Notes If you've been following along here or on Twitter or Google+ you've no doubt seen the experimenting I've been doing with interfacing a Raspberry Pi in various ways with several retro computers like the Atari 800 and Commodore 64. My first project was using the Raspberry Pi to act as a converter for a USB gamepad to turn it into an Atari 2600 style joystick.Unfurl
NotesSince the Raspberry Pi was just sitting there, and the Amiga lacked (*) a network adapter - why not just connect the dots and get something up and running? I did, and it worked. Here's a quick writeup on what I did - if anyone's interested I can write a more detailed post with all the information I have.Unfurl
NotesREQUIRES PIBOW CASE – this is ONLY a replacement bottom layer. Laser cut from 3mm (1/8″) acrylic.
The belt is made from 1.5″ nylon webbing (better-equipped hardware, sewing or camping stores will stock this and related fittings), but it’s also perfectly suited to most camera straps if you have a DSLR + Raspberry Pi project in mind. The USB battery pack is an item from the Adafruit shop, held in place with cable ties.FeedUnfurl
NotesWe’ve been so busy we haven’t had time to do a proper write-up of this yet, but this year we decided to revamp the on-site displays (both overhead projections and LCDs).
And given that 2012 is pretty much the year of the Raspberry Pi, we decided to have a go at it using these amazing little boxes – after all, they’re pretty much perfect for the job given that they have an HDMI output, an Ethernet port and more than enough smarts to run a browser and playback H.264 video.Unfurl
NotesStealth Nighthawk F-117A is an easy to use XBMC device, with the same soc as the Raspberry PI, that makes it easy for you to run Open Source software that are supported by Raspberry PI, but with a nice, small and fancy design not bigger than your car keys.FeedUnfurl
NotesThe SPI (Serial Peripheral Interface) is a peripheral used to communicate between the AVR and other devices, like others AVRs, external EEPROMs, DACs, ADCs, etc. With this interface, you have one Master device which initiates and controls the communication, and one or more slaves who receive and transmit to the Master.Unfurl
NotesThis is a C library for Raspberry Pi (RPi). It provides access to GPIO and other IO functions on the Broadcom BCM 2835 chip, allowing access to the GPIO pins on the 26 pin IDE plug on the RPi board so you can control and interface with various external devices.Unfurl
NotesiP Solutions has created a Serial Peripheral Interface (SPI) command-line utility for the Raspberry Pi (www.raspberrypi.org) platform. The utility, spincl, is licensed under Open Source GNU GPLv3 and is being offered by iP Solutions as a free download with source included.FeedUnfurl
NotesHow cool would it be take a vintage 1940′s or 1950′s wooden radio and rebuild it as a modern Internet Radio? That’s the premise I had in mind when I started out on my first Raspberry Pi project.Unfurl
NotesIt has been quite some time since my last post about Firefox OS running on a Raspberry Pi, but the questions didn’t stop to come in “when will it be released”? Well, I’m sorry that it took so long (sometimes finding time is not that easy), but finally, here we are: the sources and build instructions are available!FeedUnfurl
Notes Whenever you come across a LCD that looks like it has 16 connectors it is most likely using a HD44780 controller. These devices provide the same pinouts making them relatively easy to work with. The LCD uses a parallel interface meaning that we will need many pins from our raspberry pi to control it. In this tutorial we will use 4 data pins (4-bit mode) and two control pins.FeedUnfurl
NotesHD44780 based character LCDs require at least 6 I/O lines from microcontroller to display data. Therefore, they are not suitable for low-pin microcontrollers like PIC12F series microchips. In this project, I am going to show how to drive an HD44780 based LCD display with only 3 pins of a microcontroller. I am going to demonstrate it with PIC12F683 microchip. The character data and command from the microcontroller is transferred serially to a shift register (74HC595), and the parallel output from the shift register is fed to LCD pins.FeedUnfurl
