The basic foundation for all logic, these are display magnets to use as an educational aid in teaching Digital Electronics courses. These gates have spots for embedded magnets and raised characters so they can be printed without an MMU.

The posts on each end are also able to fit together to make logical chains. I will continue to develop more symbols and additional connectors so larger logic circuits can be constructed. 

The magnets used are 2mm tall, 6mm diameter neodymium magnets.
