I know people have run the pi2 off standard usb without issues (using no peripherals) but the recommendation is to give it a power source that can provide 2.5 amps. I ran my pi2 with pihole for years on a 1 amp iphone charger.

My Pi Zero 2 is pulling 2.75W of PoE with a load avg of 0.50. It's fetching 1 jpeg/second over the network and showing it on the HDMI port. Based on this, I would guess that the Zero 2 will be ok running off a 1.5A USB-C port, but will probably not work reliably on an old 500 mA USB2 computer port. e: UCTRONICS Raspberry Pi Zero USB Ethernet/PoE Adapter is the best way to power a RPi Zero with PoE. ryanrs fucked around with this message at 15:39 on Oct 28, 2025 |

VictualSquid posted:I am trying to find sbcs that run on generic USB(PD) power supplies. I do love the classic pi0w for that, it even runs from a data port. Libre has a rockchip SBC that's like halfway between a Pi4 and Pi5 in grunt, and does real USB PD. VictualSquid posted:I suppose there are hats to add the capability to most pis, but I would prefer something that comes with the feature already available. Pi 2 & 3 should definitely be able to run from a generic power supply. I have my Pi3 powered by a dumb DC-DC converter. All you need is one of the (many) USB chargers / bricks that are happy to violate spec and deliver more amps. If a tablet charger wasn't giving them enough juice, that is probably because it's got something that limits power -- either by USB-PD, the older USB-BC, or some semi-proprietary trick. Pis don't do negotiated power delivery, they just draw more power and then throttle themselves if they get voltage droop.

My experience with early Pis and trying to get away with cheap lovely power bricks is that it's just not worth it. The brown outs are inconsistent and cause really weird issues, like say the network driver not starting up properly, and burned more of my life than I want to think about, as well as causing a deep mistrust in the reliability of these things

Yooo... If it has cameras, to keep in the spirit of your "roll your own custom TV channels" use it to make your own lovely public access channel of like your cat's favorite hangout spot, your bird feeders, put it in your kitchen and make a lovely cooking program, the sky is the limit!

Finally set myself up a pihole. Ended up buying an older 3 to just leave behind my router. Seems to be working so far!

Just wait to see what most of your traffic consists of. My TV phones home hundreds of times a day, and you can block it.

Further to my previous post I’ve used one of my old Pi’s to set up a Pihole, annoyingly the Sky Router my provider gave does not allow you to change DNS server or turn off DHCP, I can direct individual devices to the Pi but it’d be nice if I could have network wide coverage….any ideas?

If it is just a router then getting your own router to replace theirs would be my suggestion. If it is a router and modem combo see if you can put it in bridge mode and then put your own router behind that.

Ahhhh that’s a shame, I was hoping there might be a work around, it was only due to having a surplus of pi’s that I decided to set up a pi hole, it’s only a few devices that will benefit I’ll hopefully be able to point them at the pi directly

You could turn the Pihole into a router have it serve DHCP and DNS to your network. You might need to get a beefier Wi-Fi adaptor since the pi chipset wasn’t meant to act as a heavy duty network gear. https://raspap.com

I think a better use for a rpi network appliance is actually as a tailscale endpoint. A bit more difficult to set up but it helps immensely when on traffic restricted or public networks. Also access to your home servers while remote on VPN is great.

Is there any project that can essentially duplicate Chromecast or similar functionality? Chromecast itself is great - I can cast to my dumb projector from any device, and it also connects to some Bluetooth speakers. But it's steadily gotten more broken and full of more stupid poo poo. But I've got a bunch of Rock Pi 4s with eMMC that should hopefully eliminate some of the corruption issues that would happen with my home theatre setup that's just attached to a light switch with the hard power cuts. This should be a solved problem, just everything sucks

what are you trying to do? remote desktop: vnc, pick your flavor there's at least 100. if you're on Windows and admire arbitrary restrictions, rdp audio/video: vlc, which is secretly what s lot of commercial stuff sits atop remote windowing, abstractly: x11 you can mix and match, and use magic packets to awake remote hosts etc too for a home theater I'd just invest in HDMI over Ethernet, your remote hdmi port doesn't need an arm cpu and Linux to computer janitor

Probably has to stream over Wifi. Sorry, that was a Critical Requirement that I neglected to mention.

