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.

Glycerine-Filled Gauge
This pressure gauge is filled with glycerine to help foil those ugly vibes and keep condensation at bay. It measures 0-200psi in 7psi increments from 0-20 then in 5psi increments from 20-200psi all on a black/green dial. Has a 1/8" NPT fitting on the back and measures 1-5/8" dia x 1" thick with the fitting extending another 3/4" out the back.

MiniMultiMeter
Our pocket-sized multimeter measures a tiny 3-5/8" x 1-3/4" x 1" thick, with a 3-1/2 digit display on a 1-1/4" x 9/16" LCD screen. Will measure up to 500VAC, 100VDC, current from 200uA up to 10A, resistance up to 2000K ohms, and will also test diodes and transistors. Comes with (2) 24" test leads and a battery to power it. Teeny price to match its size. Great for science fair projects.
