GPS tracking August 03, 2012 at 10:26 PM I thought it might be fun to turn my Raspberry Pi into a vehicle tracker. The nearest I got to building a truly bespoke tracker was in 2004 using a Siemens TC45 & later TC65, where I wrote the firmware. There wasn't really anything on the market then to do what we wanted, so we built our own, and I took care of the software side. PrivateEyePi – a DIY home alarm system A big thank you to Recantha for spotting this one: PrivateEyePi is a project that went straight on my “I MUST make one of these” list when I saw it. Right now, that list includes an aerial Pi and camera board with the IR filter removed to take pictures of Iron Age sites in inaccessible bits of Cornish moorland; an Airplay-alike MagicPlay receiver; a garden irrigator and an Ambilight clone for the TV. I need a holiday so I can work on all this stuff – there just aren’t enough hours in the day.
Interfacing with a Wiimote - Physical Computing with Raspberry Pi Difficulty: intermediate This tutorial will show you how to connect a Wiimote to the Pi over Bluetooth. You will then be able to read input from it, including the state of the buttons and accelerometer and send it output, e.g. changing the LED state and playing with rumble. It is recommended to use one of our SD cards or images, if you are not then you will need: python-cwiid and to set your Bluetooth in discoverable mode with sudo hciconfig hci0 piscan. Log into your Pi and start a Python console (or ipython if you want tab completion and other extra features).
Install gphoto2 on your raspberry Via the free software gphoto2 it is possible to connect a digital camera (Canon/Nikon/Olympus, full compatibility list) to your Raspberry Pi in order to remotely take pictures and automatically download them to the Raspberry's memory. Easy case You can install gphoto2 very easily via the command line: [ARDUINO + RASPBERRY PI] Switching light with NRF24l01+ [Raspberry Pi – Arduino ]Lamp Switch[/caption] A month ago we planned to manage our Arduino irrigator (aka Irrigatorino) through the NRF24l01+ wireless module. Our little project has been subjected to a little change, since we decided to make our life easier (buahahah…) and remote control a light over a browser (yes, mobile too). Surprisingly, a lot of people liked the little demo I’ve made with some raw code and asked for a tutorial, so here we are: Ladies and (more probably) Gentleman, I’m glad to present you the lamp driven by a browser switch! Nothing new actually, but still exciting! To test the wiring we suggest you to use the ping/pong test you can find in the RF24 libraries (both, of the raspberry and the arduino).
Ultrasonic Distance Measurement Using Python – Part 1 LEDs, buzzers and switches are the most common items people attempt to interface to their Raspberry Pi’s. Something I found in eBay that is a little bit different is an ultrasonic measurement module. This allows you to measure the distance to the nearest wall or solid object. The modules are easy to buy, cheap and relatively straight forward to interface to the GPIO header. So here is some information on my experiments with an Ultrasonic measurement module and Python.
DIY WiFi Raspberry Pi Touchscreen Camera This project explores the Adafruit PiTFT touchscreen and the Raspberry Pi camera board to create a simple point-and-shoot digital camera. One can optionally use WiFi and Dropbox (a cloud file storage and synchronization service) to automatically transfer photos to another computer for editing. This isn’t likely to replace your digital camera (or even phone-cam) anytime soon…it’s a simplistic learning exercise and not a polished consumer item…but as the code is open source, you or others might customize it into something your regular camera can’t do. Raspberry Pi computer, either the Model B or Model AWith Ethernet and two USB ports, the Model B is usually easier to set up.
Setting up a VM for Raspberry Pi development using Virtualbox, Scratchbox2 & qemu (Part 1) « Executing Gummiworms Last week I released version 0.2 of the Raspberry Pi development VM and I thought that I could safely call it a day because in a few weeks the Raspberry Pi hardware will be available and therefore we will no longer need the VM for software development. So yesterday I announced on this blog and the Raspberry Pi forums that I had decided to EOL the VM and would no longer be updating it as I didn't see the need and i'm not going to have the time to maintain it for the next few months as it takes about 12 to 14 hours to create, configure and upload, 8 to 10 hours of that is uploading using all my upstream bandwidth which is no longer feasible for me to do again until after June. However, almost immediately after posting that I started to receive tweets and PM's asking me not to stop working on the VM or to at least write detailed instructions on how to create your own VM for Raspberry Pi (or other ARM based devices) from scratch.
s Raspberry Pi Lesson 6. Using SSH In this lesson you will learn how to remote control your Raspberry Pi over your local network using Secure Shell (SSH). A common reason for remote controlling your Pi from another computer is that you may be using your Pi solely to control some electronics and therefore not need a keyboard, mouse and monitor, other than for setting it up. It also can just save on desktop clutter, and the problem of having multiple keyboards and mice all over the place. Turn a Raspberry Pi Into an AirPlay Receiver for Streaming Music in Your Living Room I'm in the process of building a portable boombox using the Raspberry PI, while I have not assembled the case the individual pieces work as intended. The RaspPi will do one of three things on boot: connect to my home network, connect to a USB powered portable access point, or create an ad hoc network (ad hoc has had mixed results with iOS and Android devices). It will then start Shairport. Using a USB sound card it will output to a battery powered Lepai TA2020 amp and Dayton B652 speakers. The Rasp Pi and router are powered separately in its own case which will be Velcroed to the inside of the future case so I can remove it and connect it to a home stereo. The router and Rasp Pi get about 4 hours running off 4 Amazonbasic AAs.
Raspberry Pi Wireless Display Using a Cheap Parrot LCD Photo Frame One of the first things I've tried with my Raspberry Pi is to get it to use the low cost Parrot DF3120 320x240 picture frame as a wireless display over Bluetooth. These little frames are available on Amazon for under £15! The basic idea is to set up Bluetooth networking with the Pi, and use SDL VNC viewer to display the X screen on the Parrot. Bluetooth Network Setup learn.adafruit When you buy a Raspberry Pi, it may or may not be sold with an SD card. The SD card is important because this is where the Raspberry Pi keeps its operating system and is also where you will store your documents and programs. Even if your Pi came with an SD card with an operating system on, it is a good idea to update it to the latest version, as improvements and bug fixes are going in all the time.
Turn your Pi into a low-cost HD surveillance cam Local government CCTV is awful, and it’s everywhere in the UK. But I’m much happier about surveillance in the hands of private people – it’s a matter of quis custodiet ipsos custodes? (Who watches the watchmen?) iGuardian - The Home Internet Security System by Itus Networks — Kickstarter iGuardian is the world’s first Internet protection system designed specifically for home use. Almost every day you can read headlines about cyber-attacks or online threats. Cybercriminals are constantly improving their attack methods to become more sophisticated and difficult to detect.
