PI Pico Flight Controller on QuadCopter with Video LiveStream to Phone/PC on same network (WiFi)
My idea was to build a drone that would be running some CNN network on the image from the camera. The first step is to get a drone up and running with RF Controller! Second step to attach a camera and video feed! Third step is to process video input with algorithms and get desired movement response.
So I have been doing some research one of which is your videos and I have seen the basic parts of drones:
1) Brushless Motors x4
2) 4 ESC or a 4in1 ESC
3) PDB
4) FC
5) Reciver
6) Transmiter
This is basic drone setup with no vision. Which is the picture shown below! (1st Picture) I was woundering regarding the FC (Flight Controller) as they are pricey how hard is it to get it up and running and functioning on your own? The Flight Controller consists of Pi Pico and Mpu6050, Qmc5883 Modules. These calculations can run I have seen a similiar project! Could I also use GPS and can the Pico handle its calculations?
The Reciver and Transmiter can be bought although ill build one myself with Arduino.
All other is bought as parts, machined parts not easy to make urself!

cm4 flash issues
first im pretty new to Pi. (have used octoprint/mainsail/kliper)
cm4 with emmc and Wifi, the chip came from a scyncobit hnt miner.
cm4 was working fine just needed a new image.
used
https://www.amazon.com/dp/B0BL37N993?psc=1&ref=ppx_yo2ov_dt_b_product_details
loaded the new image with pi imager, with rpi boot.
on startup act 3s 3l.
pi imager ran erase.
(rpiboot.exe -d msd -v -l)
now rpiboot gives only:

Art Installation - Shape recognition
Hello @everyone,
I'm new to programming, let say it first.
This is my first big project, and it needs to be done for the end of June. So I still have lot of time.
The idea : Have a big cloud at few feets high that react to people dancing under. This will trigger thunder, lighting, and rain. This is for a Burning Man installation (if you know it), so in the middle of a desert.
How : Use the camera placed top down to recognize some shapes or even simple objects (umbrella, cloud, thunder) drawn by people underneath. Activate addressable LEDs, play some sound, and activate a water pump with a 4 way relay
What I have :
Rasp 3b
Raspcam IR
Raspberry DAC Volumio
WS2811 LED
12V water pump
4 Way delay, 12V
So at this point, I'm not sure how to handle the recognition part. I was thinking of openCV and some shapes recognition, but having people, shadows and so this will probably not work.
So maybe training some GAN, but I can't find enough picture to create a proper dataset.
Maybe there is a better solution that I'm not aware.
If anyone has an idea on how to do ?
Thank you

Use Pi as Wireless Access Point AND access that pi like a server
Hi, I'm looking for a point in the right direction. I've followed a bunch of the guides to create a pi access point, but I need some direction on obtaining an IP for the pi that is serving the hotspot. The pi by default seems to create an AP that is subnetted separate from the pi itself.
In my ideal world, I would have zero ethernet. Zero internet. Just a pi with Apache and the wifi hotspot allowing others to connect to that apache server.

Could anyone help me on this?
Potentiometer:
Modify your build to add a potentiometer to each of the color legs of the RGB LED.
Program to light the color only when the photoresistor senses no light.

Network at Boot - Does it ever time out?
If I set my Pi to wait for Network at Boot, but for some reason my network goes out, will the Pi never boot at all, or will it timeout and just boot normally after awhile?
I have it set to display the IP address on the terminal after boot, but sometimes it's blank after booting, but when I turn on Network at Boot, it works every time. I just don't want it to be completely locked out if the network goes down.
Thanks!

Looking for a Simple Basic Project for Beginner to learn
I have a raspberry pi 4 here. I have a breadboard, some LEDs, some resistors, a button
I am looking for a simple beginner project, talk to me like I'm a 5 year old who can read with good documentation so that I can learn working with Raspberry Pi, creating something on a bread board, pin assignment and basic Python -> to get hardware to do something.
I know some Python - I can also look up things when I get a good base down
A little about breadboard LEDs but I'm not great - I was trying to get this stupid LED to light up and I did for a bit then it died.
I just would like a step by step project that I can see a positive result and then branch out from there.
Any suggestions would be appreciated.

can someone help me with my project 🙁 theses are the instruction.
Insert the Arduino Uno board on the breadboard, with its pins aligned with the breadboard's power rails.
Connect the cathode (short leg) of the first LED to the ground rail of the breadboard using a 220 ohm resistor.
Connect the anode (long leg) of the first LED to pin 13 of the Arduino Uno board using a jumper wire.
Connect the cathode (short leg) of the second LED to the ground rail of the breadboard using a 220 ohm resistor.
Connect the anode (long leg) of the second LED to pin 12 of the Arduino Uno board using a jumper wire.
Connect one end of the push button to pin 2 of the Arduino Uno board, and the other end to the ground rail of the breadboard using a jumper wire.
Connect the photoresistor to the breadboard, with one leg connected to the power rail of the breadboard and the other leg connected to the ground rail of the breadboard.
Connect the middle pin of the photoresistor to pin A0 of the Arduino Uno board using a jumper wire.
Connect another 220 ohm resistor from pin 2 of the Arduino Uno board to the power rail of the breadboard.

multiple servers on a single Pi4
Hey I have a spare RPI4 8GB.
I'm currently running octoprint off a 3B using a few GPIOs for Octolight (going to a relay) and I'm wanting to setup a PiHole. I know PiHole is not very intensive.
Would it be feasible to just run Debian or something else and set up the 2 sperate servers on the same 8gb pi?
What is the best way to approach it?
Should I just leave the separate servers as individual pi's?
I do power down the octoprint server if the printer errors while im away is this a bad idea if I was running pihole on the same pi?
Is there a way to trigger the server to shut down/restart from my wifi switch or from a tuya server?
Thanks in advance

Bootload Errors
I am trying to figure out what is causing this issue. I have 16 RPi4's installed and 2 devices boot to this error "occasionally". When it happens, sometimes I can reboot the Pi and it boots fine. This particular image, I have not been able to reboot it into a functioning OS. Another device, it works sometimes and doesn't work other times after rebooting. I originally had this issue when I added another FAT32 partition to the mix. Removing the partition fixed the issue (although, I did notice the error a couple times beyond this).

Audio not working
So right now if i plug my headphones to jack on rpi3 and manualy play music, the sounds works great.
But if instead play music from python program(using pygame) the sound not only is transmited via HDMI to speakers connected to screen, the sound quality is REALLy terrible
How can i fix it so the audio is always transmited via jack? And also what about the sound quality?

raspberry pi as music player

FFMPEG Optimize Encoding for Chrome Video playback on RPI
I am in search of someone who can help me optimize some video's using ffmpeg. The videos will be streamed internally on a network to ~ 50 raspberry pi's that will play the video on chrome using html <video> tag. If anyone knows of a discord or subreddit or any direction to point me. It would be greatly appreciated.
I am currently just choosing random encodings and adjusting sliders hoping for the best.
