In the previous post, I explained what a MATRIX Voice and a MATRIX Creator is and the difference between the two. I highly recommend you to go through the first part if you are new to it and get a better understanding of the whole project. Great. Now you know what a MATRIX device is and what it can do. Now let us set it up with a raspberry pi This Project is Sponsored by. UTSource is a professional electronic components supplier.MATRIX device is built in such a way that, it will fit easily on top of the Pi.If you turn the device upside down, we will be able to see the female header pins, which can be connected to the male GPIO pins of the Pi. If you are using a camera, connect it to the Pi before connecting the MATRIX. Align the Female pins of the MATRIX to the Male pins of the Pi in such a way that the center of the Pi will align with the center of the MATRIX. Now press them together.Before starting the setup make sure you have npm installed on your PC. Follow this tutorial to install npm on your PC. Once npm is installed, you can install the CLI tool using the commandOnce it is installed, you can create a new account using the commandEnter the account details and finish the registration process. Now sign in to the account usingNow to interact with your device, you will have to register the device to the CLI tool. For that execute the commandOnce it is completed, system will generate a MATRIX_DEVICE_ID and MATRIX_DEVICE_SECRET which we will be using it in the future. Output will be something like. These two lines are important and we will be using it the Device Setup.Download and burn latest Raspbian image to a micro SD card and insert it into the raspberry Pi . Now power it up with a power adapter that can provide at least 2.5 Ampere. Now fire up your terminal and create a password for the user ‘pi’ by executing the commandConnect your Raspberry Pi to a WiFi router or Wired network and make sure it is connected by checking whether it is getting an IP address from the switch. Now perform and update and upgrade by runningNow we can install MOS (Matrix Open System). Now executeThis will install the MOS and all the required dependencies. Once everything is finished, the Pi will automatically reboot. Now go to your home folder and create a file called .envrcHere, paste the two lines with the id and secrets exactly as shown when it was generated, like shown below.Now save and close the file and runNow you can start the MOS. Go to matrix-os folder and run
