1) Barnie has caught up to CM, and is standing right next to him. I suspect this only works because of a typo.

2) If this was the normal world, they started from the North Pole, but Minecraft is flat...

3) Barnie just logged in, and is standing right next to CM or Albert, assuming that there is a typo and the last statement should have a CM in place of one of the mentions of Albert. Which Albert is swapped out determines who Barnie is standing next to.

4) Changes in elevation.

I'm just surprised I never see something this useful ever used for anything. You'd think that perpetual motion on normal ground would be used all the time.

When the bug was first discovered the carts would move diagonally and didn't always play nice with the booster glitch. As such, it wasn't really useful then.

What I made here gives a time multiplier of 25x (5^2). The vertical CCs (vCC) can be easily made even taller and more can be stacked alongside; this was just for demonstration. A 5-stack with the same width as the first row original design would give a total multiplier of (5^6 = 15,625); a set of 7x7x7 would give *7 for the first vCC, *7^7 for the first row of vCCs, and *7^(7*7) for the entire clock. (7^7*7 is about equal to 2.57*1041. I would write it out, but I would run out of characters)

Of course, with a 7x7x7 binary counter (TFFs) you would have 1.41347765 × 1073.

posted a message on For Minecart Station Builders: Compact Buttons/Lights
You have to pull the buttons/signal torches back from the face of the array by three spaces and put a row of blocks in between that can be retracted either up or down by pistons.

nope. I need the torches to be indicator lights for the buttons :tongue.gif:

Can the torches be inverted (ie, torch off = latch on)?

Build this but replace the buttons with repeaters. Now place a row of blocks so they will power these repeaters. Put your buttons and torches on this row of blocks.

Button Block 1: Looks like smooth stone. Produces power when hit.

Button Block 2: Looks like dirt/grass (grass will grow on it). Produces power when hit.

Remove all update glitches.

Actually fix the duping issues with sticky pistons so they don't need to leave blocks behind.

The redstone bugs are easy to get used to and similar to the difference between if(a=d) and if(a==d) in c, for instance. In other words, they can be annoying gotchas for newbs at times, but if you know about them you can avoid them pretty easily, or even find a way to use them.

Pistons, on the other hand, are quite buggy and could probably use a major overhaul in a few areas. This will, of course, annoy a ton of people. However, the original fixing of redstone torches way back in alpha and the removal of the cart booster are valid analogs, so it just might happen.

posted a message on Null / Invert / No-invert Cells
He his trying to recreate a component from Eloraam's redpower mod. The mod included single blocks that would allow two currents to cross each other and the lower one could power the upper one. There were/are three of these blocks:

1) The currents pass each other and the upper circuit is not impacted by the lower one --> Null cell
2) The currents pass each other and if the lower one is on, the upper one supplies power --> Non-invert cell
3) The currents pass each other and if the lower one is off, the upper one supplies power --> Invert cell

By setting up arrays of these blocks, you could create some fairly complex encoders and decoders without much difficulty, with the caveat that you have to go through a binary step between the two representations that you want.

I would note that the understanding and space required to recreate these components in vanilla minecraft render them completely useless in circuitry. However, it is an interesting exercise.

@OP: You will get much better results if you base your designs off of the bidirectional repeater.

posted a message on Ideal substitute for dirt in my trap?
You never did let that dirt block kill you, did you?
If you didn't:

There is a powered block diagonally above the piston. Remove it or its power source.

A piston can be powered by a block that is diagonally above it, but the act of powering that block does not tell the piston to update, so it won't actually extend until it receives an update from another block.

In this case, the signal from you stepping on the pressure plate causes the piston to update and extend.
When you die, the signal from the plate goes off and the piston updates again, but finds that it is still powered, so it does not retract.

When did that get nerfed? I created a mob farm based on that principle in 1.8 and it also worked in all versions of 1.9pre.

Quote from exelsisxax

You can't make an effective 3x3 floor trap. The middle block cannot be reached by pistons, so you would have to figure out something clever which would also be slow enough to escape and/or be pretty visible. Try mods.

That is not true, actually. It is just really hard to get everything to the right place without the causing the wrong piston to move. I have finished the mechanical part, but I am not 100% sure that everything works quite right yet.

The trick is to pulse the center piston (so it leaves the block behind) and then remove the block that you are using to send power to it, so you can replace it with other pistons.

posted a message on I need a redstone bridge across my tower's moat

I can sometimes sprint-jump across the moat now, but it's really too hard to do consistently. So I decided I still need a bridge.

Well if you don't mind some jumping, then it is actually quite easy.

Bridge collapsed (this is just a small section of the moat):

Bridge "extended":

Yes, or at least, I can give you the mechanical part with all of the isolated inputs. The timing (which includes partial moves in a three-piston stack) would be up to you. That said:

1) It would be incredibly expensive and include sticky pistons.
2) It would require a large underground room for the control wiring.
3) The island might not be quite wide enough for the input wiring.
4) You would have to raise the outside edge where the bridge would be.

If you are still interested I will investigate #3 and then post pictures.
