This is all very much a WIP. I need to go back and document stuff I've already done.

Parts

Raspberry Pi Setup

System Setup

  • Install Raspbian:
    • Installing with NOOBS
    • Download the NOOBS Installer. I used V1.8.0, released 2016-02-29.
    • Unzip the NOOBS package.
    • Download and use SD Formatter to format the SD card as FAT. I named it TIKINOOK.
    • Copy all files from the NOOBS_v1_8_0 folder into the root of the SD card.
    • Eject the SD card and insert in the Raspberry Pi. Hook up the Pi to Ethernet, an HDMI display, and a USB keyboard and mouse, then connect the Micro USB power.
    • When NOOBS boots, check the box for Raspbian, and click Install. Confirm you want to overwrite the SD card.
      • Note: The full Raspbian install probably contains a lot of unnecessary stuff, but I haven't whittled down to exactly what I need for the Tiki Nook. Still, should be OK.
    • Go get a cup of coffee while Raspbian installs.
    • Click OK when done; the Pi will reboot.
    • more to come
  • Use the Adafruit Respberry Pi Finder to connect to the headless Pi over the network and set up the bootstrap process.
    • Launch PiFinder.app (I'm on OS X)
    • Click Find My Pi!
    • Once it finds the Pi, change the Hostname (I use tikinook) and enter the Wi-fi SSID and password, and click Bootstrap!
    • As far as I can tell, PiFinder's Bootstrap did not change the hostname (the Pi remains at raspberrypi.local), and I'm not sure about the Wi-fi either. the other bootstrap stuff seemed to work though? its hard to tell, since the bootstrap terminal window disappears as soon as it finishes, so I cant see if there are any error messages.
  • On the Pi itself:
    • Menu > Preferences > Raspberry Pi Configuration
    • Change the password to something other than the default raspberry
    • Change the Hostname here to tikinook, because the PiFinder method didn't stick.
    • Interfaces > SPI > Enabled
    • Localization > Locale > Country > US
    • Timezone > Areas: US, Location: Pacific
    • Click OK and when it asks you to reboot, say Yes
  • Set up reserved LAN IP address
    • Find the Wi-fi MAC address of the RPi by running ifconfig wlan0. The MAC address is reported as HWaddr.
    • In AirPort Utility, click on the AirPort and then click Edit. Click on the Network tab, and under DHCP Reservations, click the ＋.
      • Description: Tiki Nook
      • Reserve Address By: MAC Address
      • MAC Address: ab:cd:ef:01:23:45 (the address from wlan0)
      • IPv4 Address: 192.168.10.14 (or whatever IP address you'd like it to have)
    • This way, every time your RPi connects to the LAN, the AirPort will give it the same IP address.
  • Set up port forwarding for ssh
    • Not necessary, but I like to be able to get to ssh from outside of my home network.
    • In AirPort Utility, click on the AirPort and then click Edit. Click on the Network tab, and under Port Settings, click the ＋.
      • Firewall Entry Type: IPv4 Port Mapping
      • Description: Tiki Nook SSH
      • Public TCP Ports: 8123 (or whatever port you prefer)
      • Private IP Address: 192.168.10.14 (the reserved IP address for your RPi)
      • Private TCP Ports: 22
    • Then you can connect from the outside by using ssh -p 8123 [email protected] (or whatever your WAN-facing IP address is)
  • Install VNC

Other Libraries

Wiring and Hardware

  • 2016-03-06 - Distributing power along one side of the nook shelves, so that we get better voltage and truer colors to more pixels
    • I don't really think this is working. According to Adafruit "Powering NeoPixels", I need 60 / pixel for max brightness on 294 pixels, which is ~18A. My current power supply is only 10A -- fine for most color work, but for bright white, it's not gonna work. (HAHAHA and my mains circuit is only 15A, so obviously this will work perfectly.)
