I finally finished my timelapse + camera remote shutter project and despite the case looking amateur as gently caress I'm content with it. It assembles easily, it's got a gopro mount, and it's as small as I could make it given the stuff I had to cram in there. Additional features are the camera module 3, a UPS and an RTC. The UPS so when I forget to shutdown before I turn my car off it won't lose power, and the RTC because precisely timing photos is kind of important when doing eclipses. The big red button is to shut the system down immediately and the slider switch is to turn the UPS off/on. The LED is just for an additional blinky status as it can update a lot faster than the epaper.  The epaper even shows a snapshot from the camera so I can compose the image.  It's very much a form follows function build, everything is off center or stupid looking because that's the only place it would fit.

I'm extremely skeptical of the raspberry pi IPO, what's the stated goal here? I need to look more into it, are they raising a bunch of capital with the plans to make many more products? Will more capital let them avoid the manufacturing problems they've had? Why public? It's going to make more work for them and if the core vision is to keep prices down for hobbyist computers, I just don't get how this helps.

They make several form factors, I just picked the one that is the same size as the zero. And yeah, I have a udev + systemd unit that detects when I plug in my SSD drive and it fires up a script that takes images at set intervals.. so it's purely for doing timelapse stuff. The only downside is the pi can't read stills off the camera very fast, at full rez it can take a still every 1.3 seconds. I have it set to capture at 1280x720 so I can take an image every 0.15 seconds. But 720p is fine, it still makes a nice little video. https://i.imgur.com/gRO04xu.mp4 (driving into a storm as I crossed the continental divide near Denver last fall)

I didn't know I wanted this but now I sort of want to build something similar for my wife to use recording her assembling puzzles does it just sit there recording if you park for a while, or do you detect a mostly-fixed image and step down the rate?

I wanted it to just work without any input so that's where most of the effort went. There is motion detection stuff out there though so I'm sure fancy features are possible. Upside is each frame is only 270kb so a 500gb drive can log an absurd amount of time.. like 80 hours or something. The script that does the actual work is only 66 lines long: https://github.com/mrxzzy/rpi-timelapse (the epaper stuff is another repo)

Hopefully someone knows this, but is there a name for that type of mount? The 2 rounded tab things with the holes in them, like you'd attach to a GoPro mount?

Yeah, gopro invented it so it's just "gopro mount." Same thing happened with arca plates for cameras.. named after the company that first made them.

I am guessing that they want to stop relying on whatever 3rd rate cut down SOC Broadcom throws at them. Also larger capital allows for more favorable part acquisition.

pi 5 trip report: compiling and running GZDoom source port. https://forums.raspberrypi.com/viewtopic.php?t=354301 guide says "The GZDoom source code will compile in about 30 minutes (on a pi 4)" ... didn't clock it, but I'd say it was less than ten minutes. Nice. nice. nice.  Odd thing, doom 2 took about five minutes to load. Like GZdoom had a long shader compilation step. Seems like a bug. Other thing I notice. In chromium, you can go to youtube and and click on any video to get "Stats for nerds" and you'll typically see frames dropping every second, all while the CPU usage is VERY high - like the smoothness of the mouse movement is affected. Browse to this and compare to a desktop vs pi and you'll see some things are hardware accelerated and some not. code:One workaround is to open VLC Crtl+N and paste in that link. Takes longer to buffer (and you should increase the network + disk buffer length) and seeking through a video is broken. But VLC takes less than 5% a CPU of a single core. You wouldn't know it's there. Twerk from Home posted:I'm extremely skeptical of the raspberry pi IPO, what's the stated goal here?

Maybe it's a Mozilla thing where there's a commercial arm and a foundation arm. (Both of which kinda flail around uselessly  but thats beside the point) Then again, I don't know why ARM (chip designer) went public after several, uh, decades.

Pi 5 has very limited video hardware decode, and no encode at all. It only does h265 decode. So the pi 5 sucks as a youtube device.

