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 ! !

LCDs
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.

You Say Breadboad...
And the manufacturer, Elenco Electronics, says Bredblox, but what’s in a name? These are just nice little breadboards for electronic experiments. The Elenco Model 9830 measures 6-1/2" long x 2-1/8" wide x 5/16" thick with (2) power busses up both long edges and (63) double rows of more busses. The holes for components and jumper wires are approx .050" each and multiple boards can be interlocked via tabs and ports on the long edges. Now go invent something and get rich.
