hello all,

in a recent move, (from my former estate) i found a bunch of
stuff i got from a radio shack "store cleaning" deal. alot of it is
leds and such, but i have several ic chips and was wanting to hear if
anyone is familiar with them and if so, could suggest some projects
for them. i am just gonna list what i have. if i have excess and
someone needs one, drop me a line. will gladly drop it in the mail.

8 74HCT163 presettable synchronous 4 bit binary counter
3 74HCT161 "
"
1 74HCT164 8-bit serial in/ parallel-out shift register
2 74HCT08 quad 2-input and gate
2 74HCT14 Hex inverting schmitt trigger
2 74HCT132 quad 2-input nand schmitt trigger
3 74HCT32 quad 2-input or gate
3 74HCT123 dual retriggerable monostable multivibrator with reset
1 74HCT138 3-8 line decoder/demultiplexer; inverting
1 74HCT00 quad2-input nand gate
4 74HCT02 quad 2-input nor gate

now, i am about to "wow" you out of the chair. i am limited in
the tech department (shameful, isn't it?) will entertain any use.
paperweight, neat christmas decorations, wind
chimes.....................

tnx and 73 mike.

these are interesting chips, and they can be configured as
programmable dividers. first hook up a small oscillator using one of
the 74hc132. make sure that it oscillates at just about 1 hz or so. u
can hook up one of the several LEDs to watch it flash. then connect it
to the 74hc163 to see it count (you can see it using the LEDs).

once you have understood how the 74hc163 works, then you can drive it
with a higher frequency source (like a VCO). If you can get your hands
on 74hc74, you can hook up a phase-frequency detector too. read up the
chapter on oscillators in EMRFD to get a full-fledged PLL going. It is
educative, fun and also very useful thing to have around.
