My guide to opening your home Pi-based web server up to the world using Dynamic DNS. Might be useful to someone - I was trying to get the Raspcontrol project page on my Pi up so I can reboot from elsewhere!   I use ddclient and dnsdynamic.org to do it.   http://raspberrypipod.blogspot.co.uk/2012/07/dynamic-dns-open-up-your-pis-webserver.html     -- Mike ...
Want to build this project? View Parts   In my previous post, I showed how to add a real-time clock (RTC) to Raspberry Pi via the I2C bus.  Another device that is simple to interface with the Raspberry Pi via the I2C bus is the TMP102 temperature sensor.  Technically, its datasheet states "Two-Wire Interface", but TWI can be treated as synonymous with I2C in this context.  For convenience, I bought SparkFun's TMP102 breakout board: Unlike with the DS1307 RTC in my previ ...
Just published a new blog post bringing together everything I've found about determining the Pi's IP at boot time and reporting it vocally over the 3.5" jack using the Festival text-to-speech package..   http://raspberrypipod.blogspot.co.uk/2012/07/headless-raspberry-pi-tell-me-my-ip.html   I've got it so that the Pi vocally tells me it's IP address. During start-up, however, the IP address over wifi takes a while to be acquired, so my script take this into account. ...
Trying to make some time to write a little bit and share the experience with the Raspberry Pi board.   Here is the first article   Enjoy ...
Want to build this project? View Parts   UPDATE: Adafruit shows how to interace with the DS1307 RTC without a level converter in their Adding a Real Time Clock to Raspberry Pi tutorial   Yesterday, I described how to access the Raspberry Pi's serial console via the GPIO header.  Another capability that can accessed from that header is the I2C bus.  I2C stands for Inter-Integrated Circuit and is common serial bus for chips to talk to each other.  Although not written ...
(This is pulled from the Raspberrypi.org blog)    We are pleased to announce the release of our first SD card image based on the Raspbian distribution. This is the result of an enormous amount of hard work by Alex and Dom over the past couple of months, and replaces the existing Debian squeeze image as our recommended install. Notably, it is the first official image to take full advantage of the Raspberry Pi’s floating point hardware for, amongst other things, much faster web ...
Want to build this project? View Parts   The serial console is a convenient way to interact with the Raspberry Pi when a display isn't handy.  From the pinout on the eLinux wiki, I can see that the serial port (aka UART) on the Pi is on GPIO Pin 14 (TX) and GPIO Pin 15 (RX): This serial port can be connected to your computer via a USB to serial adapter.  However, these pins are designed for 3.3V (e.g. 3V3), so some USB to serial adapters may damage the Pi.  The simplest ...
Pi Cobbler for the Raspberry Pi (via adafruit)   Perfect example of finding a demand and filling it.   The Raspberry Pi makes building your own computing projects conveniently simple and has the potential for endless applications. Among its great features, it gives the user a set of 26 I/O pins to use along with I2C and SPI components as well as GPIO and power pins.   To make management of these 26 pins a breeze, Adafruit has released a way to neatly direct the pics into a fam ...
I've been wanting a small portable display for the Pi.  Unfortunately, portable HDMI displays are quite expensive, and the DSI connector is not an option currently as far as I know.  Then I realized that there a large number of small composite LCDs available which are intended for use in vehicles for backup rearview cameras.  I bought this inexpensive LCD on Amazon, the 3.5 Inch TFT LCD Monitor for Car / Automobile by kingsmart for $21.48 (my order was sold by ePathDirect and fulf ...
Howdy,   I had been using the current official Debian "squeeze" image (debian6-19-04-2012) for awhile now, so I decided to try out some of the newer images last weekend.  First off, I tried out the Debian "Wheezy" Beta image.  It includes a great configuration tool called raspi-config which runs at first boot: The expand_rootfs option will automatically expand the image to utilize the full size of your SD card.  I think this is really handy for novice users: The oversc ...
