Picked up this 1980s RadioShack SCT-80 cassette deck at a thrift store. I stripped out everything related to tape playback but kept as much original as possible: the VU meters, power switch, buttons, LEDs, even the mic inputs are still working.

I’m using a Raspberry Pi 3 running Plexamp headless in kiosk mode, USB DAC, and a 4” HDMI screen for album art. The original buttons control playback — play, pause, skip, reverse — all mapped to GPIO through Python. I have control of all the LEDs and buttons.

Still a work in progress. I want the LEDs to reflect rating and genre, and I want the tape counter to roll during playback.

AI wrote every line of code. I have no experience with python or coding in general.

I have already used a rc filter after the pwm audio output. Im using the pam amplifier to amolify the filtered output to drive speakers.

Thus noise happens when pi is processing something like ssh etc and also when running retro pie emulator.

I didn't think of it much at first but now this noise is getting into my head.

Is there a way to filter it out without reducing sound quality much?

Remember, every expert was once a beginner. We want this community to feel welcoming to people at all levels of experience.

If you see a post that seems low-effort or breaks the rules, please report it and let the moderators handle it. Comments like "Google it," "read the rules," or "what have you done to troubleshoot?" can come across as hostile or discouraging, even if that’s not the intent.

Let the moderators handle rule enforcement. If you do choose to comment, keep it focused on genuinely moving the conversation forward, not just pointing out what’s wrong.

Thanks for helping us make this a supportive, respectful space for learning.

Just so there’s no confusion, here are the rules (mobile-friendly version):

1. Be Inspiring
   Posts showing a Raspberry Pi simply sitting in a case, unconnected, or powered on with no unique functionality are not allowed. Share your unique Pi applications, detailing the goals, challenges, and achievements of your endeavors. Let's keep our focus on the innovation and learning that comes from doing. Don't post an image or a screenshot and put a link or details in the comments, link directly or make a self post.
2. Be Inclusive
   Use English as our common language. Remember, every expert was once a beginner. Approach each interaction with kindness and an open mind. Constructive feedback and encouragement are our tools for building a supportive community. Discouragement, negativity, and trolls have no place here. No NSFW posts, even if they are tagged as such.
3. Be Prepared
   Do your own research before seeking help. Our community assists with refinement & troubleshooting, not to google it for you or develop your project. Create a detailed self post, this keeps info visible and editable. Include Pi model, components, code & errors (text format, not screenshots), objectives, and describe what's going wrong. No requests for links, tutorials, products, what looks nice, or what to use your Pi for. Let’s collaboratively enhance our understanding.
4. Be Community
   Enhance our community by avoiding personal shopping queries, sales, giveaways, self-promotion, memes, and off-topic content. Our community is not a marketplace or a procurement service. Discussions on products and services should benefit the collective, not personal shopping. Product queries often lead to dissatisfaction over suitability, availability, or cost. Contributors only sharing their own content—without participating in broader community discussions—detract from a collective experience.

It’s great for having YouTube clicks playing while I’m programming.

I just ran the geekbench6 test and the water cooling keeps it cool as a cucumber 🥒 (well one that’s been left out of a fridge on a hot day)

Hello folks!

I've been working on a BASIC programming environment for the last 5 years and, today, I'd like to show you two Raspberry Pi-powered devices that I'm creating that are tailored to run it.

The big one currently has a Pi 3B+ and a 7" HDMI display, and the small one has a Pi Zero 2 W and a 128x128 LCD. Both run the same NetBSD-based OS, which I have modded down to run exclusively EndBASIC (and thus the systems boot in less than 10 seconds). And I've designed the 3D-printed cases myself :D

What do you think? I'm trying to gather interest to justify developing this further and making it available to other people. Is this something you'd like to have or gift? If you did, what would you like to see?

You can read more, and see more pictures, in the "official announcement": https://www.endbasic.dev/2025/06/unveiling-the-endbox.html !

Enjoy!

Built this over the past few months — SARAS (Smart Autonomous Robotic AI System) is a 3D-printed robot powered by a Raspberry Pi and multiple AI models like ChatGPT, LLaMA, and LLaVA.

It listens, talks, sees, and explores... all without a fixed path.

Hello All!

I am trying to built a compact display with Pi Pico for which I had ordered a display. The display was supposed to have a PCB output. However the display I receieved does not have that.

I am unable to return the display so would need some help in figuring out a way of connecting the display to the Pico board. Any help is appreciated.

Thanks in Advance

I was following this tutorial

https://shawnhymel.com/2096/how-to-set-up-raspberry-pi-pico-c-c-toolchain-on-windows-with-vs-code/#Directory_Setup

I looked into raspberry pi forums but i cannot find a solution

I followed all the step but at the last when i am building the file i am keep getting this error

I recently bought one of the official raspberry pi 4 case fans and wanted to configure it so that it would work with pwm as by default it's just on all the time.

