Raspberry ScoPi

Posted by fmanno Nov 30, 2012
Hi all, I received my Raspberry Pi a few weeks ago and I've been preparing for a project. One of the main issues when developing hardware is the dificulty to "see" the signals we're working with and debug our projects or prototypes. Osciloscopes are often either very expensive or very low-end. With the versatility of the Raspberry Pi to connect to almost ANY display (specially now with the Pi View) and its computing power I had the idea of building an additional board to turn the pi into a digi ...
  As I work with the Raspberry Pi, I find the slow navigation of the Linux OS to be a bit underwhelming. An alternative OS seems to add a bit of needed speed.     To Raspberry Pi users there are not many operating systems to choose from. The three formerly available to download from the website include Raspian “wheezy,” Soft-float “wheezy,” and Arch Linux ARM. All are some type of variants of Linux. As of recently, users now have an another operating syst ...

Sorry for any mistakes in English. I am Brazilian and I'm using Google Translator to support me   I working with geoprocessing and one of my recent works has been to study alternatives ways to process files of the European EUMETCast.   According to wikipedia, "EUMETCast is a scheme for Dissemination of various (Mainly satellite based) meteorological data operated by EUMETSAT, the European Organisation for the Exploitation of Meteorological Satellites. The main purpose is the Dissemi ...
Hello - I thought it might be helpful to highlight the process of updating a SD card to take advantage of the full 512MB on the new Raspberry Pi (Rev 2.0).  I am using an element14 pre-programmed SD card.  It contains Raspbian "Wheezy" with kernel and firmware from July 15th (per modification dates in /boot).  This is recent enough to boot the 512MB Rev 2.0 model, but only 256MB of the 512MB RAM will be recognized.   After booting the Pi, you can access the command prompt (c ...
Want to build this project? View Parts   Use your Raspberry Pi as an awesome media portal for listening to music, watching videos, and viewing pictures.   As an old-school XBOX modder, the first thing I wanted to do with my PI was turn it into a media portal. XBMC (Xbox Media Center) is an open source front end for Linux that used to only be available for the Xbox. These days, it is now available for PCs, Linux Distros, Boxee boxes, and most importantly Raspberry Pi.   I use ...
We are always evaluating project platforms that may fit within BlueStamp Engineering's goals.  Given the power, versatility, and growing user base, I am excited to check out the system as it may fit with what I think makes a great first project: Can a user get a response out of it within a few hours? Is there a solid community for ideas an support? Was I able to make a unique project without hating it too much? Are there lots of cool projects that can be completed?   To give i ...
