FM Stream Tech Report Published in AKA a beautiful, low cost, carrier grade rack of FM tuners, IP/Internet encoders and broadcasters, using nothing but RaspberryPis, Arduinos, clever electronics, neat mechanics, a shiny aluminium case and lots of passion. SAPO, the biggest Internet portal in Portugal, needed a robust system to tune FM radios in countries like Angola, Cabo Verde, Mozambique and East Timor, where classic broadcast stations are still very popular and in strong demand, even if you're using the Web. So they came to Artica for help. Since then, we have been working in partnership with SAPO, IdMind and André Gonçalves from ADDAC System on a 6U rack solution to broadcast radio signals to the internet. The concept was to have a unit that could be easily installed by non tech people, and placed anywhere on the world to get their local radios automatically broadcasting to the internet.
Speech Recognition with the Raspberry Pi - observing UPDATE: Audio quality is greatly improved by using a sampling rate of 48000 Hz (The default rate is 8000 Hz). So, the commands in step 10 and step 16 been changed to reflect that sampling rate. These are the steps: 1. Start out by installing the Debian Wheezy image on an SD card and boot the RPi with it. 2. FC8 Evo Fanless Chassis The FC8 Evo is the next iteration of our acclaimed FC8 fanless chassis and with it comes a host of improvements and refinements that keeps this chassis on the cutting edge of design and performance. The ultra-efficient heatsink has now been paired with our new direct touch heatpipes for even better cooling performance. The high grade aluminium extrusion is now finished with a fine sandblast texture and the front USB ports have been upgraded to support USB3.0*. Internal changes include easier drive assembly, support for an additional 2.5” drive and a universal optical drive eject button for added compatibility.
Internet of Things. Think WiSmart High quality audio Wi-Fi streaming using the the popular WiSmart EC32L13 module and embedded with Econais audio streaming application software. The Econais WisAudio Wi-Fi audio reference design is an innovative solution using on-the-fly decoding for streaming music and sound. Needing less bandwidth than traditional WAV streaming approaches, while keeping the ability to play high quality WAV audio, WisAudio offers a very high quality sound with MP3, FLAC, WAV and a variety of other audio stream formats. WisAudio is an ultra low power consumption solution using encoded audio due to lower data traffic and on-the-fly decoding by the audio codec. PS3 Eye 4-channel Audio Tests on Ubuntu Karmic The PS3 Eye is a great USB camera for experimenting. It can capture video at 320x240x120Hz, or 640x480x60Hz - much faster than the average webcam. The necessary drivers are built into the latest Ubuntu Karmic, allowing it to work straight out of the box. As an added bonus, the PS3 Eye has a built-in 4-channel microphone array.
Slim Devices On 18 October 2006 Sean Adams, the CEO of Slim Devices, announced that the company was being fully acquired by Logitech. References  Google Play Music Internet Radio (Raspberry Pi and Arduino) I was looking for a project to do with my Raspberry Pi and found this Instructable and thought I would have a go at something similar which worked with Google Play Music. I had a rough idea of what I wanted the final item to end up like and was able to get my dad interested in helping me with the design and construction of the enclosure. All code and CAD drawings can be found in the GitHub repo. Before we begin I should probably point out that a reasonably good understanding of electronics and Linux makes this project a lot easier, especially since my Instructables are probably not the easiest to follow (I do try my best), however feel free to ask if something isn't clear enough.
The-radio The excuse My wife wanted to have a new radio for the kitchen and threatened to buy some ~100 EUR CD/analog radio combo if I don't do anything about it. So I committed myself to come up with something 'infinitely better' for the same amount. How wrong I was to believe that one could simply buy a nice and easy to use web-radio that can play music from our NAS as well as tolerates the occasional ratatouille covered finger. So I set out to build a web-radio on the basis of an old, non-functional radio I once bought on a flea market. It is a German Greatz vacuum tube radio built between 1953 and 1954.
Voicecommand image file and controlling electronics with your voice With the introduction of the Raspberry Pi B+, a lot of people are finding image files aren't working unless updated first. Because of this, I went ahead and made a fresh image file for voicecommand on Raspbian that is A/B/B+ compatible. You can download it at: I've also taken the liberty of putting wiringPi and pilight on it. Raspberry Pi Sinclair TV LCD Conversion I got the idea for this after watching Dave’s teardown of the 1984 Sinclair flat screen pocket TV and thought it looked like a good candidate to make a cool retro style status display housing. So soon after watching Dave’s teardown I headed off to eBay and picked one up, this one was non-functional to begin with (dead CRT) so I had no qualms about gutting it. With the guts and the fresnel lens removed you are left with a nice big space with a nice clear window for the screen. Version 1 – Tiny328 and 1.8″ LCD
Give Your Raspberry Pi Night Vision With the PiNoir Camera The popularity of the Raspberry Pi and compatible Pi 2 models means that a great deal of accessories are available such as the PiNoir Camera and 4D Systems display. The Raspberry Pi and Pi2 are economical little ARM machines which can happily run Linux. The popularity of the Raspberry Pi and compatible Pi 2 models means that a great deal of accessories are available. Downloads – TotalXBMC What Do I Need? If you’re new to XBMC all you’re really going to need is the actual XBMC software and we would highly recommend using the current “stable” build, NOT one of the monthly or nightly builds as these will have bugs and are for testing purposes only. It’s recommended to get used to the basics of how XBMC works and then once you’ve mastered that you may well want to start using some of the other third party applications listed below.
Raspberry Pi Face Recognition Using OpenCV About a year ago, I created a Wall-E robot that does object and face recognition. It uses Arduino as the controller and need to communicate with a computer that runs the face detection program to track the target. Raspberry Pi face recognition has become very popular recently. With the powerful processor on Raspberry Pi, I can connect it with the Arduino using i2c on the robot and run the object recognition program on-board. It could become a truly independent, intelligent Wall-E robot!
