Arduino vs Raspberry Pi: Which Is The Mini Computer For You? You’re looking for a small computer to power a laser turret that can shoot multi-coloured balloons – it’s a common situation we all find ourselves in at one point or another – and you’ve heard good things about both Arduino and Raspberry Pi. But you can’t decide – which the best mini-computer for your project? Which is going to prevail as the most useful once you’ve disassembled the turret thanks to that incident with the neighbour’s cat? Which could you play movies on? HDHomeRun Having an HDHomeRun box on your network allows you to watch Live TV directly from XBMC. 1 What is HDHomeRun? HDHomeRun by SiliconDust is a stand-alone networked TV/HDTV tuner box available in two models, one ATSC (American market) model and one DVB-T/DVB-C model (Europe/Australia/New Zealand/Taiwan). You connect the TV antenna cable to the HDHomeRun box and it will scan and tune all channels and, via its built-in network port, the HDHomeRun box will share and stream the channels over a local network using supported clients, such as XBMC.

Replace Google Reader with a Raspberry Pi With Google Reader shutting down this July, you might be looking for another way to stay on top of your feed subscriptions. Why not set up a Raspberry Pi to do the not-so-heavy lifting instead of importing your feeds into yet another web-based service? After all, you never know when anyone (or everyone) is going to pull the pin on their aggregators — especially since RSS is supposed to be dead already anyway. Just follow Conor O’Neill’s lead and install Tiny Tiny RSS on your Raspberry Pi. It’s an open-source app that has been around for ages, and its developers provide a tarball that makes setup on the Pi (or any Linux-powered system) a simple task. Raspberry Pi Do you have frustrating issues with your Raspberry PI Are you experiencing problems with your PI, you can’t explain or figure out why? You bought what you thought where good accessories (Keyboard, Mouse, WIFI adapter and cables), well read on, you may discover your problem is simply the USB cable between the power adapter and the PI.

15 Useful Commands Every Raspberry Pi User Should Know If you’re using a Raspberry Pi computer for your weekend project (perhaps a media centre or a home server) then there is a good chance these useful command line instructions will save you some time. The Raspberry Pi: Yes, It’s Linux You’ve imaged your SD card and booted your Raspberry Pi. You’re probably using the Raspbian operating system and updated and configured it so that it meets your requirements. Watching live TV on a Raspberry Pi using a HDHomerun  UPDATE: I have now got this working all on the Raspberry Pi without needing the ipad -> see this post Getting live TV on the Raspberry Pi has eluded my so far, I have tried various ways and nothing has worked but that was until the Raspberry Pi foundation released the mpeg-2 decoder. The HDHomerun uses mpeg-2 so thought there would be a good chance it should work on the Pi with XBMC. So using the Raspbmc build of XBMC I added the HDHomerun video stream as a source in XBMC and to control the HDHomerun I used an app I have previously tested on the iPad called TV Streamer. The iOS app enables scanning of the channels on the HDHomerun and controlling the tuning.

Images - Raspbian A Raspbian image is a file that you can download onto an SD card which in turn can be used to boot your Raspberry Pi and Via APC into the Raspbian operating system. Using a Raspbian image is the easiest way for a new user to get started with Raspbian. Raspberry Pi foundation Raspbian Images SmartSim, a digital circuit designer and simulator Ashley Newson is a sixth-form student from Oxford. Alex Bradbury and Rob Mullins from the Raspberry Pi Foundation met him at the University of Cambridge Computer Lab open day, where he came over with an SD card ready to show off a demo of SmartSim, his home-grown circuit design and simulation package. It was, said Alex, hugely impressive – I’ve had a play too now, and couldn’t agree with him more. Ashley’s now polished it off and released it for public consumption under the GPLv3. SmartSim running on the Raspberry Pi SmartSim, just to make you feel completely sick about what you were doing when you were 16/17 (me?

Raspberry Pi » The Rantings and Ravings of a Madman So lately, I’ve been trying to use one of my Raspberry Pis as a WiFi bridge. That is connecting the Pi to a WiFi network, and sharing it out via the ethernet port. I was trying to do that with the RT5370 USB sticks that I was also using to broadcast hotspots. With the default drivers in Raspbian however, trying to add wlan0 to a bridge results in this message can't add wlan0 to bridge br0: Operation not supported According the the drivers, wlan0 can’t do it. The only way to add the RT5370 NIC to a bridge is to activate 4addr (4 address frame) mode. iw wlan0 set 4addr on However, once 4addr mode is on, traffic between the WiFi device and the AP seemed to stop altogether. Raspberry Pi : The Unofficial Tutorial Advertisement Get to know the world’s favorite $25 computer: the Raspberry Pi. You’ll find tips, tricks and more in this unofficial Raspberry Pi tutorial from MakeUseOf.

Android Transporter for the Nexus 7 and the Raspberry Pi The Android Transporter allows you to share the display contents of your Nexus 7 tablet wirelessly with other screens in real time. Now, the first tech demo of the Android Transporter is out! Introduction The Android Transporter allows you to share display content wirelessly with remote screens in real time. Please be aware that the Transporter is still a technology study and it is missing the maturity of a full-featured product. However, we think that the Android Transporter is already exciting enough to let you play around with it. GPSd — Put your GPS on the net! gpsd is a service daemon that monitors one or more GPSes or AIS receivers attached to a host computer through serial or USB ports, making all data on the location/course/velocity of the sensors available to be queried on TCP port 2947 of the host computer. With gpsd, multiple location-aware client applications (such as navigational and wardriving software) can share access to receivers without contention or loss of data. Also, gpsd responds to queries with a format that is substantially easier to parse than the NMEA 0183 emitted by most GPSes. The gpsd distribution includes a linkable C service library, a C++ wrapper class, and a Python module that developers of gpsd-aware applications can use to encapsulate all communication with gpsd. Third-party client bindings for Java and Perl also exist. Besides gpsd itself, the project provides auxiliary tools for diagnostic monitoring and profiling of receivers and feeding location-aware applications GPS/AIS logs for diagnostic purposes.

Dr. Monk's DIY Electronics Blog: Raspberry Pi meets Arduino - part 2 I gave a short talk and demonstration yesterday evening at the #raspberryjam event in Preston. I demonstrated the Pi raising some servo driven flags attached to an Arduino. I would have demonstrated communication in the other direction using a ultrasonic rangefinder, but I ran out of time. That can be my next post. Here is the code and details of the electronics for all this.
