Re: Google Hangouts with Raspberry Pi 4B - Request to Raspbian Foundation

Then where is the headphone jack? I don't mind paying extra to the foundation for something that works out of the box. Ummm.... it's right there, next to the HDMI connector. I guess you meant "Microphone jack". Yes, having a mic input would be great. The again, you would have to buy a microphone. R...

Re: Google Hangouts with Raspberry Pi 4B - Request to Raspbian Foundation

That's great, but I still feel the lack of microphone and drop in webcam is something the foundation could do to improve the idea that the PI is a desktop replacement. Well, to be fair, most desktops (not talking about those All-In-Ones, but the classic CPU tower + Monitor + Mouse + Keyboard) don't...

Re: Google Hangouts with Raspberry Pi 4B - Request to Raspbian Foundation

FWIW, I just tried my Pi4/4GB with a cheap USB microphone and the official camera with Hangouts. First time Chrome asked for permission to use both camra and microphone (which I granted) but it didn't work - no video, no audio from my side. I was able to receive video, though. I closed the call and ...

Re: Pi4A or "Pi3A++"

3A+/1G seems the easiest choice at the moment, but that's adding more to legacy gpio setups and firmware to have to support as time passes. but has that ram dropped enough in price and are the main users needing it, buying them. Slightly more complicated than that.... The Pi3 boards use (as I recal...

Re: Pi4A or "Pi3A++"

I''ve edited the original post to include the idea of USB-2 instead of USB on the virtual Pi4A. I'd have some trouble using a Pi4A with said characteristics on simple iot projects, that's why I'd like to have the updated Pi3A+. Of course, in that cases, the extra memory might not be needed, so if th...

So... now we have a top of the line Model (the Pi4) which starts with a 2GB model and can be a good desktop computer (ignoring some small non-issues some people like to complain about). This is great for countries like mine where money is more often than not a problem when it comes to access to comp...

Re: Small quiet fan for Labists case

About 2m away I got 35-40 db (and in that case I managed to make it "run smoothly"). Those numbers mean nothing since we don't know background noise levek in you room, or your phone's microphone sensitivity... Just to give some meaning, tell us the dB readings with the fan on and then the fan off. ...

Yes, but you don't see official statements with messages like "If you see a hammer on your kid's table, call us (the police) so we can keep him away from killing someone with it". A better way would be something like "Remember to teach your kids the safety procedures they should observe when handlin...

La opción mas simple es la de instalar MoodleBox:

Re: Pi Zero W as Bluetooth Dongle to inspect Bluetooth traffic

But I don't need to actually sniff packets off the air. The idea is to have the robot connect directly to the Pi, which would be acting as the Windows PC's bluetooth adapter. In reality this would be more like a MITM thing than actual sniffing.
