OK now the fun part! It's time to test your TOR anonymizing proxy. On a computer, check out the available wifi networks, you should see the Onion Pi network
Connect to it using the password you entered into the hostapd configuration file
You can open up a Terminal or command prompt and ping 192.168.42.1 to check that your connection to the Pi is working. However you won't be able to ping outside of it because ping's are not translated through the proxy
To check that the proxy is working, visit a website like http://www.ipchicken.com which will display your IP address as it sees it and also the matching domain name if available. The IP address should not be from your internet provider - in fact, if you reload the page it should change!
Your web browsing traffic is now anonymized!
BEFORE YOU START USING YOUR PROXY - remember that there are a lot of ways to identify you, even if your IP address is 'randomized'. Delete your browser cache, history and cookies (some browsers allow "anonymous sessions") and read https://www.torproject.org/ for a lot more information on how to use TOR in a smart and safe way
