Google AIY Vision Day Camp ⭐⭐⭐
Building
Follow these detailed instructions steps 1 - 66
Pay particular attention to the orientation of the ribbon cables, make sure they face the right way and are pushed in all the way before closing the clamp. Do not do step 66 and insert the microSD card that is in the set.
Powering up first time
Follow these instructions to power up the camera and let it boot. Make sure you see the green light blinking after a few seconds indicating activity. If it successfully starts up, you will hear a beep and the green LED in the front lights up - be patient, the first boot might take a minute or two.
If all starts up well, you hear a sound. After that if the camera detects a face, the button on top turns blue. If it detects joy, the color changes. If you camera does this - success you successfully build the AIY camera 🥳
Connecting to the camera
If the camera successfully connected to the WiFi, you should be able to access it using the link http://orcspi-visXX.local:4664 and see the video stream with a box around detected faces and a joy score from your camera.
For those who cannot wait, the link http://orcspi-vis-XX.local:5555 will connect you to Jupyter 😎
You can also connect to the camera using ssh. On Mac and Window you should have a terminal program. Open is and enter this command ssh pi@orcspi-vis-XX.local - answer yes to the first finger print question, then enter the password (same as in class). You should see a command prompt for your Raspberry Pi where you can enter commands.
Shutting down
The Raspberry Pi is a 'real' computer and just like a laptop or computer it needs to be shutdown before turning off power. Many times just turning it off will be ok, but it has the (small) danger of damaging the file system on the microSD card and not booting again. The proper way to shutdown is
Open a terming and connect to the Raspberry Pi (using ssh)
Enter the command sudo shutdown now
Wait for the green light on the Pi to stop blinking and turn off
Turn off power

WiFi Setup at home
At the camp the AIY camera will automatically connect to the camp WiFi. Once you take the camera home, you will need to configure it to connect to your home WiFi. First get your home WiFi name and password. Note your computer or phone needs to be connected to the same WiFi network as the camera.
Option 1
The easiest way to connect the Raspberry Pi is using a phone and the BerryLan App. It allows you to provide the WiFi name and password to the device using your phone's Bluetooth. This is only needed once to connect to a new WiFi. Here are the links BerryLan App for Android and iPhone.
Option 2
You will need a microSD to USB adapter to connect the card inserted into the camera to your computer. Here are the steps
Remove the microSD card from the camera and insert into your computer using an adapter
The card should show up as a drive called Boot on you computer
Visit the webpage https://play.orcsgirls.org/Pi/wifi.php and enter your WiFi network name (SSID) and password. Make sure everything is spelled correct. Click Download.
Copy the download file wpa_supplicant.conf to the microSD card (Drive Boot)
Eject the microSD card drive
Remove the microSD card and insert into the Raspberry Pi.
This should allow you to connect to the camera at home the same way as we did at the camp. In case of issues, here is a trouble shooting page from a earlier event (sxroll down to trouble shooting). You can email thomas@orcsgirls.org and we will sort it out 🎉
