I have a Raspberry Pi 5 8GB with the active cooler but I'm having trouble getting my one game (Pokemon XD/GAMECUBE) to play reliably. I have dolphin downloaded and I can get the game to start but it will crash without fail every time. Sometimes 1 minute into playing, sometimes I'll get 10 minutes. Do I need to have something additional downloaded besides Dolphin? It will play at 60FPS, VPN 100% and then seemingly without any sort of pattern, it will drastically change. Sometimes down to 17FPS, VPN 15-30%. Any help would be appreciated. I am pretty new to SBCs/microcontrollers/etc and I'm looking forward to learning about coding and circuitry. I feel like I'm probably just missing something simple, but it's got me beat.

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

In general, from making cyber decks, building premade kits to homelabs to full on actual engineering work,

What would you want to change in the process of making?

This could be picking & getting parts, assembly, programming, or just anything.

Hi I recently saw that the Pi 5 just came out so I would like to know if it would be a better idea to have a RPi with a NVME base as a home theater or a SFF PC

All I do is watch downloaded series or movies on vlc or netflix/disney +/crunchyroll/youtube or torrenting at first I wanted to download Yuzu but I modded my switch so I don't need an emulator anymore

Should I invest in a PC for the better performances ?

Has anyone successfully interfaced a Raspberry Pi with an old stereo amplifier's circuit board to capture and replicate control signals for internet-based remote control? And maintaining functionality on the physical device with realtime update to the Raspberry Pi?

That would be a great way to enjoying old technology with new, would it not?

I have a Raspberry 3B+ where I installed RetroPie, which is connected to an LCD via DSI, and when I want to connect it via HDMI to a TV, I have to disconnect the flat cable, otherwise it stays permanently with a rainbow screen. Is it possible to have them both connected simultaneously? Any help?

Hey guys, i need some help with software choices. I need to manage/monitor an industrial ventilation unit. When this device stops working or if there is a problem i want to show it on an webapp. For the prototype i used an raspberry pi connected to the normaly open alarm output from the ventilation unit. The rbp checks this output and when changed it sends an email to the technician. This works but i want to develop it further by using an webapp with live monitoring and logging.

Also i have a new project, i need to monitor 30 fire valves in the ventilation. I need to know the currents states from all the valves. I am planning to do this with an raspberry pi and a gpio expander.

I want to build an simple platform for both things and maybe in the future more.

So i need: User control, an protocol that connects the Smart Signal monitoring device to the webapp and an protocol for the raspberry pi to the webapp. I think mqtt and api. I want to have 1 server that runs the webapp and i want different users etc.

Hello guys, Am using raspberry pi 5 and I already installed arduino IDE on it but every time I try to open it, it doesn’t open. Can anyone help ? Note that it got installed using sodu

Hi! Ive been looking for alternative programs for image processing/object detection. Any suggestions of applications that is easy to use and reliable on the data/accuracy of the object detection??

Is it possible to detect objects in real time by using raspberry pi 3b+ and camera module v2. Might need it for project especially for object detection. Will it run smooth or no?

Hi! I want to build (well, more accurately, my daughters wants me to build) a Minecraft server. My daughter would like to be able to invite her friends (two or three of them) to join her on this server from their houses.

I understand the basics of assembling the server and even opening it up to the internet, but I want to be sure it's safe once I forward ports. I've done a bunch of Googling around, but have received mixed information about how best to protect the server from malware, infiltrations, etc.

Can anyone point me to a good, authoritative source or, better yet, walk me through best practices?

Thanks!

I have been building tablets and phones based on the Raspberry Pi, but don't know where to market them.

I see posts on various forums, including reddit, where people have a hard time finding simple, non-cloud devices. Some of the projects that I have built using the Pi can fill that niche... but where is the marketplace for people who value non-enshittification? Amazon and ebay are too general; people who are looking for good devices have no reason to search there.

Any ideas?

I am doing some tech for a conference with 4 parallel sessions, and I am required to record every session in order to produce videos later. I already have a means of recording the video and audio, but I would like to record whatever the speaker shows on the projector screen so that I can simply include that in the video. (Otherwise, I have to manually sync up PowerPoint slides to the video in post production, which is tedious and time-consuming.)

I've picked up & tested 4 capture cards that successfully capture the projector screen as 1080p. If possible, I would like to avoid buying 4 laptops just for the purpose of recording the video feed using OBS. Is this something that I could accomplish with several raspberry pis? I have never worked with a raspberry pi specifically, but I am reasonably competent with electronics.

Alternatively, does anyone have any better suggestions? If buying a laptop for each room is unavoidable, any tips on minimum specs would be appreciated.

Hello, this is my first post here. I have 6 RPI3b + that are hooked up to piNoir cameras for video monitoring and are in a custom 3-D printed container that is backlit with IR leds.

I have been trying to use this opensource video monitoring/tracking software developed by a lab, for the last 2 years, but I still cannot seem to run a single experiment without it crashing or losing all my data.

I found a new video monitoring software that I want to try. The developers use a KVM switch with HDMI and USB ports to connect multiple RPI's with cameras to one computer to control each Pi.

The current system (the one that is buggy) uses a router and a server on a PC to control the multiple RPI's.

I was wondering (in terms of connectivity and video capture), which would be better, connecting multiple RPIs via a physical HDMI/USB to a switch or somehow controlling multiple RPIs using a network on VNC (no physical attachments, except perhaps an ethernet cable). Thanks.

