So first set of ideas - Sense HAT related:
1) Upstream the display driver
The downstream driver is referenced, to go upstream it would likely
need to be a tinydrm style driver, there's a number of examples of
those in drivers/gpu/drm/tiny/
https://github.com/raspberrypi/linux/blob/rpi-5.10.y/drivers/video/fbdev/rpisense-fb.c
2) Upstream the joystick/input driver
Similar to the display, there's a joystick
https://github.com/raspberrypi/linux/blob/rpi-5.10.y/drivers/input/joystick/rpisense-js.c
For both of the above there's a dependency on a MFD driver:
https://github.com/raspberrypi/linux/blob/rpi-5.10.y/drivers/mfd/rpisense-core.c
3) A simple python based weather station
The sensors, when enabled using the overlay are available using the
kernel IIO framework. There's a library libiio with python bindings so
it would be cool to have a little mini weather station project, that
could be used with other HATs that have the various environmental
sensors. Options to display this data to a screen/leds such as those
on the sense HAT or to send them out via MQTT would be cool too.
