Raspberry Pi Mini-bots

• ​Raspberry Pi Zero
• Install Jessie Lite ​Raspbian Jessie OS
  • ​Installation instructions
  • ​Setup for USB connectivity
  • Configure your Pi with a fixed MAC address so you don't have to reconfigure windows networking every time you set it up. From ​https://gist.github.com/Gadgetoid/319ecf8e3c5d3660e298, add the following line below to the end of your /boot/cmdline.txt file in your Jessie install. Use a unique pair of MAC address for each Pi. Note there is exactly one space between each term, and the whole cmdline.txt file is one line.

      g_ether.dev_addr=5a:77:1e:af:8e:9e g_ether.host_addr=72:8d:1f:c4:e8:ca
    

• Install Bonjour Services from Apple. This allows your windows machine to 'just know' the hostname raspberrypi.local. See ​Bonjour for Windows
• Connect your Pi to the computer via a USB 2.0 port. On the Pi use the usb port for data and power, not the one on the end (which is power, no data).
• Wait a while while the Pi boots and your USB drivers for the Pi are installed. Once the light on the Pi should be solid green after a while and the driver is installed, continue.
• Set up connection sharing between Windows and the Pi.
  • Go to Control Panel > Network and Sharing Center > Adapter Settings.
  • Identify the name of the network corresponding to the Pi--Its a Unidentified Network, USB Ethernet/RNDIS Gadget. Its probably something generic like "Ethernet 3".
  • Right click on your main ethernet card. Pick Properties > Sharing Tab. Check "Allow other network users to connect through this computer's internet connection, and pick the name of the home networking connection identified in the step above. Click OK.
• Connect to Pi: ssh pi@raspberrypi.local (password is raspberry)
• Configure Pi
  • Setup DNS: sudo nano /etc/resolv.conf

add: nameserver 8.8.8.8

• sudo raspi-config
