If you have ~50$ and some bandwidth to spare, please consider setting up a permanent Tor Relay using Raspberry Pi.
Tor network has many types of users, including people that live under heavy electronic surveillance (e.g. in Syria, China etc.); with Tor relays, you can help then gain free access to information without fear of censorship and repercussions.
Quote from torproject.org: "Tor is free software and an open network that helps you defend against a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security known as traffic analysis"
A Raspberry Pi is a small computer that costs 35$ from Element14. You can also get a SD card with pre-installed OS that will help you get the relay up and running in 15 minutes. Other things you need are: i) microUSB-charger, ii) ethernet cable, iii) case (plastic, paper, or maybe lego?)
Instead of going through the step-by-step instructions for setting up the relay on Raspberry, here are some excellent guides:
I live in a country with considerable internet censorship, which is especially oppressive towards atheism. I would urge anybody living under suitable conditions, and with spare money, to devote some of their effort to this initiative. It really helps to improve the freedom and security of other people's experience.
