HexLogic – Logic gates in a hexagon grid
- z3ugma 12y agoLooks pretty. Are there instructions anywhere? Examples provided?
- stormbrew 12y agoAgreed. I have to admit, I'm pretty lost as to what interesting things I can do with this.
- Ygg2 12y agoIt's possible to create hex shapes that flicker without power! Basically a stable loop that acts as a super-conducting loop.
- bajsejohannes 12y agoThere are instructions on the bottom of the page. The github page also has examples: https://github.com/anubiann00b/HexLogic https://github.com/anubiann00b/HexLogic
- anubiann00b 12y agoThe only way to figure it out is to mess around with it.
- kolev 12y agoPretty although unsure at this point on how practical it is, but definitely a great idea!
- klodolph 12y agoHow to make an oscillator: Create a triangle out of XOR cells. It will all be white. Put a power cell next to the triangle. A simpler oscillator consists of an XOR cell in the center, with a power cell below it, and two OR cells: one above, and one above and to the right.
- JoshTriplett 12y agoFun to play with, but I haven't yet found how to create a wire that carries a signal around a corner without introducing instability or oscillation. A series of 'or' or 'xor' gates will carry a signal from input to output, but the other two output directions from any of those gates lead to cells that feed into the previous cell, so placing either an 'or' or 'xor' there introduces feedback. The inability to change the direction of a signal makes it difficult to create non-trivial circuits. I can create an oscillator for use as a clock signal (3-on-3-off that can be disturbed into a 1-on-1-off by placing and removing an adjacent cell). The outputs of those together would produce a two-bit counter (00, 01, 10, 11), and combining those bits with logic gates would produce a 2-on-2-off oscillator or a 1-on-3-off oscillator; however, I haven't yet figured out how to bring two outputs together.
- anubiann00b 12y agoYou can switch direction. Try putting 4 xor gates in a diamond shape ;)
- anubiann00b 12y agoAlso try a "bone" shape.

- FreeFull 12y agoA big hexagon shape made out of xor gates imitates a xor gate, except that the inputs and outputs are nicely separated. You can omit the inputs as you want.
- JoshTriplett 12y agoThanks, that works perfectly. Seems to work for 'o' and '+' as well: surround anything with a hexagon of xor gates and it will behave the same on a larger scale, as long as you don't feed it signals too quickly.

- spb 12y agoInteresting, but I prefer the simpler, emergent logic of Wireworld: https://en.wikipedia.org/wiki/Wireworld https://en.wikipedia.org/wiki/Wireworld

- sand500 12y agoDidn't not already make this years ago.

- anubiann00b 12y agoYeah, that's the original. But it's a Java applet, this is a Javascipt Canvas implementation.
- c2the3rd 12y agoHas anyone managed to implement an and gate out of this? {xor, or, true} is a universal logic set, so it it theoretically possible. A not gate is easy, but the positioning of the inputs and outputs makes and gates tricky. For those who are rusty on boolean algebra or just curious: not A = A xor true A and B = ((A xor true) or (B xor true)) xor 1
- sgentle 12y agoHere's my attempt using the "ring of xor" technique posted elsewhere: https://imgur.com/xGHmN9c https://imgur.com/xGHmN9c It follows the hex structure of the other gates (inputs down and diagonally up, outputs up and diagonally down). It's got a radius 4 (the 5th blocks being the example inputs and outputs) but I think you could probably do better with some judicious bit trickery in the middle. Edit: Radius 3: https://i.imgur.com/BaI6YLj https://i.imgur.com/BaI6YLj - I wonder if 2 is possible?
