Use Pi3 to power electronics from a Greeting Card
I have the guts from a greeting card that was originally powered by two CR2032 cells. After some investigation it appears each cell powers the speaker and motor separately, so they only need 3v each. I tested this by removing both cells, then activating each feature one by one.
I'm curious if I can use the 3.3v on the Pi3 to power one or both of those features through python. I'd be adding a button for control to turn it off and on. Realistically I think it would be easier to desolder the motor leads and wire to the Pi directly, but the music portion has a chip to play a specific tune, as well as an external speaker. If it is indeed possible to power this from the Pi, how should I connect it up?
2 white wires go to the speaker
Red/Black to got the motor
The switch is in the corner and is constantly on unless a piece of paper (tab from the card) breaks the connection.

Digital signage with non local access & preferably auto update via a file manager/email/ Gdrive
Hey, I have been tasked with sorting a digital sign for sponsors. Having used Pi's several times, I know you can do this with them, however I have a few caveats.
Use case: Digital Signage
Use load: 4 images maximum or a mp4 of said images with controlled transitions.
Set up: The pi will be permanently to a TV/ digital projector to loop the images/video.
Access: I want this all to be done, preferably, from the comfort of my own home & for free/ no subscription or one off payments to a software. I'd love to have it so that I can upload to a file manager online ie google drive and the pi just reboot and pull the images each time it detects a change in said file system. Or if I email it across the the pi, each email same again. Reboot, pull the new files.
Personal Thoughts:: I've been googling around for two daysIsh and found, but I don't think that can be access off site. Also saw Slidesho for Android, which could work if I loaded Android onto a Pi.
Any thoughts/ help would be warmly welcome. Thanks

Help Article I wrote for Noobs
I wrote an article for the Noobs starting with the Raspberry Pi 5 because I felt like when I first started, there was like zero documentation for certain apps not working. So if I can solve them I can provide the solutions in an article for noobs while also adding personality unlike most help articles and also explaining stuff to the reader so they understand why certain things are done. https://docs.google.com/document/d/1ZVjokHRHGz0HpAggySH4Y4LdddpFmQfnIv0Yo1UvjlM/edit

Rasp Pi 3b as Wirless USB Hub
Hello I recently followed this tutorial to turn a Raspberry Pi 0 into a wireless USB device that I used to send .STL files to my 3d printer wirelessly.
https://www.reddit.com/r/ElegooMars/comments/jxhyi3/using_a_pi_zero_w_as_a_smart_usb_flash_drive_for/
It worked for the Pi 0 but then suddenly I kept getting error messages on the Printer due to some sort of failed communication.
I then decided to try to do it with a Pi 3b. I was able to successfully create the wireless folder that I can put files into remotely but when I plug the Pi into any device via the USB port nothing is coming up. Is their something I need to do different with the Pi 3b versus the 0 in the instructions?

Raspberry Pi4 drops WLAN connection when downloads are running.
My raspi4 drops its WLAN connection when I use my external ALFA USB adapter for downloads.
I use the original power supply and an USB alfa adapter with raspap as a wireless repeater.
My pi is overclocked. Is this a power issue? How can I fix it? I will disable the overclock right now and try again. Is there any other solution?
Thank you in advance.

How to Allocate RAM to the GPU on the Raspberry Pi 5? (SOLVED)
The title basically sums up my question, but Iām just wondering how to do it. As far as I can tell there is no obvious way to do it. With past Raspberry Piās you could either edit the config.txt file and change gpu_mem or go to the Raspi-Config screen and fichan free it there. There doesnāt seem to be either of those options on Raspberry Pi OS Bookworm. Is this because of the OS, which canāt be changed to previous OSās, or is it because of the Raspberry Pi 5? This is just super confusing!

