Light emitting diodes. Solid state devices that provide the ubiquitous power and indicator lights on your electronic gadgetry. Unlike lamps, there are no filaments that glow. Rather, some two volts of DC power at a miniscule 10 to 20 milliamps of current get the chemistry excited, and they just plain emit. Emit is a good word, too, as they don't really cast light, but glow brightly. We have a nice assortment of 3 and 5 MM diameter sizes in red, green, orange, and yellow. The longer lead is always positive, the shorter always negative, and you always need a current limiting resistor (about 500 to 1,000 ohms for 5 to 9 volt DC sources) to keep the current in the 10-20 MA range. If that's Greek to you you're either going to blow a lot of LED's or learn to change incandescent indicator lamps ! !

They have the look of something designed for the space program. They're mylar, a paper-thin shiny metallic sheet, that comes in handy when your car breaks down in winter, or when you're separated from your climbing group on the slopes of Mt. McKinley. Barring that, they're also a perfect material for a do-it-yourself cold-climate Halloween costume-near impossible to rip by hand, but cut easily with scissors. There's no padding, so they wouldn't be too comfy on your bed, but they sure are warm. They both come folded about the size of a wallet. The Blanket is 52" x 82", the Sleeping Bag is 34" x 84".

Budding lapidarians will lap up this rock polishing kit which is so complete it even contains some rocks. The polishing tumbler has a (3) lb. ((1) qt.) fifteen sided rubber barrel and is driven by a 115 VAC motor. Overall dimensions are 6" x 6" x 7-1/2" high. In addition to the tumbler, the kit includes an assortment of jewelry findings and a detailed manual giving you easy to follow instructions. But don't think of it only as useful for jewelry making. As a hobby, our Uncle George for many years collected and polished a wide variety of rocks which he found interesting and made beautiful in and of themselves.

These liquid crystal displays are raring to go. As soon as we can get Mary Ann to stop playing with them we'll pick out (5) assorted displays for you. (She keeps zapping them with static electricity to see what pops up. Mary Ann is easily amused.) Sizes range from 1-3/16" x 2" to a few as large as 5" x 10". They're unused. Some have pin leads, some have traces right on the wafer. Either way, they're a terrific bargain.

For fun or science. And it's not actually smoke, but a fog created the same way they do for movies and heavy metal concerts. The Zero Blaster is a ray-gun-shaped, black-light-sensitive pistol that pumps out 2" to 4" dia smoke rings (rotating toroidal vortices, to be exact) that will, one after another, waft up to 12 feet away for hours of good, clean fun. Measures 9" long x 6-1/2" high. The Wizard Stick is a fog-producing wand, 10" long on a 4-5/8" x 2-1/4" base, and comes with an instruction manual for science experiments and special effects, including making wind tunnels and a vapor-ring blaster. Also good as a household draft-finder. Each takes (6) "AA" batteries, not included, and comes with a 3-ounce bottle of non-toxic fog juice, good for 25,000 smoke rings or a whole lot of fog. Better order an extra bottle of Super Zero Fluid, the replacement juice, just in case.

It's a little 2-1/2" square base with brushed-aluminum-look sides and a mirrored top, in the middle of which 3 colored LEDs flash on and off in individual and combination patterns. Makes a dandy base to show off crystal and cocktail glasses, but stick a large styrene coffee cup upside down over it and put it in a dark room and you have the world's cheapest multi-color light show. Line up a dozen or so on the front walk and you've got the world's first flashing multicolored luminaria show for party nights. You add (3) "AAA" batteries.
