I own a bar and i always wanted people to see a web page when they connect to my public wifi. I was wondering if it's possible to build my own wifi hot spot using arduino and after the webpage appears users can connect to internet. Is there a shield i can use or it is eaven possible? I guess it could be a cool project
Yes, an Arduino could. but it would be more expensive and less functional than a hack-able router, running linux.
And the available Ethernet shields for Arduino only allow a very limited amount of connections at the same time.
any example of a hackable linux router ? or tutorial in witch i can achieve such a functionality ?
Look at OpenWRT or Tomato for examples.
