Power Locks
We thought power corrupts, but it turns out otherwise. Power locks. You could put these in a car door, or think up something really kinetically clever. These brand new 12VDC door lock actuator assemblies draw 2.6A pushing or pulling with a 5/8" throw. Measure 4-5/8" long x 2-1/4" at the solenoid x 1-3/16" thick. Top is a removable plastic ring. Comes with 6-3/4" x 5/8" steel mounting bracket, a 9" rod and assorted screws.

The Vent-Miser
Do you dream of being an HVAC wizard? Of actually closing vents in sporadically used rooms to save heating and air conditioning dollars? Well, who doesn’t? It’s not only possible but more probable with this programmable, motorized louver cover for a heat duct. Meet the Vent-Miser™. It runs on a pair of “AAA” batteries (not included—most wizards have their own) and is programmable for (2) weekday and (2) weekend open/close cycles. Also has a manual control, low-battery icon and audible alarm. You pick from 4” x 10” ID (5-1/2” x 11-1/2” OD) in medium brown or white steel, or 4” x 12” ID (5-1/2” OD x 13-1/2” OD) in white steel. Mounting screws included.

Peltier Heat Pump
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.

Be A Meter Reader
And save a bundle. The "Kill-A-Watt" plugs into a wall outlet and accepts the power line for any devices or appliances that draw up to 1875 watts. Identifies energy eaters, tracks efficiency and costs over time, and checks on your electricity provider by monitoring voltage, current (amps), watts, kilowatt hours, frequency (Hz), volt amps, power factor, and elapsed time. Measures 5-1/8" x 2-3/8" x 1-7/16" with a 1-3/4" x 11/16" LCD screen. You may never use a waffle iron again.