Notes Adding a LCD to any project immediately kicks it up a notch. This tutorial explains how to connect a inexpensive HDD44780 compatible LCD to the raspberry pi using 6 GPIOs. While there are other ways to connect using I2C or the UART this is the most direct method that get right down to the bare metal. FeedUnfurl
NotesWhen mine arrived, I didn’t really know what to use it for, but then it hit me: I can build an emulator box for all the NES and SNES games that I loved to play as a child.FeedUnfurl
NotesThe three models (all of which we use here at Digital Diner) are the Arduino, Raspberry Pi and BeagleBone. We chose these three because they are all readily available, affordable, about the same size (just larger than 2″ x 3″) and can all be used for creating wonderful digital gadgets. Before we get to the comparison, here is a brief introduction to each one.FeedEmbedUnfurl
NotesOk, so there’s no duct tape, toothpicks, or bubble gum involved, but I thought it’d be helpful to document a handy way to tinker with your Raspberry Pi, even when you’re almost completely lacking in the required external paraphernalia.Unfurl
NotesFor running systems with a Raspberry Pi computer which do not require any auxiliary devices to be connected. For example web, FTP, file, media, database servers. Yet the Raspberry Pi device is still accessible enough in isolation, to be able to administer the system independently.Unfurl
NotesWebIOPi is a REST framework and a webapp which allows you to control your Raspberry Pi's GPIO. Just install it on your Pi, and use any browser from your network. It's useful to start enjoying GPIOs and also to debug some circuits without writing any line of code. It also allows to control your Pi's GPIOs over Internet, so it's a good starting point for home remote control. Unfurl
NotesIf you have trouble remembering the IP address of your Raspberry Pi when you want to access it over the network, install avahi with the command “sudo apt-get install avahi-daemon” and you’ll be able to use raspberrypi.local instead of the IP address.FeedEmbedUnfurl
NotesBecause I don't currently have a real monitor to hook up the computer to, I had to find a way to use it without being physically attached to a screen. Naturally, VNC is the perfect tool for the job.FeedUnfurl
NotesDo you want to remote into your Raspberry Pi and see a graphical desktop? It’s actually really easy. If you don’t want to dedicate a monitor or the TV to the pi but still want to use it, here’s your solution.Unfurl
Notes While the Raspberry Pi packs and awful lot of punch for the price, and it's fairly flexible where HW expandability is concerned, there are situations where you might want a bit more basic digital IO. Thankfully, it's an easy problem to solve with an I2C-enabled device like the MCP23008 (for an extra 8 GPIO pins) or the MCP23017 (for an extra 16 GPIO pins). This tutorial will show you how you can get up and running quickly with either of these chips.FeedUnfurl
NotesThese instructions work for the Raspberry Pi running Raspbian (hard float) and create a hardware optimized version of NodeJS for the Raspberry PI, (and include a working install and NPM!!!)FeedUnfurl
NotesRaspbian is a free operating system based on Debian optimized for the Raspberry Pi hardware. An operating system is the set of basic programs and utilities that make your Raspberry Pi run. However, Raspbian provides more than a pure OS: it comes with over 35,000 packages, pre-compiled software bundled in a nice format for easy installation on your Raspberry Pi. FeedUnfurl
NotesWith the development of GPS controlled drones, far-reaching cheap radio equipment and tiny new computers like the Raspberry Pi, we're going to experiment with sending out some small drones that will float some kilometers up in the air. This way our machines will have to be shut down with aeroplanes in order to shut down the system. A real act of war.Unfurl
NotesDisclaimer: I am not a unix god, and pretty much hacked this together to get working (and it does for me), so a more concise method might appear, so I you do find one let me know, also if you break your PI it is not my fault =] .Unfurl
NotesThe first model of the Raspberry Pi Foundation's low-cost Linux computer will likely be available for purchase later this month. The organization announced today that manufacturing on the first batch is set to complete on February 20.Unfurl
