This Little Light Of Mine

Little is the operative word here. These surface-mount LEDs are perfect for hobby trains, dollhouses, even flashlights, anywhere you need tiny but bright lights. Color is white with a luminous intensity of 1000-1300 mcd (millicandelas), 2.8-3.4 volts, and a color temperature of 6500K. View angle is 140 degrees.

Jarvis Says: These require soldering so if you are not familiar with the process these are not for you.

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 at 15VDC to the gizmos and they extract 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. They come with a datasheet. 1-9/16" sq. x 3/16" thick and draws 6A.

Wire Are You Guessing?

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. Not sure how to use this gauge? Just strip a bit of wire and slide it through the gauge slots, not the holes, until you find the smallest one it'll fit through. It’s for non-ferrous metals, which is pretty much all of what you run across anyway, unless you’re Ferrous Bueller.
