I finally found time to play with my Rapiro - Programmable DIY Robot Kit robot (thanks again Element14 for accepting me for this RoadTest!). You can have a look at the review I wrote, but in a nutshell, after having figured out a few hardware issues, I was essentially ready to start hacking and code what I had in mind: I wanted my Rapiro to become an IoT (Internet of Things) device, that I could control for virtually anywhere in the world!

I recently got hold of a Wolfson Audio card and did a bit of trial recording using the command line - see http://www.element14.com/community/community/raspberry-pi/raspberrypi_projects/blog/2014/04/06/wolfson-audio-project. That all works fine - but what I want to be able to do is use use my Pi as a mini-recorder, which means operating on its won, away from a monitor/screen/internet connection, etc. I decided that, as I have a smart phone with a browser, if I could create a network connection b ...
This article assumes that you have already successfully installed your Wolfson audio card - if you haven't done that yet, there is an excellent blog by cstanton at http://www.element14.com/community/community/raspberry-pi/raspberry-pi-accessories/wolfson_pi/blog/2014/03/14/can-you-hear-the-wolfson-calling-setting-up-and-using-the-wolfson-audio-card Once you have your card set up you will want to start recording with it. Like may people, I run my card 'headless' via a Putty shell, ...
I have recently set up a LAMP Raspberry Pi and am using this at work to monitor some servers (see Raspberry PI as a LAMP server and PI as a Web Server Monitor) I'm running it 'headless' (i.e. without a keyboard or mouse attached). This is fine until I wanted to reboot it yesterday, and realised that I would have to go through the hassle of opening a Putty session, connecting to the server, logging on, and issuing the reboot command. How convenient it would be if i could just click on a web link ...
