1G Logic Lab

David Johnson-Davis developed a new 1G logic lab using 1G logic elements.

The previous version of this lab used an AVR microcontroller, which made programming difficult.

The new version of the lab avoids AVR programming and uses real 1G discrete logic elements. While there is some complexity in assembling and soldering the board, this solution makes it much easier to use and gives the feeling of working with real logic elements. The 1G Lab includes 14 logic problems, including majority voting and a binary adder.

One new feature is the ability to use toggle switches instead of slide switches, making it easy to quickly switch input bits. A distinctive feature of the lab is also that its inputs and outputs are connected to external devices.
