            "O.K., let's figure out how one is able to count in binary. Ready students? Let's zero in on our lesson for today!"

Lesson Plan: August 23, 2000....The J-K Flipflop and Quad Nand Gate.

see Kit, below.

Those little digital displays are everywhere! How many of us know how they work? Open up your mind as I attempt to dissect this little counter that flashes a "0" and a "1". This is our lesson for August 23, 2000. The students are looking forward to a day at the beach, but counters must come first (Number One)! The sparks will fly, but they must begin their computer circuitry classes. (The Los Angeles Sparks have already flown, thanks to the Houston Comets. Alas, no basketball game fundraiser this Saturday for the Tutoring Service).

Our Electronics Laboratory.

It's not much, but it serves our purpose well. There is a Logic Probe, a Clamp-on Ammeter, Digital Volt-Ohm-Ammeters, Electronics Kits ( rear: do you see the "0" that is visible? The display is counting in binary; the oscillatory output of Nand Gates is being fed into a J-K Flip Flop: The output of the Flip-Flop is being fed to the display digits: the two segments on the right ("one") are always visible, but the outer segments to the left  are being turned on and off according to the output of the flip-flop: the center segment is not connected.), Continuity Checker, Soldering Irons and associated tools, Pliers, Cutters, Strippers, and a large variety of Integrated Circuit components (quite costly). We have 2 Electronics Kits that cost us well over $300. Thanks to you, Gardner Beale D.D.S. We have been able to build this Laboratory. These are very valuable tools that will be used to teach the students all about electronics, electricity and computers.
