Not you, your phone. This little wireless charging disc measures 4” dia and has an LED indicator light. Includes a 3-foot USB to mini-USB to connect to a PC or adapter. Manufacturer says it will charge through most phone cases. Pat has one on his desk, and he can’t get enough of it.

Please Note: Jarvis says, check and make sure your phone is compatible with wireless charging.

Perfect for hands-on hobbyists. Foot-pedal speed controls free up your paws to do the real work. This one's for 120VAC devices, and ideal for machines using approx 200W or 1.6A or less. Measures 5" x 3" x 2-1/4" tall, with a 6-foot cord that plugs into the wall and a 2-foot grounded female plug for your sewing machine, rotary tool, scroll saw, or, if you really make a lot of banana Daiquiris, blender.

People say they just can’t help buying these 1,700 surface-mount device resistors. That’s (20) pieces each at (85) different values between 1 ohm and 10M ohms, with a 5% tolerance. Don’t even try to resist these.

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.

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.

It's the Hollywood Selfie Pole Monopod, and the name alone is making us go all soft in the middle. Starts out 8-1/2” long and extends to a very sturdy 39” with a camera thread at the end to hold the cell-phone holder. And like many people in Hollywoodland, it probably won't work as intended. The handle was meant to recharge with the included USB cord and connect to your phone with Bluetooth, however we've found that the non-replaceable batteries are mostly non-working or only hold a charge for a few minutes, like a faded actor's career. Sold for the robust stick itself because your arms aren't long enough. And you can always repurpose it for long distant tasks.

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.

To heat what is anybody's guess, but it's a U-shaped heating element, 8-3/8" x 2-5/8" x 1/4" dia with a 107 Ohm Resistance and rubber grommets above the 3/16" wide power terminals. When CJ heated it up to 120F, those grommets got gooey, so he says use lower voltage DC.

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.

Hey, DIYers—put a little light on the subject! With our assorted 12VDC infrared LED panels, you can light up, well, too many things to mention. Panels (and naturally their corresponding LED light grids), each assembly is approx 3” x 2” to 2” x 1”. Some have leads, others don’t. Some need soldering, others don’t. Some lights are white, others are amber. You’ll get what you get without throwing a fit—and then you’ll turn it into something excellent like you always do. Send us pics.

High tech comes to Am Sci & Surp!! It is here in the form of a Peltier junction, a thermo-electric device that translates electric power into heat, and perversely, into cool. Apply current at 15VDC to the gizmos and they extract thermal energy from one face, thereby cooling it. The heat is dumped onto the other face, thereby heating it. Please note: you must use a heat sink on the hot side or the junction will fry itself, since it can quickly create a 65° C temperature differential in a no load situation. Stack two, or build a cascade to increase the thermal differential created. Or run it backwards. Apply heat or cold to the relevant face and produce a current. Amazing for science projects and experiments. Practical for coffee warmers, beer coolers and mini-refrigerator or warming oven applications. They come with a datasheet. 1-9/16" sq. x 3/16" thick and draws 6A.

You have a type—we all do—and maybe we have yours, since we have (3) different types of Unitek Type-C USB adapter cables, each black and 3 feet long. Charge and sync all your Type-C connector devices quickly and safely, using just one cable. Plug in directly and stay connected at home, at work or on the road. You pick: the Type-C male to USB-A male; the Type-C to 2.0 Micro USB-B male; or the Type-C male to Type-C male.

Tired of having to hold your old, worn test leads just so to make a connection? Then it's time to upgrade your test bench. Our each is a set of (4) 36" long test leads with 16AWG wire, and booted 3/4" alligator clips on each end. You'll get (1) each in red, black, white and yellow. Also handy for hanging photos in your darkroom and laundry when you run out of clothespins.

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 digital and analog 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 or receiver and pulls in HDTV, UHF, VHF and FM up to 1080i. 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.

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.

Sometimes leather just isn’t enough. In times like those, we pack an RFID-protection rubberized case wallet like this one. Has a plastic accordion organizer inside with (6) slots for cards, and the slots easily fit multiple cards. One side of the case is ribbed, at 4-1/2” x 3” x 3/4," you can slip it easily into your pocket. Clasp is simple but effective, and easy to use with one hand. In assorted colors and finishes and we'll try to pick one that will go with something you regularly wear.

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.

These insulated connectors are made for fastening pairs of wires together. Ours are rated for up to 400v and measure 1" x 3/4" x 5/8". The ID on the wire ports is 3.6mm and the wires are clamped down by setscrews. Our each is a pack of (10). UL/CSA.
