This module provides two separate two-input logic gates and a master logic gate output fed from the output of the other two gates. By swapping what chip in the CD4000 series you use, you can have gates for AND, OR, XOR, NAND, NOR and XNOR logic functions.

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.
