Okay people. There are 1.5 Servers out. (Theres still no 1.5 plugin)

This is about what to use about redstoning. Firstly, We have the Solar Panels. It is used to generate redstone light. It gets energy at the morning and it saves energy at night. It's like a generator.

Redstone Block is next. It can activate all kinds of redstone contraptions. You can craft it by a 2 x 2 grid.

Also, We now have the TNT Minecart. It's like a suicide bomber but its a Minecart. To allow the TNT to ignite. you need to have an Activator Rail.

These Redstone Contraptions can help our lives in Minecraft and redstoning way more easier in many ways.

The Dropper for example doesnt shoot out arrows. It just drops the arrows.
For the Hopper this time. It is like a collector. When you put the Hopper on top of a chest. It will work like:
You open your chest but you dont want to transfer stuff and all those. You just drop the item in the Hopper and it will somehow be transferred to the chest. With or Without chest. You can attain your items back by destroying the hopper. It's like an extra storage place for your items.
