Auto starting NPM program after reboot
Hey all,
Forgive me am still fairly new to coding/software, recently got my hands on my Pi 5 which I'm loving, following the guide found here - https://github.com/vexorian/dizquetv/wiki/Raspberry-guide I've set up and have dizquetv working on my pi, the only issue is when the device powers off I need to SSH in, start a screen session and restart it with an NPM Start command. Is there a way to automate this, and could someone help me out with some idiot-proof steps?
Thanks in advance 🙂

VNC & HDMI are loosing connection after Pi is running for some time
Hello I am using the PI-4. He is connected through a LAN cable. I am running a python scirpt on it and therefore want him to be always turned on.
When I turn the Pi on, while a HDMI cable is plugged in, he connects normally to my monitor. I go to the settings and turn VNC on and try to connect to the Pi through the RealVNC app. It works. I start the python script and let it run.
I change the signal from the monitor to my PC‘s display port (the HDMI is still plugged in) and use it. I turn the montior off and check back on the Pi at the next day.
I notice that I only get a grey screen as soon as I change the signal from the monitor back to HDMI. I try to connect to the Pi through VNC (what worked the day before) but it doesn‘t work. I just get the error: „The port on which the computer is listening for a connection could not be contacted.“. I can‘t turn the Pi properly of, so is unplug him from the power cable wait shortly and plug him in again.
The Pi boots and connects again to my monitor (the monitor is turned on while I do this). It works again. I go to the settings and look for VNC. It is turned off even though I didn‘t turned it off. Wheb I turn it back on and try to connect to the Pi, it works again.
This repeats every day. I do not know after which time it happens but it is often at the same day.

Monitor turning black after following LCD integration instructions
I followed this instruction to setup my 3.5 LCD screen: https://www.instructables.com/Raspberry-Pi-4B3B-35-Inch-LCD-Touch-DisplayScreen-/
Then suddenly my monitor turns black screen and my LCD only shows white screen. I can't use my RPI since it has black and white screens that's why I can only use its memory card to fix it. What should I do, I already tried editing its config.txt but nothing works. Here is the content of its config.txt:

Raspberry Pi 4 + TP Link WN722N + Kismet Wireless Issue
Hi All,
Hoping someone might be able to shed some light on the issue I'm currently experiencing. Here are the system details:
Device: Raspberry Pi 4 Model B 4GB
OS: Debian Bullseye 64-bit Raspberry Pi OS
Kernel version: 5.15.84-v8+
Wifi Adaptor: TP Link WN722N Version 2.
Driver: https://github.com/aircrack-ng/rtl8188eus compiled from source.
Kismet Wireless compiled from source at https://github.com/kismetwireless/kismet (I've also tried the Bullseye and Buster packages as well with the same result)
I'm successfully putting the wifi adaptor into monitor mode, however when I launch Kismet I get this error:
ERROR: Data source 'wlan1' failed to launch: Command did not complete
Then, my networking services appear to stop working. I'm not sure what the issue is here because no networking related commands work, or return an error message. All commands such as 'ifconfig' 'iwconfig' 'sudo systemctl restart networking' all just hang the console, no error, the console just stops responding. Even the reboot command won't work.
Some further notes:
- The kismet web server is still running and accessible from a remote machine.
- The hci adaptor (bluetooth) keeps working fine.
- Running kismet with no wifi adapter results in no issues with networking commands
- Running kismet with another wifi card, the Alfa Networks AWUS036ACM with the Aircrack driver works fine: no issues.
If you're able to help with fixing the entire issue, great! But if someone is even able to tell me exactly what's breaking then that would help me dig into this further.
The next thing I need to test is whether another program is able to use the adaptor in monitor mode successfully, I had a poke around and found a few options but was unable to install them easily due to incompatibility with Raspi OS / missing dependencies etc, can anyone suggest another application that will use the monitor function on the adaptor that I can use to test whether this is a Kismet or drivers issue?
Cheers!

Enviromental data gathering from using wheelchair and Raspberry Pi 5.
Hello. I've recently embarked on a project using the Raspberry Pi 5 to gather environmental data while on the move using my wheelchair. Goal for collecting data is to measure levels of comfort while moving around city. My aim is to capture accurate and relevant data without investing in resources that won't serve my purpose. Although I'm relatively new to this field, I've done some preliminary research. However, I'm seeking your advice to further refine my approach. Could you recommend the types of sensors best suited for mobile environmental data collection with a Raspberry Pi 5? Additionally, are there any particular learning resources you'd suggest that could help me avoid common pitfalls and unnecessary expenses? I'm eager to learn and make the most out of this experience without investing in unnecessary or ineffective tools.
Thank you for your time and help. Have a nice day.

New WiFi connection
I have a problem with WiFi connection. I am using my RPi 4 to controll my 2 3d printers. I did have everything set up. Now I came back to my home country, brought my printer and RPi4 and I am unable to set up WiFi connection, so I would be able to connect 3d printer and continue doing my projects. I have already tried wpa_supplicant and with ethernet cable but neither of those methods worked. Does anyone have some advice?

Pi3b dead?
Hi all thanks in advance for looking at this post and any help you can provide!
I have an RPI3b that I've been using as a pihole- booting off an usb drive. I noticed yesterday the pihole was down so I powered off the pi and examined the flash drive it reported that it was in read only mode (there is no hardware switch on this drive) so given past experiences I've come to the conclusion since its not a software lock the flash must be erroring and the drive's controller decided the lock out any writes to preserve the data on the drive.
So I thought if I got another new usb drive and flashed it with the official rasberry pi imager I could start again. unfortunately after imaging the new drive the pi will not boot into raspbian it will just sit at blinking cursor on a black screen. I already checked the 3v3 power pin on the gpio and its still reads ~3.3v.
I'm a bit mystified as how to proceed any help would be appreciated!

