Yes, I was thinking that. Should improve the identification quite a bit if you can give size hints.

48% is also abyssmal for most AI algos. If there's a "Don't tell me unless it's at least this high" that would probably be worthwhile. 48% means "I am pretty sure I'm wrong but here's a guess"

That is super cool though, what hardware does it require?

Futurism was an art movement where dudes were all 'CARS ARE COOL AND THE PAST IS FOR CHUMPS. LET'S DRAW SOME CARS.'

The AI is a pre-trained thing I pulled off of tensorflow and all it takes in a 244px square picture. Rolling my own model is on the list but is a very very very very stretch goal.

A few seconds after that picture of the cardinal it took another one of her and said she was a house sparrow with 98% confidence, but for the most part so far even it's lower-confidence calls have been pretty good. And to be fair I'm mainly using it to weed out false positives from the change detector (my arbitrary floor for that is 30% confidence). But since the classification doesn't appear to be a big overhead, I'm going to start slicing the image up and running each slice just to make sure the classifier sees as much bird as possible.

I'm running a 4-B 4GB with the HD camera module. The detection loop hums along at 800x600 @ 30fps, but there's usually a bit of a stutter when it takes a full-res picture. And I'm usually running the web server at the same time.

I need to wire a neopixel strip to a Raspi GPIO
I don't want to solder directly to the GPIO and I think female jumpers are going to be a bit too fragile

What's my best option?

I'm currently thinking of just grabbing a 2x3 header and yanking 3 of the pins out with Pliers so I have access to 5v gnd and GPIO 2/3 and soldering wires to that, which feels kind of weird

hello world

Is there any way that I will be able to watch 1080p youtube videos smoothly in a browser on the pi 4? I have tried overclocking and enabling chromium hardware acceleration but it's still choppy. Videos play fine when downloaded and played back in mpv.

You guys aren't going to believe this, but that guy is our games teacher.


Probably not. Web browsers just aren't very well optimized for video playback. If you have youtube-dl installed mpv (I'm pretty sure) can use that to extract the video stream URL and play the videos directly without you having to download them separately.

I have no issues with playback on my 400, so it's certainly possible. I haven't changed anything in PiOS though so I don't know what if anything I have different to your setup.

Also I finally did what I wanted to do from the start with the 400 and set it up on a small desk of its own and I'm pretty happy to have this little desktop setup in my bedroom now for when I just want to sit in a quiet room and do computer stuff. After getting a new laptop and relearning how to type on these kinds of flat keys I'm even starting to get used to the keyboard and be able to type normally on it.

Question: do you guys use docker on your raspberry? For what kind of things?

Last weekend I bought an external hard drive and so I'm looking into installing/configuring a number of things (raspberry pi 3b): samba, deluge, couchpotato, plex, ... It looks like there's a docker container for all of these things, does it make sense to always use these? Or are there some overhead costs (or other drawbacks) I should be aware of?

I tired to run octopi, a 3d printer controller program that allows for remote management, and it was not liking running in a container. It would have problems sending and receiving the out the hundreds of gcode and gcode responses per second AND running a web server at the same time.

Am I remembering wrong or didn't sometime in the last year a like GUI wizard come out that would write your Raspbian image to an SD card while also allowing you to specify all the standard setup stuff like your wifi, SSH config/keys, etc.? If it did I cannot remember the name or a keyword to find it.

You can select all those options in the default Pi Imager by pressing Ctrl-Shift-X, which they keep hidden for some reason

So hey, a while back I picked up a Raspberry Pi 4 and turned it into an emulation machine. I picked Lakka as my frontend and I've been pretty happy with it.

Cut to this last weekend, I decided I wanted to try out Steam Link between my PC and my Pi. Unfortunately near as I can tell that isn't something that Lakka can do; or at least, it's not something my build of Lakka can do and my build (from ~Jan 2020) won't update via the GUI. So I'm curious what you guys would recommend? I'd like to stick with 1 card and 1 OS for both my emulation as well as my Steam link so it seems like the best solution is to load Retropie, but I'm always up to learning about other means or suggestions to get things going

I was enjoying Lakka when I tried it last year and I wish it had stable updates more than once every two years.

I just happened to trt lakka for the first time today on a pi4 8gb and while it is super easy and has a nice interface, the emulation of SNES and N64 was surprisingly slow. I feel like I'm missing one weird trick.

SNES games were much better when I changed from the default core but for N64 there are only two cores and one doesn't even run so .


This was with the 32bit development image so maybe I'll try the stable or 64 bit de build tomorrow.

But yes lakka doesn't have X so you cant do steam link

I like lakka too, but the stable release is pretty old now. I'd switch to Retropie to do what you want to do. I much prefer the clean retroarch interface and the fast booting from Lakka, but Retropie has a lot more updates including Steamlink.

Such graceful, delicate creatures.


I'm a fan of Batocera, it's a pretty easy setup and supports a good number of systems. It's got Steam Link via Moonlight, I haven't set it up on mine though. It uses Emulation Station as the frontend, but they've got a customized version that includes wifi setup and a bunch of other things.

If you're installing it to a bigger drive or SD card, you may need to format the data partition (it makes a 6GB partition for the OS, then roms, saves, settings, etc are stored on a partition on the rest of the card), but you can do that through the menu.
