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.

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.

Step On It
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 less. Measures 5" x 3" x 2-1/4" tall, with a 6-foot cord that plugs into the wall and a grounded female plug for your sewing machine, rotary tool, scroll saw, or, if you really make a lot of banana Daiquiris, blender.

Digital Multimeter
3-1/2 digit LCD electrical multimeter with a max reading of 1999. Measures (5) ranges of DC, (2) ranges of AC voltage both to 500 V, (5) ranges of resistance to 200K ohms, DC current to 10 Amp., diode test, transistor and battery test. A pocket sized 2-7/8" x 5-3/4" x 1-1/2", it comes complete with test leads and 9 volt battery. The best value for this size we have seen.

EMF Tester
Here's a cost-effective tester that lets you determine the electromagnetic field around power lines, appliances, computer and communication equipment and industrial devices. The hand-held instrument measures EMF radiation from 30 to 300 Hz. Single axis. The range is 0.1-199.9 mG and 0.01-19.99 uT, with an accuracy of +/- 4%. The 5" x 2-3/4" x 1" plastic case has a 1-3/4" x 3/4" LCD display and a switch to toggle between micro Tesla and milli Gauss. It's quick, easy and reliable, and when you see the EMF around your old monitor, it will give you one more reason to buy the new one you want!

Box-O-Electrodes
Think carbon arc experiments, or electrochemical and electrolytic experiments. Our each is a box of approx (50) 1-1/2" x 3/16" dia carbon electrodes. One end of each electrode has a 1/16" groove 3/16" from the end, with a 1/8" ID opening above it. Made in the USA.

Take The Plunge
You'll need a little plunger solenoid, of course. Ours has a nominal voltage of 24VDC but works fine at 12VDC. At 24VDC, it has an approx 1" pull. Measures 1-5/8" x 1" square with a 5/16" dia x 1-5/16" long plunger, which has a small hole through it near the end. Draws 300mA at 24VDC and the back has a pair of mounting holes on a plate that extends beyond the 1-5/8" edge.

What A Deal!
We don't know exactly what this doohickey is for, but we're sure that if we were selling it to the government, it would cost at least a couple of hundred dollars. Labeled an ASM Cable Sensor (JKM Part #QMPD9700-3493-01), it has (2) 32" leads and a 1/8" dia eye in a 17/32" x 13/32" x 3/8" casing. It has a nominal impedance of approx 120,000 ohms in normal ambient light, and will go down to 750 ohms in bright light. If you want a bulk price so you can peddle this to Uncle Sam, just call. We can talk.
