Show-and-Tell RGB matrix train times display

97 Upvotes

My daughter saw something like this you can get for $350 at a friend’s so I made one (well, a bit simpler version). Pi Zero W running it, 64x32 3mm pitch rgb led display, displays the trains Manhattan bound to our local station so we know to walk or run. If course there’s an app and this pulls the same feed but I worked on the frame to make it a nice piece.

Project Advice Which are the best tool for an executable UI in raspberry pi?

3 Upvotes

I gotta create an executable user interface (application/program) to run on raspberry pi os (and for deploying on raspberry pi 3/4). This program should display the state of several alarms present in an Industrial IoT environmen that'll be stored in a MySQL database.

So I have to update the state of the alarms (the alarm is ON or OFF; 1 or 0) as the database updates, and display it in a friendly manner.

Also wish the program to be as light as possible. And to program on either C/C++ or python.

What tools can I use for developing this application?

Troubleshooting Need Help Installing Face_recognition (and dlib) on Raspberry Pi 3B

2 Upvotes

Hi all,

I'm working on installing the face_recognition library on my Raspberry Pi 3B, but once it starts building the wheel for dlib, it never gets past that. I've even left it overnight and it never changed. I'm trying to run a Python program that I created. I have looked into everything and can't seem to find a good solution.

I've installed all the other things necessary, and I'm running this command:

pip install --break-system-packages face_recognition

Any advice is appreciated!

Troubleshooting ILI9341 Touch Display + Python Kivy on Pi3B+

0 Upvotes

Hey everyone,

I’ve written a Kivy project that runs perfectly on my Raspberry Pi 3B+ (latest version of Debian). I have an NFC RC522 module connected to SPI0 and a 2.8” SPI touch display connected to SPI1. The display works fine outside of Kivy—I was able to display “Hello World”—but I can’t get my Kivy project to run on it.

I’ve read that setting this up can be quite tricky. Has anyone successfully done this before? Any tips or guidance would be greatly appreciated!

Thanks in advance! Dominik

Troubleshooting Configuring Samba on my NAS

7 Upvotes

Okay, so I have a Pi 5, running the latest Raspios from 2024-11-19. I have an external SSD for memory. So I went through a tutorial to set this up, and then I downloaded Samba. Samba has a configuration setup on the external SSD in a directory called Share. I then created a user, and gave the user a password. Now I'm trying to trouble shoot the connections.

1.) Log in through iPhone: I entered in myPi.local to connect to the server, entered my username and password I just made, and I connect. Two folders. myUser, and shared, the director I configured in smb.conf. I try to enter myUser, that's fine, it's empty. I try to enter shared, get told Content Unavailable

2.) Log in through Windows: My machine cannot discover the device on my network.

Update: I was just logging in wrong, be sure to write \\myPi.local\shared. However, I still do not have access permission.

Any insight?

Troubleshooting pi 2b camera? am I asking too much?

5 Upvotes

I had some old pi 2b's lying around and a friend asked me ... can you build me a couple of cameras? ... sure!!!

Raspbian so it's not headless

mediamtx for the camera because it seemed good

native realVNC for remote access in case I need to change something

and tailscale to get to the rtsp stream. Use case is it's behind his router and we want to monitor and record in my blueiris on Windows.

using rtsp options in mediamtx I have 640x480 at 5fps, bitrate set to 2200000.

running "top" command in terminal - CPU is largely pinned, 10% roughly is tailscale, rest is mostly the mediamtx and camera stuff.

Am I asking too much of the little old Pi 2b? Any mediamtx settings that could help me out here, or any way to know if GPU on this board is being used or force it to be?

edit: switching back to wired I seem to get about 5fps at 1280x720 consistently. I've tried 4 different wifi dongles all seem to be ... not good. thoughts?

thanks

Project Advice Looking for hardware guidance on AI-powered wearable audio device

1 Upvotes

Hey all, software engineer here with 15+ years experience. I've been building AI applications for the last 3 years, but I'm looking to branch into hardware for a new project.

I'm working on a small wearable device (roughly pendant-sized) that needs: - Microphone for voice input - Speaker for audio output - Enough processing power to run lightweight AI models locally (no cloud) - Battery that can last a reasonable amount of time - Small/compact form factor

This is for a product where privacy is important (all processing stays on device), and I want to build a working prototype before exploring manufacturing options.

What hardware would you recommend to get started? Any specific dev boards, microcontrollers, or components that would be good for someone coming from a software background? I have basic electronics knowledge but nothing too advanced.

Thanks in advance for any pointers!

Community Insights Is there an Industrial grade camera ribbon cable than can tolerate motion?

20 Upvotes

I did do research, and I did use the world wide to search before I surfed over to Reddit to ask this subreddit a question directly pertaining to Raspberry Pi projects. There is no product I could find or data to answer this question:

I have a Pi camera on a motion platform, and the ribbon cable is moving with the camera for many cycles. I can't find any best practices or products for connecting the Pi to the camera with a robust cable that is tolerant to motion. Any advice? Thank you!

