Turning the Raspberry Pi Into an FM Transmitter - Imperial College Robotics Society Wiki Steps to play sound: (Created by Oliver Mattos and Oskar Weigl. Code is GPL) sudo python >>> import PiFm >>> PiFm.play_sound("sound.wav") Now connect a 70cm (optimally, ~20cm will do) or so plain wire to GPIO 4 (which is pin 7 on header P1) to act as an antenna, and tune an FM radio to 103.3Mhz. Download the module here: [Download Now!] (this contains both source and a ready to go binary. New! sudo . How to change the broadcast frequency Run the . The second command line argument is the frequency to transmit on, as a number in Mhz. sudo . It will work from about 1Mhz up to 250Mhz, although the useful FM band is 88 Mhz to 108 Mhz in most countries. Most radio receivers want a signal to be an odd multiple of 0.1 MHz to work properly. The details of how it works Below is some code that was hacked together over a few hours at the Code Club pihack. If you're v. smart, you might be able to get stereo going! Accessing Hardware

Quick start guide What you will need Required SD CardWe recommend an 8GB class 4 SD card – ideally preinstalled with NOOBS. You can buy a card with NOOBS pre-installed, or you can download it for free from our downloads page.Display and connectivity cablesAny HDMI/DVI monitor or TV should work as a display for the Pi . For best results, use one with HDMI input, but other connections are available for older devices. Not essential but helpful to have Internet connectionTo update or download software, we recommend that you connect your Raspberry Pi to the internet either via and ethernet cable or a wifi adapter.HeadphonesHeadphones or earphones with a 3.5mm jack will work with your Raspberry Pi. Plugging in your Raspberry Pi Before you plug anything into your Raspberry Pi, make sure that you have all the equipment listed above to hand. Logging into your Raspberry Pi Once your Raspberry Pi has completed the boot process, a login prompt will appear. Read more in our documentation.

Configurer la Raspberry sans écran François, Si vous avez accès à votre routeur, vous pouvez utiliser votre routeur pour trouver l'adresse IP de votre RPi, qui devrait être acquis via DHCP. Vous pouvez ensuite SSH à l'aide d'un programme appelé PuTTY. Cela vous permet d'obtenir une fenêtre de console et vous pouvez commencer à configurer le serveur VNC pour exécuter au démarrage. Ensuite, vous pouvez utiliser VNC pour accéder à l'interface graphique de votre RPi. Je n'ai pas mon RPi relié à un moniteur, et l'utiliser exclusivley via SSH et VNC. Quant à la carte mémoire, ne vous inquiétez pas à propos de ce que vous voyez dans Windows. Amusez-vous! PS: j'ai utilisé Google Translate pour prendre votre message du français à l'anglais, puis d'écrire cette réponse. There are 10 types of people in this world.

Raspberry Pi The Raspberry Pi is a series of credit card-sized single-board computers developed in the UK by the Raspberry Pi Foundation with the intention of promoting the teaching of basic computer science in schools.[3][4][5] The original Raspberry Pi and Raspberry Pi 2 are manufactured in several board configurations through licensed manufacturing agreements with Newark element14 (Premier Farnell), RS Components and Egoman. These companies sell the Raspberry Pi online.[6] Egoman produces a version for distribution solely in China and Taiwan, which can be distinguished from other Pis by their red colouring and lack of FCC/CE marks. The hardware is the same across all manufacturers. In 2014, the Raspberry Pi Foundation launched the Compute Module, which packages a BCM2835 with 512 MB RAM and an eMMC flash chip into a module for use as a part of embedded systems.[10] Hardware[edit] Processor[edit] Performance of first generation models[edit] Overclocking[edit] RAM[edit] Networking[edit] Peripherals[edit]

Raspberry Pi: Up and Running For those of you who haven’t yet played around with Raspberry Pi, this one’s for you. In this how-to video, I walk you through how to get a Raspberry Pi up and running. It’s the first in a series of Raspberry Pi videos that I’m making to accompany Getting Started with Raspberry Pi, a book I wrote with Shawn Wallace. If you’re intrigued by what you see but don’t yet have a Raspberry Pi, check out the Raspberry Pi Starter Kit in the Maker Shed. Keep an eye out for more Raspberry Pi videos in the coming months and leave a comment if there’s any particular material that you’d like to see covered in a MAKE video. Subscribe to How-Tos with Matt Richardson in iTunes, download the m4v video directly, or watch it on YouTube.

