Raspberry Pis are small single-board computers. As I have two of these devices already up and logging solar power production on my roof they could do even more: They are not only supporting a green environment but can also help people from countries with repressive governments by installation of another software package.

Snowflake is a system to defeat internet censorship. People who are censored can use Snowflake to access the internet. Their connection goes through Snowflake proxies, which are run by volunteers.

Setup takes only 2 minutes – full instructions are at kuketz-blog.de

# sudo apt-get install git
# sudo apt-get install golang
git clone https://git.torproject.org/pluggable-transports/snowflake.git
cd snowflake/proxy
go build
nohup /home/pi/snowflake/proxy/proxy > /home/pi/www/snowflake.log 2>&1 &;

and this is the result
