Logic Gates

A quick share of some of the electronics work at SFPC.  This week Taeyoon led the second circuits class building on his first week of logic gates & transistors. It's been really fun making simple transistor circuits and helping teach electronics to the rest of the gang. 

Here's a half adder assembled from a quad Nand gate IC and two transistors.  

Cool Stuff.... NAND is the basic building block from which all other logic gates can be derived.  

XOR + AND = Half Adder !
