for an uni project i have to do something with a raspberry pi.
the task is to create a custom linux system with LFS and then to do something. the linux has to be tailored for the use case.
our professor gave us some examples such as a nas, webserver, streaming server, etc. all of this sounds kinda boring so I need good ideas.

my first thought was some kind of lisp machine but i don't know if this is enough work for the project. to be honest i am fairly new to lisp and would use this project to learn more about it on the side.
any thoughts on this idea or other ideas?

Accommodate your pi plus linux for weather balloons. Probes are awesome, and pi is cheap enough in case its lost. Fit it with some caching file or something so that it could handle power failures. Add RTL SDR support (because USB), add rtl_power so that it could monitor wide range of frequencies, osmoSDR for recording and monitoring. Pi has GPIO pins - so many sensors to hook in there. I'm pretty sure there is a lot of GPS software too. Add camera and automatic imagery, scheduler. Call it ProbeOS or, I don't know, SkyhookOS. You got the idea.

I like your idea. Don't know how it is elsewhere in the world but here in germany the assholes of people in charge get as tight as a 7 year olds when it comes to spending money. no way anyone would take the risk of losing 100€ worth of hardware for a student project. i won't even think about the legal issues of starting a balloon (air traffic is quite near)

It can be retrieved if fitted with parachute:

Anyway, you can make weather station on the ground. Measure pressure, wind speed, temperature. Or solar flares via amp and VLF antenna (people even record Schumann resonance). Store or feed data on LAN/Internet.

Something like networking service is indeed boring. Maybe home electronic center a.k.a. smart house, for turning lights, appliance, etc.

Do you need to demonstrate its use? If not you can just build the OS as if you have all the hardware, when in reality you don't.

no i could feed it with dummy data.
i would prefer something usefull because then i only have to buy a pi2 after the semester and can use my system.

weather station is a nice idea. i will look how much the hardware would cost tonight.

Make it into a floating radio station.
The Raspberry pi can transmit FM a surprisingly far distance. Look up PiFm by the Imperial College robotics club for the source code. Then just put it on a balloon and let it fly around, broadcasting glorious pirate radio until it crashes into something.
