This module provides three logic gates that share a single input. By swapping CMOS logic chips the gates can be set up as AND, OR, XOR, NAND, NOR or XNOR. It outputs +5V gates and accepts any signal as an input. I've found it most useful when used as an AND gate, applying a clock to the common input to synchronize timing signals.

Demos, build documentation, drill guide, are available here.

Unfinished panels are drilled by hand in my garage, they are bare aluminum that may be scratched.  They are intended to be painted, etched or otherwise finished later.

Pre-Assembled Modules are built after the order comes in.  Build time can be a few days or a few weeks depending on what parts I have on hand.  When ordering, please leave a comment at checkout if you have preferences on what color(s) the panel is painted.
