Bjorn Cyberviking
Hardware
It's a Pi Zero W with a waveshare e-paper screen. See Pwnagotchi
If you want to run Bjorn on different Pi's there is https://github.com/HackCocaine/BjornCocaine - it also extends functionality but I don't know exactly how.
General Setup
See Pi_Zero_W
Setting up Bjorn

USB Networking
This guide explains how to configure USB networking (usb0) on a Raspberry Pi Zero W using NetworkManager, so you can stay connected via SSH or a web UI even when switching WiFi networks.
I had the problem where the otg would stop working if I switched wifi connections on Windows.
This as I said let's you stay connected to Bjorn if you use http://bjorn.local:8000/ or if you ssh into bjorn with ssh bjorn@bjorn.local

Using Bjorn
Connect to WebUI over Wifi using http://bjorn:8000/
Web UI Explanation
NB if you change settings you have to press the Save button in the menu above :)
The buttons in the UI show the status, they are not necessarily instructions :)
You can see what it is doing by selecting the Playground (top left) and clicking on the red "OFF" button.
Addon Modules
https://github.com/LOCOSP/BjornWpaSecHarvester - download and process Wi-Fi network data caputered by Pwnagotchi, processed with wpa-sec, and inject the networks into your Bjorn system. Additionally, it integrates with Discord to optionally send the collected networks to your server
