1 wide adder - darkcrafterwiebe - 07-15-2013
Making a 1 wide adder atm but I kinda failed D: it doesn't have a carry in but does have carry out and its 2 wide because of 1 block :/ need to improve
RE: 1 wide adder - JeremyG - 07-15-2013
I've a 1-wide tileable ALU if you want to see it.
RE: 1 wide adder - Guy1234567890 - 07-16-2013
1wide O-o it would have to be a 45 degree stack or a 1 up 1 down stagger to work efficiently.

One wide adders and other circuits are usually very slow.

* newomaster might make one of these.

Haha, true. Although, they also tend to get pretty big, I'd be very surprised if you made one smaller than 90 blocks per bit. Good challenge right there.
RE: 1 wide adder - darkcrafterwiebe - 07-16-2013
Currently my adder can calculate 01 and 10
RE: 1 wide adder - CMOSprinkles - 07-16-2013
One wide tileable half adder, nice
RE: 1 wide adder - darkcrafterwiebe - 07-16-2013
nono not half, its a full adder but not tileable :p
RE: 1 wide adder - CMOSprinkles - 07-16-2013
An adder that can only calculate either the sum or the carry but not both at the same time is by definition a half adder.
RE: 1 wide adder - darkcrafterwiebe - 07-17-2013
Oh lol... I'm bad at rs ):
RE: 1 wide adder - CMOSprinkles - 07-17-2013
Hey, no problem! Making your own one wide half or full adder certainly isn't bad at redstone! Keep working on it, excited to see what you come up with
RE: 1 wide adder - darkcrafterwiebe - 07-18-2013
Gave up on it, shouldn't start with a 1 wide before I finished a normal adder :p
RE: 1 wide adder - CMOSprinkles - 07-18-2013
Haha, makes sense. Two wide adders are a lot easier to work with, I think they're a lot of fun.
RE: 1 wide adder - Billman555555 - 07-23-2013
Dcrntricts 2 wide adder can be modified to 1 wide with only 1 added
Torch delay. I reccomend starting with 4 wide adders and then going
Over to 2 and 1 wide design.
RE: 1 wide adder - redstonewarrior - 07-24-2013
Tomys/Icks/I built a 1 wide (45 degree slant, LSB low end) instant carry adder. We used glowstone, which helped with offset/ensuring no backflow. Hmmm.
* redstonewarrior considers finding that, and tomys' refined second version
RE: 1 wide adder - CMOSprinkles - 07-25-2013
If it's less than 6 ticks to output sum or carry, then that might actually be useful as a super compact adder (even if it's ripple carry)
RE: 1 wide adder - Billman555555 - 07-25-2013
Imma changing my Adder to 1-2 wide design 4 ticks sum and 2 tick
Carry in 1 bit and instant till 9 bits.(Instant 9)
RE: 1 wide adder - CMOSprinkles - 07-26-2013
So, redstonewarrior, any news on that 1 wide adder? That actually sounds pretty exciting if it really is instant-carry.
RE: 1 wide adder - redstonewarrior - 07-26-2013
Oh, yes. We didn't actually use glowstone in V1, and I don't have V2 around (that I know of.) It's somewhere at /pwarp redstonewarrior 4. ({1,2} == main plots, {3} == special project, {4} == nastalgia plot)
RE: 1 wide adder - Billman555555 - 07-26-2013
I want 2 plots now 1 for SAC and 1 for just main plot.
Anyway how is it possible to have a instacarry 1 wide adder.
Also Brits 2 wide adder is more reliable than Dcentricts.
RE: 1 wide adder - CMOSprinkles - 07-27-2013
You can use glowstone or half-slabs to prevent backflow in one wide space, and I assume he used the usual piston method from there. Although, I would still love to see the design, it would be wonderful if you could just make 1 bit of it again and take a picture redstonewarrior
