I'm not sure a pretty clean lookin dude playin with a bunch of expensive electronicals should be calling himself Basically Homeless but its pretty funny we finally found a screensize the Rpi Zero can game on reliably.

Does anyone know what the part is for that screen? Something that small that is apparently 640x480 sounds expensive.

Oh looks like they're for AR/VR things. That's pretty cool let me buy a cou- $510??!? Holy poo poo. Makes sense that they'd be that expensive though.

yeah, cameras of similar size are also turbo expensive. So like if you wanted to DIY your own Apple Vision dealie, its still pretty pricey but we def live in an era when billionaires could DIY their own aerospace surveillance programs, as a hobby. coconono fucked around with this message at 04:15 on Apr 4, 2024 |

Good news, this one is 1080 and is only 450 dollars with the driver board. Though no little lens for actually seeing it though. https://www.displaymodule.com/produ...2QVsdK8lUO4SeII

Whoa, so I thought 1000 nits was super bright, and I'm pretty sure it's at least enough to view outdoors in direct sunlight. I looked it up and even the iPhone 15 maxes out at 2000 nits. This screen can go one third brighter. Doesn't seem safe, having something like that a couple inches away from your eyeballs. Why they do that

if the lenses are anything like the ones used in VR you lose a lot of that brightness to the optics before it gets to your eyes

I have a pi3B and an original pi running with an hdmi to AV adaptor and an arc Modulator for each I currently power them using a 4 port usb charger plug for the adaptors and modulators and an individual power supply for each pi. I’d like to reduce this down to one plug for the lot with a view to add more pis (with adaptors/modulators) in the future…. What’s the best way to go about doing this????

What are the power specs for the adaptors? Just power those from the usb ports on the Pis if they're low power. A hdmi-av dongle shouldn't need more than 500ma. I have no idea what an "arc modulator" is, that isn't even on google. Then power the pis with a decent-quality 5V/2A multi-usb power supply (look on amazon for like "usb charging station" and get something with at least 10W per usb.)

Gaz2k21 posted:I tried powering from the pi’s that didn’t seem to work, they’re RF modulators…. ok looking it up: here's the spec If you have an original Pi B you're screwed, they have super-limited USB power. The B+ can do more power, but you have to set a configuration option to get that. Otherwise you're limited to 600ma output. And the 3B should always have 1200ma available shared among all ports with no extra steps needed. So if you tried powering the devices from the 3B and it didn't work you're somewhat screwed, I'd guess the 2 devices combined draw more than 1200ma. (Or you have the 3B on a 1A supply.) I'd figure you could do at least one of them though. Anyways you should be looking up the specs for your devices, this is simple addition once you know how much power the things use. eightysixed posted:It's what you use to get to 1.21 gigawatts and go back to the future, duh oh, so you need a Pi 5 power supply for that?

Yeah, they created a new USB-C PD 5V/250MA profile for it.

Is there a reason why the raspberry pi devices are on their own power supply? You may be able to get away with putting it on the same outlet as the other devices. Maybe hang one of the usb devices off the raspberry pi if you need to make room.

Zero-size SBCs with not-Broadcom wifi? I'm looking for something in a RPi Zero form factor, with a well-supported wifi chip and a U.FL or SMA connector for an external antenna. The RPi Zero 2 W fails on both these grounds, so I'm not that excited about using it. Are there boards from other companies that are similar size, with non-Broadcom wifi? I don't need good range or throughput on the wifi, I just need the connector so I can get the antenna outside the metal enclosure. I would like to run OpenWRT (even though this won't be running as an AP).

OK, both those appear to use the AP6212 wifi module, which I think has Broadcom guts. But hearing that they really do work on an open source OS like OpenWRT is good news. That opens up a lot of not-RPi boards for me to look at. Thanks!

A few months ago I was somewhat defending the 5V 5A power supply the Pi 5 has, but I have now learned it's stupider than I thought. PPS, Programmable Power Supply, was standardized in 2016. This is the feature you use to select custom voltages and currents. This is the way that more and more supplies are able to deliver 5V 5A. Pi 5 does not support PPS. It needs its power supply to explicitly offer that profile by default, which as far as I'm aware roughly nothing does.

Collect all three!

My Dad has failing eyesight, and has recently been getting me to unsolder/solder some chips and capacitors (like twenty year old ic’s from offset printers). I don’t know much about electronics, but am enjoying myself and it has sparked my interest in doing some basic learning. I know my single RPi 0w is not meant for learning electronics like an Arduino or even a breadboard, but I sorta don’t know where to start. I’ve seen it discussed in this thread as an adjunct to the RPis and just thought I’d ask here since I’m phone-posting and don’t have search: 1) Do we have a basic electronics thread for ignorant newbies? 2) Would it be out of line to ask here for recommendations for a basic kit off Amazon to get components & tools? I have a pretty good soldering gun and some multimeters already, but don’t want to spend $100 on a giant box of resistors when I’m just starting out. I figure some of the Pi discussions are from folks also involved in building related doo-dads and widgets. 3) Are there some true-blue books/websites or even subreddits for folks to learn the basics-for-Dummies? I know I could Google, but such a broad topic would make Google’s poor search results choke. Free is preferable while I’m still trying to see if this goes anywhere with me. My 0w was for a PiHole a few years ago, and I have basic Linux competence with Debian-based and Raspbian from 2020ish. Thanks for any links or advice, again apologies for just asking instead of waiting to get home and start searching and looking for a basic setup.

I know this isn’t amazon but if you’re lucky and you live near a Microcenter, they have cheaper boxes of a variety of parts that might work well for hobbyists, including components such as pir sensors, temperature sensors, resistors, capacitors, diodes, and so on. Also, I find that sometimes an item will be on ebay for cheap and will include free shipping. So if you need a cheap $3 part and don’t want to pay another $3 to ship it, ebay might work in a pinch.
