Turning the Raspberry Pi Into an FM Transmitter – Imperial College Robotics Society Wiki January 16, 2013

Below is some code that was hacked together over a few hours at the Code Club pihack. It uses the hardware on the raspberry pi that is actually meant to generate spread-spectrum clock signals on the GPIO pins to output FM Radio energy. This means that all you need to do to turn the Raspberry-Pi into a ridiculously powerful FM Transmitter is to plug in a wire as the antenna as little as 20cm will do into GPIO pin 4 and run the code posted below. It transmits on 100.0 MHz.

PiBorg – Control Robots from your Raspberry Pi

Welcome to PiBorg.org, a robotics control add on for Raspberry Pi.

If you don’t know about Raspberry Pi, you can find out about it here.

The PiBorg is an open source add on board capable of controlling two DC motors from your Raspberry Pi model B, with feedback from a potentiometer or incremental encoder, or without any feedback.

Simulating the circuit in software is in some-ways harder to do than to actually built the circuit in electronic components, but in can be used as an introduction to building up simple RC networks in a teaching environment.

To build the game, you’ll need almost all the bits in the SK Pang starter kit – 12 x LEDs, 12 x 270Ω resistors and one button. You can build it with less LEDs if you don’t have enough.

Top 10 Raspberry Pi Myths and Truths – Scott Hanselman December 18, 2012

First, let me go on the record as saying I’m a huge Raspberry Pi fan. If you haven’t heard already, a Raspberry Pi is a small but complete $35 computer (or $25 without Ethernet). It’s a complete 700 MHz ARM CPU with a GPU and 256MB of RAM. It has two USB ports, Ethernet, Audio as well as video out over RCA (Composite) or HDMI at 1080p. It uses an SD Card for its hard drive and takes 5V at >700mA of power over a mini USB. You can order one from Farnell online and there is a waiting period.

The future has been so disappointing. We were promised force fields; teleporters; and androgynous, android manservants. Instead we got cagoules, budget airlines and robovacs. And what do you do with a robovac when it reaches the end of its useful life? You stick a Raspberry Pi on it and make it into a proper robot of course

The goal of this tutorial is to run a cut down, bare bones operating system and to create an image thats sole purpose is to run MAME arcade ROMs. The tutorial is written with a Windows user in mind but would also be useful for new Raspberry Pi owners who are not familiar or comfortable with the Linux shell.

Intro

Raspberry Pi Owncloud (dropbox clone)

What I’m going to show you is how to build a your own personal dropbox like service using a raspberry pi and some software called OwnCloud. ownCloud gives you freedom and control over your own data. It’s a personal cloud which runs on your own server.

If you don’t want to go through the steps for downloading and setup up the software you can download the image I have setup from here. While I have done everything I can to check this is working it should be understood that you use at your own risk. If you do download the image you can skip to step 5.

Hi,

for playing, e.g., Zork I have found the post at http://kimondo.co.uk/play-zork-on-the-raspberry-pi/.

The installation is done (as root) with these lines:

CODE: SELECT ALL

apt-get install -y frotz

wget -U firefox http://www.infocom-if.org/downloads/zork1.zip

wget -U firefox http://www.infocom-if.org/downloads/zork2.zip

wget -U firefox http://www.infocom-if.org/downloads/zork3.zip

unzip zork1.zip -n -d /home/pi/RetroPie/roms/zmachine/zork1/

unzip zork2.zip -n -d /home/pi/RetroPie/roms/zmachine/zork2/

unzip zork3.zip -n -d /home/pi/RetroPie/roms/zmachine/zork3/

rm zork1.zip

rm zork2.zip

rm zork3.zip

These are actually the installation steps made by the >>RetroPie Setup script<<, which also allows the installation of Frotz with the most recent update .

Start Programming C with raspberry Pi December 18, 2012

Posted by sandyclaus in RPi Tutorial and Programming.

This set of instructions won’t suit everybody but I’ll try to be as generic as possible. I installed the Debian Squeeze distribution, so the programming tutorials are based on that. Initially, I’m starting off by compiling programs on the Raspi but given its relative slowness to any PC in the last ten years, it’s probably best to switch to developing on another PC and copying the executables over.
