Raspberry Pi micro arcade machine - Intro The Raspberry Pi. Love it, hate it, but you'll have a hard time denying the fact that adding an EUR35 1GHz embedded machine to the arsenal of the average hobbyist is a good thing. Recently, I got one of the Pi's myself exactly because of that reason: it's always useful to expand your toolset with something powerful and cheap. I didn't get it for a specific reason other than the fact I may have to use it somewhere in the future and it would be fun to play with it. To make a long story short: Ofcourse I couldn't just be satisfied by just hooking it up to a TV and installing RaspBMC and playing some movies... so I ended up spending quit a lot more time than I originally envisioned.

Setting up LIRC on the RaspberryPi - June 8th 2013 Update: I have completed a soldered circuit prototype, complete with a full parts list and high resolution build pictures. Please read Open Source Universal Remote - Parts & Picturse to learn more. March 9th 2013 Update: I have formalized the schematic and parts list that I’m using and have made it available on Upverter. Please read RaspberryPi IR Schematic for LIRC for more details. March 4th Update: I’ve written a follow up post that describes how to control your RaspberryPi universal remote from the web. Please check out Controlling LIRC from the web for instructions on how to install and configure the software.

“Raspberry Eye” Remote Servo Cam Webcams are a fun and useful tool. Being able to control where they’re looking remotely, though, takes their usefulness to a whole new level. Whether you’re watching your pets while you’re away or allowing friends to participate in an event from the other side of the world, a web-enabled camera puts the end user in control of the experience. Put a Pi on the Web The Raspberry Pi provides a perfect base platform for creating internet-connected devices. When researching how I was going to connect my device to the web, I ran into Make:’s very own Matt Richardson’s post describing how to use the Flask framework to easily create projects for the web on the Raspberry Pi. Rails Assertions Cheat Sheet Last week I was working on the Rails testing book and I started wondering how the rest of the Rails world was writing their tests. Since I decided that I was going to use Test::Unit instead of Rspec in the book, I knew that I could safely limit my search to just assertions and refutions. The first thing I did was identify every method available to ActiveSupport::TestCase that starts with assert or refute.

Arduino LCD avec seulement 3 broches It’s clear that I’ll have to connect an Ethernet Shield, an RFID reader, a keypad and an LCD display to the Arduino, so it’s essential that I make the best use of the available pins. I came across this article which explains how to connect an LCD to the Arduino using the 74HC595 8 Bit Shift Register using only 3 pins. The LCD I’ll be using is a basic black/white 16×2 unit from Proto-PIC. Here’s the datasheet. Here is the little sketch based on the code from the article; I’ve changed it slightly. pifon: an audio baby monitor for two Raspberry Pis « Lallafa's Blog Becoming a dad does not only completely change your life but also changes the scope of your hobby projects (If time still permits :)) My first self-made project made especially for my newborn baby boy Felix is called pifon and is an audio baby monitor realized with two Raspberry Pi devices. the pifon project: two Raspberry Pis converted into an audio baby monitor Hardware The hardware setup is fairly simple: one Pi, the pifon server, has a USB web cam attached.

Adafruit Raspberry Pi Educational Linux Distro This is our second distro, Occidentalis v0.2. Rubus occidentalis is the black raspberry. It is derived from Raspbian Wheezy August 16 2012 We have made a few key changes to make it more hardware-hacker friendly! Version 0.2 updates (new!) cssFx.js - CSS3 property polyfill - It's So Futuristic, Baby! cssFx cssFx adds vendor-specific prefixes to your stylesheets. How it works When the document has finished loading, internal (<style>) and external (<link>) stylesheets are processed, fetching any @import stylesheets as well. It's recommended to bundle stylesheets into one file to minimize request overhead. Once processing is done, a new <style> tag is appended to the <head> with processed properties.
