I just finished putting this latest prototype together. It is a lighthouse controller circuit made with four CD4000 ICs; two CD4017 counters, single CD4027 JK-flip-flop and CD4093 Schmitt trigger NAND. And a lot of diodes!

The light pattern can be changed with 16 DIP switches. Currently it just flashes an LED but I might add some kind of driver for driving a small incandescent bulb. It would also be nice to have a dark-activated switch in the circuit.
