I know this really isn't the place for that, but I got a Raspberry Pi 4 about half a year ago, and it's still in my drawer, untouched. I had tons of ideas before, none since I got it, anybody has any idea for cool stuff I can do with it?

Put some wheels and like 50 sensors on it. Omniscient bot

I made BT speakers utilizing some old speakers and a pi lying around.

dunno, there are a lot of solutions out there waiting for a problem: automatic plant watering thing with sensors webpage and shit, music center, car music center, full automated coffe machine with EVERY possible setting (pressure, temperature, ratio of different beans,...) and all the services you might want to implement, soap bubble machine (pi might be overkill), voice command party mode (music, fog, lights, laser and shit), oven camera (to watch you pizza or macncheese while returning to desk), flute/recorder speaker (basicly filter input signal for loudest/most importent frequency and let a machine play that on a stupid recorder for you), AI (blockchain, serverless) rubic cube solver (industy 4.0), automatic waffle/microwave cake/... baker

I wouldn't have the drive to do one of those myself, but have fun!

the aforementioned party mode could also have a timer... 18:00: music is rising moving head starts to move the hazer kicks in dns is rerouted to one of those 4k fireplace yt vids

Make a smart home like Jarvis from Iron Man

I just bought https://amazon.com/dp/B089ZZ8DTV/... and installed docker. Gonna use nginx proxy manager and have it as a front end along with other services for my self hosting

Falcon 9 or tesla self driving car clone is a good start 🤞

@24th-Dragon taken a look at adguard?

Make a server out of it! You can't have enough servers

The delimma of an electronics enthusiast. Now you can also make pointless IoT "innovations" ;)

Paperweight. 😉

pihole is cool but when the pi shits itself or the privacy dns server its connected to. u cannot fix it on the phone with cry family members on the other end.

shoulder mounted gun like in predator. have it fire nerf darts.

connect to google glass or whatever.

bonus points: write headtracker to deduce who you're looking at instead of using glass. voice activation to fire it.

@Wisecrack extra bonus points if it's not your own voice in the voice activation.
The head tracker just recognizes certain people and fires if they open their mouth 🙊

(there might be a library for the head tracking)

@Jedidja you could also put a red dot laser on the nerf gun to give users visual feedback of what target their head is pointing at.
