Parking Meter Guts
When parking becomes so expensive that meters take an ATM card instead of a quarter, all those coin-operated meters become surplus! Now you can own the mechanism from a used POM Inc. digital meter. Measures 7" tall x 5" wide x 3-7/16" thick, with a 1-13/16" x 11/16" LCD display window on the front and a motorized 3-color window on the back. Coin-box and mount not included. Requires a 9V battery (also not included) and has a reset to the left of the coin-slot. Preset for (12) minutes per quarter and if you can find a way to change it, let us know. Perfect for charging folks to park in your driveway, and just screaming to be included in a steampunk creation.

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.

In Only
Worried about your appliances during storms? Our small, three-prong plug-in transient surge protector 1-1/2" x 1-1/4" x 1" (with no female end) plugs into a single outlet, whether on an outlet strip or an outlet receptacle. It turns the entire receptacle into a surge protector, and protects your wiring from high-voltage spikes. It works by directing the surge through itself and away from your valuables. It has an indicator LED and is fuse protected but, again, has no outlets on it. A very handy item. UL listed.

Portable Oscilloscope
The Velleman HPS10 Personal Scope isn't some graphical multimeter -- it's the complete, portable, affordable oscilloscope you've been waiting for! The 10MHz oscilloscope has an analog bandwidth of up to 2mhz. It has 5mV to 20V/div sensitivity in 12 steps, and a 200ns to 1 hour/div time base in 32 steps, full automatic setup, and 5 different trigger modes. It measures dBm, dBV, DC and rms, has signal markers for Volt and Time, and 2 memories to store signals. It has an X and Y position shift signal, DVM readout with x10 option, and audio power calculation (rms and peak). Easy to use and, with a high-contrast LCD display (128 x 64 pixels), easy to read. Accurate enough for professional use on automotive and audio equipment, digital signals and various types of sensors, but priced low enough for educational and hobby applications. Requires (5) "AA" batteries or a 9V adapter (not included).

Decibel Meter
'Tain't a toy, McGee. And 'tain't surplus. This digital dB meter from Sper Scientific is pocket-sized--8" x 1-5/8" x 7/8"--and measures sound levels from 32 to130 dB with a built-in 1/2" microphone using (2) "AAA" batteries (included). The resolution is 0.1 dB and it's accurate to within 1.5 dB. Has a built-in calibration oscillator and comes with a foam windscreen and small screwdriver for calibrating. It's very easy to use, with one-button operation on what the manufacturer calls the smallest, lightest dB meter on the market--to help you stay a step ahead of OSHA.

Meter That Volt
A nice price for a 0-10 volt DC voltmeter. The black-plastic housing is 4" x 5-1/2" x 3-3/4" high overall, with a slanted gauge face about 3-1/2" x 4". Red and black thumbscrew terminals for positive and negative inputs. Great for small school projects or testing batteries around the house.
