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 ! !

Yellow translucent plastic cones, 9-7/8" long OA. They were made in China to fit over a flashlight thus turning it into a warning device. They are fine for that if your flashlight has a 2-1/2" dia. business end, the ID of the large end of the cones. The small end of the cones is 7/8" dia., and may have a removable plug of the same plastic. However some of the plugs have wandered off, so the end may be open. Not into signaling?? Use them as traffic obstacles on the play lot, to mark the edge of the volleyball court at the beach, or to protect the lump on your head from rain!!

Make your portable CD player really portable: take it for a ride with these skip stabilizers. The plastic housing is full of springs that should eliminate skips on all but the worst roads. Plus, each has an adapter that connects your car's cigarette lighter with your CD player. (To hear the music, though, you'll have to order-from us, naturally-a pair of speakers for the player's headphone jacks.) The DC-DC converter by itself would be a steal at this price. Use it for your CDs, or for any small DC appliance: tape deck or perhaps a portable espresso machine? Made by Koss; (2) different ones: 5-5/8" x 6-3/8" x 1-1/4", black. #27640's output is 9VDC at 500 mA; the output plug is 5mm. #27642 is 6VDC, 500mA, with a 3.5mm plug. All (3) take the standard 12VDC input.

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.

Armed with orange-rubber squeeze bulbs, the Techie Team is blowing through the dust bunny races! Okay, it's a little exaggeration. They're not full-grown dust bunnies, they're dust specks. And the Techies are just blowing them off circuit boards, electrical contacts, and vintage Motown platters. But the 4" x 2" dia bulb with a 1/2" x 1/8" ID brass tube on the end has greater precision and a much longer shelf life than an aerosol duster, and provides more fun than they would ever have at Hialeah!
