Controller:
    create initial Destination (** configurable; MainMenuView by default)
    infinite while loop:
        next_destination.run()
        Destination.run():
            ** Destination._instantiate_view():
                instantiate View
            ** Destination._run_view():
                View.run():
                    do some setup

Configure the SD card on a dev SeedSigner.

Bring the SD card over to a Mac and run:

diskutil list

and identify the name of the SD card (e.g. /dev/disk4).

Unmount the SD card and run dd to copy its contents:

The problem

You want a device, let's call it a BRoku, to route its traffic through your home IP even though it's actually physically located in someone else's house on their wifi network.

The solution

• BRoku connects over wired ethernet directly to a Raspberry Pi (3B+ or 4).
• Raspi connects to local wifi.
• Raspi's traffic is routed to a Tailscale exit node (potentially another Raspi) in your home LAN.

Generate a new airgapped Nostr key via SeedSigner

Create a new key with your own entropy, save it as a standard bitcoin BIP-39 mnemonic phrase and/or SeedQR, then export for use in Nostr.
