The Thermal Tweeter needs a wired ethernet internet connection to get tweets. At the Open Hardware Summit and Maker Faire we’ll be lucky to have wifi. Likely we’ll need to use a 3G wireless connection. We need a way to bridge the wireless data services to a wired connection.
Today we picked up a cheap router and tested the setup:
More about our setup and prep below the fold.
If we’re lucky wifi will be usable, but a Google Nexus S smartphone is the backup plan. It can share a 3G data connection as a wifi access point, or as a standard USB network adapter. The USB mode relays a wifi connection if available, bonus.
Actually getting a bulk data plan that will work in New York has been a nightmare. The cheapest option is to buy an AT&T prepaid GoPhone ($10) and use the SIM card. 500MB of internet is $25. We can’t get them here, so we tried to order it to the Maker Faire conference hotel. Neither AT&T’s webshop, nor Walmart’s, seem to agree with that idea. We’ve mapped a few shops to try near the hotel instead.
Internet connection sharing
An old netbook running Windows XP is has internet connection sharing enabled. A couple words on ICS:
We disabled the router’s DHCP server and connected the netbook to a regular socket on the router. That was the magic combination, the Thermal Tweeter prints from wifi and 3G perfectly.
