Best way to keep nasty creepers out of my base

[MoJoCyAnIdE]

If you have any new and exciting idea's of how to keep creepers and more mobs out of my base. Please note I am not extremely rich, and do not have bulk recourses. My base has a waterfall entry, which means you walk through a waterfall to get into my base. Any ideas would be appreciated. Thanks!

If you put torches (or power tool Lux capacitors) in diagonal 7*7 grid (or two 13*13) mobs won't spawn.

a bukkit plugin called residence is what I used to use, then had ICBM mod installed and I let the laser turrets take care of it, now I just live in my glacticraft spacestation and they don't spawn there

Skipping past MFFS to talk about other things first, Kotja's suggestion is still is the most basic method. I bet you could automate filling a vanilla dispenser with arrows with some AE magic. Some of the OpenCCSensors can be combined with ComputerCraft scripts to react on a couple of events like proximity or time of day. It's just a new trigger for old trap types.

Now I'll return to MFFS. The Modular Force Field System has a block called the Interdiction Matrix which can do things like stop mobs and friendly mobs from spawning, kill mobs and/or friendly mobs, attack players and a few other things. It's an end game thing though as it takes a sizable amount of power. The Tekkit wiki is rather bare on MFFS but search Youtube. The mod overviews explain how to use the mod but it's fairly straight forward.

mffs is fun too, I use it to replenish my leaves in my space station for air generation

Get some cats.

Then get a MFR safari-net and launcher, and fire cats at the creepers.

You could try to lux capacitor them to death... pew pew pew...

[TonyVS]

fire cats at creeper lol, that reminded me of

[Lethosos]

Or fire pigs. There's a mod, Trailmix, that does that.
