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. 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 Lapse Pi – Motorised Time-lapse Rail with Raspberry Pi Here’s another article in the series of photography related DIY projects using the Raspberry Pi single board computer. This time it’s a Time Lapse rail. In this case, I think it’s OK to start with the results, so here’s a video of a few time-lapse sequence that I’ve put together over the last few weeks. Make sure you play it in full screen, and High Definition if possible! Backgroud Music by So, now that you’ve seen what it can do, here’s how it was done… Oh, by the way, there’s a lot of pictures, so to save load time I’ve split the post across a few pages.
Pi - Let's Make Robots I have: Raspberry Pi, geekroo board, 3-wheeled rc car minus controller from charity shop, assorted bitsnpieces from old toys, printers, scanners etc. like motors, gears, and such,not much knowledge but great enthusiasm. I want to build: A robot. Obstacle avoiding? 10 classic games you can play online - Photo Remember those great games from your youth? They're right here, available for you to play right now. The nifty thing about living in the future, as we do, is that you can play a lot of those games you loved as a kid right here in your browser. See, for example, these ten... Pac ManPlay it here
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: sudo apt-get install gphoto2 If asked, hit enter to complete your installation. Now connect your camera via USB to the Raspberry (don't forget to turn your camera on, in some cases you will need to enable PTP mode on your camera). 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.
Attiny85 and RPI It is wellknown fact that you can use the Arduino as a frontend for the RPI. A simpler and cheaper solution is to use one of the tinys from Atmel, for example the Attiny85. An ATtiny 85 cost about 1-2 $, and no other components are neede. You can use many of the librarys allready developed for the ARduino. The Attiny has among other things 3 ADC pins you can use for analog inputs, like light sensors, temperature sensor, sound etc. You can use the Arduino IDE and a cheap USBasp programmer to program it, or you can use a Arduino with the ArduinoISP sketch loaded.
KindleBerry Pi! I am happy to announce that this article got publish in Hacker montly We left our little studio in the Kootenays last July to travel throughout Europe, traveling to discover about new media, spiritual centers, art, design and open source initiative. I decided to go really minimal on the computer gear stuff, so I only packed my Kindle, a camera, an android phone and of course my Raspberry Pi! Control What Students Can Do with iPad Using Guided Access Functionality April 7, 2014 If not properly used, iPad can also be a source of a major distraction for students. In fact, one of the common thing that happens in classrooms using iPad is that some students take the opportunity when iPad is on to wander off topic and get lost in iPad meanderings. So next time you want to use iPad with students make sure you activate the Guided Access functionality which will limit what students will be able to do on iPad. Guided Access keeps the iPad in a single app, and allows you to control which features are available. Here is a visual guide to show you how to enable Guided Access on your iPad. 1- Find 'settings' in your iPad and click on it
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.
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.
Wireless Raspberry Pi print server Wireless printing has made it possible to print to devices stored in cupboards, sheds and remote rooms. It has generally shaken up the whole process of printing and enabled output from smartphones, tablets, laptops and desktop computers alike. But you don’t have to own a shiny new printer for this to work; old printers without native wireless support don’t have to end up in the bin, thanks to the Raspberry Pi. The setup is simple. With your Raspberry Pi set up with a wireless USB dongle, you connect your printer to a spare USB port on the computer.
