I'm looking at/attempting to build a little AI assistant using my old RPi 3b. I looked at MyCroft but it seems like it's no longer the best choice.

Ay free open source alternatives you'd recommend?

I want to be able to ask it simple questions like how's the weather etc, but also have it interact with some servos I have and a webcam. I can make python scripts for those but need and AI assistant that I can add those skills to like it looks like you canwith MyCroft

So I downloaded the emulator and ROMs but when I open the game the game crashes than I open the game once again and the emulator crashes any fix?btw I’m on iPhone 12 iOS 17

Hey All,

I am very new to Raspberry Pi, and for my first project I’m attempting to connect my Arducam Hawkeye 64MP to a Raspberry Pi 5 8GB.

I’ve followed Arducam’s QuickStart guide (tried Lite and Full) and a few suggestions from videos/forums, as well. All result in the same ERROR: *** no cameras available ***.

I’m not sure what I’m doing wrong, as I have no idea what I’m doing. I’m hoping someone could point me in the right direction. I’m not quite sure what more info is needed, but happy to provide.

Hello r/RASPBERRY_PI_PROJECTS,

I come to you a project which i am looking help for. (I will try my best to be descriptive) It is a project which adds these to my bike:

• Turn signals (taillight only)
• Speedometer (Acting like a little dash)
• Headlight
• Brake light

After doing some research I found all the parts I need:

• LED kit (for headlight and taillight)
• 3.2" SPI TFT display (mini dash)
• GPS (for speedometer)
• Power Bank (powers the whole thing)
• 3 Position Rocker Switch (controls the turn signals and headlights)
• Micro-USB Cable with On Off Switch (turns the whole thing on or off)
• Limit Switch (for detecting the brakes on both sides)
• Raspberry Pi Pico W (my OG pico broke)

I just need help with power management. I have no idea if this entire setup will fry my Pico W. The 3 position rocker switch is saying: AC15A/250V 20A/125V, on it's page, and I don't want it to fry my Pico. I don't know which resistor to use or where to use them to prevent overvoltage with the LEDs or display. If anyone can help me get started in the right direction, I would be thankful. I have attached some diagrams of what it should look like. (sorry for my crappy drawings)

I would like some tips for coding if you have the time.

If you didn't understand something, leave a comment and I will clarify. (I posted this on r/raspberry_pi too)

Thanks,

u/rkumr

Pi 5 8gb using latest 64-bit/Bookworm/Wayland/Wayfire/Raspberry Pi desktop.

When you try to resize an application window (in my case, chromium-browser) so it extends from Monitor 1 to Monitor 2, it will only display on one monitor. This is by design in Wayfire, from what I have read.

The easiest way to get this to work is by switching to x11/openbox in raspi-config. However, I am having terrible performance issues with chromium and x11/openbox.

So I looked through the Wayfire documentation; there seems to be a plugin named "workarounds" that has an option to remove_output_limits, which you can read about here. It sounds like just the thing I need, but I can't seem to get it to work.

It doesn't help that I have no clue what I am doing.

Is anybody 'round here familiar with customizing wayfire for the pi? Should I be trying to build those "wayfire-plugins-extra"? should I be more focused on configuring the wayfire.ini or the wf-panel-pi?

This seems needlessly difficult, or maybe it's just me.

Thanks.

To begin with, I'm an absolute newbie to all of this. I'm usually a windows peasant and the most complex thing I did with my old Pi 3B+ was setting up Octoprint for my 3D Printer. Since my printer isn't in use atm I thought about trying to make my own little NAS with a few 120GB SSDs I have laying around. I have everything I need together and I already set up the Pi with OpenMediaVault, got the Discs into the system, got Snap raid, but I simply can't wrap my head around how to make it work. I've been scrolling through YouTube, Reddit, GitHub, but I guess I'm lacking at least 5 years of Linux experience to even slightly understand what's going on.

Can someone somehow help me to get this thing to work? Or even better, maybe someone here has a link to a step by step manual on how to set it all up?

Thanks in advance

I have a raspberry pi cluster hat, but I can't connect to the other 4 nodes. I can't even verify if they are on outside of the command : clusterhat on. Other than those lights I can't ping them or ssh into them. I followed this howto: https://medium.com/@dhuck/the-missing-clusterhat-tutorial-45ad2241d738. I'm using the cbridge image for the primary node. The other nodes don't pull IP address either. I have the appropriate images on the other raspberry pi zeros . Did I miss a step?

Can Raspberry Pi 5 Handle My Virtualization Needs?

Hey everyone,

I'm exploring the feasibility of running a specific setup on a Raspberry Pi 5 and could use some advice from the community. Here's what I'm thinking:

1. Base System: Install a debloated version of Windows.
2. Security: Run antivirus and firewall software on this Windows installation.
3. Virtual Machines:
   • VM 1: Host a WordPress website.
   • VM 2: Host a simple database (likely SQL, but open to alternatives).
   • VM 3 (optional): Run Home Assistant OS.

