Brain On a Board (BOB)

BOB is a test rig comprised of the components of an Unfurl Fern. It was built by samw in feb-mar 2023.

Components

  • A mikrotik routerboard 5 port router/access point
  • 2x Beaglebones
    • One is the standard unfurl beaglebone
    • the second “beaglebob” is used for bob-specific stuff, like running a separate mqtt server and connecting to nodes via esp programmers over usb.
  • A length of LED strip
  • 2x espprog usb programmers
    • Can be connected to any of the nodes for flashing/serial debug
    • connected to beaglebob via a USB hub
  • 1x 24v PSU for the nodes and router
  • 1x 12v PSU for the LED strip

Network

There is a BAN (BOB Area Network) routed by the MikroTik. This includes a BOB-specific wifi network, the idea being to keep BOB-stuff entirely separate and independent of any other airgiants infra, meaning that a) BOB doesn't interfere with any real kit and b) BOB is self-contained and can be taken on holiday to places. The MikroTik

  • MikroTik - 20.20.23.1
  • BeagleBone - 10.20.23.10
  • BeagleBOB - 10.20.23.20
  • Nodes - Dynamic, somewhere in the DHCP range (10.20.23.100-200)