pico w/ Lipo shim power issues - no power at vbus pin
Hi all. Iāve added a lipo shin to my pico but Iām having power problems with it, basically it wonāt power the pico as it should, details are below:
The power out of the lipo connector is good (at source)
Voltage at the 3v3en pin is good, this goes on and off with the button on the front of the shim.
If I bridge power from the +ive on the back of the plug to the VBUS pin we get power and everything works as it should.
However if I bridge from the 3v3en pin (same voltage) then the pico still wonāt power on
If I donāt bridge anything then thereās still power to the 3v3en pin but nothing to the vbus pin
Iāve checked all soldered joints and I canāt see any issues. Does anyone have any ideas which pins I should check in particular or anything further I could do to trouble shoot?

my raspberry pi5 is not compatible to the touch screen I bought.
I got a CX070PI-A IPS 7-inch screen and a Rpi 5. The screen itself works but not the touch screen. However, when I connect the touch screen port from my screen to my normal pc, then it does work so its not the screen but the software of the Rpi. I checked Github and saw a few issues in the past with update 5622, that I installed but no change. I switched back from wayland to X11 but that also did not work and I disabled the entire KMS drivers that also didnt work. ANy tips?

Voltage Divider
Hey Folks,
trying to copy parts of the kinowheels.com project and attach it to a pico instead of an Arduino mega.
So far i replicated just one of the voltage divider and attached only one of the outs of the encoder to my breadboard. Yet I did not added the pico as i measured ~5V (encoder HIGH) on the tap where it should be connected.
Is this due to not having a load (no pico, just volt meter) attached?
When i add another 20kOhms between tap & ground i get desirable 2.5V, but i don't know if i'm doing it right.
Appreciate any help!

Need help booting from USB
Hi,
I recently bought a Pi4 to use as server for Home Assistant. I also bought a USB to SATA-connector to use a old(ish) SSD as boot device. However, I am having issues booting from the USB.
From Googling I found that most people said you needed the official power adapter, which I bought and just got. Besides this, I've flashed a SD-card to get USB boot into the Pi. It works perfectly - the green light flashes rapidly. After this, I disconnect the power to the Pi, I insert the USB with the SSD, and give the Pi power. The red light is constantly on, with the green light flashing fast once, followed by keeping the light on for about 10 seconds. After that the green light turns off, and repeats after about 10 seconds.
Any help is appriciated!

RaspAP not finding clients anymore after raspbian reinstallation but working in terminal.
Hi.
As mentioned in the title it did work but I messed up my raspbian installation and had to redo it. Now it won't find any clients I could associate with anymore.
It doesn't show up clients I can connect with my secondary usb plugged in alfa adapter "wlan1" on the web config page. Scanning in terminal is working fine
If I scan for wifis in terminal my wlan1 is working and showing it correctly.
What am I missing?
Cheers! Max

Weird display (framebuffer?) issue.
I've got a 480x800 display in HDMI-1, and a 1920x1080 in HDMI-2. I normally keep HDMI-1 in an orientation where I have to set its rotation to "left" and it then becomes 800x480. But whether or not I rotate it, HDMI-2 shows the contents of HDMI-1 on the right side of the screen, but with the top line of pixels missing. I've tried numerous adjustments in arandr and in /boot/config.txt to no avail. Also of note is that anything I click on on the right screen, the actual click happens about 2 inches to the left of wherever the arrow is. If I move the arrow onto HDMI-1, it doesn't show up in the area of HDMI-2 where HDMI-1's screen is showing, but the effects of me clicking do.
But where it gets really weird is that if I set the rotation of HDMI-2 to inverted, it works perfectly fine, other than it's annoying having my monitor upside down.

SERVO2040 (New User)
Hello,
Iāve never used a raspberry pi before and I have a SERVO2040 and Iām not sure if itās working right. What happens is the onboard leds are rgb but only flash red. Also Iām using Mu Editor and circuit python. I have no idea what Iām doing but Iām just following the circuit python welcome guide. Also the leds turn like whitish when I press serial and any key in Mu Editor.