I'm aiming for the best low-power hardware to achieve this. Currently, I have a Raspberry Pi 5 with 4GB RAM, but I'm considering upgrading to the 8GB version if necessary.

My Questions: - Is it even possible to run Windows and virtual machines on a Raspberry Pi 5?

• Are there better low-power alternatives that can handle this setup more efficiently?

Any insights or experiences you can share would be greatly appreciated. Thanks!

Hi everyone, I'm working on a project that involves accessing and processing video feeds from four cameras simultaneously on a Raspberry Pi using the Python OpenCV library. Here’s a quick overview of my setup: Cam 1: Performs both object detection and motion detection. Cam 2, 3, and 4: Perform motion detection only. Observations Memory Usage The memory usage for each camera is as follows: Cam 1: 580 MB to 780 MB Cam 2: 680 MB to 830 MB Cam 3: 756 MB to 825 MB Cam 4: 694 MB to 893 MB Framerate The framerate drops significantly as more cameras are added: Single Camera: More than 3.5 FPS Two Cameras: Over 2 FPS Three Cameras: 0.8 to 1.9 FPS Four Cameras: 0.11 to 0.9 FPS Questions: Maintaining Higher Framerate: What strategies or optimizations can I implement to maintain a higher framerate when using multiple cameras on a Raspberry Pi? Understanding Framerate Drop: What are the main reasons behind the drastic drop in framerate when accessing multiple camera feeds? Are there specific limitations of the Raspberry Pi hardware or the OpenCV library that I should be aware of? Optimizing Memory Usage: Are there any best practices or techniques to optimize memory usage for each camera feed? Setup Details Raspberry Pi Model: Raspberry Pi 4 Model B Camera Model: Hikvision DVR cam setup OpenCV Version: OpenCV 4.9.0 Python Version: Python 3.11 Operating System: Debian GNU/Linux 12 (bookworm) I'm eager to hear any insights, suggestions, or experiences with similar setups that could help me resolve these issues. Note: I've already implemented multi-threading concepts. Thank you for your assistance!

I’m using a Raspberry Pi to transmit FM signals. Can I program a Raspberry Pi Pico to receive these signals and turn on its LED upon detection? I want to achieve this without any additional components, just the Pico and a piece of copper wire or a similar material. I don't need to decipher the signal, just need to detect its presence

I just purchased the DF2301Q offline voice recognition module and want to connect it to me Raspberry pi to use the voice command to turn on and off motors etc however I can find very little tutorials or help online how to use it except with arduino. There is very little code examples in the Github repository, some one suggested I write my own python library but I have no idea where to start. Anyone out there using this module that can offer some assistance? TYIA

I just bought a new portable AC unit for my home office. This AC has a water drip to allow the water out of the unit and into an outside drain (in my case, a bucket).

What I want to do is use a Pi to notify me when it is time to dump the bucket.

In my mind, the sensor would go inside the bucket about 4 inches from the top, then when the water level hit the sensor a LED (which would be ran about 15ft to the side of my monitor) would go off notifying me it's time to empty the bucket.

Has anyone done anything like this before? If so, what do I all need?

I couldn't find much on what I wanted to do online, so I came here!

I have a GoPro 12 that allows for Bluetooth microphones. It specifically requires hsp or hfp to work and is not supports a handful of mainly EarPods that work as a microphone. I desperately need the ability to source the audio wirelessly from a 3.5 mm audio jack, so wondering if there is a way to use a pi zero to transmit audio in those specific Bluetooth protocols. Any help greatly appreciated

I built a Simpson's TV from the famous Brandon Withrow guide a while back but was trying to figure out how to turn the "Power Button" into a "Next" button by using a 2pin "Momentary Tact DIP Switch" instead of the toggle switch. I have no python scripting skills and any attempts has "broken" the TV resulting in having to re-image the SD card.

If anyone has any ideas I would greatly appreciate it. Ideally without adding components to the build. Thanks.

Hello everyone, I have installed Android 14 Auto operating system on my Raspberry Pi 4. I have enabled kernel compression configurations, but after building the kernel, the created image is not compressed, and I do not see the active configurations in config.gz on my Raspberry Pi. Does anyone have any idea how to proceed? The project is "raspberry-vanilla".

Hi,

So I'm looking to use my old pi3 b (I think) to basically act as a joystick. The idea is that the thing will be connected to a stream on the website (already figure that out), then with buttons to move it around. When connected to the joysticks it works fine, but I want to use the pi to basically send inputs for the joysticks, so like someone on the site presses the forward button, it gets sent through to the pi, which then acts as the joystick, and like connects the contacts so it can move until they let go of the button. Would anyone have any idea how I could go about this? (The limit of my coding knowledge is from GCSE comp sci, but I was quite good at it :3)

I thought about using servos to move the joysticks but I realised that would be a terrible idea.

Thanks in advanced!!
