There used to be a KS funded case built around a Pi and an HDD that would act as an external storage when plugged to a USB port and would work as Kodi based media player once booted and connected to an HDMI port.
If anybody knows if this can be done DIY style with minimal cable mess I am all ear :).

There’s an Android app for that, it’s one of the biggest things I miss after switching to the iPhone.
Apart from that, great concept: load your 5+ cd images onto your 64+ gb android and be done (win10, ubuntu, debian, grml, kali, bios update cd image, etc) and forget about your usb drive collection...

There are a few of those around.
Does anyone know if any such similar devices are already available? Whether based on an RPi or not?
... build a safe password keeper that looks like a HID device
... do something interesting with USB-based gamepads to map those to keyboard keys for playing old DOS games
... make a connected USB storage device that offers some sort of additional sync services for the data stored on it (maybe over wifi?)
... make a network adapter that also acts as a firewall, or possibly links to tor/vpn/etc
... Something something MIDI over USB
