip ring so you can hang it on whatever. Bonus: the bottom of the case is a touch stylus. We’ll pick one in red, black, green, blue, pink or purple.

but violets are purple. And so are these 32-Ohm earbuds with a purple inline mic on a purple 40” lead with a standard 1/8” headphone purple plug. Include (3) assorted purple covers in a super handy dandy plastic case. Get a pair for grads of NYU (home of the Fighting Violets!) or for fans of Northwestern, LSU, TCU, KSU, WIU, ECU or Furman, plus any we forgot. Purple reigns.

Or your new extremely cute little retro AM/FM radio. In cream with blue accents, it runs on (3) “AA”s, included, and has an on/off/vol knob, band-select switch, and rotary tuning knob, like radios used to and still should have. Measures 6" across x 4-1/2" tall with an integrated handle. The instructions tell you it has a suction cup on the bottom, but don’t believe everything you read.

We’re pretty sure it was furbished by RCA, since they’re the folks who are selling this refurbished indoor HDTV/VHF/UHF/FM antenna. Has dual 37”, 6-draw pivoting poles for channels 2-13 and a tilting 6-1/4" loop for channels 14-69, all of them in digital and analog up to 1080HD, on a 6-5/8" x 4" base with rubber feet, a 12-position tuning switch and 6-foot lead with an F-type COAX connector. You like free TV, right? Yeah, us too.

Indoor reception--always the safest choice. You know, in case it rains. But seriously, folks, do you love watching TV as much as we do? Pull in your stations with this refurbished passive indoor antenna from RCA. It’s passive--just like TV-watching! Has a pair of 5-draw 39" dipole antennas (or do you say antennae?), a 7" x 4" loop and a 54" cord with a coax “F” connector to hook to your TV. Base is a compact 5" x 3-1/4" x 1-1/4" so it’ll fit pretty much anywhere and won’t hog space, unlike some pets on some couches.

We’re gonna level with you. The ball point spy pens we got our hands on offer high-def video and audio recording, a 4GB micro SD card, a USB to mini-USB cable and a rechargeable lithium battery. Thing is, not all of the batteries hold their charge. Some hold for 24 hours. Others, not so much--and we tested a bunch. So here are your options: (1) buy a few, hope one has a good battery; (2) buy one and use your soldering skills to replace the battery; (3) forget about the battery and just use the 4GB micro SD card, which is worth our discounted price alone. Pen is 5-3/4” long, by the way, and fancy-looking in black and gold. Camera and mic are virtually invisible on the side opposite the pocket clip. We recommend a good 24-hour charge and formatting the SD card before embarking on your espionage mission.
