Thought I'd screwed up everything because the light wasn't blinking and Atom's serial monitor spit out errors, but connecting via the OSX terminal did the trick and everything was working as expected.

xtal posted:I want to stop using Raspbian for my little projects and switch to using plain Linux with init=myprogram and no process management. Is there anything that exists that takes in a binary program and gives me a bootable Linux image with it as pid 1? (Would it be helpful if I made it or are there better ideas?) What exactly do you want to do? I guess you want the core services of the Linux kernel and nothing else or something? Or are you looking at using it as an overblown uC or a quasi RTOS? It's probably no use to you but there's Ultibo. It's kind of a framework for writing your own embedded stuff on a Pi. But it's Pascal.

eschaton posted:Easier to translate into Ada that way! So this is only sort of related, but I was messing around with my Orange Pi PC that is running Armbian Jessie with a legacy kernel (so hardware support but age and OEM shittiness). Past a certain window size X gets slow when it comes to window dragging. I was looking in the XFCE settings to try to change it to window outline style dragging and found the compositing desktop option. Expecting it to poo poo itself in an interesting way if enabled, I enabled it. You know what? It loving worked. I turned it back off again because there's bound to be some horrible side effect but it made everything more responsive and dragging windows worked perfectly even with larger sizes. Probably a silly thing to be amazed by but I never thought of a compositing window manager working on an ARM SBC. So RPi related content. My Zero is out of commission because the mini HDMI adapter fell apart. The Pi B is acting a little "off". I caught it with a couple of corrupted characters on a window title. Uh oh. The Pi 3 with the DAC and the tube preamp: Haven't been using it for reasons that aren't even clear to me. Something I do want to know with the RPi(x), is whether SDL can go xorg-less and just run in the framebuffer like OpenGLES can? It'd be awesome to have some ported things which don't have to deal with the overhead of xorg. And for some bizarre reason I'd love to run NetSurf framebuffer version fullscreen. I guess I miss the awkwardness of using Arachne in DOS in the '90s on super lovely hardware.

Buildroot might do what you want (though I've never used it to make a pi image, but there seems to be people who have from a quick google). It lets you configure every part of the root filesystem.

It's in my options but then I thought I could also use Plex which also works on Pis but Android does it much better than either of these, I think. And more.

Android on Pi3 is a thing but it kind of sucks. It's in a pretty similar state to Android on x86 where there are a few random somewhat insular projects, often out of Asia, that coordinate on Yahoo or Google groups and don't really have a critical mass of developers.

The problem with Android on any Raspberry Pi is that the GPUs are way too old and slow for current versions of Android to be happy with, and when you force it to work anyway you get a pretty choppy experience.

Anyone able to comment on the quality of the Raspberry Pi camera module? I'm considering setting one up as a security camera. I intend to use https://kerberos.io/ as the software. I want it to be able to actually see defined features on someone's face. It's really common here for people to have a video camera running and it looks like someone smeared vasoline over the lens so it's impossible to see features and identify a criminal. Ironically I'm doing this because someone broke into my house and stole a few Raspberry Pi I had laying around in addition to some other assorted poo poo.

It's not going to be good enough quality to make out features on someone's face though, it only captures video at 1080p and has a somewhat narrow field of view. Mounted up in the corner of a room you could probably see what's happening inside it, but not much more than that.

YouTuber posted:Anyone able to comment on the quality of the Raspberry Pi camera module? Literally just set up motionpi with the original mk1 pi cam I had hanging around. It's bad for low light handling and FOV but is very decent for well lit narrow areas or indoors. I'd recommend buying the newer non-IR filtered wide angle sensor cams which are now available plus one of the cases which have camera mounts on them.

Just use an IP camera and be done with it. Raspberry Pi's aren't reliable enough (IME) for that kind of usage. You can get decent IP cameras on Amazon for ~$50. Better ones are around $100. By the time you buy a Pi, a camera, power supply, an SD card, and a case, the IP camera is a better deal. Just set up your router to reject all internet traffic to/from the camera.

Something's bothering me. I'm using a Seagate Backup Plus drive, or something like that. This issue isn't specific to the particular type of USB drive anyway. It's done it with a different model Seagate and a 60GB USB ATA notebook external HDD thing. Any USB HDD I have plugged into the Pi 3 seems to make a "tink!" every so often even when completely inactive. I haven't seen that behaviour with anything else. What the hell is the Pi 3 / Raspbian doing? There's nothing relevant in dmesg. It's an externally powered desktop drive so it's not a power issue. It also works fine with the Orange Pi Zero,Orange Pi PC and Orange Pi PC2. I swap SBCs a lot depending on what I'm doing.

Is it the hdd heads parking? I had an Ubuntu system like 8 years ago that was super aggressive with its head parking settings, and I had to futz around with hdparm to get it to quit doing that.

This got me wondering, and yes, at least one person has gotten Android running on the Jetson TK1 y'know, just in case anyone wanted to pay $200 for an Android SBC. I bet that might actually perform OK though. If not, well, the Jetson TX2 is only $540! 256 cores of Pascal goodness...

Can anyone recommend some good Pi and Scratch tutorials suited for kids. My 9 year old wants to get into programming and I want to teach him teh basics adn Scratch is pretty sweet. But I'd like some lessons so we can work on things together at his level. The "android flashing antenna" from the Pi resources page was right down his alley (I wired it up and explained the code to him as we did it together.) I'm wondering what stuff in scratch there's out there for him so we can walk thoruhg some lessons. I dug into node-red a bit but I think that's going to be a bit above him for now.

Arrow hosed up processing my free Raspberry Pi 3 promo order so they're giving me a free Zero W. Anyone know where to get the absolute cheapest 2x20 header for it? I don't feel like paying Adafruit $5 for that. Or at least some kind of very minimalist kit that includes the header. edit: after using different search terms I found this Malloc Voidstar fucked around with this message at 01:37 on Jun 14, 2017 |

I don't feel like paying Adafruit $5 for that. That's probably the cheapest you'll find in a 2x20, but you could just get one long strip and trim it down to size. I have a bunch of strips that are like 40-50 long and I just break off strips of 20 when I want to work on a new pi zero.

Yeah, it doesn't matter if you have to double them up if you're just going to solder them down anyway, too. Here is enough for 20 Raspberry Pis for $0.74 https://www.aliexpress.com/item/10pcs-40Pin-2-54-Single-Row-Pin-Male-Header-Connector-Strip-for-Arduino-Prototype-Shield-DIY/1927041331.html

For whatever it's worth, Adafruit sells a lot of stuff through digikey, so when I want an oddball Adafruit product I often toss it in with my next digikey order to save on shipping.

I'm basically a know-nothing, but it seems like the Zero W would have been better served by an edge connector like what you see on PCI cards or whatever. Then you could just slide headers or whatever module right on the thing. Am I wrong?
