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 !
