Is something like this what I need to be able to use a rpi to turn power off to 110V devices? That's really just one of my first Googlin' results, so if there's anything good or better tell me what it is! This isn't for anything important, I'm just wanting to do a little project for fun to let me turn some things on/off programmatically.

I just got my HDMI splitter/passthru ambilight thingy working. I'm pretty pumped about that. I haven't done an electronics(ish) project like this in 20 years. So now I have my Shield HDMI hooked up to an HDMI splitter. One of the outputs goes to my TV and the other output goes HDMI-to-AV-converter > AV-to-USB-device > Pi 3B. Got a strip of WS2801 LED lights around the backside of my TV hooked up to the GPIO on the Pi and using Hyperion software to capture from the USB thing and control the LEDs accordingly. I've still got to adjust the white balance and stuff, but I'm just relieved my soldering skills didn't screw it up. For those unfamiliar it looks like this randomly-googled video: https://www.youtube.com/watch?v=ur0HDE-U7vw

Just Google bias lighting. It's mostly not noticeable, that video just picked some scenes that pump up the wow factor. Or maybe you wouldn't like it, who knows.

What kind of runtime can I expect out of a Zero W running on a usb battery pack? Thinking about making a timelapse camera. Obviously it'll depend on how often I'm taking pictures, if I'm uploading, etc, but anyone have any experience running any Pi like this?

Hadlock posted:Wow the Zero W is very competitive with the A+ plus it has onboard wifi and Bluetooth. I've never been able to setup a TCP/IP link over Bluetooth but it looks like it'd make a great low power robotics controller. My A+ had a janky 4 port unpowered hub hanging off it to do wifi (general file transfer) and Bluetooth (PS3 controller) FWIW, I picked one up at the Microcenter in St. Louis, MO. They had dozens of them just sitting in a basket for $10.

xtal posted:The important part I forgot to mention is the remote server that handles editing and compilation. All my Pixel has to do is shell in to an on-demand EC2 server with tmux, vim, Haskell, Rust, etc. This is pretty much an Android thin client since I live inside the console -- all the phone has to use is JuiceSSH. But trying to compile Haskell or Rust directly on the phone is admittedly impractical. If all you're doing is SSH'ing in I see no problem with it.

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?

Hadlock posted:Edge connector needs a socket, and then you attach wires to... What exactly? Another header set of vertical pins on the motherboard? Header pins are great because they're the smallest object a human can hand soldier a wire to, they're the universal interface for home projects for a reason. The point was that if you wanted to attach wires you could use a header with a socket, and then modules wouldn't need any soldering. Just seems like it'd open new markets for them.

I have the tools and the ability to solder it on, but I've done about 30 minutes of soldering work over the past 20 years...I'm super slow, messy, and not confident in the results. In other words there's a huge required-skill-level difference between a hammer and soldering.

Two questions: 1. Is the Zero W fast enough for real time face recognition? I have no experience in this field but I'd like to begin dabbling in some computer vision stuff. 2. Can anyone recommend a case that fits the Zero W (or whatever is fast enough for face recog) and the camera? I guess it'd be cool if it had some provision for mounting, but I can jury-rig something... edit: The answer to 1 seems to be "not really"...it can do about a face every 5 seconds. That's when it's trying to recognize the person (comparing to just one known face) from the face rather than just detecting faces. Thermopyle fucked around with this message at 20:51 on Nov 9, 2017 |

I put the official Doom wad files in the right folder, but I don't know what to do next. The website tells me to make a nano script but I don't even know what that is, this is the first time I'm using Linux at all, so how do I get it to play the official wads? This doesn't have anything to do with the Raspberry Pi. Maybe there's a zdoom thread, but you'll probably need to find if there's (un)official zdoom forums.

Sweating pipes is a useful skill to have, but there is a hammer header equivalent for pipes: sharkbite fittings...and they're way more effective for pipes than hammer headers are for raspberry pis!

McGiggins posted:I get it now, it's a controller for "dumb" hardware that more or less isn't "smart" hardware that can't be directly configured at a software level by the pi itself without this intermediary. yes If this helps: Imagine a light switch on a wall. Take away the switch/paddle part. Replace it with a port the raspberry pi hooks up to. The raspberry pi can now turn the switch on and off.

I'd like to use a zero as a sensor for various things. There's power but no wifi or internet available at the locations I want to do some sensing. Obviously, I could get a regular cellular hotspot, but thats pretty expensive for the super low data rates I need. To make a guess I just need to do an HTTP request like once every 5 minutes with a few hundred bytes. I feel like I've seen ... things ... that maybe use GPRS or something for this type of use case, but I can't really remember any details. Any ideas?

Those all look like decent options. Right now I'm thinking a GSM modem with an AT&T IoT SIM is going to be the cheapest...but the most effort. I can ebay usb modems for less than 20 bucks and AT&T IoT plan with SIM and 2MB of data for $2/month. I think most of the effort will be involved in finding modems that will work with the pi and linux.

mod sassinator posted:Yeah it might be easier to get a cheap little hotspot and swap in the IoT / whatever SIM card. Then you can run a simple wifi network for the Pi or any other nearby devices to talk to and send data. In my experience it's much, much easier to configure linux with wifi vs. GSM modems. With GSM you're dealing with crusty old PPP stuff in Linux. It can work but you're going to be reading 20 year old man pages and readmes from back in the modem dialup days that may or may not be relevant anymore. You're also all set when when one sensor turns into two, three, four, etc. Oh, that's a good idea. fishmech posted:GPRS/plain GSM/EDGE service is in the process of being discontinued by all North American carriers with all the major American cell carriers that used to provide it having turned it off. Because of this, there's a lot of cheap equipment for these 2G technologies being sold which won't actually work but people are trying to unload quick. Good point, I forgot about that. In case anyone is curious about my use case: I own a few of my own and manage somewhere around 250 rental properties for other people. Because of the large number it's not uncommon for some vacancies to sit for months without a tenant. I'd like to be able to know if the electric goes out or the furnace stops working or if there's a water leak in any of these empty apartments. Thus the idea of a raspberry pi monitor.

That's a neat project. Kind of makes me want to make one. What kind of delay between images are you going to use? I wonder if you could get or make something that powers the whole thing off for X minutes and have it take the image on boot and then shut down. Maybe the power savings (if any) wouldn't be worth it...
