A redstone repeater just delays the redstone signal.
In order to get a repeating signal, you need a (rapid) pulser.
Search on the minecraft wiki to find how to make one.
Make a loop of the desired number of redstone repeaters and redstone so that the current will only travel in one direction, then set all the repeaters to the same value. After that, add a very quick redstone signal at one point and it will pulse. Note that you must have at least 2 repeaters.
This is a bit of a complex question, so I'm gonna post a link to the Minecraft wiki page for redstone repeaters. Here you go:minecraftwiki.net/wiki/Repeater
You could build a cool building, it is also a crafting material for buttons, stone pressure plates, stone slabs, stone bricks, and redstone repeaters.
It does three things. - It can extend a redstone charge. Normally a charge only carries for about 16 blocks. A Redstone repeater will extend it by another 16. - Delays a signal. The lever setting can add a delay between the time when the repeater receives charge, and when it passes it on. A long chain of repeaters can add delays of seconds or more. - Directs a signal. Imagine you want three adjacent, but seperate lines of redstone charge. If you use redstone dust, the lines will link together, as the dust forms little + shapes. However if you use a line of repeaters, the current can be transferred in adjacent channels without bleeding into each other.

So you can repeat stuff.
There are good examples on ZirumsHeroTWR (YouTube) and kiershar (also on YouTube). Search up Minecraft Cannon on the Forums.

Signal repeaters are generally used in the telecommunication and electronics industries. There can be passive radio signal repeaters, multi-port repeaters, optical signal repeaters for optical fiber and digipeaters which repeat packet data.

If you want to make one out of redstone and pistons, It will need to be stackable vertically and horizontally so adding in more will not be a problem and will make things much more simple. The smallest pixel (small dot that is controlled independantly) size that can be made to stack is 2x2. 1.) Start by making horizontal rows of blocks stacked on top of each other with a one block gap above each row. Note: the rows need to be an even number of blocks long. 2.) on the long side of each row, put a line of sticky pistons facing out 3.) put sticky pistons facing the same way on top of every sticky piston you just placed. Note, it should look like a wall of sticky pistons. 4.) put your choice of block for the front of the screen on the sticky side of each of the sticky pistons. 5.) now, on the opposite side of the pistons, on the horizontal rows, place redstone repeaters facing the pistons on top of each of the blocks in your horizontal rows. 6.) add a second layer of horizontal rows directly behind the first layer 7.) from left to right, on top of the blocks you just placed, put alternating redstone and repeaters (redstone, than repeater, than redstone, etc...) 8.) add another layer of horizontal rows like in step six 9.) repeat step seven, except put two redstone, than two repeaters 10.) add another row of repeater, nothing, redstone, redstone 11.) add a final layer of redstone, nothing, redstone, nothing Each of the redstone from step 11 will power an individual pixel in the screen. If you were looking for a color screen, there isn't a way to do that yet, although I have seen one version where they used redstone to open certain doors and letting you see colored wool inside.
You have to mine redstone ore.
You get redstone dust and place it on the ground or a block. You can't put redstone wire on walls or roofs.
As glowstone gives off light, the only monster than can spawn on it is a slime at the bottom of the map.
Redstone Blocks now exist in Minecraft 1.5. You can make them by combining nine redstone dust on the crafting table.
