Measure temperatures without a touch with this digital infrared laser thermometer. Pistol style, 6" long with a 3" nose and 1.5" back-lit LCD readout. Point the guide laser where needed and measure from -58 to 716 F, and -50 to 380 C. Accurate to +/- 2 degrees C.

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 @ 3-12 VDC to the gizmo and it extracts 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. Comes with instructions. Large is 1-9/16" sq. x 3/16" thick.

Our most minimal, but still really bright gooseneck lamp is a mere 6" long in flexible rubber. Plugs into a USB outlet and has a bright COB LED on the business end. Travel essential.

This little amplified speaker looks like a mini classic guitar amp, in vintage brown and tan, with a silver grille on the front and “Mini Amp” written in a font you will recognize from your garage band days. Measures approx 4-1/2” wide x 4” high x 3” deep with a 3W speaker, on-off switch, red power light, audio input and (3) knobs for treble, bass and volume. Powered by the included USB cable or (3) “AA” batteries, which you supply. Comes with an auxiliary cable that you plug into your phone, MP3 player or tablet, since another thing you supply is the tunes. Works with PCs and Macs also . Paul from our USB Specialty Speaker department already bought one for himself, so we know it's nice.

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.

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 38" 7-draw dipoles (think: ears of a very large rabbit). Slick looking.

Teeny price to match its size. Great for science fair projects.

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 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 well-made plastic siren/whistle, a touch over 3/4" in diameter and a similar touch under 2" long, has a perforated metal disk that rotates in response to a silent blast from the perpetrator's lungs. This creates a high-pitched, loud and certainly distinctive siren-sound that picks up pitch in relation to the air velocity, sustains it as long as your wind holds out, and winds down quickly thereafter. A fine way to signal your arrival or departure. Probably not loud enough to collect the clan at the beach, but loud enough to get their attention in the classroom! The size makes it hard, but not impossible, to swallow, so please use care in teaching youngsters to sound like a miniature air raid siren.
