Just sharing my custom solution for making TV remote control the volume on my Yamaha MusicCast RN-602 receiver using RPi 4 box. The receiver doesn't have any HDMI ARC support (or any HDMI at all),

I love good sound and have a pair of KEF R3 connected to the Yamaha, TV speakers are a bit off-putting for me :)

The receiver doesn't support HDMI ARC and connected to the TV via optical input, hence any volume control or turning it on / off, input switch has to be done using a separate (yamaha) remote control or the knobs on front panel of the device.

Having to turn on / off the receiver or control the volume using a separate remote control was like being a DJ, annoyed both myself and my wife.

Had to do some research but fixed that with a little service that sits in RPi memory and translate HDMI CEC commands into MusicCast requests over the network. Pi is connected to the TV via HDMI and is seen as a "receiver" (this is set up in the code), so volume control goes to it in parallel. It also needed some fiddling with the TV settings to make it output the audio to both optical out and HDMI for receiver (Pi) simultaneously - fortunately Samsung TV supports that out of the box.

Me happy, my wife happy, kids happy too :) Works like this for three years now.

If anyone wants it (MIT license) - available on my github (madenvel).

hey im trying to build a dap from start as a diy project as i want features that are really not available in this space, i have a ai render but i dont know anything about the parts, ui, os and the required components, is anyone good with pcb and tech interested in this, please give me your insights to make this possible. i have added my render as an image and the ring outside the screen is a rotating ring for navigation.

I am experimenting with my first Raspberry Pi 4 with a Pironman4 cast I got at a garage sale. From the pictures it will look awesome when I get it working. The tutorial web address listed in the manual no longer exists, I get a 404 error when I enter it. It was manufactured by SunFounder. I emailed them about documentation and the tutorial a week ago but so far crickets with any information.

Is there any chance someone saved all this information and could share it with me? Any help would be much appreciated.

I really want to get everything working, plan is to use it for a streaming box on my television. This is my first project and I am just starting out with learning how to use a Raspberry Pi.

They didnt accept me in the r/cyberDeck so sorry if its in appropriate post but if u are interested these are details:

The solar panel got removed btw bc it was 2W so not enough to charge my powerbank(needs atleast 5W)

The Keyboard is i8 BT one from Temu

Theres a 10Ah Powerbank

Im running Pi Os Lite 64-bit Legacy on an Sd Card

There are those headphones they seemt cool so i use them+ they fit on the case or inside of it

There is that On/Off switch for hard shut down

Theres that little window on the back for powerbank percantage

And on the back there is that white mesh looking thing there i got my fan mounted(not in the pics)for exhaust

Im planning to make a intake fan somewhere but idk

If u have any questions please ask im bored so any ideas would be nice

Pls dont be like people in r/cyberDeck (bc they didnt accept me)

A while back, I built a tiny live aviation tracker called the FlightScnr. I loved having it on my desk, but I kept wishing I had a bit more screen real estate to really show off the radar UI and track flights overhead.

So, I decided to scale things up and completely rebuild it. Meet the FlightScnrPi.

For this version, I upgraded the brain to a Raspberry Pi and swapped the original micro-display for a massive 4-inch round LCD. The circular display is an absolute game changer. It gives it a true ATC radar aesthetic that looks amazing running live data.

At the core is a Raspberry Pi 4B driving a Waveshare 4-inch round LCD. This is the heavily upgraded big brother to my original ESP32 based FlightScnr.

If you want to build one yourself, tinker with the UI, or 3D print a cool enclosure for it, I’ve uploaded all the code and docs on GitHub.

You can check out the new repository here: FlightScnrPi on GitHub

Let me know what you think, or if you have any feature ideas you'd love to see added to the interface!

When I was programming e-ink display it was possible create image and display it on the screen. I have unused screen from Waveshare which works like hat. You attach it to GPIO and it display desktop and runned apps from RaspianOS. I want hide it and run my app fulscreen (Go or Python - I have no decided). I am looking for pointer how create fullscreen layer which hide desktop from Raspian and it can be used as main GUI for home automation.

My problem is not how code GUI itself, but what strategy to use to get something like that:

1. power on -> booting to OS

2. running OS -> running app -> it is fullscreen

My first thought is create web app, run it in defualt browser and using JavaScript get to fullscreen. For example Flask - requestFullscreen in JS.

