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.
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.
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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