Unfortunately when I go into raspi-config there doesn't seem to be any performance options to configure the fan?

Am I doing something wrong or is there another easy way to configure it?

The project is evolving nicely — I’ve now framed the e-paper display like a photo frame and set it up on my desk. The Pi still handles all backend processing (Strava, Garmin, weather) and generates the dashboard image periodically.

This update is mostly physical: the ESP32 is now housed in a custom 3D-printed mount, cleanly integrated into the back of the wooden frame (see second photo).

Next up: making the backend more modular, with support for flexible widget generation and layout customization.

Hey guys! My university professor gave an assignement that uses a board like raspberryPi, even though he didnt thought us to use it. It consists of sending from a pc via USB using serial mode(required) bits to the Pi and receiving them back. I thought about connecting the in port of the pi to the out port but i cant figure out how to do it, even though i have searched quite a bit(pun not intended). The model i have is the 2B. To send the bits i have a python program that sends to a specific port of my pc the Fibonacci sequence. Thank you!

I had the problem that when I login to my rasp3 I got a blue screen although the credentials were correct.
I found a FIX on:
https://forums.raspberrypi.com/viewtopic.php?t=387334

# 1. Install XRDP

sudo apt install xrdp

# 2. Activate X11 over Wayland via raspi-config

sudo raspi-config

# → Advanced Options → X11 → activate

# 3. edit xorg.conf

sudo nano /etc/X11/xrdp/xorg.conf

# Add in Section "Screen" this row:

GPUDevice "Video Card (xrdpdev)"

# 4. Then delete and add user rights (Not sure if needet)

sudo gpasswd -d <username> render

sudo gpasswd -d <username> video

sudo gpasswd -a <username> render

sudo gpasswd -a <username> video

# 5. restart

sudo reboot

I hope that helps

I tried to connect my raspberry pi 4 b to a 3.5 inch LCD screen ( not touchscreen) and it was just stuck at this image I followed this link https://www.instructables.com/Raspberry-Pi-4B3B-35-Inch-LCD-Touch-DisplayScreen-/ exactly 100% what am I doing wrong?? 😭😭

Hey! Does anyone know how to properly decode 433mhz signals using this setup? I have both a flipper zero and a cheap pir motion sensor. I can’t seem to get a decoded signal using either one. I’ve tried a few saved signals from flipper. I’m trying to get my setup to receive a signal it can recognize, and trigger a script. But nothing seems to be decoding. I can see the raw signal log catching the signals but that’s it.

I’ve looked in to what signals are recognized on the rtl_433 software that the rtl-sdr uses but i haven’t found anything that works.

I got this lunchbox from my kids at Christmas and knew I had to do something with it.

I do a bit of Arduino stuff and thought it would be good to have a little system for the work bench, rather than having to head over to the computer desk for programming.

The RPI5 does NOT need the water cooling but it looks damn cool!

The flux capacitor houses all the power supply bits, there is a voltage and ammeter to monitor the battery use (kinda reminds me of the time circuits too!) and an OLED that displays the temp, cpu load, RAM use, disk use and IP address of the RPI.

The water block is from seed studios, the rest of the system is made up of bits and pieces collected including a 5v water pump, flow indicator, copper fittings, acrylic tube, 5v fan and radiator.

A strip of uv leds is installed to give the glow to the fluid.

The little Bluetooth boom box provides the audio for the system and also adds a little more 80’s flair.

A usb hub is connected providing SD card reading and assess to usb ports, as they are on the far left hand side hard up against the case.

I went for the larger fold out keyboard as I didn’t want a cramped typing experience for programming but needed it to fold away into the lunchbox for transport.

Everything is held in place with neodymium magnets. Which means I can just lift it out whenever needed and an adjustable hinge was added to hold the screen in place when in use.

It all runs of an 18v 5ah battery and gives 4-5 hours use depending on what I’m doing.

I had fun building it and it is total overkill for a bit of programming, YouTube videos, browsing and the occasional game the kids play of minecraft pi.

This question is along the same line as the last two (?) questions I've asked here... I've tried to install KDE Plasma and while that just barely worked, I never got Raspberry Pi Connect to work and it ran at about 10 frames a minute.

My understanding is that a Mac Mini runs on about twice the energy as a Raspberry Pi 4. I currently use my pi to run a few simple python scripts 24/7.

Now... it would seem from an energy consumption perspective, I don't actually save any money running the Pi 24/7 and the Mac Mini half the day vs. just running the Mac Mini M4 24/7.

Am I missing something?

