1 bit full adder (no mods) V3!

[rokit]

hi this may not intrest all of you but i managed to make a 1 bit full adder in mari0 using logic gates

it is fully expandable.

how to operate:
each button is 1 and if you press 1 button it just means 1. if you press 2 buttons it means 1+1 and if you press 3 buttons it means 1+1+1

there are cubes on the left to press multiple buttons.

screenie!
this is the tidierer version

open spoiler below to see how to operate and old version

main screenshot (labeled):

results (show older version but works the same way):

1 button (1)

2 buttons (1+1)

3 buttons (1+1+1)

how to expand:

just make another full adder next to it and instead of the carryout being a display link it up to the carry in of the second one instead of a button (all labled)

also labled all the gates if anyone is intrested.

NEXT STEP:

• MAKE IT NEATER AND NO LATENCY
• expand it and make a 7 segment display with rom instead of binary output
• make proper input (dunno the best way really)
• make it into a full 8 bit alu and make a cpu as well (would be pretty slow. only way i can think of making a clock is a goomba stepping on a button then off it.)

[TurretBot]

the buttons you use your use key for would probably be the best input,
love it so far I can't wait to see where this goes

EDIT:
would a calculator be possible?

[TheJonyMyster]

does it work if you press a different combination of buttons?
like, would pressing the second button alone show as only one?

Yes

I forget if you can capture entities with the better level editor but if you can, you should use that

nooooooooooooooo :(

aside from that,

[rokit]

would a calculator be possible?

yes that was my next planned step , problem is, i know i can use buttons that you can press by E (use rsnor latches for memory) but one thing is how will i label them and 1 more important thing that will take ages is the rom that will connect to the seven segment display. (rom will basically make somethong like 1001 into a set of links that will display a 9)

currently workin on a more compact xor gate (since every adder uses 2 and i plan on making it 4 bit [would mean the max number would be 11111 or 1111 i cant remember {since the last carry out can be used as a 10000 (in binary)}])

edit: its 1111 (15)

[TurretBot]

just do 9 check boxes in a row 1 check box for one two checks for two etc

[ucenna]

Well I decided to give the xor gate a go. I managed to make one that only took up 19 (18 if you don't include the target block, which in my case is a light bridge) blocks. I don't have time to get a screenshot up but here's the level code:

updated
nice one ucenna but ill stick to mine since i know it from memory

[ucenna]

Mine's updated as well. I managed to compress it to 14 blocks (15 with output) unless you don't mind your output being inverted then it's 13 (14).



Ignore the vertical link to the left, that's for my other model.

Edit:
Thanks, yeah they're hard enough to figure out how to make, let alone to remember.

I was too lazy to remove the other one so it's still there.

If your still trying to create rom I have a method. Turns out that minecraft-style RS latchs work. Just put a detector to not gate to laser, that triggers another detector that has a not gate that triggers a laser that activates the first detector. You'll need to add a laser on either side to activate the detector when you want to swap the rom.

hmmm
nice idea
just mad because i created a REALLY compact 1 bit full adder (could fit 2 per screen) but i mustve wired it wrong somewhere cause it didnt work. btw its: 2 xor gates 2 and gates and an or gate and looks like this:
