There is so many cool and fun stuff I would like to do, but there is so little time. For example using a RaspBerry Pi as your own DNS server to filter out ads on all your devices with Pi-hole - Network-wide Adblocking. Or as your own VPN server to encrypt all your traffic not only at home, but also when you are using mobile data with PiVPN.
You can do all three things quite easily on a small device like the Raspberry Pi for about 400 SKr ($30).
Sounds really fun, doesn’t it?
Or am I just geeky?
