Dear: Element 14 Community   I am letting you guys know I am building a raspberry pi cluster based off of a laser cut frame I designed and cut on a laser cutter and designed with librecad.   Let me just explain first of all my experiences as an engineer. Here are a list of accomplishments I have made within the past few years.   Built a video game for xbox 360 from XNA C#. Built a 3D printer. Built several robots with Arduino. 3D printed a  ton of junk in my basement. ...
This's a pretty clever design, and I thought to myself "it wouldn't take much to make these into actual cartridges, if the Pi Compute was used as an edge connector".   Still, the images speak for themselves, and the creator used Berryboot to allow the OSs to be changed easily.   Raspberry SUPER PI Super Pi: Switch OS by switching cartridges Super Pi: Looks almost like a SNES Super Pi: Especially when next to a controller   Source: Imgur Gallery / blog     ...

This is just a High Level Diagram approximation of what the Pi 3 consists of. It is based on various bits of information on the Internet, and could be incorrect in places. If you have any corrections, or additional bits of information/suggested tweaks, please let me know and I'll get the diagram updated. Thanks!   Diagram revision: 4 ...
So, I don't know if you've seen, but there's a brand new Raspberry Pi Compute module launching today!   As you guys know, having been around the Raspberry Pi block quite a few times, the Compute module isn't really aimed at the makers among us -- this is more for a commercial, or industrial market, where the brains of a Pi need to be embedded inside a prototype, platform, or some other manner of professionally-built project.   But we'd still be interested in hearing your thoughts on ...
(LEFT) Boot Screen of Rasbian for PC operating sytems. (RIGHT) This is Raspbian running on a PC. (via Raspberrypi.org)   The Raspberry Pi Foundation has created a version of the Raspbian OS for MAC and x86(Windows) personal computers. Raspbian is the Debian based Linux distro that until now, was intended specifically for the Raspberry Pi series of SBCs. This OS is purported to need a minimum of 512MB of RAM but you can see in the comments that at least one user got it running on a machine w ...
I decided to write this post due a silly trap that to be honest I think should be avoided in next updated of the raspbian pixel version. The last official downloadable version at the date is the 2016-11-25-raspbian-jessie.img   Here and there there are tons of posts of users that are not able to connect via SSH to a fresh raspbain installation on a PI3 of this version; I had the same problem too and tried to solve the problem thinking to the most common issues like removing the .ssh/known_ ...
