My parents got me a .@Raspberry_Pi for #Christmas. Already have it set up as a .@ProtonVPN gateway on my home network. Speeds have more than doubled over using my router to make the connection. #StaySafe
a rasperry pi is a really small cheap computer. ProtonVPN is a VPN (if you think of the internet as a large pipe, t a vpn is a smaller pipe inside that larger pipe to make it so people who might look at your traffic can't tell what you are doing).
Using the pi to make the connection increased the speed of my internet connection over the vpn.
Basically, geeky stuff that ordinary people don't really care about
