モールス信号は長点と短点の連続で情報を伝達する方法です。短点は短いレッドストーン信号、長点は長いレッドストーン信号です。長点は単点の約3倍の長さです。Minecraftでは情報伝達の必要は特にないですが、面白い実験ができます。

前提知識[]

Minecraftでモールス信号を送信するには、レッドストーン回路が必要になります。信号をデコードするにはANDゲートとNORゲートの2つを使用します。まずはこれらを理解する方が良いでしょう。これらには3つの構造に分かれていて、信号を作る送信部、信号をデコードする変換部、変換されたものからライトを点滅させる出力部になります。

入力部[]

これは3つの構造の中でも最もシンプルなもので、のちに長点と短点にデコードできるようにしなければなりません。そのためには、長点を短点よりも長く入力できるようにしなければならないです。これを実現するためには、パルス回路を使用しますが、レッドストーンリピーターを使用することで簡単に作成することができます。レッドストーンリピーターには遅延機能があるので、メッセージが送られる時間を長くすることができます。

。この構造は長点と、この後に作成するリセット構造で使用します。短点は延長されていないかで検出するため、遅延や延長の必要はありません。

The Decoder[]

Now, after the 'Sender', this is going to be much more complicated. What you want to be able to do here is a system to be able to understand the dots and the dashes and convert that into a light display. To explain this, it's best if just explain from the image.

Monostable Circuit/Pulse Lengthener (long)

Here you can see one section of the decoding system. The initial decoder doesn't require the first AND gate and instead comes straight from the input 'I'. When the first input comes through it will be sent into a length detecting and gate 'B' or the repeater and gate, if the signal is long enough it will be able to pass through this and gate and then power the rs-nor 'C', which will then allow the Q for dash to be on. If the length of the signal is not long enough to pass through 'B' it will then not activate the Rs-nor, instead it will just go where the signal also goes which is round to the next 'C^', rs-nor which once switched will send a signal round to 'B' therefore not allowing any more signals to pass through. When this happens the power from the 3rd input of the 3 input 'and' gate 'B' will go to the Q(dot). If the power for the dash is on then it will over ride the dot turning it off, if it's on otherwise if the dash had been activated and then the signal goes through the dot would also be on, so you will need to make the dot turn off when dash is on, you can do this as shown, feeding the power back into the Q dot.

You will notice that at 'B' there is four repeaters delaying the message to the 3rd input this is because you need to allow time, if it’s there, for the dash to pass through and then block the gate so it can no longer be affected by any other impulse. The rs-nor 'C^' which activates the 3rd input also goes into another and gate which when the next impulse comes through will allow the signal to pass and go the same process again as before.

That about does it for the decoder.

To build the reseter, you need to just place redstone torches under all the rs-nors and then have a repeater 'and' gate the requires more than a dash would and set up a button for that, it is would recommended to use a delay after the gate as well to make sure that no other things will change when you send the reset through the system. Also remember that you want the lights to be OFF, default and then turn on when you want to reset.

The Translator[]

This works almost the same as any normal decoder system that uses redstone repeaters. As mentioned before, the repeaters have the ability to pass power into a block, this is what you will exploit in your translator.

To get all the different signals to the translator you will need to choose a position, it is suggested to position it somewhere to the side of your decoder, but you need to remember which light means which. To keep the lines from interfering with each other, it is best to put the lines of wire on alternate levels (create bridges). Remember to check your wires to make sure that the signal does not exceed 16 blocks. Now the first stage is to get all the signals together. To do this you use repeaters, which has the unique ability to prevent signal interference.

If you have done decoding before, you might have noticed that the signal is the wrong way round as you inverted it when you got it to the repeaters, so you might be thinking didn't you will need to invert them then before you got to the repeaters, well the answer is no unlike most signals Morse code has lots of lapping over like A and E, E is dot and A is dot dash, as you can see the E is contained within the A for this reason, you will need to be able to define the requirements more, to do this you will in the end have basically have two and gates for each letter, but it will explained more of later.

To start, you will want to create a line of repeaters all the way along, remember if you haven’t sent a signal through your system, or you've reset it which it will be mentioned at the end, then all your repeaters right now should be on, if there not then you need to go back and check, first of all check that you've reset them and then check your wiring to the translator. If you have got them all on, then it should be good, so far. After your line of repeaters you're going to want to create a line of any block, it is suggested to use sandstone or mossy cobble for mine but it's personal, it won't affect the wiring. Now continue this on so that you have 26 lines of blocks, the number of letters in the English alphabet. So, now you can kind of see your translator taking shape now to make the process easier for yourself later, it is suggested to place redstone torches all the way along the blocks on every row, you'll understand later. That took some time didn't it; be warned that there’s going to be a couple of tasks like that in this tutorial. Once you've got all your redstone torches set-up you want to place a row of blocks above everyone pulse two extra blocks on the end that you want the final signal. By now, your rows should look something like this.

.

Now that you've got the repeaters and the lights set up, you want to place wire all along the top of your blocks to the end and then place a torch coming down the side facing where the input came from. As you can see, it has been moved this signal down, inverted it, and then put it to a light which will show the letter.

Above View of rows

This is the first and gate down. As well as being able to power the block and the wires next to that block, it also powers the wire under nether, you can use this feature to be able to create the next and gate; sort of, but before then, you are going to go through and program the first and gate, now as you have already placed all the torches it is now quite easy to program in, basically you want to pull up your Morse code showing you the different signals and then remove the torch that is it meant to be, remember that it will go in pairs, dash dot, dash dot, dash dot and so on, so to program in A which is dot dash you need to remove the 2nd and the 3rd torch. It is very important to make sure you get the right end display. Although, it can always be done at the end, or with the next step, which is to create the second and gate, this will in the end mean that the signal will only be on when all the criteria is full filled, to stop any of the incorrect lights showing. Now, to do this you are going to want to remember where the gaps are in the torches, for example, by giving the gaps all numbers and writing down which ones are empty. It is suggested to do this row by row. Create a trench directly underneath the torches two deep, and now for everything gap that you had place a block and a redstone wire on to it and feed the redstone wire overall of them to the opposite end of the torches away from where your display is. This is what 'A' would look like underneath, now you want to get this message up to the top layer of your row, where the redstone wire is. You do this using vertical wiring and then feeding a wire to connect them both up, like this. Once this is all connected up to each one, you're complete you should now go test your system for any mistakes.
