LEDs By The Dozen
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 ! !

A Window Box...
but not the kind with petunias in it. This 3-1/2" x 2-3/4" x 1-1/8" snap-hinged box has a 2-3/16" x 1-1-7/8" clear-plastic window in the lid. It's textured black with a delicate sliver-tone accent outside, removable dark-blue velvet inside. The velvet has a subtle 1-1/4" dia depression lined with a satin ribbon, a little large for a quarter but sized to hold a collectible coin. Classy looking. See Item #33991, #33992 and #33993 under Materials for classy special-occasion coins that fit into it.

Socko X-Ray Sets
Way inside? Try our assortment of human and beastie X-rays. These, from Roylco®, are very useful for biology teachers and have real possibilities for artists and designers: fold 'em into lampshades, blow them up or shrink them on a copier, or scan them and have fun in Photoshop™. The human skeletal system, a complete skeleton when assembled, is in (18) sheets. The broken set has (15) sheets of nasty human fractures, quite literally from head to foot. Actual X-rays are reprinted on transparencies which work with overhead projectors, and range from 3-3/8" x 6-7/8" to 7-1/4" x 14". They come with info sheets in English and sometimes also in French.

Patches and Badges
WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
Frankly, we don't need no patches or badges, stinkin' or otherwise. But you do. Because you have patch-mad progeny. Someday they'll get over it, but meanwhile, here are a whole big bunch of staggeringly inexpensive iron-on and self-adhesive embroidered fabric badges and patches. The large ones range from 1-1/2" x 2" up to a 2" x 4" oval in dinosaur and sports themes. The small ones are for small-fry, but are an excellent quality and very workable for scrapbooking moms. All about 1" or 2", they feature tiny houses, cars, cows, clouds, stars, that sort of thing. Very, very assorted.

Putin These On Sale
Seventy-plus years of Soviet history neatly packed into a set of (5) wooden nesting dolls, just like the chubby-mummy matryoshka, but with hammer and sickle emblems on their backs. The outer doll is a 6-1/2" tall Gorbachev, with Brezhnev, Khruschev (we think), Joe Stalin, and a tiny, 1-3/4" Vladimir Lenin all nesting inside. Recent Russian events are putin them in the surplus universe.

Harmless Jellyfish Fun
Own your very own mini-aquarium/lamp with a trio of 2" long, diving, undulating jellyfish, but without that nagging problem of death by anaphylaxis when you feed them. (Because you don't feed translucent marine invertebrates made from rubber.) They're very lifelike jellyfellas, however, cavorting for your amusement in the 9-5/8" x 7-3/8" x 2-1/2" aquarium and lit by oscillating red, blue and green LEDs. Makes a fascinating bedside night-light. (No extra charge for fascinating underwater dreams.) The adapter plugs into a standard wall outlet, and it turns itself off after (4) hours if you don't.
