A Whole-Network Ad Blocker, or a Call-Home VPN from Top 10 Raspberry Pi Projects for Beginners
ou can use your Raspberry Pi as a VPN server for free or you can use a VPN service which will limit the amount of data you can use monthly as well a paying a monthly fee. With your Raspberry Pi VPN server you will be able to connect to public WiFi networks and have all your data encrypted which will prevent you from man-in-the-middle attacks as well as any one else snooping WiFi data on the network. When you are connected to your own VPN server you will be able to access all of your home files. If you have movies or music you will be able to access them with ease.

I just built my RetroPie last night, been playing most of the day today.
Another cool project is a Lossless audio player, (this is similar to the web radio player). You can easily buy a DAC for the Pi, (I purchased mine from iQaudIO with a case), and install something called Volumio. This is a native FLAC (and most everthing else), player that with the DAC plays at a really nice quality for the price, it’ll sit on a network/play via internal storage or USB and has a Spotify plug in and also web radio.
I attempted the DIY Amazon Echo project last month, because I love the idea of a digital assistant I can have some control over. I got as far as getting the Pi running headless and connected to wifi... then lost the network connection, spent an hour failing to get it back, and gave up. I feel like I should turn in my geek card. Still, lots of cool projects here, maybe even cool enough to get me to try again.
