Determine your Raspberry Pi's IP address with audio

Those of you who use Raspberry Pi computers in a display-free headless mode will know that you need to know the IP address of the RPi on the network before you can tap int with your SSH client. There are methods of probing the network to find out the IP address, however a fascinating solution has been documented by the folks from Interlock Hackerspace in Rochester, New York.

Their method uses a combination of software including a script to run on the Pi at startup to determine its IP address, then pass this to text-to-speech software. And by leaving a pair of inexpensive earphones plugged into the audio socket, you can simply listen for the IP soon after the Pi has booted up. Genius.

To learn how it's done, check out the interesting Interlock website. And for more, we're on facebook, twitter and Google+, so follow us for news and product updates as well.

If you'd rather have a compact video display for your Raspberry Pi - consider our 128x128 pixel OLED Module. With a diagonal size of 1.5" and 16,384 colours to select from, so almost anything is possible. With the extra OLED shield fitting is a breeze. Furthermore there's a microSD card socket, and removable tabs on each side which can hold LEDs and buttons:


And using the module is made simple - we have tutorials and drivers for both the Arduino and Raspberry Pi platforms - great for experimenters or those who use both systems. Furthermore, check out the forum where members are already creating modified drivers to rapidly increase the display speed. For more information including our Quickstart guides - and of course to order - visit the OLED Module product page
