I built a media console.<p>Great source of inspiration here-<p><a href="http://www.raspberrypi.org/forums/viewforum.php?f=15" rel="nofollow">http://www.raspberrypi.org/forums/viewforum.php?f=15</a>
I wrote a digital signage system, and had 5 of them around a campus for a youth congress/conference last summer.<p><a href="http://www.streetsign.org.uk/" rel="nofollow">http://www.streetsign.org.uk/</a><p>This year we're doing 7 screens, and I've got two other offices at our company wanting to use it.<p>I've also been using them a bit as test servers, instead of virtual machines (so no slowing my workstation down...).<p>I've also a couple of them (while they're not at conferences) as web displays, showing asana jobs for the team ( <a href="https://github.com/danthedeckie/asana-view" rel="nofollow">https://github.com/danthedeckie/asana-view</a> ) here, in our team room.<p>I've just started helping to set up a friend's one as a time-vault/time-machine for his and his wife's mac.
The Raspberry Pi blog has some good projects to inspire you. I skim it routinely even when I'm not building anything, just because the people who make stuff are pretty creative and interesting themselves.
I monitor the temperature and humidity in my apartment. I used rrdtool for storing the data and HighCharts for generating the charts: <a href="http://pi.tafkas.net/temperatures" rel="nofollow">http://pi.tafkas.net/temperatures</a><p>The process is described in my blog at <a href="http://blog.tafkas.net/2012/10/03/gathering-and-charting-temperatures-using-rrdtool-and-highcharts/" rel="nofollow">http://blog.tafkas.net/2012/10/03/gathering-and-charting-tem...</a>
Nothing yet. Still waiting for inspiration...<p>I have a few ideas that I'd kinda like to pursue:<p>* An LCD display that shows the local transit times, so I know when to head out to catch a bus/train
* An LCD display that shows my weekly mileage (running) and other relevant stats, maybe for other people I follow, too
* An LCD display that alerts me if it I missed a phone call or text.<p>I guess the first step is figuring out how to hook up an LCD to my Raspberry Pi... :)
A temperature sensor for BBQ smokers.<p>Simple thermocouple with an Adafruit breakout board (MAX31855), and an existing Python driver.<p>Also serves up a Nodejs static page that polls for a new temperature every 5 seconds.<p>I'm struggling to find the time to get this going, but it's working okay right now. <a href="https://github.com/CanadaJ/heat-of-my-meat-node" rel="nofollow">https://github.com/CanadaJ/heat-of-my-meat-node</a>
Set up RetroPi on it, ordered some SNES USB controllers for like $7 each.<p><a href="https://github.com/petrockblog/RetroPie-Setup" rel="nofollow">https://github.com/petrockblog/RetroPie-Setup</a><p>I realized all the games are a lot harder than they felt when I was a child. Can't get past the second person on Mortal Kombat 3... but Super Mario World is a lot of fun.
A retro arcade for my kid. There are hundreds of examples.<p>FM Stereo transmitter (I needed a signal to test my rtl2832 SDR indoors).<p>Home automation. This is the only project that has any 'unique' work, the others were just "follow the examples".<p>I'm converting a mobility scooter into a semi-autonomous robot but, nothing impressive to report yet.
My drunk friend kicked in my front door so I took the opportunity to replace the busted strike with an electric strike. A Raspberry Pi controls the relay to switch it open, accessed via a simple Node.js app or text message (with Twilio posting a webhook to said app).