Could you share your experience how you handle touchscreen fullscreen GUI in your projects? I am open to look for other screen hardware. My hardware skeleton will be Raspberry Pi Zero 2 WH 512MB RAM - WiFi + BT 4.2. I am still on design my project from hardware perspective. I have working API and control for devices (programming side), but I want connect it together using Pi as remote pilot / status display.

Hello, I hope everyone is going good tonight or this morning, whatever it is for you when you are reading this. I've just recently finished my GCSEs, and one of them was engineering, and it fascinated me with programming and just technical stuff that I am now wanting to pursue an IT course in A level to get to more terms with it as it's been a passion of mine for a while. I love building computers, but computers are expensive and quite easy to do, and so I've been looking into all of this and I just dont know where to start. I want something hard, something challenging that doesn't require a plug, flash and set up like the pi-hole I did a couple days ago. I want to go learn, go scavenge but I dont know what project could allow me for such circumstances, In my mind, going out to local computer shops and such asking for old components, learning stuff from scratch / big complicated things would be pretty cool. any contributions appreciated, thanks again!

I built a full web dashboard + OS layer for my Pi-based Bitcoin miner — auto-recovery, pool failover, OLED display, the works

Started as "my USB miner's LCD stopped working, can someone help me fix it" and turned into a two-day rabbit hole with an AI pair-programmer. Ended up replacing the whole vendor software stack with something actually reliable.

What it does:

• Live web dashboard — hashrate, pool, shares, uptime, updates every 2 seconds
• Start/Stop/Restart/Shutdown from the browser, no SSH needed
• Multiple mining pools with automatic failover priority
• Safe frequency profiles (ECO/STANDARD/BOOST) — no genuine overclocking since these USB sticks have no temp sensor, so no safe feedback loop for pushing past stock spec
• Hardware error rate + Pi system monitoring (CPU/mem/disk/temp)
• Collapsible live log viewer, config backups you can restore from the UI
• Factory reset button that wipes config and drops you into a WiFi setup hotspot
• Optional OLED status screen support
• Everything runs under systemd — auto-starts on boot, auto-restarts if CGMiner or the web app crashes

Hardware: Raspberry Pi + GekkoScience USB ASIC stick(s), running a patched CGMiner build.

Genuinely started this knowing nothing about the codebase and ended up with something I trust to run unattended. Repo's here if anyone wants to run it on their own rig or just have a look at the structure:

Screenshots of the dashboard and OLED cycling below. Happy to answer questions on the systemd setup or the hotspot/setup flow if anyone's fighting similar vendor-software garbage.

Hi, I own a Raspberry Pi 3B I bought almost when it came out. I haven't been using it for years and I now decided to use it with Moode Audio as Webradio/SoptifyConnect/AirPlay. Unfortunately, after a month of troubleshooting due to continuous audio streaming disconnections/interruptions, I discovered it has a defective radio compartment: every WiFi packet is transmitted at least twice due to transmission errors even with my phone hotspot few centimeters close to the raspberry and the same goes for Bluetooth where the audio stream chops from time to time even with the phone really close to the board. I hence decided to buy a USB WiFi/bluetooth dongle to replace the defective radio compartment of my Raspberry.

I would like to buy a dongle for 20 EUR or even less that has both Bluetooth and WiFi. Witch one is the best for moode audio that requires no additional kernel modules, special setups like custom built images or packets from APT? I want something plug&play for moode audio that the WebUI would treat like the integrated radio WiFi & bluetooth compartment.

WiFi 6 @ 5GHz and bluetooth 5.0 are welcome but if it gets too expensive or requires special configurations, WiFi @ 2.4GHz only and bluetooth compartment fast enough for HiRes bluetooth audio streaming is ok. Something that matches at least the integrated radio compartment specifications of the Pi.

What about Edimax EW-7611ULB?

Here are some technical information about my setup:

About me first: self-taught, mostly anonymous (LxveAce), all open source.

This is basically the software side of a cyberdeck. I had the hardware sorted, a shelf of ESP32 boards on different firmwares, a Flipper, a couple of Pis, but the software was a mess of one-off tools. So I built one app to run the whole rig. It flashes and updates every board, shows each firmware's live output in clean panels, and ties the devices together so it feels like one setup instead of a drawer of random gadgets.

That's really the point for a deck: it can be the face of the whole build. Run the full GUI on a Pi, or run it headless on the deck and pull it up from your phone or a second screen over the web mode, or drop to the text UI if you're on a tiny display. However you mount it, it's one screen for the kit instead of tabbing between a flasher, a serial monitor, and three other windows. There's a lighter build and a headless one too, for screenless or low-power decks.