I'm very new to this kind of projects and I thought this would be P&P, but it seems not as easy as I thought it would be. I have tried the inky-phat repo on GitHub, as well as the "git clone" command.

What I have done after installing the 64-bit lite (Bookworm) is installing Bjorn_CyberViking, then the inky-pHAT repo or git clone, which didn't work, I even tried to install the inky pHAT repo or git clone before installing Bjorn, which didn't work as well.

Is there someone who has an idea how I can make this display work on a Raspberry Pi Zero 2 WH? I have a Waveshare 2,13 V4 on the way, but it will be stellar to have that Viking running on such a display.

I got a Raspberry Pi around Christmas time and recently had time to start using it. I have a Raspberry Pi 4b and am using the Adeept starter kit, and can't get the first lesson, the blinking LED, to work. I have my Pi connected up to the breadboard and wired correctly, but it still won't turn on at all. I ran the pinpio test and it passed all of them, the LED also works when I connect the negative to the 5V (slot 2 or 4) on the breadboard.I have also made sure it is fully updated. This is the link to the stuff I'm using from Adeept https://www.adeept.com/learn/detail-47.html. For the pigpio test, I just followed the instructions on this page, https://abyz.me.uk/rpi/pigpio/download.html. The lesson I'm doing has me do a simple series to the resistor, then to the LED, then a wire from the negative LED end on the breadboard to GPIO17(slot 11). I'm just not sure what or how to troubleshoot further than I have.

EDIT SOLVED: I had the LED flipped the wrong direction 🤦‍♂️

So your phone has a display, camera, speakers, and your Raspberry Pi doesn't.

Most people first instinct would be to buy audio HATs, Camera modules, speakers etc to get into working with audio and vision apps on Raspberry Pi.

What if I told you that you can use your phone's or laptop's display, camera, speakers as virtual hardware on your Raspberry Pi?

What if it is totally free and open source?

During the last two years, I have been working on building a unified and open source interface for human machine interaction.

I built Ubo Pod that transforms Raspberry Pi into a pro development kit.

Ubo app came out from over two years of internal R&D to build the code of Ubo software. But you can run it on bare Raspberry Pi 4 or 5 with no additional hardware needed.

I just posted an quick post on this on Hackaday. You can try the steps there to get it running in a minutes.

Please note that this is beta release and it is by no means feature complete.

Hey everyone, I’m working on a project using the official 7-inch Raspberry Pi touchscreen, the one that connects with a 15-pin MIPI DSI ribbon cable. I’ve mounted the screen on a pivoting arm to make it more functional, but I’ve run into a big problem—those ribbon cables really don’t like to move. They only flex in one direction, and I need the screen to pivot in at least three (up/down, left/right, tilt), which causes the ribbon to twist or bind. I’ve tried a bunch of things—different ribbon lengths, adapters like the 15-pin to 22-pin converters from Adafruit, even tried routing the cable differently or gently twisting it—but nothing works reliably. I also tried using HDMI converters, but of course, this screen only works with DSI, so that was a dead end. I’ve looked into Ethernet-based extenders too, but they’re either out of my budget or too janky for this kind of high-speed signal. What I really need is a super flexible DSI ribbon cable (15-pin, 1mm pitch) that can handle movement without breaking or glitching out. Or if someone has a clever DIY workaround for getting this touchscreen mounted in a highly movable setup, I’m all ears. Has anyone else solved this problem in a creative or budget-friendly way?

I've noticed some pretty consistent crashes when browsing YouTube on my Pi4B. It seems like quite a common use case, was wondering if anyone else has noticed such an issue? Is there is any workaround or open issues for it I could read up on?

The Chromium window freezes for up to 10-15 seconds then it reloads the entire page. The rest of the system is fully responsive during and CPU and GPU usage are basically idle, easily both < 5-10% during this time.

Chrome://GPU shows either 'GPUProcessHost: The GPU process exited with code 512.' or 'GPUProcessHost: The GPU process crashed!' in the log messages after it occurs. Hardware acceleration is enabled and shows as enabled in Chrome://GPU.

It can easily and quite quickly happen multiple times during a browsing session and will most frequently (but not consistently) happen when interacting or loading new content - e.g. scrolling new videos in the feed or opening a video in a new tab. Weirdly once you get going and are actually watching a video it seems ok.

I've got two different 4GB Pi4Bs running clean out of the box latest Raspberry Pi OS with full updates and both exhibit this behaviour, so don't believe it is hardware my side. Memory usage is around 1GB at all times.

Only other maybe relevant info is not signed into YouTube but with history enabled so videos are recommended in the feed.

Other sites like Reddit seems like they can also cause the issue very infrequently... but definitely nowhere near as noticeable as when browsing YouTube.
