raspberrypi

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:

Hit:1 http://deb.debian.org/debian bookworm InRelease

  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

I don't get a very detailed error message but it fails and tells me to try reinserting it. I've tried a few times. It fails at different percentages sometimes. Any thoughts or ways to get a more detailed error message? I have Mac and Linux too.

So I've got an 8GB Pi 5 with the offical Active Cooler and then the Pineberry NVME HAT on top in the Pi52 tall alumnium cooling case and thermals are not great. Looking for guidance and/or recommendations.

I already have the active cooler so I'm all out of fan headers, and I have 3 hard drives plugged in so I'm not sure about powering a whole USB fan.

I saw that Noctua finally came out with their desk fan and thought that may be a perfect solution. I was thinking of just slapping it under the Pi, but I was wondering if this would even make a difference.

Also wondering what the best configuration would be between push/pull & bottom/top or if anybody has better ideas, I'm all ears. Thank y'all!

Hey all! I wanted to build/buy a retro gaming console with Raspberry Pi to play roms. What is the simplest way to do this? Can I buy a Raspberry Pi that has RetroPi installed already, then just dump my roms onto it?

Thanks 👍

This seems really cool to me.

DietPi is an excellent ARM SBC debian distro if you want to run a DIY NAS/media server/Pi-Hole/torrent platform.

They have a great set of CLI tools to cover most common use cases for a headless device. Personally, I found their tooling to be a great introduction to CLI linux. The baseline tools have you covered, but you can start experimenting once are comfortable with linux CLI (and you need to implement some custom solutions).

One cool feature that it has is that logging is done in RAM, thus extending the life of your SD card.

I've been using DietPi since 2018. For a relatively small distro (about ~100K users), they are very active and responsive on their communication channels.

"Raspberry Pi Ltd, a leader in low-cost, high-performance computing, announces that it is considering an initial public offering (the "IPO" or the "Offer") and that it intends to publish today a registration document (the "Registration Document"). The Company is considering applying for admission of its ordinary shares to the premium listing segment of the Official List of the FCA and to trading on the Main Market of the London Stock Exchange ("Admission")."

I have a Raspberry Pi 02W running Pi-Hole and ordinarily things work perfectly, but I've got something in my house tripping my fuse box which I'm unable to locate. The tripper, not the fuse box. Anyway, what it means is occasionally, I lose power and so my router and my Pi-Hole go down.

I've configured my /etc/dhcpcd.conf so that my RPi02W can have a static IP

interface wlan0
static ip_address=192.168.1.100/24
static routers=192.168.1.1
static domain_name_servers=194.168.4.100 194.168.8.100

And have rebooted to confirm it's fine, and it's fine.

However when the router goes down and I bring everything back up, the Pi-Hole can't reconnect to the router. I can log in to the router and see it connect briefly, but it's only briefly and then nothing. I even try enabling DHCP on the router and it still refuses to reconnect. Ultimately the only way to get it to reconnect is to factory reset the router, change the password back to my usual password, wait for the RPi02W to connect and then disable the DHCP again. Needless to say it's a pain in the arse.

What am I doing wrong? How do I fix this?

#Solution I switched the DNS servers from Virgin Media to 8.8.8.8 and that seems to fix it. Not sure why, but it does.