Need help with PIO for SPI ROM chip reads
Background -- I recently discovered https://github.com/stacksmashing/pico-serprog and since I have a ton of picos and no rom programmers I thought I'd give it ago, except flashrom doesn't detect it as a programmer. Then I discovered the fork https://codeberg.org/libreboot/pico-serprog except that it doesn't implement all commands. So today I forked it: https://github.com/opensensor/pico-serprog and implemented remaining commands.
I think started refactoring the primary rom read command S_CMD_O_SPIOP -- seems to be the problem is related to flashrom reading the entire 16 MB rom I can read from the chip as long as I read a subset that can fit into pico memory and send it one go -- as soon as I chunk the payload the communications with flashrom break.
I've started trying to implement pio spi in a branch, but I am kind of confused. It compiles, but no data is received for the large chunks, meaning the new pio code I added isn't quite right: https://github.com/opensensor/pico-serprog/pull/1/files

Raspberry Pi 3 Camera module not working anymore on bullseye (used to work on buster)

DHT11 on Rust: Timeout Error
I've been trying to use a DHT11 temperature sensor with rppal. My code is the following:
rust
fn main() {
let mut pin = Gpio::new().unwrap().get(18).unwrap().into_io(Mode::Output);
let mut led = Gpio::new().unwrap().get(17).unwrap().into_output();
let mut sensor = Dht11::new(pin);
for _ in 0..10 {
led.set_high();
let measurement = sensor.perform_measurement(&mut Delay::new());
println!("{:?}", measurement);
led.set_low();
sleep(Duration::from_secs(1));
}
}
but measurement keeps being set to Err(Timeout). I have tried using different IO modes and using different libraries too. This crate is dht11, but I have also tried dht-sensor and simple-dht11, to no avail. I also haven't managed to get a measurement with a different language, Python kept crashing in the venv because it couldn't detect the environment.
I connected the VCC to the 3.3V supply, the ground to GND and the data line to GPIO 18. I'm pretty confident it's correctly connected cause I have an LED on my DHT11 that lights up, but I cannot make any measurements whatsoever.

not booting; flashing error code
i bought a "raspberry pi model b+ v1.2" from ebay, and on attempting to boot it seems to be flashing an error code that i haven't been able to identify by googling. i've attached a video; it looks like three short flashes, one long flash, two short dim flashes, and one long flash. even if that's just a three-short-one-long that's consistently repeating poorly for some reason, that combination didn't seem to be listed. does anyone know what this means?

Is it possible to make Raspberry Pi 5 portable?
So, I have a Raspberry 5 8gb RAM I am getting in 2 days for Christmas. I was wondering something.(This is a question for people who already own the product by the way.) Is there some way so far that we can make the Raspberry Pi 5 portable? Has anyone done it so far? Is anyone planning on doing it? If so what would I need to buy, gather, or pre-order? Is it even possible? If it’s possible what would be the minimum mAh I would need in a Lithium Ion Battery)

Pi 3 B+ : 100Mbps instead of 1Gbps
Hi,
I'm new to Raspberry and just got a second hand 3B+.
I checked Raspberry Pi website, and 3B+ should come with a Gigabit Ethernet Adapter (although it's locked to 300Mbps because is going through USB).
On my Pi3B+, the adapter is shown as a Fast Ethernet Adapter, thus allowing only 100Mbps.
I tried this on Debian12, Raspbian Bullseye, Ubuntu 23.10, and have the same thing.
Also, on the switch, it shows 1Gbps connectivity ...
Any idea ?

Pi 5 with sound
Hi, so I'm planning to build a cyberdeck with a Pi 5, and I'm planning to use laptop speakers from a broken laptop I have, and realised I would need an audio amp. I was wondering which of these would be a better pick:
The one with a blue heatsink is a TPA3110 with 8-26V DC, 30W+30W 2.0 amp XH-A232. The red PCB one is a DollaTek 10W+10W 2 Channel 12V DC module. Since the Pi 5 doesn't have an audio jack anymore, I would need to use a USB adaptor to get the audio cable or use GPIO pins. I don't plan to have access to the rotating volume control so I feel like the space on it is gonna be wasted.
I'm planning to power the build off a power bank. I know 30W is going to be better for sound but I'm also conscious of power spend. Not to mention that looking at power banks they seem to be capped below 30W so I'm not sure if getting 30W capability would be even worth it.
Here's two power banks I've been looking at:
Lower wattage, less outputs, less capability but name brand - https://www.amazon.co.uk/Anker-Portable-PowerCore-High-Speed-Charging/dp/B0BYP4Y1N8/
More wattage more capacity more outputs but haven't heard of the brand before - https://www.amazon.co.uk/VEGER-30000mAh-Charging-Portable-Compatible/dp/B0C4DWD4XY/
To be specific the laptop speakers I'm utilising are QT-7326AW-1-W and these are the links to the boards:
Dollatek - https://www.amazon.co.uk/DollaTek-Electronic-Assembled-Amplifier-Portable/dp/B07DJ4NJXR/

RPI 3 B+ Not working. Only red light.
I powered my RPI 3 B+ with a Fast Wall Charger, Model: Q5003-US, Input: AC 100-240V.50/50Hz.0.5A Max, Output: DC 3.6-6V=3A, 6-9V=2A, 9-12V=1.5A
I did some research and the RPI only needs 5V,2.5A... So, I think I fried it. But if that was the case, then why is the red light still working?
I re-flashed the micro-sd, nothing. I used another micro-sd, nothing. I went back the the 5V,2A head and nothing works.
