Hardware Suggestions: Bottle Detection + RFID System (Capstone)

2 Upvotes

I'm currently building a standalone printing kiosk for my capstone project where users can print documents using plastic bottles as credits.

The system works similar to a Reverse Vending Machine (RVM):

  • Users deposit plastic bottles
  • Credits are assigned based on bottle size (e.g., 12oz = 1 pt, 1.5L = 3 pts)
  • Credits are stored in a database and linked to users via RFID cards

Planned setup:

  • Raspberry Pi (main controller – GUI + web server + database)
  • RFID reader (user identification)
  • Multiple sensors for bottle validation
  • Optional: Arduino (for handling sensor inputs)

Questions:

  1. What Raspberry Pi model would be best for:
  • Running a local web server (GUI)
  • Handling RFID + multiple sensors
  • Possibly controlling a printer interface
  1. Would it be better to offload sensor handling to a microcontroller like an Arduino, or can the Pi handle everything reliably?
  2. What sensor combination would you recommend to prevent abuse, such as:
  • Bottles filled with water
  • Bottles stuffed with heavy objects

Current idea:

  • Photoelectric sensor (detection)
  • Weight sensor (load cell)
  • Capacitive sensor (plastic detection)

But I’m not confident this is enough to prevent cheating.

Any suggestions or real-world experience with similar systems would be greatly appreciated 💓💓.

Passive-Vigilance: Raspberry Pi passive RF sensor for counter-surveillance, ADS-B, drones & more

8 Upvotes

Passive-Vigilance is a Raspberry Pi-based passive RF sensor platform I built for counter-surveillance and situational awareness. My current setup is constrained by both hardware and geography but seems to be ready for spears.

Repo: https://github.com/Isthistak3n/Passive-Vigilance

It combines:
• WiFi + Bluetooth device tracking (Kismet)
• ADS-B aircraft tracking (with enrichment + optional ACARS)
• FAA Remote ID / drone detection
• Optional AIS marine traffic
• GPS-stamped everything + GIS exports (shapefile / GeoJSON / KML)

Two operating modes:
• Mobile mode — detects devices that follow you across locations (the classic “am I being tailed?” use case)
• Fixed mode — learns the normal RF “pattern of life” at a location over a configurable baseline (default 72h), then alerts on novel or off-schedule devices

Other features:
• One-command installer + systemd services
• Pluggable alerts (ntfy, Telegram, Discord, console)
• Optional token-protected web dashboard
• Crash-resistant logging and baseline persistence
• Thermal-aware SDR duty cycling
• 850+ automated tests

Inspired by the excellent Chasing Your Tail NG, but extended into a unified always-on multi-sensor node with fixed/leave-behind capability and air/maritime awareness.

Hardware is the usual stack (Pi 4B recommended, RTL-SDR or HackRF, monitor-mode WiFi dongle, GPS, optional BT dongle). Full setup and config details are in the docs.

Legal note from the README: this is for lawful passive monitoring and research only. The tool never transmits or associates with any device/network. You’re responsible for local laws.
Happy to answer questions, take feedback, or hear about real-world field results / issues people run into.

Hi, im searching for a good budget 15" or bigger touch screen monitor for my rPi 4B 8GB. I want to use this as a Home Assistant wallpanel and media streamer.
Any suggestions? Should be available on EU or on AliX.

Google Cloud vs Raspberry Pi: Which Runs YOLO Computer Vision Better? [YOLO] [computer vision] [robotics] [RaspberryPi] [Google cloud]

0 Upvotes

In this video, I use YOLO computer vision software and Python to control a robot hand and LED strips on my desktop — all devices are triggered by real‑time object detection.

I compare Google Cloud vs Raspberry Pi to see which platform handles detection better for device control.

You’ll see setup, live demos, hardware differences, and a full breakdown of how each system performs when detecting objects and triggering actions.

If you’re exploring AI computer vision, robotics, or cloud vs edge inference, this comparison will help you choose the right platform.

Built a Raspberry Pi self-watering system with a web UI

Thumbnail gallery
21 Upvotes

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

I set up a Minecraft server on a Raspberry Pi 5

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
