Camera memory repeated problem
So when I run a stream function (seen below), my camera starts a stream and all is good. BUT after running it a few times a day and after a couple of days it stops working and I get this error code:
mmal: mmal_vc_component_create: failed to create component 'vc.ril.camera' (1:ENOMEM) mmal: mmal_component_create_core: could not create component 'vc.ril.camera' (1) Traceback (most recent call last): File "/usr/lib/python3/dist-packages/picamera/camera.py", line 456, in _init_camera self._camera = mo.MMALCamera() File "/usr/lib/python3/dist-packages/picamera/mmalobj.py", line 2279, in init super(MMALCamera, self).init() File "/usr/lib/python3/dist-packages/picamera/mmalobj.py", line 631, in init mmal_check( File "/usr/lib/python3/dist-packages/picamera/exc.py", line 184, in mmal_check raise PiCameraMMALError(status, prefix) picamera.exc.PiCameraMMALError: Failed to create MMAL component b'vc.ril.camera': Out of memory
After allocating more memory to the GPU the script runs as espected again BUT after a few days it happens again! Why is this and how do i fix it? Rebooting does nothing.
def main():
StreamProps = ps.StreamProps
StreamProps.set_Page(StreamProps,HTML)
address = (raspberry_ip, port)
StreamProps.set_Mode(StreamProps,'picamera')
with picamera.PiCamera(resolution='640x480', framerate=30) as camera:
output = ps.StreamOut()
StreamProps.set_Output(StreamProps,output)
camera.rotation = 0
camera.start_recording(output, format='mjpeg')
try:
server = ps.Streamer(address, StreamProps)
print('Server started at','http://'+address[0]+':'+str(address[1]))
server.serve_forever()
finally:
camera.stop_recording()

Hello,
I am recently trying to power my RPI 4 with a buck converter, going from 24v to 5.1v.
When i plug the power supply from RPI there is no sound and every LEDs are flashing correctly.
When i use my USB C cable from my buck converter to the PI there is a little sizzle noise comming from the USB C port. All LEDs are also flashing correctly

HC-05
Hi, I'm having an issue with communication between two HC-05 modules. One module is set as the master to send data from a Raspberry Pi Pico, to which a joystick is connected. The data is sent via Bluetooth and received by the second HC-05 module set as a slave, connected to a Raspberry Pi 4. After a few seconds, I encounter this error. What could it be? How can I resolve it?video

How to hide the cursor (unclutter doesn't work)
Hey 👋 i'm a beginner and i am making a simple kiosk dashboard and i want to hide or disable the mouse cursor.
On Rasbian 64bit (i downloaded via the imager very recently) i open chrome on startup in kiosk mode with my website.
But the mouse is still visible and it also is hovering some elements on the page.
A lot of online resources like [this one](<https://forums.raspberrypi.com/viewtopic.php?t=234879>) use package called unclutter.
But if i open terminal and run unclutter -idle 0 and leave the mouse idling, it never gets hidden. I'm mainly asking here to check if unclutter does work as expected or if i just use it incorrectly.
I read somewhere that this could have stopped working due to newer version of the graphical interface. And also i haven't found any posts from 2023+ regarding usage of the unclutter package in connection with RPI and hiding the cursor..
Any ideas what should i try next?
I also added somewhere "-nocursor" parram, i presume that was a cfg for the graphical interface. But that didn't disable the mouse, nor did disconnecting the mouse from the USB.
I'm really unsure what to search for since all results are around 2019 using unclutter.
Any directions, hints and advice is welcomed :)

raspberry pi 5 speaker problem
Hello,
I'm using Raspberry Pi 5 8gb version for a project. For a text to speech app, I need to use speakers to listen the assistant's voice but there is a problem. I plugged the speakers' jack into a sound card and I plugged USB port into my laptop for power supply and I got a sizzling sound from the speakers. They're working when I used on my laptop but they're not on Raspberry. How can I solve this problem?

Wifi not working
I flashed a fresh install RPI OS bookworm 64 bit lite onto a SD card for a 3B+ and the wifi doesn't work. Pretty certain my SSID and password are correct. The pi is in a cluster case with another pi (running 64 bit desktop) which is connected via wifi working fine. Ethernet works but would rather use WiFi for now.
Board: 3B+
OS: RPI OS lite Bookworm 64-bit headless

DSI display
Hi everyone! I am using a CM4 module. I wanted to use a 7 inch DSI display which uses the ILI9881 IC. I got the inspiration to use this from the cutiepi tablet project. I designed a PCB and added dtoverlay = cutiepi-panel to my config.txt. I get output to my display but it blurry and the entire row lights up. Any help would be appreciated! Thanks a lot!

