Is there a more efficient way to wire a row of pistons?

Question

I want to create two sets of two adjacent pistons with a two block gap between them for a melon farm. It seems as though I'm using a prodigious amount of redstone for each section. This is my first redstone circuit, but is there a better way?

Answer

Yes, there a quite a few ways.

Come with me on an adventure in redstone optimization!

You can place Redstone Repeaters behind each of the pistons as shown below. This will direct the input into the piston and prevent those annoying loops that usually don't accomplish anything. This will take up much less space, but uses a total of 18 redstone dust.

A more redstone efficient design would be this. It uses only 11 redstone dust. Other players not required. This method works because a piston can be powered by an adjacent powered block.

---

This design (courtesy of Tristan) uses a minimalistic 7 redstone. The lever powers both the block that it occupies and the block it attaches to. The hole on the right is required to keep the signals going to the two pistons separate.

---

Finally, this uses a measly 4 redstone. Since you're powering 4 pistons, I think 4 redstone is likely as low as you're going to get.

Science!
