Author Topic: 4 Bit Binary Adder (no events!)  (Read 1214 times)

Title says all.

I got interested in this since finding out that logic bricks existed through this thread:
http://forum.blockland.us/index.php?topic=217704.msg6199946#msg6199946

I decided to make a more compact version of it.

Since processors are made up of three fundamental gates (not, and, or) You could theoretically
make a real-deal programmable computer with no events;

on activate > pixel1 > set color (red)
on activate > pixel2 > set color (red)
on activate > pixel3 > set color (red)
on activate > pixel4 > set color (red)
on activa-


You get it.

Well, you could argue that the logic bricks and "wires" use relays, but I can't see anything in the events window.

In order to play around with it you'll need both of these mods

The adder itself:


Cover taken off:


Here the four full adders can be seen as the yellow transparent plates, covered in a stufffest of wires
The reason why they're so colorful is because that is how one wire brick is kept isolated from the other, preventing the whole circuit from "shorting" out.


Really the most difficult part was laying the wires out so that they wouldn't short out and had space.
Even then, I could not get some of the wires to fit inside, and you can see the wires that connect to the display going outside.

I think it's actually pretty cool, especially the fact that they glow when they're powered.

Note: If the adder does not show the answer on the 5 digit display, then try clicking all the print bricks first.

Also it shows in binary form, so conversion is required.. It really isn't hard though just look it up.


Awesome stuff, nice job keeping it compact.

Finally someone who realizes the potential of this and bothers to post.

Honestly, I expected some of the members of Comblock to be interested (even though the clan is dead).


Thanks, by the way.