With Raspberry Pi and Cotton Candy, Linux Launches a Revolution All the world may be agog over Microsoft's Windows 8 previews this week, but at the same time a quiet revolution is taking place. It's powered by Linux, it costs a fraction of Windows' price, and its first tangible evidence is now available in not just one but two “sweet” forms: Raspberry Pi and Cotton Candy. Like the idea of freedom from the upgrade treadmill and a price that won't put you behind on your rent? The Raspberry Pi There's been talk about the ARM-based, education-focused $25 Raspberry Pi for quite some time already, but this week the diminutive device made its official debut. That's been nothing if not exciting to watch, particularly because the launch was so successful that it brought the UK-based project's site to its knees amid overwhelming demand. Premier Farnell and RS Components have both signed up as licensed manufacturers of the devices, the first run of which apparently sold out within an hour or so. Raspberry Pi devices include a remix of Fedora Linux. Cotton Candy

Raspberry Jam at Milton Keynes – National Museum of Computing – Gertboard Demo Rig Yesterday I went to my first Raspberry Jam – a get-together of Raspberry Pi enthusiasts. This one was in Milton Keynes at the National Museum of Computing. It happened to be run by Peter Onion, who I already knew from the world of aeromodelling. So it was a no-brainer for me to go to… meet an old friend (he’s not that old)visit a museum of computersget to talk to people about the Raspberry Pi and Gertboard and demonstrate themsee what other people are doing with the Pi (nobody else had a Gertboard – ner ner nee ner ner :p ) It was great. It wasn’t all plain-sailing though. Toasted servo for lunch. Fortunately – well, there’s no fortune about it really, since I always carry spares – I had a spare servo. I did manage to tear myself away from my stand (thanks to my security arrangements :rotfl: ) Rev 1 Pi has no screw mount holes, so I made my own arrangements. A closer look, you can see the hot glue. On the rev 1 Pi board there are no screw-holes, so I had to make my own arrangements ;).

RPi Easy SD Card Setup Back to the Hub Getting Started: Buying Guide - for advice on buying the Raspberry Pi. SD Card Setup - for information on how to prepare the SD Card used to boot your Raspberry Pi. Basic Setup - for help with buying / selecting other hardware and setting it up. Beginners Guide - you are up and running, now what can you do? Advanced Setup - for more extensive information on setting up. Trouble Shooting - some things to check if things don't work as expected. The Raspberry Pi will not start without a properly formatted SD Card, containing the bootloader and a suitable operating system. You will also need to choose a distribution. Some Raspberry Pi kits will come with a ready-to-go card with the distribution pre-installed, or these can be bought separately. If you don't have a pre-installed card you will need to prepare your own. Buying a preloaded SD card from a reputable supplier means that you can just plug it in and power up your Raspberry Pi; it should then just work. Using NOOBS Using Etcher

Mobile Raspberry Pi Computer: Build your own portable Pi-to-Go Aw, yes, the Raspberry Pi Computer, a credit card size mini PC that only cost $35. There are so many possibilities and uses for these small nano PCs. People have made them into PVRs (personal video recorders), retro gaming machines, weather stations, in-car PCs, jukeboxes, and so many more creative ideas. When I started this project four weeks ago, I just wanted to see if it was possible to make an ultra portable, mobile Raspberry Pi that you can take to-go. My mobile Raspberry Pi Computer is now complete and because this is an open source project I wanted to show you everything, including how to build one yourself. Just a quick blurb about myself. LCD Screen The LCD I used is from an after market backup camera system that can be installed in a car. Battery Pack First off, be very careful when messing with lithium-ion batteries. Charging the battery was easy, I just purchased an after market laptop battery charger. Internal Powered Hub Extended Storage 64GB SSD, yes I did! Operating System

Spark Linux Tablet Up for Pre-Order, Dev Discusses Economics of Project The upstart Spark Linux tablet is up for pre-order at for a target price tag of 200 euros (about $263 USD). You can indicate how many tablets you’re interested in, and your priority number will ensure you’re among the first to receive yours. The Spark folks are hoping to get a strong sense of device demand before the tablet launches. Developer Aaron Seigo also posted a new blog today discussing the financial aspect of the project. Overall, the idea is to put money that comes in back into the project and to Free Software (especially those around open devices) in general. “Where these funds will be targeted will depend on what needs doing, what needs supporting the most and how successful the products are in the market,” said Siego in the post. Seigo notes that part of that will be investing in partnerships with other people and companies that can create software and technologies that enhance Spark.