Hello, I need your help on our upcoming project that is called 'Automatic Waste Segregator'. For a short explanation, There will be a camera module in the bin and the camera will detect which type of waste is being thrown in the bin. There are three classifications of waste. Biodegradable, non-biodegradable, and medical waste. The camera will detect the waste at a distance and the classified bin will automatically rotated by the servo motor in the drop. I need your help on which Raspberry Pi 5 board that we need to use. Is 4 GB enough for handling real-time image processing? We'll be using Python language as well. Also, what camera module do we need for real-time image processing? Thank you for your answer in advance!

Hello, can i do the same thing this guy did using Raspberry Pi Zero 2 W ?

https://www.youtube.com/watch?v=jlHWnKVpygw&list=LL&index=1&t=416s&ab_channel=NetworkChuck

im working on a arcade game launcher but the arcade breadboard sends hardcoded input to pc.
I made an custom input translater script but now the problem i have is that if the breadboard sends a leftclick input the pc first registers leftclick and then translates it to the desired input causing double inputs.

is it possible to connect the breadboard to my raspberry pi 4b translate it with a script and then send the translated input to pc using a usb cable???

the programming language im using is c# btw

Hey Reddit community,

I've recently got into the world of Raspberry Pi with a Pi 5, 2 Zero W's, and a pico with a breadboard. I'm wanting to start on a project centered around my two adorable axolotles tank. I'm reaching out to gather insights and recommendations from fellow enthusiasts who have ventured into similar fish tank projects.

Here are some specific areas where I could use your expertise:

1. Camera Recommendations: I'm in search of a camera that supports auto-focus and offers decent low-light performance, ideally one that seamlessly integrates with libcamera. Any suggestions or experiences to share?

2. Live Streaming Guides: I'm contemplating live streaming from the Raspberry Pi setup. I have my own domain, but I'm also considering streaming directly to YouTube. What are your thoughts on the best guides for achieving smooth live streaming from a Pi?

3. Sensor Setup: I'm interested in monitoring parameters like pH, temperature, and possibly others in the axolotl tank. What sensors do you recommend for these purposes, and how did you go about setting them up with your Raspberry Pi?

4. Lighting Control: Currently, I have basic lights for the tank, but I'm looking to enhance their functionality by programming them or exploring other lighting options that can be set up on timers. Any advice or recommendations on programming lights with Raspberry Pi or alternative lighting solutions?

I'm eager to hear about any tips you all have for undertaking this project. Your contributions will be immensely helpful! Thanks in advance for your help!

This might be a bit weird but we're not allowed to buy a complete product. We have to buy parts or components. So we're allowed to buy an IR module and tape it onto the pi, but not buy a camera with that exact same sensor onboard. The line seems a bit... Dubious imo.

We want to film things in the 1300nm range. It seems like it might work all the way down to 800nm but the results get pretty iffy, so we want to get as close to 1300nm as possible. I don't know enough about cameras to say how much sensitivity for that part of the spectrum is needed though.

I did some research and the pi modules without the IR filter (NoIR) come close-ish. They seem to top out at 800nm which barely meets the minimum we'd like to hit. Are there any other sensor modules that do better?

Edit : It seems like silicon isn't capable of doing significantly more than 1000nm. So I guess we'd be looking at exotic (and therefore more expensive) hardware. The current budget is a hard cap of $500, lense and peripherals excluded.

I am using an arduino pro micro for my controller in the handheld console, my computer for the console is a Raspberry pi 4b.

I have an arduino controller that I will use in the handheld, which has 14 buttons and 2 joysticks, which I got to work perfectly fine with my windows pc.

When I connected it to my rpi and when to the retropie configuration settings, the buttons configured perfectly, but the joysticks did not. Again they work fine on my pc but don't work at all on my rpi4.

I have the joysticks range set to this:

xAxisValue1 = map(xAxisValue1, 0, 1023, 0, 255);

yAxisValue1 = map(yAxisValue1, 0, 1023, 0, 255);

xAxisValue2 = map(xAxisValue2, 0, 1023, 0, 255);

yAxisValue2 = map(yAxisValue2, 0, 1023, 0, 255);

I want to mention when I change the (0, 255) to (-32767, 32767) the joysticks start bugging, where the x axis gets maxed out, and just refuses to work properly. I tried to us jscal which is after I changed the range back to (0, 255), which gave me this information:

when centered:

Axes: 0: -27723 1: -32767 2: -27039 3: -27296

when moved left for both joysticks:

Axes: 0: - 32767 1: -32767 2: -32767 3: -27296

when I move right for both joysticks:

Axes: 0: -16449 1: -32767 2: -16449 3: -27296

when I move up for both joysticks:

Axes: 0: -27723 1: -32763 2: -27039 3: -32767

when I move down for both joysticks:

Axes: 0: -27723 1: -27296 2: -27039 3: -16449

Mapping the joysticks in the retro pie configuration produces no results, as it just goes to "not defined" as if I skipped the mapping.

My guess is that I need to set the range, but when I set it to (-32767, 32767) the joystick glitches out on even my laptop as well.

I used a serial monitoring code, and found that my maximum joystick values are 0 and 1023 for both axis and joysticks, which is the limit for an arduino.

I also want to mention, before calibrating my joysticks on windows, the joysticks even when moving the joysticks to the maximum and minimum, the app "setting up a usb gamepad" it shows that it only takes up half of the box even when rotating the joysticks fully, after calibration there is a full range of motion for both joysticks, so that might be a clue. I have spent hours of my weekends trying to resolve the issue and modifying the code, but I just don't have the knowledge to figure it out.

TLDR; I have joysticks connected to my arduino for a custom gamepad for a handheld console, it works on my windows pc, but doesn't on my raspberry pi.
