R-Pi as Arduino HDMI server

jokkebk over at Code and Life has developed a simple “HDMI server” for the Raspberry Pi that uses pyserial to receive commands over Pi’s serial interface, and pygame to display graphics primitives according to those commands. An Arduino client was written to send these commands to the Pi, drawing a string of blue rectangles to […]

Twelve Pi’s of Christmas R-Pi charity auction

The Raspberry Pi crew is in the midst of a charity auction event dubbed the Twelve Pi’s of Christmas. The R-Pi crew explains: Last year, we auctioned the very first Raspberry Pi Model Bs to come off the line to raise money for the Raspberry Pi Foundation. We’re doing the same this year, but instead […]

Raspberry-Pi solar-powered FTP server

David Hayward over at CNET UK has posted an article describing how he designed a solar powered FTP server based on the R-Pi. The additional hardware consists of a solar cell array and 4 NiMH batteries. The solar panel is by Cottonpickers, but you could use any appropriately rated panel. (Be sure to include appropriate […]

R-Pi ARM-side source for BCM2835 SoC graphics driver released

The Raspberry Pi crew reports that the VideoCore driver code which runs on the ARM is now available under a FOSS license (3-Clause BSD to be precise. “The BCM2835 used in the Raspberry Pi is the first ARM-based multimedia SoC with fully-functional, vendor-provided (as opposed to partial, reverse engineered) fully open-source drivers, and that Broadcom […]

Raspberry Pi model B gets double the RAM

R-Pi’s 256MB just doesn’t cut it for your Java application? The Raspberry Pi foundation let us know that all outstanding Model B orders will be getting double the memory. With this in mind, we’re pleased to announce that from today all Model B Raspberry Pis will ship with 512MB of RAM as standard. If you […]

Control Raspberry Pi’s GPIO pins via a web page

This Instructable might just complete your plan to take over the world with the Raspberry Pi. Control R-Pi’s GPIO pins via a web page. Install some soft, type in a few commands, and you’re set. The base package includes: – A server program that runs on the Raspberry Pi to read variables – A MySQL […]

BrewPi open source brewing controller

Here’s an interesting project to automate your home beermaking process. “BrewPi is an open source fermentation controller that runs on an Arduino (for now) and a Raspberry Pi. It can control your beer temperature with 0.1 degree precision, log temperature data in nice graphs and is fully configurable from a web interface.” The Arduino is […]
