There’s an Easter Egg inside the chumby One (which is now on sale at Costco online for $99, cheaper than chumby.com’s $119 price!) that enables it to work with certain 3G USB modems and function as a 3G router (similar to a MiFi).
Use of the Easter Egg is documented on the chumby wiki, but it can be quite simple:
- Plug in your 3G card.
- Go to the Network Config screen by pressing the top button, going to Settings, then tapping on Network.
- Select “create a new connection”, press OK, and wait for the scan to time out.
- Select “Other”
- Enter 3G as the name of the access point. It must have a capital G for it to work.
- Wait for the subsequent scan to time out.
- Select “Manual”.
- Tap “OK” to select None as the encryption type.
- Tap “OK” to select Automatic IP allocation.
- Tap “OK” to confirm settings and connect to the network
To activate local wifi sharing, ssh into the device (or plug in a USB keyboard to activate the drop-down console) and use the command “touch /psp/start_ap” to flag the network setup scripts to configure your chumby One as an access point. Note that AP mode also works with other network sources, such as Ethernet-over-USB.