Takes longer to buffer (and you should increase the network + disk buffer length) and seeking through a video is broken. But VLC takes less than 5% a CPU of a single core. You wouldn't know it's there. VLC can't get dash streams, so it's limited to format 22 streams which are 720p30 and have h264 encoding. The thing that makes it work is that 720p30 is a very easy target to hit. (Also VLC is more efficient than a browser.) If raspbian is still including h264ify, you actually don't want that. VP9 is easier to decode on CPU than h264. 4k is still gonna suck in a browser though. What might work best is MPV, which can directly stream youtube using yt-dlp. So if you have both mpv and yt-dlp, you can try this: mpv --ytdl-format=313+251 "https://www.youtube.com/watch?v=Tos8lrigtXw"

I have a few pi4's in a kubernetes cluster with the poe hat and it's super random whether they're loud or not. I have one in the cluster that never makes a noise and the other one spins the fan up and down every few minutes 24 hours a day. It's not even related to their position in the case or airflow either because I moved them around trying to find a pattern. I feel like it's a dodgy sensor or quality control issues. As for killing off the fan entirely it'll probably be fine but I guess the details depend on how hard the cpu is working. As long as the hot air can escape it'll probably survive. And if the cpu starts throttling.. well you know you need some fans.

Buddy if you thermal lock your Pi4 with Pihole then you’re going to be having way way way larger problems than just heat. That said, I could see where the PoE aspect could generate enough heat to warrant a fan so idk.

eightysixed posted:Pi4 for PiHole is way overkill. A 4 has enough grunt to do pihole and other stuff too. Mine is also a wireguard server and NAS for my MP3 library. Note that the 4 can boot from USB media. If you've got a spare SSD lying around you can totally sidestep the technical Achilles heel of the pi family.

I have been considering picking up a pi5 for the sake of PiHole since it seems like the most elegant solution for how frustrating ads have become, but if that's overkill, would I be able to use it for other purposes simultaneously? Like what other things could I be running at the same time on that?

Pi 5 performance is comparable to the Atom-level chips, far beyond what Pihole needs. You could set up a console emulation frontend like Retropie, a file server, a container sandbox, a VPN gateway, or lots of other things.

I felt like I really needed to understand the underpinnings because so much of what I do at work relies on k8s but I've mostly only ever been a user. And a pi cluster was actually the cheapest way to get into a bare metal install.. like $100 for the poe hats and a poe switch, had everything else.

I'd also argue that if you want to do those things too, you'd be better served by the Intel chip given that they cost the same amount as a Pi 5 anyway and come with an nvme SSD instead of SD cards or a USB SSD.

Yeah, I agree. You don't even need to spend as much as a Pi 5 if you're willing to buy used hardware - Wyse 5070 is around $50. It doesn't have NVMe support but I think M.2 SATA is more than adequate.

He was forced to concede performance per dollar is loving awful for the pi, but then charted "performance per power usage" to try and salvage anything the pi might still have going for it.  Wow 135 geekbenches per watt is so much better than 93 geekbenches per watt! This is definitely not a contrived statistic that 99% of people don't give a poo poo about! Even with the Pi 5's higher efficiency it still has thermal issues that require an active cooler, in the video he crams in an NVME hat that barely fits in the official case and blocks the airflow to the active cooler. Like, best of luck to the pi organization with their IPO and their business customers, hobbyists should seek alternatives if the 2-3yr stock shortage didn't force them to already.

Those no-brand mini PCs ship with insane BIOS settings and power limits far higher than those CPUs need to perform well. If you change a setting in the BIOS (or buy a real brand like Intel NUC) they blow away the RPi5 on performance per watt, which they should because they are several silicon processes more advanced.

I give two shits about performance per watt, but I doubt I will ever buy a Pi 5. Seems like there are better options out there for what I'm after. It seems like other companies have tried to go toe to toe with Intel before, and it usually isn't a good long-term strategy. Hell, they even put Cray out of business.