RPI 4B power supply issue
Hello, I recently ran into trouble with my RPI 4B. It worked fine for a while, I took it out of the case for the time being as I was waiting for a better case to arrive. My hand bumped into the pi while it was running and it looked like it was going to reboot. After waiting a while and restarting it manually a few times, the pi does not seem to boot. Both the red LED and the green ACT LED stay on constantly once power is connected. I tried starting with nothing connected but the power cable, however the problem did not seem to go away. I thought maybe the bootloader was corrupt but that also does not seem like the issue. Any advice on what I can do to troubleshoot this pi?

Booting from USB with USB-hub not working
When I try booting from an SSD connected to a USB hub raspberry pi os won't boot, even though it says
USB2 root HUB port 1 initand
USB2[1] 400202e1 connected. When plugging the SSD directly into the pi it works but takes extremely long as I think its not getting enough power, so I need it plugged into the powered USB hub. It did boot through the hub a few times before but now it doesn't idk why

Pi 5 fan activation bracket [SOLVED]
How can I lower the pi 5 active cooler fans activation bracket? Not sure if it's British temperature but my pi idles at about 45°C and only just about reaches the first bracket at full throttle. To get that little bit more out of my pi and prevent the die from breaking from too much thermal changes how can I lower this temp and/or keep the fan on constantly. For whatever reason the option isn't in sudo raspi-config like temp control is for the pi 4.

Half-Life PortMaster ArkOS error?
!!!! NOTE: This isn't exactly a Raspberry Pi issue, but the systems are incredibly similar and this problem mostly involves a form of (i believe) Linux, which I know this community is very knowledgeable about. This is the last place I wanted to ask this, but I already posted it everywhere that is dedicated to this stuff and got ZERO responses. Thank you.
I'm trying to play Half-Life through PortMaster on ArkOS, but the game won't start. When I run it the first time on startup, it shows a terminal with some lines about copying config files for HL, OF, and BS. But then it boots back to the menu.
Checking the log.txt file reveals this error: "taskset: failed to execute ./xash3d: No such file or directory".
Extra info: I'm using the 2nd slot SD card. The system is an Anbernic RG353PS. The PortMaster is updated to the latest version, and Half-Life worked even less before the update (didn't even show the command prompt).
The file structure of the port (how i have it set up) goes: "ports" contains "Half-Life", which contains "valve" (half life 1 files), "gearbox" (opposing force files), and "bshift" (blue shift files), as well as the default files that came with the port. Note that "xash3d" IS, infact, among these files. I also copied it to all 3 game folders, and the "binaries" folder, which has 3 subdirectories name after the 3 games that, for whatever reason, I cannot open on my PC. The error says that they are corrupt, but I have not changed them myself.

Pi-Hole troubles
I followed the Network Chuck tutorial if anyone is familiar with it. I ssh'd to the pi and ran the commands to install AdGuard Home last night. Went to config the DNS server on my router and it doesn't give you the option. This morning, I was able to ping the Pi but couldn't get to the AdGuard Gui through 192.168.0.X. When I ran the ls command, nothing was output. When I used the command from the Chuck video to download it - it told me it was already downloaded.. Umm??? So I reinstalled with -r and was able to acceess the AdGuard Gui again. Manually set the DNS server on my Windows HP, ran WireShark and the Pi-Hole STILL won't get the DNS queries, all of those were done using IPv6. I can't even begin to understand where I'm going wrong

I have some files that I saved and needed for my ongoing project on my Pi and the thing in the title happened. I really don't want to start anything from scratch and I can't seem to get the files back or anything. I'm not sure what the problem is since I just started all this. I am really desperate for help with this.

Pico as a USB hub *and* UART
I am designing a digital mode interface for my ham radio. The details are not too important - what I need from the Pico is to act as a UART serial device, preferably with an RTS/CTS interface too, but an added bonus would be if it could act as a USB hub at the same time, as I am also using a sound card and I would love to have everything on one cable. Is that even remotely possible?
