The other thing I've been working on is a Pwnagotchi. It's quite easy to set up, just a Raspberry Pi flashed with custom firmware & a screen really. It did take a little while to get it going though. 
Working out how to share ethernet to it via USB, configuring SSH & the display all took a little while. Once that was done, it was pretty much ready to go. I took it around the city & it ate a bunch 
of Wi-Fi handshakes. I've also managed to get it to tether to my phone using Bluetooth so I can manage it from my phone. 

Programming & web access has made huge leaps on iOS, mainly due to the iPad Pro & the fact that both the iPhone & iPad now support USB-C. I was able to SSH into the device, transfer files using FTP & 
view the device's webpage all from my iPhone, which used to be an impossible dream.

Currently, I'm trying to get custom plugins working, but that is proving somewhat difficult. All the files are in the right places, & the config file has all the right options selected, but the 
plugin just won't show up. There is another way to add plugins, by having the Pwnagotchi download them using Git. I'm going to try that next. Hopefully I can get this first plugin working which will 
act as a proof of concept for future plugins I may wish to install.
