Numberabbey - 67 Early Spring by Kanddak

Map Description:

I built an eight-bit ripple-carry adder over the weekend and have just started the digging to take it up to sixteen bits.. I've seen a few theoretical designs for full adders on the wiki and such, but never a complete system.
See it in action here: http://mkv25.net/dfma/movie-1084-numberabbeydemonstration

Point of Interest: Assembly area

Here's where all the pieces of an adder get put together.
The lever by each of the lower workshops is specific to the dwarf meant to work there, so when it's time to make the pieces of another adder, the lever is ordered to be pulled and the door is locked as soon as the dwarf comes in. Then I order three mechanisms and eight floodgates. Once the floodgates are done, I unlock the door to the microcline stockpile and order two doors and two hatches.
You can't see those in this export, but they are used for a system that seals every pressure plate in the adder to store results, so that they can be transferred to one of the input rows in order to add several numbers. The microcline lever in the utility area controls this.
Once everything's done, I let the dwarves out, let the stockpiles get refilled, lock up the colored-stone-working area, and order forty mechanisms from the manager screen, to be made out of regular stone and used for linkages.

The gabbro stockpile is for making mechanisms to use for gear assemblies to distribute power to the sum display gears, which are made in batches of four each time I expand the system by four bits at which time I also need to order four doors and twenty hatch covers for the access tunnels to the north of here. - Kanddak

The next logical step is to design a Dwarf Fortress tunnel-system that will act as a computer powerful enough for you to play Dwarf Fortress!

This is very impressive. I was designing one myself but you beat me to it. Oh well. I still have a few secret projects underway.

I particularly like the compactness and effortless extension. The color-coding is a nice addition.

Holy cripes.

Do you have a video of it working? or is it just the layout proof of concept?

Submitted by: Kanddak - 2009-02-06 to 67 Early Spring

Yes KaelemGaen, the demonstration movie is here: http://mkv25.net/dfma/movie-1084-numberabbeydemonstration

*Astounded* Wow, when you first said adder in your earlier works, I had no idea you meant it literally.

I might look into trying DF computing; ideas that popped into my heard were:
- Rather then gears be the output, why not show it with water levels. Have individual one space channels that act can act as digits. It might be limited to a non-base-ten standard, but interesting to me at least.
- A veritable "Dwarven Water Clock". Imagine it, able to tell you the DF time for day, month, and year.

In your video you have eight side-by-side gear assemblies that apparently don't connect to each other - how'd you manage that? I wasn't aware that was possible o_O

Submitted by: Kanddak - 2009-02-11 to 67 Early Spring

Dakira: You might do that by having the output gears power pumps. You may be interested in my design for a 7-segment display or the associated forum discussion.

Sukasa: The output gear assemblies do connect to each other when they're engaged, but they are disengaged until the correct pressure plates are submerged.

Holy addition! can it do subtraction?

Submitted by: crash2455 - 2009-03-31 to 67 Early Spring

Binary addition is binary subtraction, it's just how you interpret the bits.

It's too bad you can't assign multiple pressure plates to set something off, or else the drawbridge seven-segment display idea wouldn't be so complicated.

Problems?

Do you only see a blank space?
