Raspberry pi plane problem

I want to make a rc plane with the ability to be controlled by my laptop with a pi board as the controller for the rc plane. (The reason im doing this is so I can make my own unmanned flight code and other novelties) The main problem with this concept im having is that I don't know how id connect to the plane over a long distance to my laptop. I was thinking maybe via sim card but paying for the bandwidth for video and only being able to fly where there is cell service isnt ideal. The only other thing I can think of is via radio but i have no idea how to even start that. ANY ideas?

(For those worrying about the FAA)

Ive done a very similar project before and my local ordinances and after having talked to the FAA there was no issues so I see no problems with this project. In addition this is all done at a very low altitude on private property.

MPRLS pressure sensor problems

I just bought an MPRLS ported pressure sensor and am running it off a Raspberry Pi 4b. I have the ground, Vin, SCL, and SDA properly connected from the sensor onto the Pi using 4.7 ohm resistors. The problem is when I run my code the value being recorded does not change.

Is there something wrong with my code or my wiring or something else?

My code:

import smbus

import time

bus = smbus.SMBus(1)

SENSOR_ADDRESS = 0x18

CMD_PRESSURE = 0xF0

def read_pressure():

bus.write_byte(SENSOR_ADDRESS, CMD_PRESSURE)

time.sleep(0.01)

data = bus.read_i2c_block_data(SENSOR_ADDRESS, 0x00, 3)

pressure_raw = ((data[0] & 0x3F) << 8) | data[1]

pressure = (pressure_raw / 1638.0) * 60.0

return pressure

if __name__ == "__main__":

try:

while True:

pressure = read_pressure()

print("Pressure: {:.2f} hPa".format(pressure))

time.sleep(1)

except KeyboardInterrupt:

pass

Which HDD Format to Use??

I have a raspberry pi 4 running raspbian lite 64-bit. I am using Open Media Vault (OMV) to wirelessly manage my pi as a NAS and also running Plex to access the movies/shows otherwise. I also use a Mac to manage files on the pi with SAMBA through OMV.

I got a new HDD and am trying to figure out what format to use for my pi for files given it's current services. It currently has a SSD with HFS and works fine *shrugs shoulders*, just didn't know if there was a better format to use. I don't care about speed really, just it being convent and reliable.

I've heard exFAT and EXT4 when looking around, I just don't know enough to really understand the idea of what makes which the best option other than some trivial comments here and there.

Thank you!

Built a Mini KVM for Headless Pi - Hack or Junk?

Built a Mini KVM for Headless Pi - Hack or Junk?

Alright folks, I've gone full mad scientist and have been crafting this mini KVM for a couple of weeks with my buddies, so that I can boss around headless Pi directly from my own laptop, especially when I’m just trying to set up ssh/vnc, and the like, on a brand new image, or rescue a Pi from network limbo.

Sure, who needs that? I mean, accessing / setting up a Pi is something folks here can do with eyes closed, but… when there's no network, no big, fat-ass monitor, and no keyboard and mouse around... See my point? Well, I got annoyed about it. There's gotta be a better way, so here's my attempt...

It's still a work in progress. This version is much neater and less like Frankenstein's monster than its first version on a circuit breadboard with all kinds of wiring, and the second version that was wrapped up entirely with masking tape, which we called the mummy…(what a pity, I forgot to keep these photos, which would surely have made you laugh out loud.)

So, your turn, tell me, is this a help or just another piece of tech junk I’m wasting my time on?

I set up a raspberry pi as a data server. Can I also share files between my pi and a computer via ethernet?

My goal is to have a data server for my whole home, but also have a "sterile" computer (which doesn't touch the internet) have access to the same files. Is it possible to have the pi on a wireless internet network but also a wired network with my computer? If so, could someone provide guidance on how to accomplish this?

I am very much a beginner with the pi and Linux scares the crap out of me, so please ELI5

Using Bluetooth to Connect to RPi WiFi

Does anyone know how products like the Aura Feame use Bluetooth to connect a device to WiFi through an app? I linked to the setup guide so you can see what I mean.

It seems like this is a great way to use RPis in products without the need for users to hook it up to a monitor and connect to wifi.

Are there any other methods for using a raspberry pi in a product and simplifying the process for a user to connect it to their wifi network?

Thank you!

Is "Bluetooth mouse -> pico w -> pc" possible??

I searched all over the net but nobody has tried this senario.

I want to connect my bluetooth mouse to pico w (via bluetooth) and then use the usb port to connect the pico to pc as a wired mouse.

Aim - I want pico to modify the mosue input and then forward it.

I want to know if this is possible with a raspberry pi pico w.

Also Quesition 2.

Can a raspberry pi pico act as a receiver (to receive the modifications to be made to the bluetooth mouse input) while also being connected to the pc as a mouse.

Sound Monitor w/ notification

Hi all,

I'm wondering if any of you could help. I'm a complete novice but wanting to see if what I would like to do is even possible.

I would like to be able to install some decibel meters in numerous rooms that could send a notification to my phone if the level gets to high.

It is over a large area that has wifi in most places. I don't want the sound recorded but would want to know which reader set off the sound.

Is this possible? If so would I need 1 pi per sensor or could they all go via 1 pi?

If not pi, Amy other suggestions?

Thanks so much,

Oli

Capturing PWM signal

Hi! I'm currently working on a project for my Uni. We have to capture a PWM signal coming from the backlight of a display with a PIC16F152-series microcontroller using a CCP module and read this signal on a Raspberry Pi.

As I am relatively new to microcontrollers (I only got to write simple programs for MCUs), I have no idea where to start. Should I use SPI or IIC to connect my PIC to RPi and what could it look like? Should I use both of the CCP modules or would one suffice?

Thanks for your ideas!

Cheapest Audio Output/Speaker solution for RPI Zero 2W?

I'm looking for a cheap solution for audio output/hardware for the Raspberry PI Zero 2W. Currently the RPI Zero 2W has an Mini HDMI, which should give sound. Is there perhaps a cheap way to get the sound out of the Mini HDMI to a Speaker? (I can't use a monitor since the RPI will be placed in a very small space in the fuse box)

iPhone 5s mini only takes 0.148 W versus Raspberry PI for audio repeat?

I have an audio file that I want to play in infinite loop. I wonder how much iPhone 5s power takes if I keep it on the charger?

I've found out that it has the Li-Po 1560 mAh, non-removable (5.92 Wh). Audio playback: Up to 40 hours

So I assume: Watt Hours = 1560 mAh * 5.92 V / 1000 = 9.2352 Wh .

Average Power (W) = 5.92 Wh / 40 hours ≈ 0.148 W

Is this calculation correct?

Two way controller communication between console and controller for pressing buttons using a pi 0 or pico?

So I am working on a project and would like to wire an old ps3 controller up to an old handheld console. I've looked online but can't find much except for wiring controllers to PC. Would it be possible to put one board in the controller and the other in the console and have them communicate button presses with one another? Any advice would be appreciated

OpenMediaVault and HomeAssistant in the same raspberry?

Hi guys,

I currently have my raspberry pi 4 set up via OpenMediaVault in order to use the raspberry as a file storage server for Plex, and I would like to know if I could also, somehow, configure HomeAssistant.

I have a couple of webhooks created through IFTTT but unfortunately this week they become non-free so I have to find a workaround.

On the official HomeAssistant website they explain how to install it on a raspberry pi using a specific HomeAssistant OS, but I already have an operating system running with OpenMediaVault (Raspbian 11).

If you don't mind, could you tell me if it would be possible? and if so, how?

Thank you
