Calculator

The item material calculator is now up and running. Put in the amount of any item you need to make and it will tell you the amount of materials needed to make it. It will also show you the materials broken down into their raw forms (e.x. Wood Planks ---> Wood).

Mobile Site

I've finally completed the mobile version of the website! It should automatically direct you to the new version if you access the website from your phone/tablet. An Android/iOS app is in the making, and it should look pretty similar to the mobile site. Leave a comment here or email me at admin@minecraft-craftingguide.com with your opinions about the site.

How to Make an Infinite TNT Dropper

There were a lot of bugs in the 1.7 update with item replication, and most of those have been fixed in 1.7.2. However, there is one bug still working (at the moment) that allows for easy mine shaft creation. This will undoubtedly be fixed in the near future, so take advantage of it now.

First, build a large tower out of dirt. You need to be high enough off of the ground so that the explosions don't cause TNT blocks to ricochet back up to you, like what happened in my first try with this. Build a small 2 block wide platform that is six blocks long. On the left side, remove the last 2 blocks.

Place a sticky piston in the hole facing outwards.

Attach a TNT block to the piston.

Place 2 lines of redstone one block apart from each other.

Place a redstone repeater facing towards the piston on the left side.

Place another repeater in the opposite direction.

Place a redstone torch next to one of the redstone wires to provide power to the circuit. Remove the torch after placing it and the power will stay in the current.

This is the tricky part. Break one of the redstone wires and immediately replace it. This will make it so the current has a small portion of "off state" and "on state" which causes the piston to rapidly expand and contract.

Place a redstone torch on the end of the last dirt block. This will trigger the TNT when the piston is expanded, causing it to fall down and explode. TNT will also stick to the sticky piston and not explode, so each time it expands, a new live TNT block is created.

Sit back and watch the carnage.

When you've finished blowing stuff up, break any part of the redstone to stop it. Admire your handiwork from above.
