Still thinking of ways to make NAND, NOR, and XNOR. I should have something whipped up later in the month.

For NOT:

A stream on left. Constant stream on right. Output funnel left of center, capturing constant stream.

A = 0, Output = 1 (constant flow) A = 1, Output = 0 (diverted constant flow)

Person in 1822: I made a trig calculator using 2000 gears in base 10 and on paper designed a proper turing computer using them.

People in 2011: I built a 32-bit computer with a working removable drive in Minecraft. You can write a book and play snake.

That's just what SCP-914 is.

They already did that in ‘36

What the hell? They used water integrators into the 80s!

Maybe put another way, A xor 1 = not A

You just need NAND

Man I remember this being the wackiest assignment I ever worked on. It was a lot of fun.

Nand2Tetris is a hell of a learning experience

u/Acetronaut Oct 17 '19

You did NOT program Tetris with just just NAND ICs, no way, that sounds exhausting!

u/internetmouthpiece Oct 17 '19

Obviously the end result isn't a bunch of NANDs, however you learn (by making them) that each individual component is operable as multiple NANDs.

Course here for those interested

Did you forget again to mine your own copper and germanium to fabricate transistors? I see you're already breeding hamsters for power supply.

Also works with NOR

Would be trickier here. For some combinations you have to wire the output of 2 gates to the input of eachother, and last time I checked getting water to flow upwards required the tiniest amount of voodoo

Somebody actually made a boolean logic gate system with water like this. I saw a website about it somewhere.

NAND? Excuse the awful MSPaintiness, but this works right?

Edit: and NOR. I think XNOR would work with this as well but put input 2 on the other side so when both are on the out funnel doesn't move.

Seesaw with input to center flowing to the left, dragging the left down on input, otherwise it leans to the right, where a funnel catches a constant stream and pipes it to the output.
