BeagleBone Black / Raspberry Pi / etc.
I bought a BeagleBone Black (only $45) a couple weeks ago and due to low supply and high demand I only recently recieved it. It's essentially a Raspberry Pi (single board computer), except it has like ~60 GPIO pins instead of like 8 (for attaching things like sensors and motors, etc). It also has a lot better specs than the Pi, which is only $10 cheaper.
My main goal in life is to build a robot that will chase my kittens around and shoot them with a water cannon. I plan on building a wheeled chassis that can flip upside down and still drive (in case it gets knocked down the stairs by an angry kitten). I plan to use infrared and ultrasonic sensors for navigation in addition to stereo video for image/pattern recognition. I don't really have a timeline as to how long this will take to get the software and hardware running decently, but I am guessing at least a month or two. I was going to attempt this with just a microcontroller, but it became apparent that as the more features I wanted to add to the robot, the more that multithreading would be necessary. Programming finite state machines in C is only viable to a certain point, then you kind of need the overhead of a complete operating system. I plan to install Arch Linux on it which is the most stripped down version I know of, then write a threaded GPIO framework in C++11. I also have plans to try and run EQ off of it, through Wine, but I need to obtain a MicroSD card and a MicroHDMI cable for it. I'm not sure what the graphics processing capabilities are, but I do think it should be able to at least boot up and run at a choppy framerate. Anyone else played around with these kind of boards before, done some cool stuff? | ||

I got an rpi, and use it as my media player for movies using xbmc. Streaming over wireless using a nas. I use raspbmc. I have used the raspbmc to stream video from an ipad using airplay that raspbmc supports. That worked good.
I had it running seq for eqlive to see if it would using an hdmi to dvi adapter. I plan to build a full size arcade playing old games like defender and put an rpi in it, using one of the game emulators. Havent decided whether to use the gpio or a keyboard convertor to usb card. H

Lack of netflix in rpi hasnt mattered to us. Have a roku 2 for that downstairs. That works good for old analog tube tv. I am a cheap skate. I need some new tvs. H

I really want to get a Parallella board as it is one of the few single board computers that comes with a multi-core processor. It also has a full-fledged FPGA integrated into it, so the possibilities of things you can do with it in terms of concurrent sensor readings are almost endless. I made an 8-bit processor with about 10 instructions on an FPGA a few years ago (CPU http://i.imgur.com/VRGsFi9.png / ALU http://i.imgur.com/FkcwVYA.png / Cache http://i.imgur.com/sqr09Ky.png) and have always wanted to make a 64-bit one with a full instruction set. The problem with the Parallella is it started as a kickstarter project and not all of the original donators havent gotten boards yet, so theres a long wait to get one.
They claim on their FAQ that it has 25x the computing power of the Pi. Quote:
