So, Minecraft.

That being said, does anyone have any advice for an automatic tree harvester? I've been trying to figure out a way to use pistons to push the logs outs and down to the ground, but I'm not having much success.

You can't harvest wood blocks automatically, but you can use pistons to move them around. You'll still have to manually punch them to harvest the wood, no matter how you do it.

My son and I made a huge addition to our home. We had a little hostile mob spawner which worked fairly well, but it just wasn't big enough to provide us with as many arrows/gun powder/bones/etc that we wanted in bulk. So we set out to make it bigger. We originally had a spawner with two 3x50 spawning pads which just wasn't producing enough, so we decided to quadruple it to eight pads. We also tweaked the water delivery system a bit to make it more efficient. My son decided that a cobblestone exterior was ugly so he chopped it all down and put in stone brick blocks.



Here's my son working on the roof. The spawn room is about 20x50 and has eight spawn pads (4 on each level, and easily expandable in the future). The cobblestone slabs are to prevent spiders from spawning and gumming up the works.



Here's the interior after the roof was put in. We'll knock out the torches shortly to make it active.



From the outside it's a pretty ugly stone brick shell.



I found this sheep that had somehow wandered near our home. I have no idea how it got here, because our home is nowhere near a place that passive mobs can spawn. It walked a long way.
