USB rubber ducky that gives you an administrator command prompt and automatically executes commands, but made on a default teensy 4.1. (Probably works with any teensy that has SD support)
Create a commands.txt file on your SD card, each next command seperated by a ;. This can be changed in the code.
development is currently halted due to being busy, i've made this public so that i'll eventually be forced to finish it. (no, it doesn't work (sorta) right now.)
