Hi @Rudy-Trujillo. With sensors you should go for digital sensors that can communicate with the Omega either through I2C or SPI (currently the Omega does not come with an ADC). If you want to use analog sensors, you can also use the Arduino Dock to relay the information back and forth between the Omega and the sensors.
@Vitalii-Korsakov Well, it's not a full-stack Linux environment. However, you can run Node.js on the Onion using the command:
opkg install nodejs
Note, this version it will install is v0.10.5. The V8 engine is still unsupported in this architecture.
As far as getting node packages installed, it is best to install them on your host system (I run a Mac) and then copy them over to the Onion. My approach to this is to perform the install via NPM, zip the entire directory up and upload it to Dropdox. From there, I can perform a WGET on the Onion to retrieve the zip file.
@Rudy-Trujillo @Kit-Bishop is right. I didn't see this before, but the first picture you showed might be wrong:
It says it has mounted /dev/sda as /overlay, whereas it should be one of the partitions under that drive, i.e. /dev/sda1.
You should try to use a partitioning software such as fdisk or gparted to first create a new partition on your USB drive, and then issuing mkfs.ext4 on the newly created partition. That should be able to solve your problem.
Please let me know if you have any other questions.
@Alan-Smith Right now we are still writing a wrapper for the OLED library. However, we do have an older version of a python library for the OLED here: https://github.com/OnionIoT/Python-OLED. However, this library uses smbus, which we haven't had a chance to compile for the Omega yet. If you are feeling adventures you can try to compile it.
