Energy-O-Mat

Trading between players

Three blocks to sell things while you are away. All three belong to the player who places them (the owner): nobody can break them (the safe, not even with explosions), and only the owner removes them, with the wrench (shift + click).

Personal safe

Personal Safe: a 54-slot chest that only its owner and operators can open. Hoppers and pipes cannot touch it. It can be removed when empty. It is the best place to keep the goods and payments of the other two.

Trade-O-Mat (selling items)

1. Attach an inventory with the goods: a chest or, better, a personal safe of the same owner.
2. The owner sets in "Wants" what it charges (for example Iridium Coins) and in "Gives" what it sells, with the amounts.
3. Anyone puts the payment in the input and gets the goods in the output. The payment is stored in the same inventory.

Energy-O-Mat (selling energy)

It is a toll cable:

1. The owner's energy comes in through any side except the front; it goes out through the front only while the customer has credit.
2. The owner sets in "Wants" what it charges and, with the buttons, how many EU each payment gives (4,000 at first).
3. The customer puts the payment below; it goes to a chest or safe of the owner attached to it.

• With no price, or nowhere to store the payment, energy passes for free.
• It outputs LV packets (32 EU), up to 512 EU per tick.
• It uses no energy: it holds up to 10,000 EU of the owner's while it waits for customers.
• While energy passes it gives a redstone signal.