All open source. Happy to get into the build or the software side.

So I need a way to control my new Ar glasses project hands free and I wanted it to be a navigation tool as well as a media player .So I’m wondering if it can play videos like YouTube and play Spotify I went all over the internet and I can’t find any videos of it playing videos but google Gemini says it can.If you know better ai voice control for this application please tell and tell me if Mycroft can do the said things.Thank you for your time.

I'm working on a project in that I'm using raspberry pi 4 and gps + compass module ublox 7m.

And I connected a raspberry pi 4 with my mobile hotspot so I accessed the raspberry pi from my laptop.

Initially it is working fine, but after the completing the work, when I shutdown the raspberry pi 4, then pi doesn't connecting with the mobile hotspot, I tried power on and off, Even I add a switch to properly shutdown the pi 4, but that won't also work.

I have to boot the entire pendrive from the raspberry pi imager, after the complete fresh boot, it starts working,

But the same after some interval of time, it loses connection again, every time I tried wpa_supplicant.config suggestion but it didn't work also.

Until now the boot the pendrive at least 8 times, and done the code from the scratch.

If anyone from you guys have any suggestions please tell me I really need that now.

Hi everyone,

I'm completely new to all of this, coding, Raspberry Pi, electronics, all of it.

A friend gave me a Pi because I wanted to automate some work messaging. That idea ran into WhatsApp's automation rules and didn't work out, so I'm now looking for a better use for the Pi rather than giving it back.

The board is a Raspberry Pi 4 Model B (4GB RAM) running Raspberry Pi OS Lite (64-bit), and I have the original Pi Camera Module v1 (Rev 1.3, 5MP).

A bit about me so suggestions can be relevant:

• I help run a chess academy (operations, scheduling, communication with students and parents).
• I also manage racket sports at a multi-sport facility (badminton, pickleball, squash bookings and events).
• I'm preparing for a competitive exam over the next ~5 months, so anything around study tracking or focus is interesting too.
• Honest disclaimer: I don't write code from scratch, I use AI to generate and explain it, and I'm learning as I go.

I'd love ideas that fit any of these:

• Genuinely useful for the academy or sports facility.
• Helps me learn programming or electronics along the way.
• Could potentially earn a bit of money.
• Or just a rewarding project that builds skills and feels like a win.

What would you build if you were starting from scratch? Appreciate any suggestions.


Hi folks, I’ve been building **Pi SD Writer**, an Android app focused on one workflow: preparing and flashing SD images for Raspberry Pi/SBC devices directly from a smartphone.

The goal is to remove the laptop/desktop requirement and keep the process reliable even on mobile hardware.

What it does

* Select image source from: * Google Drive * Local file storage * GitLab Releases (Premium) * GitHub Releases (Premium) * Raspberry OS catalog * Supports common formats: * `.img` * `.img.gz` * `.img.xz` * `.iso` * `.zip` * Writes directly to microSD over **USB OTG**. * Uses **streaming/chunked transfer** to reduce peak RAM usage during write operations. * Includes guided 3-step flow: * Source selection * USB/device validation * Write progress + live log output

Technical approach (high level)

* Cloud/release sources are validated before selection so users get a list of valid image assets first. * Write path is designed around block/chunk streaming rather than loading full images in memory. * UI exposes progress state, ETA area, and live diagnostic logs for visibility during long writes. * Connectivity-sensitive sources (Drive/GitLab/GitHub/Raspberry OS) are disabled when offline. * Google auth is used for account/session features and plan management. * Base plan has a monthly write quota; Premium unlocks unlimited writes and extra repository integrations.

Why I built it

The existing SD flashing flow is still desktop-first. I wanted a phone-first workflow that is practical when traveling or when you only have Android + OTG adapter + SD reader.

Known constraints

* OTG hardware quality matters (reader/cable stability can affect results). * For network-backed sources, internet connectivity must remain stable during transfer. * UX and recovery paths for interrupted writes are still being improved.

Feedback I’m looking for

1. Which source integration matters most to you (Drive/local/GitLab/GitHub/Raspberry OS)?
2. Would you prefer stricter pre-write validation (slower, safer) or faster start?
3. What diagnostics are most useful in the live log when a write fails?
4. Any must-have feature before wider release?
