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 ! !

Surpie Stuff
If you’re a surplus groupie, if you think Jarvis sits at the right hand of St. Peter, if you can see our initials without tittering, you should be flaunting your devotion – drinking out of our white, 11 oz coffee mug and wearing our soft sweatshirts and T-shirts, all with the likeness of Jarvis (our flying mascot), our corporate name and our inspiring tag line, “Incredible Stuff, Unbelievable Prices” in black across the back and “American Science & Surplus” in small print on the left front. We have thoughtfully ordered the shirts in gray, the best color to wear when digging for surplus treasure. The T-shirts are 98% cotton, and will shrink. The sweatshirts run small, and will shrink, also. Order accordingly. Don’t just sit there – Jarvisize your wardrobe.
