I know there was a thread a while back about the Raspberry Pi, a $35 computer the size of a wallet, but since that thread's been dead for a while I decided it might be better to just make a new thread entirely.
Anyone else have one of these things? They're a lot of fun. Share your stories!
As for myself, I've managed to get a full Minecraft server running on a 512 version B. It sits in a lego case of my own design, next to a small switch for internet.
I'm powering it through a monitor that also serves as the usb hub for the Pi, but the monitor isn't actually the Pi's display.
Instead, I'm using it as a secondary display for my laptop, and I've maximized an SSH client (puTTY) on that monitor; that way, I can share a single keyboard and external monitor between my laptop and the Pi. If I want to watch the Pi's boot log, all I have to do is set the monitor to its digital input (the Pi's HDMI, converted by cable to DVI). The VGA input is connected to my laptop, so once the Pi is up and running I can toggle back to having two monitors on my laptop without moving a cable.
As for the server itself, it runs fairly smoothly, though I've had to fiddle with the properties.
First off, it isn't the Pi version of the game, it's the full computer Minecraft we all know and love. I'd put BTW on there if I wasn't using Bukkit!
The server's on 1.4.7 right now, I haven't tried 1.5.x yet.
I overclocked my Pi a bit (the "high" setting in raspi-config) and disabled animals, mobs, and the Nether.
The server throws a lot of "[warning] can't keep up! " messages, but that seems to be related to the Pi's lack of a real-time clock, because when I was testing it alone, it was nearly as smooth as singleplayer: no lag on movement, blocks place and break properly, there are slight chunk-render delays on occasion, and items sometimes take a second or two to get picked up.
All the data for the server is on an external usb stick instead of the SD card. I don't know if it makes a difference for read speed or anything, but it works well enough as-is.
Hey, for 512 Mb of RAM, that isn't bad. I'm going to get some friends on later to see how well the server takes to multiple players at once, but I'm pretty confident it will work.
Picture time~! (warning, large images)
Nothing too fancy yet, it's only been a minecraft day or two.
The setup itself.
Sorry it's so dark. I realized afterward that I could have set the time to day through the server...
