raspberrypi

I'm thinking about an IoT Polar Aligner. The main idea is to use a Raspberry Pi W with the camera module to find and detect the North Star and display it on the mobile phone. The final goal is to connect it with servos so that it can automatically align itself. Does anyone know of a similar open source project?

I've got a Zero set up with usb0 as g_ether and a static IP address:

usb0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        inet 10.14.0.15  netmask 255.255.255.0  broadcast 10.14.0.255
        ether 7e:24:7d:cc:68:7c  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

I have the OTG port connected to one of the four USB ports on a 4b. I'm not sure what the next steps are to get the actual connectivity to function, though. I've seen posts saying that gadget mode is only supported on the USB-C port - does that only mean for using the 4b as a peripheral, or does that mean for any connectivity, even if it's the host?

As the title says looking for a case that works with the NVME base bottom hat I've looked but not found anything. Just asking in case I didn't dig deep enough any help is welcome.

I have a pi running pihole next to my retro console TV and would like to make it into an ad blocked YouTube player.

I've been looking on and off for a month to figure it out and the only things I find are for RCA cables or for the old way to change resolution from the 2010's.

I am not sure if any interesting ones have been made since focus shifted towards the 4 and 5. Maybe there are some specifically designed around using different HATs like UPS, LoRa, or the camera module.

I'm mostly seeing the average layered 3D printed cases and the mock consoles designed for emulation.

I'd also be interested in hearing some neat projects people are using them for. I have two spares from a while ago that I used for a NAS and an e-ink displayed weather forecast.

I spy with my little eye something something Pi.

Hello everyone, looks like we will start on building our dream home this year. I do want to set up a raspberry for automated photo shooting from the construction site. One picture per day is enough, I do want to create a timelapse video afterwards. The new neighbour is a friend, he allowed me to set up the camera in his house facing the construction site. Only problem he does not have a power supply at his window...

Anyone having experience with a solar module and a battery to power the raspi? Feel free to share your jdeas!

This is a good blog post, with die photos of the new RP2350 chip and a brief description of what they show. There is a link to a 12 minute youtube video that is also very good, that discusses the die shots in more detail and also goes over the rest of the Pico 2 circuit board, including die shots of the QSPI flash chip and the voltage regulator chip.

I remember the last time I tried to find a cheap webcam that works on linux, I gave up pretty quickly and just used my laptop for video calls. Saw this guide to build one with a zero 2, had a spare board in my parts drawer so thought why not. I'm surprised by the quality of it. I've been using it for work meetings.

...at the expense of breaking some commands here and there. Why is that? How come env values can have this much impact in performance "for free"? This MUST have some caveats, right?

Thanks in advance.

We’re happy to announce the launch of Raspberry Pi Pico 2, our second-generation microcontroller board, built on RP2350: a new high-performance, secure microcontroller designed here at Raspberry Pi.

With a higher core clock speed, twice the memory, more powerful Arm cores, new security features, and upgraded interfacing capabilities, Pico 2 delivers a significant performance and feature uplift, while retaining hardware and software compatibility with earlier members of the Pico series.

Pico 2 is on sale now, priced at $5.

I found this tutorial about how to use a raspberry pi to add a digital panel to old cars (canbus port needed)

Just used this for the first time. I know it's dumb and small, but copying my whole setup and moving it to a new quicker SD without any hassle was gorgeous. I truly adore my Raspberry Pi.

Can anyone suggest a plug and play USB mic for my raspberry pi (that you've used and know it works). I've managed to avoid work meetings on teams for a long time but there's one I can't get out of and my laptop broke so I'm computing only on my pi for the time being. Don't really care for webcam, noone needs to see me, but I need to be able to speak to them.

Friends... my new Raspberry Pi makes me crazy!!!

I would like to install Docker on the RPi5 (8 GB). I am following this guide: https://docs.docker.com/engine/install/ubuntu/#install-using-the-repository

However, at step 2:

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

I always get the error:

E: Package 'docker-ce' has no installation candidate
E: Package 'docker-ce-cli' has no installation candidate
E: Unable to locate package containerd.io
E: Couldn't find any package by glob 'containerd.io'
E: Couldn't find any package by regex 'containerd.io'
E: Unable to locate package docker-buildx-plugin
E: Unable to locate package docker-compose-plugin

Then I found out that at step 1:

sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

I receive the error:

  404  Not Found [IP: 18.165.183.12 443]

What I am doing wrong? :-( What am I missing? Why can't this IP be found?

Many thanks! :-)

I can't seem to get it to work. I always get these errors in the terminal when running the spi flash tool that they recommend:

Scanning USB port...
Search usb, timeout set as 3600000 ms

and then eventually an S_TIMEOUT. I think my thinkpad is not even detecting the orange pi at all through usb. Anybody have experience with this. The official documentation is really bad. I also seem to get this on startup of the flash tool:

QThread::setPriority: Cannot set priority, thread is not running
"05-14-2024"
QObject::moveToThread: Cannot move objects with a parent
