Show and tell

Schedule revision:
	We're going to bring assembly earlier
	I aspire to add something more on electronics later
	strand
	
Carry-lookahead:
	Why?  Depth, kind of a review
	Let's write out the logic for the outputs
		Unless it takes too long

The latch
	With two nor gates
	This gives us memory!
	an also work with nand (inverts S and R)
	There are a lot of types of memory!

Philosophical note on this class:
	Try to always know what you are doing!
		What forces to we manipulate?
		What sort of machine are we controlling?
		How a thing is built has a strong effect on how you use it
		Know what you have, and you don't need any instructions
	But...you're not in a computer engineering program
		Computers are too big for one person to understand
		We have to specialize to push computing forward
	So you should know the basics of how one can work
		But not worry about the actual transistor layout
		Or reasons for different sorts of doping
	If somebody asks you "how does memory work":
		"I have no idea" is unacceptable for a computer programmer
		"Here's a diagram for a basic latch" is plenty good enough
		"Sit down while I explain the history of NAND memory" is excessive
	I'm on the middle level there
		Some programmers are on the "I have no idea" level, but you can better
		If you're fascinated by this stuff:
			Finish your CS major, but take some EE at UI
			Also take physics 211 and 212, and the general chemistry series, plus calc 3
			Get a M.S. in computer engineering from UI or BSU or WSU
	Anyway, my current goal for the class is something like:
		"Show everyone that electronics are actually pretty straightforward"

Alright, back to electronics:
	Addressable LED lights:  How come they don't have more wires?
		Serial transmission and busses
	So we need:
		A clock signal (nothing happens when it's not high)
		Memory
		and and not gates
		an adder plus memory to count clock cycles
	Let's make up a diagram that theoretically works
		Not to hard, I hope

EE note:  Catalogs (maybe I'll bring the amp my brother made)
	Let's take a look at the 555 timer chip
		I hope I remember to bring one!
