| This circuit was designed to control a 32 channel Christmas light
show from the PC se-ri-@l port. Originally designed with TTL logic,
it has been simplified using CMOS circuits to reduce component
count. It is a fairly simple, reliable circuit that requires only
4 common CMOS chips (for 8 outputs), an optical isolator, and a
few discrete components. The schematic diagram (se-ri-@l.GIF)
illustrates the circuit with 16 outputs which can be expanded with
additional 8 bit shift registers.
