I have this raspberry Pi 4b for some time now for uni projects, but tinkering it with a bunch of cables connected to the most basic of devices (monitors, mouse, keyboard, etc) was messy as hell.  And with the specific parts (micro HDMI adapters and portable monitor) just laying there, I have decided to make a starter pi kit that allows the user to carry the board anywhere and tinker it without needing to find a pluggable monitor and massive keyboard while retaining most of the pi's functions, ie GPIO pins and USB and LAN ports by kit bashing components from other previous projects that were left alone in my room.
