What is a Transmutation Tablet?
The Transmutation Tablet is the workbench of ProjectE. (Project E is one of the main mods included in Tekkit Legends.) It allows you to transmute blocks and items, allowing you to trade many low-value items for a few rarer ones, for example. You can only create items that your Tablet has already "seen", but once it has "learned" an item it is remembered forever and you can create it at will, even if you no longer possess any of that item. At first, the interface may be confusing, but it is not hard to learn and become familiar with.
The Transmutation Tablet gives you much more control over the transmutation process compared to the Energy Condenser, and does not require you to already possess the item you desire, provided you have previously taught your Tablet that item. However, the Energy Condenser is much more suitable for transmuting massive quantities of items (e.g. unwanted mining waste) into a single type of item. However, you can craft an Alchemical Tome and place it in the burn slot of the Transmutation Tablet, which unlocks every item in the Transmutation Tablet, but it is the most EMC expensive item in Tekkit as it requires 2 fully charged Klein Star Omegas. The Transmutation Tablet also has an EMC value. It is useful if you are on a server so that you could use the Energy Condenser and make a ton of them.
Usage
The circle on the left of the Tablet's GUI is called the Input Matrix. When an item is placed on this circle, the EMC value of that item is displayed, and previously-learned items of equivalent value or less will appear in the Output Matrix on the right. You may then remove items from the Output Matrix, consuming EMC in the process. Leftover EMC is stored for later use.
Multiple items can be placed in the Input Matrix in order to use their combined EMC. If you place a stack of items in the Input Matrix, then only the EMC of one item from the stack will be shown, but the tablet will take extra items from the stack one by one as more EMC is required.
You may place an item in the centre of the Output Matrix in order to target that item. This will cause the Output Matrix to display only items that have an EMC value equal or less than the target, with the targeted item itself showing up at the top. Use this if your Tablet is not showing the item that you desire.
The slot at the bottom, marked with a flame icon, allows you to dispose of unwanted items in exchange for EMC, which will be stored for use in transmutation.
EMC left behind is stored in a Transmutation Tablet when you close it, and will be there the next time you open it. Items, however, will be ejected if not removed before closing the Tablet. All of your Tablets share the same EMC storage, so your EMC will be there even if you use a different Tablet. In multiplayer, using someone else's Tablet will still bring up your Tablet interface, not theirs.
If you put a Klein Star into the left side and then burn "MATTER" items, the Klein Star will get charged with EMC.
Bugs
Don't put Solar Panels, Sapphire Blocks, Nikolite or Obsidian Pipes into the Tablet, as they will disappear, without giving anything in return. In short, be careful putting anything into the Tablet not listed below, you've been warned. Some items that are unrecognized by the Tablet will be harmlessly put on the floor and you'll suck them back up into your inventory. However, if the item is to disappear, it can usually be found by digging under the Tablet for a while.
If you store too much EMC in the Transmutation Tablet (over 2 billion) it will overflow and become negative (you will then have to keep feeding it Matter or Fuel, whichever it's locked to). Be careful when inputting stacks of items with a high EMC. This bug is due to the way computers store integer values in binary format- in this case a 32-bit signed integer is being used to store the EMC value. A 32-bit integer has approximately 4.29 billion unique values- ~2.15 billion positive numbers and ~2.15 billion negative numbers. When a 32-bit signed integer reaches 2,147,483,647 and increases by one more number it will overflow and tick over to -2,147,483,648. This bug could potentially be fixed by either imposing a hard limit of 2,147,483,647 into the Tablet, storing the value in an unsigned integer and imposing a hard limit of 4,294,967,295 or converting the value into a floating-point value.
Occasionally, if you get the items quickly when reaching low EMC you will go negative EMC.
There is a vanishing EMC glitch that occurs when any EMC (any amount) is stored within the Transmutation Tablet (as in not being completely used to equal zero). A simple fix would be breaking the Transmutation Tablet and replacing (This will not effect the EMC or Alchemical Tome upgrade). Another solution would be burning any item with EMC, but this can cause some items not to appear on the left side.
Hopefully you had enough information! questions can always be asked.