I miss having a nice chonky menu I can control with a 6-button remote control, but I don't miss it that much. Maybe when the current hotness devices get well and truly enshittified, somebody will come up with a nice replacement. Here's hoping.

ante posted:Probably has to stream over Wifi. Sorry, that was a Critical Requirement that I neglected to mention. You need to share more about what you’re actually trying to do. There’s a lot that Chromecast does for you, especially when it comes to validating interoperability. Just saying “I want to replace Chromecast” doesn’t go into enough detail. There’s a good chance a Pi won’t be the best solution, either, although you might be able to make one work. Streaming video is not easy and it depends on having the right hardware codec support for anything with a Pi or Chromecast-sized brain. The Chromecast certification process makes sure that all of that is in place for you. Go outside the Google garden walls and all of a sudden it’s up to you to make sure it’s working at more than one frame per second. If you want to stream PC games then try to get Moonlight or Steam Link working. This generally works pretty well but it’s very much a “set up both ends” thing rather than an “automatic setup is built into the world’s most popular browser and tons of different devices” thing. If you want to cast your desktop from a Windows (or in some cases Linux) desktop PC, or do screen mirroring with some Android devices, then you probably want a Miracast receiver. You can kind of do this with a Pi but you’re probably better off with a standalone receiver dongle. Note that this often has weird issues with DRM for streaming video playback, especially if you’re using one of the Pi receiver setups. If you want a “wireless cable” then there are some wireless-HDMI-transmitter dongles out there with varying degrees of jank that might work for what you’re trying to do. If you’re trying to do anything with Apple devices then an Apple TV is a great one-click solution with lower-than-average hassles (especially when it comes to casting DRMed media), but you basically can’t ever leave the Apple walled garden.

Sure, here is the sitch I've got a projector attached to my ceiling. There's an AC outlet on the ceiling right next to it, controlled by a light switch. The projector is an old dumb projector. Currently, I have a Chromecast connected to it, and it's almost good, most of the time. So I hit the light switch, the projector and Chromecast turn on, and the Chromecast connects to my Bluetooth speakers that are positioned around my couch. I can cast movies to the Chromecast from my computer or laptop or phone, and when it works, it works. That's all I use it for. YouTube works well, piratey streaming sites work very occasionally, and stuff streamed from my hard drive have a weird stuttering bug. Ideally, I can just stream stuff, somehow. I don't want a full media centre, and I don't use smart TV features. It's a once a month, play this movie, gently caress technology thing. I'm willing to Linux janitor a solution once, if it solves my problem for the near future

It's a perfect use case for Android TV box. Those are like chromecast, but actually usable.

I have the Sony HQ camera v1.0 that I just got from my brother for helping him get his later one working. It doesn’t have a lens. Supposedly it will take c-mount plus I do have the c-cs adapter… Any recs on what lens to get? I’d like to take clear picture of the skyline from our house near downtown for time lapses of that helps. I really don’t know much at all about photography.

Arducam (basically the go-to brand for sensors and lenses) also has a 5 lens multipack for ~$110 on Amazon, but I bet you could get the same packagefor $40 cheaper on aliex/temu/etc: https://www.amazon.com/Arducam-CS-Mount-Raspberry-Lengths-Telephoto/dp/B088GP9K4T/ E: If I knew what I know now back when I was experimenting with these lenses, I think I'd have actually bit the bullet and bought this one, as the range of focus and glass size is more versatile than any of the 3 lenses I currently have: https://www.amazon.com/dp/B088GQHVY3 spookykid fucked around with this message at 07:56 on Nov 25, 2025 |

We have some 35mm camera lenses that we don’t have the camera for that might be worth trying. We got them in an auction lot. If space was an issue that wouldn’t work but it won’t be for this at least. Thanks again
