Raspberry Pi Project for barn surveillance
Key points:
- Remote barn (1km+) with no internet, only mobile.
- 2 entry points: door && gate.
- Detect intruders -> send SMS/call && send video to a remote server.
Setup:
- Raspberry Pi 4 or 5.
- Door sensors (Zigbee/LTE)
- Night camera
- GSM/LTE-M module
- BLE/Zigbee button
Life cycle:
Shutdown detection on off-hours (hours where there's no need to act upon detection). Generally, between 7 am and 7 pm.
When movement is detected by the BLE/Zigbee sensor, the Raspberry Pi should receive the notification and then in parallel do the following:
- send an SMS message/make a phone call to my mobile phone (or my parents)
- start taking an X-second video with a night camera, then compress the video and send it to a remote server that I control
- start playing some siren sounds in an external sound system
Other considerations:
- Local BLE/Zigbee button for system control.
- Remote system stop capability.
Questions:
1. Raspberry Pi 4 or 5? I'm considering at least 2GB RAM for video processing. Is it enough/too much?
2. Small (64GB) M2 SATA or NVME SSD. Recommendations?
3. Zigbee or BLE for the door sensors? The walls to the secondary door have +-50cm thickness and the door is ~8 meters from the place I'm thinking of placing the Raspberry Pi. I've read about some interference between Wifi/USB3 modules and Zigbee but don't know how much of a problem this is.
4. Night camera recommendations?
5. Considering an LTE-M module. Any recommendations?
Appreciate overall recommendations and feedback on the system's design and potential improvements or flaws.

Can I assign a static ip address to a ethernet connected pi using the same router as my PC does?
Hi all, I have a Pi connected to my PC via direct ethernet cable (as in, one end plugged into PC, one end plugged into pi). Is there a way for me to assign the ip address of the ethernet port to use the same router as my pc does? (aka the wifi router). Currently when I try to set a static ip address using the router address it just doesn't work.
I need to do this to be able to ping the raspberry pi from my virtual machine according to this: https://forums.virtualbox.org/viewtopic.php?p=543989#p543989
Relevant info:
Model: 3b+
OS: raspbian
Router IP: 192.168.0.1

Unable to install PyTorch in Raspberry pi 4
Hello,
I am doing an image processing project using raspberry pi 4. I've saved the weights of the model in a pth file and passed it onto a raspberry pi with a usb stick. In order to load the model in raspberry pi so that I can use the camera I need to import PyTorch to load the model weights. The current version of python I'm using is 3.11 and every time I try to install torch it says "package python3-torch has no installation candidate".
Any help on this would be appreciated!

Bluetooth Keyboard Brain
Hi all,
Iām completely new to the world of piās and Iām wanting to build a wireless number pad, with an additional analogue thumb joystick that I can assign each button to a key press (about 20 buttons). I was going to use the pico but from what I can tell there is no way of connecting it via Bluetooth. Is there any other options for a board which will do what I need? A scour of Google and YouTube hasnāt given me any luck!

Trying to Install Raspberry Pi OS on a Kano computer
Hi! Today I tried to install Raspberry Pi OS on the Kano computer. On the box, it said the computer is a Raspberry Pi 3, so I thought it was just a Raspberry Pi 3 with a custom OS, so I flashed Raspberry Pi OS to the SD Card, and so far its been 15 minutes and the screen isn't giving a signal. I'm not familiar with Raspberry Pi, so can someone please help me?

Best framework for app in kiosk mode?
Hello, I was thinking about making a Flutter application that builds for Linux and installs on a Raspberry Pi, but there are some websocket packages that don't work on Linux, only on Android.
I was thinking about using Electronjs to make this application, which one do you recommend?
For development, I have experience in javascript (vuejs, nodejs/, nestjs, hence the preference for Electron) and Flutter.

Use a SD Card or only SSD for NAS?
Hey everyone, my PI 5 will soon arrive. I have also bought a Crucial x9 pro 4TB portable SSD.
I will just use this PI as a NAS with plex or jellyfin. Is it best to install both the OS and store the media on it or should I install the OS on a SD CARD and keep the SSD as a pure media storage space?
What's the best solution to keep it as simple and fast as possible? And of course the longest lifespan as possible.

Processor Scheduling
Having trouble scheduling the processor to perform two long running tasks.
I could simplify this to using the second core, but I am trying to achieve it using a single core chip in the end.

Raspberry Pi 3B+ issues
I have been given a 3B+ from one of my teachers at my school. My goal is to get it running again. Ive tried 3 different os install types (NOOBS, 64bit full, and 64bit standard) and a different Micro sd. It could possibly be a dead Pi but Iām not fluent with Pi boards. I have power to the board, a os on the sd card from the Pi imager software, and still get no sign of life from the board. Power light comes on but activity light doesnāt come on/flash. Iām not seeing any physical damage or burnt/fried parts. Can anyone here help? (Ethernet has been connected and the hdmi cord does work)

Rpi3B NAS HELP!
It depends on how advanced NAS you want. Just installing Raspberry Pi OS and add Samba so you can share files with Windows/Linux/Mac computers is quite trivial, 10-30 minutes work. See https://www.raspberrypi.com/tutorials/nas-box-raspberry-pi-tutorial/
If you wish a more advanced NAS you can pick a NAS distribution and then you get Web management and more features integrated in one place, the Web interface.

Nuanced question about USB/MIDI Controllers + Arduino/Raspberry Pi
I'm no beginner to software, but when it comes to hardware I am mostly an outsider. I enjoy leveraging Pi 4B for various projects, but I have wanted to take on a larger project more recently. I want to make a USB/MIDI controller of various potentiometers, slide pots, buttons, etc. and connect the controller to a raspberry pi with an LCD screen running software that reads the USB/MIDI arduino controller.
My questions are:
1. Can a single Raspberry Pi 4B be capable of running Pi OS on a 7"+ LCD, outputting sound via RCA or 3.5mm output, and simultaneously also read digital/analogue ins from knobs, faders, buttons, and switches and convert them to USB MIDI for software on Pi OS to interpret or would I be better off using an Arduino in addition to the Pi as the usb midi controller handling the inputs
2. How can a Raspberry Pi 4B output sound via stereo RCA and 3.5mm simultaneously? How would I leverage a DAC breakout while still being able to use the 4-pole 3.5mm audio jack already on the pi?
3. In the case that I have both an arduino & raspberru pi 4b, what type of power supply situation would be needed to both power the Pi + LCD and the Arduino? Can I power it from a single power cable?
Apologies if a lot of these questions are naive, I am simply interested in taking on a larger hardware project, but most of my tacit knowledge really exists in software so I'm looking for help, thanks! :)

How to install 3.5 inch display on pi 4?
Hello can someone help me install a 3.5 inch display on the pi 4 64bit pi os? I've already tried the script but it doesn't work:
https://github.com/tux1c/wavesharelcd-64bit-rpi
When I run it the Rasberry pi restarts but the image is not displayed on the 3.5inch display. It just changes from white to black.
