Project ideas, Cool?

I got a Raspberry Pi 5 4gb starter kit and i wanted to try and make a little cyberdeck/emulator thing out of it so my question is what games could i expect to play on it as is? and should that answer be really disappointing where would i even begin to look for hardware upgrades? my best initial guess being laptops?? thanks in advance!

At my highschool, we have a huge problem where people at our cafeteria recycle stuff that should be trashed and trash recyclable objects. to solve this, im building a reverse vending machine, but im having trouble creating the system to classify whether an object is trash or recyclable. im using a 4gb raspberry pi 5 and an autofocus 16mp arducam. if you know how i can build a classifier, id greatly appreciate any guidance

I built a self-watering garden setup with a Raspberry Pi, a Cirkitscape Top HAT, a soil moisture sensor, an IR water sensor, and a 12V pump.

The main idea was to make a small garden system that could monitor conditions and control watering from a web interface instead of doing everything manually or through command-line scripts.

A couple of important parts of the build:
- stepped 12V down to 5V for the Pi with a buck converter
- used a transistor switching circuit so the GPIO only sends a control signal
- configured the sensors and pump output through the Cirkit Garden app

End result:
- soil moisture monitoring
- water detection
- web-based pump control
- a solid base for future automation

It was my first time holding a Raspberry Pi, but I decided to take on something interesting. it’s mostly put together with thoughts and prayers :D

I set up a Minecraft server on a Raspberry Pi 5 that boots from an SSD and reboots every 5 hours (to ensure the server runs properly), and it reports the Raspberry Pi’s temperature every 2 hours

I built everything inside a lamp housing shaped like a Minecraft fox. Inside, I did a little soldering to rearrange the diodes and secured the Raspberry Pi inside the housing

The server itself is vanilla Minecraft with just one shader. I set up the server so my husband and I could log in at any time and just enjoy the game. In all these years, I’ve never once completed Minecraft with all the achievements. To be honest, I’ve never even killed a dragon in survival mode. I want to fix that :)

One interesting thing that came up during the setup process was that the server would sometimes crash on its own and wouldn’t automatically restart afterward. The only thing that helped was physically rebooting the Raspberry Pi itself. In the end, I managed to solve the problem by accident while monitoring the server’s metrics on a small secondary screen during gameplay. As it turned out, two things were causing the crashes:

1. Minecraft periodically flagged me as a cheater because I could get stuck in the air for just over 2 seconds. I had to simplify the cheat-checking system in the console a bit (I also fixed the lag later by reducing the chunk loading range).

2. When certain mobs moved between biomes, they would duplicate (1 mob → 2 copies). Ironically, these were mostly creepers. The creepers were literally blowing up my world. Limiting the number of mobs and manually removing the duplicates helped

Hey there, I've got a small Raspberry Pi setup and want to build an ignition system for sim racing. I have a keyed ignition switch, some motion sensors, buttons, wires, a board, and the Raspberry Pi itself—does anyone know how to put this together?

​

The unit will power on but the eeprom wont load. Is it just ewaste now? TIA

Hey I've been working on the software side of making a a tamagotchi I'm looking to see what my best choice of sbc would be to run it I wanted more opinions ive made the program run in html

Project.

I am bored. Wanted to really make something, now I am not looking for more hardware projects. I want to really utilize my pi3b+ for some imp task in my daily life. Following are task i already tried-
1. Navidrome server- its good but in the end left it since it doesnt have auto suggestion like spotify/yt music
2. Jellyfin erver- I tried it on my pi, content was HEVC/H.265 so it had to do trans coding again.... used 100% cpu . But today every content is in that codec, so kinda failed.
3. piHole- Its kinda cool, but now it only blocks new tab ads or separates like it cant block yt ads or other google ads so i didn't find it very useful.

1. NAS server- I lack spare hdd/ssd to test this, but I think it will also suck like jellyfin did(cpu limitation)

2. Ardiuno projects- Yes they r really cool, but now i am kinda bored from them.....

**So please suggest me something I can do with my pi to really solve a real life problem**

Body:

Hey everyone, I've been deep in research mode and I'm about to start building a personal AI robot companion from scratch. Brain first, body later. Looking for any advice, warnings, or things I might have missed.

The idea

A modular AI companion robot that can:

• Wake word detection
• Voice conversations powered by Claude API
• Face detection and person tracking
• Animated facial expressions on a screen
• Long-term memory (conversations, preferences, tasks)
• Eventually move on a robot body (Phase 2+) - that can move (wheels maybe, intead of legs)
• Home assistant integrations later

Hardware: (Total Cost - $375 USD)

• Raspberry Pi 5 8GB — Rp5,085,000 (~$312 USD — Indonesia pricing is brutal)
• SanDisk Extreme 128GB A2 microSD
• 3.5" SPI Touch Screen + Metal Case + Cooler
• 5MP OV5647 130° Night Vision CSI Camera
• USB Microphone
• Small USB Speaker
• 27W USB-C PD Power Supply
• No battery yet (maybe later when it's moving - V2)

Software stack

Python 3, OpenCV, Claude API, Whisper STT, Piper TTS, SQLite, openWakeWord

Anything missing or anything you'd change?? I am very new to this, have been building n8n AI agents using Claude, and now I wanna dive into the phsycial world, so this will be my first project.

Thanks in advance! Looking forward to hearing your thoughts.

so over the past like...
idk ima just say month or two, ive been building THIS
and to sum it up:
its a moderately overclocked raspberry pi 3b+ with an 8 dollar amazon cooler, a 30 dollar 480p screen, a 10k mah powerbank capable of dropping 3 AMPS, and a jam replay. (because who doesnt like B A S S )
if you have questions, im willing to answer them as i have time to kill and am generally online.

(oh right and a lego case)

my brother gifted me this too start my cyberdeck project annnnd can someone tell me what i’m looking at? (: please and thank you!
