I modified the design of a circuit that appeared in Modern Electronics last
year.  The magazine's design used diodes to program a matrix of five strings
of lights, and counters stepped through nine programs of flashing displays.
I thought it would make a terrific Christmas gift, but the suggested cost of
> $100 was unacceptable.  I redesigned the circuit to give either five or
seven channels (strings) of lights, and up to 16 programs, all stored in an
EPROM.  The end result was spectacular; total cost is probably around $35.
What do you think?