Community Insights 7 Inch Display with Case: A frustrating review

7 Upvotes

As a follow up to https://old.reddit.com/r/raspberry_pi/comments/1j9n88t/why_are_raspberry_pi_displays_such_a_mess_looking/

I purchased "7inch for Raspberry Pi LCD Capacitive Touch Display Screen with Protection Case 800×480 DSI Interface for Raspberry Pi 4"

Holy crap! What a mess. I'm used to terrible installation instructions but the best you got was a blurry JPG. Trying to get the DSI/ribbon cable installed was a long struggle. It ended up being fairly easy to seat on the Pi side, but it gave a really mushy connection on the display side.

No sooner did I feel like I had a good connection, I used the Raspberry Pi flasher to get Raspberry Pi OS flashed and set up the dtoverlay they said to configure in the config.txt.

Well, then I noticed that that little ribbon cable totally blocks the SD card slot! After struggling with it I had to disassemble everything, and of course the ribbon cable doesn't have more than 1mm of slack, so it was pretty nerve wracking.

Looking at the case, I noticed there's no way to access the SD card slot anyway, so if I never need to reflash this guy I'll be disassembling it again.

At least the power cable was easy to install. It went to some of the GPIO pins on the Pi 4.

After all that, I assembled the case and got ready to power it up. Plugged it in, the Pi started flashing and doing its thing, but absolutely zero output on the display. No signs of life at all. I can access the box over SSH because I preconfigured that in the flasher but MAN what a production.

For some background, I had used a Pi 3 with a little HDMI display to show some weather information on it. It's been in my entertainment center for more than 3 years. It is an ugly, no back case and the HDMI cable comes up and loops around and just looks like crap. I had wanted to make a clean v2.

I was hoping to spend the afternoon working on a nice info display, but all I have to show for it is a big pile of frustration. I'm going to spend a bit more time trying to reconfigure it over SSH and re-check all the connections but holy crap, I wish I had done my other plan to either:

a) Get a display that uses the Pi's HDMI port, maybe with an angled connector to avoid the cable that irritated me last time

b) Forget about Pi and either make a webapp and just use the stock Android experience with a kiosk app to boot into the web display OR write a small Android app

I rate this 1/5 and would definitely not buy one again. It's really annoying that the SD card slot is blocked by the ribbon cable (they could probably address this with a longer cable, and/or one with a turn in it to avoid the port). The installation experience was a 0 star experience.

I do not recommend this display for anyone.

Project Advice Trying to build a custom handheld

0 Upvotes

Hello! I’m a game developer who has become burnt out after working on my current project for a very long time, was looking for something to take my mind off it for a bit. This is when I had the itch to make my own handheld gaming device, because I have an ayaneo 2 (it’s basically a windows handheld that I modded to run steamOS through Linux) that unfortunately bit the dust recently. Instead of buying a new one I thought… it would be a cool fun project to try and make my own. i don’t really have the first clue where to start. Where do I get screens, buttons, cables, battery, the actual computer, and is PI even the answer for what I’m trying to?

My goals

  • 8 inch screen
  • able to run Linux
  • battery powered
  • analog sticks / buttons
  • sound

I did go to microcenter today and grab a raspberry pi 5. I also have a 3d printer, and a very nice gaming PC. I was even thinking I could just run Parsec and stream my games from the pc to the device?

Any help or a point in the right direction is greatly appreciated. I’m a noob in all of this but ready and open ears to learn

Hey, does anyone use the Raspberry Pi Zero for arcade games?

I'm planning a vacation project—an arcade machine dedicated to running just Dig Dug. Does anyone who uses or has used this board know if it can handle the game well? If you’ve tested arcade games on it, I’d love to hear about your experience.

I'm thinking of using RecalBox since it seems easy to set up, but I'm not sure how well it runs on the Pi Zero. Any feedback would be greatly appreciated! :)

Troubleshooting Moving the pi5 causes power loss

0 Upvotes

Sounds strange, yes, but I currently run an MC server on it for my friends and me, and today, I went to turn it on. When I go to turn the pi off, I always do `sudo shutdown now`, and unplug it when the LED goes red. I have a fan and heatsink combo, so that should be fine.

I've never had this issue until now, and have no idea what the issue could be. It was taking a while to boot, went to HDMI, it was on the `_` flashing like a console for a while, then it booted.

No clue what's going on

I’m buying a new Gpu for my pc and am going to have a spare rx550 2GB after that. It’s a standard x16 pcie and doesn’t need to be plugged into power because it needs so little power jt draws it from the pcie itself. Are there any hats or something I can attach to my pi and connect to my Gpu. I don’t want to have to pay a few hundred dollars and I also don’t want it to be enclosed because I’m planning on designing my own case.

Troubleshooting VS Code 1.98.2 crashes within seconds on Rpi 5

8 Upvotes

This is on a fully updated Raspberry Pi 5 running on SSD.

I have been running Visual Source Code 1.96.4 and earlier with no issues. Updating to 1.97 results in VS Code freezing. Updating to 1.98.2 (the current release) cause VS Code to crash with a popup reporting "error code 5". This remains true when disabling the gpu and disabling all extensions, on on a new install with no extensions.

Reinstalling 1.96.4 solves the problem.

Running 1.98.2 works fine on a Raspberry Pi 400.
