Discrete NAND - 4.5 ways

00:39:49

Constructing NAND gates from discrete components to explore the different design choices you might make when thinking in Electron Flow (- to +) instead of Conventional Current Flow (+ to -). 

Top Left: NAND in Conventional Current Flow (CCF) using NPN transistors, layout chosen to mirror Electron Flow circuit in top right. 

Top Right: Electron Flow (EF) NAND gate using PNP transistors. 

Bottom Left: NAND gate from diagram I found online, using magical buttons and grounds instead of completed circuit.

Bottom Right: Same NAND design as bottom left, but with completed circuit instead of magical grounds & bottons. 

Middle: [Failed] experiment to see if you could abstract out the 3 resistors in parallel to 1 in series, doesn't work in this case for NAND.

needs a lot of rework to be an error free demonstration of NAND gates. Some are not even NAND and needs redesign
