Minecraft Memory

Okay, this place needs some real content, so… here’s two kinds of memory I built in Minecraft.

Piston-based memory

This is a byte of readable memory with the ability to increase its value by one on request. Each byte is stored as a stack of gold/glass, the position of which determines its current value. A toggle signal (coming from the right) checks if it’s set or clear and triggers one of the pistons depending on the state, toggling it. If it’s switched from 1 to 0, the trigger signal is sent on to the next bit in line, and so on.

All 8 bits. The yellow line of wool in the distance sends a clock pulse to make the byte continuously increase by one.

For good measure, a piston-powered display unit which – due to my poor planning – has the LSB to the left and the MSB to the right. Oops. The switch to the left switches between normal and overclocked which doubles the clock pulse frequency. All in all, the system completely lacks redstone torches (except as a source of constant power) as they burn out when used in this high-frequency system.

Repeater-based memory

Now here’s a major kludge, basically thrown together as a proof-of-concept. It stores bytes as a loop of 8 repeaters, making the individual bits fly around in a circle. The entire system is thus based on timing. The large triangle at the bottom is used to generate an 8-tick pulse (which I’m technically misusing here out of laziness as its input is more than one tick long) used for operations that affect all 8 bits of the two registers.

The loop in the lower right defines the constant value 1 and thus, in theory, the timing of the system. The loop to the left of it is the A register. The gold block makes sure that the data is retained. Triggering the piston for 8 ticks will break the circuit and clear the byte. At the top of the loop, where the other gold block doesn’t complete a circuit, is the input for the constant 1, allowing one to OR the register with 1 if the piston is activated for 8 ticks. (Hardly useful, I know, but proof-of-concept, remember?)

A shot of the essentially identical B register. Also visible to the right of it is two lines of repeaters in opposite directions. By completing those circuits for 8 ticks, one can transmit the data from one register into the other, ORing them. By first clearing the target register, it simply works as a normal copy.

There’s currently no way of outputting the values, mostly because I haven’t had time to make such a system yet.

Pistons are used for changing the state of the system as redstone torches again are too slow to handle the high update frequency.

Encounter at Farpoint

Cue a 10 minute scene of flying around the website and watching it from various angles with reaction shots of me spliced in.

So, this is Tubecloggers. It’s… uglier than I expected. Now, the time travelers from the future who look through the archive will have no idea what I’m talking about as the site will most likely be beautiful in the prosperous future I’m sure they’re from. Rest assured that when this post was written, this site was… ugh.

What was I talking about?

Oh yeah. Uh. I’m Smallhacker. It’s my job to clog your tubes with random nonsense and rants in the hope of reaching internet celebrity. Yep. I’m going to become the next… uh… (insert person who got famous through blogging). Wait, do such people even exist? Uh. I dunno? Let’s pretend that there is one… and let’s call him Bob. Yep. I’m going to be the next Bob. Yeah. Can’t wait.

This is going to be awesome.

First!

So yeah, I’ve had this domain for quite a while now. Smallhacker and I wanted to set up a bloggish site together a long time ago, but it never really got anywhere. Now, we decided to give it another go using WordPress. We still have a lot of stuff to set up, though, like a proper theme.

In case you might be wondering what kind of content you’ll see here, I can tell you that we don’t really know, either. Most likely, we will post about computers, technology, programming, rants, personal endeavors and other random (un)creative things.

See you around.
