I was looking for similar board, and probably the cmio3 + cm3 is best bet (approx $114 + $54 for cm3 ... approx $114 + $28 for cm3 lite). I think the cm3 lite has both camera slots (one 4 lane, one 2 lane), so might be cheaper option (mods can correct me on this). Only other alternative in range tha...

Are you saying you have no ISP-provided WiFi-to-internet router to make a connection from your Pi AP device? Are you needing public internet access for users of the AP, or is your local webpage all you need?

I've noticed that other people using utility voice narrow band FM are also using these in their command line:

Code: Select all

-s 12k
-l 70

12k sample rate for narrow band
70 squelch level

Have you played with the squelch level?

Regardless of the adapter you're using, the Pi can probably be made to work with it (and your monitor). You might need to use a custom configuration in your config.txt file. I used something like this when I had an hdmi-to-vga adapter: hdmi_drive=1 hdmi_ignore_edid=0xa5000080 hdmi_group=2 hdmi_mode=...

Have you done anything more with this? I've been looking for such a thing as what you describe for quite a while. The usual intrusion detection tools are very verbose and can deep-packet mine, but they're not very good at pattern matching or more intelligent observation of machine state. I even thou...

@jeanleflambeur thank you very much for detailed answer :) I also planned that maybe just for start and first tests I will grab some Access Point with bigger antennas and power it from my car, so it should work for higher range. @elmo180 Having said these, you might be better of with something like...

Hi @balanga (freebsd)! You won't need any routing, and you could do what you want to do without using HostAP (the airport connection), but it'd be very insecure in my non-expert opinion. It's better to use the access point method, IMO, and do it pretty much the way it's described in the referenced d...

Would this be using AI, or some other means of pattern analysis?

This thread is a little bit dated, and probably the author has already figured out how to do his setup. But, FWIW, when I've played with RSSI it's been my impression that the values are not always consistent for the same distance. It probably has to do with reflections and absorption, etc. I wonder ...

One thing that can never be said about old Opera or new Vivaldi users: and that's that they're not really big fans. For me, the new browser is "OK" - and I've noticed no significant problems in about two weeks of usage. Another nice thing is that the same Vivaldi build works just as well o...

It would be great to have some semi-permanent memory on board RasPi. A note of disagreement here. Having no non-volatile memory (modulo a small handful of OTP bits) is ideal for support and troubleshooting. It means that every machine is, prior to power-on, always in the same factory-fresh conditio...

Is this a real problem, in the sense that it HAPPENED? Or is it just theoretical speculation? Because there are many other usage scenarios for SD cards when power goes off after a write. For example a camera shutting down from a low battery condition, the user removing it from the computer, and so ...

Ronaldlees

Take a Pi B of some sort, issue the shutdown and then *watch* the lights to see what is happening and how long it takes. That's your delay time. Yeah - I've unmounted external (extra) SD based file systems on Pi boards, instinctively grabbed for the SD to pull it, and glimpsed that it still had tho...

Ronaldlees

I've seen a few numbers on the current consumption of uSD cards - and it seems to range from 5 - 40 mA. That isn't much power. So, it seems that one could put a pretty low capacity power source on the SD itself, and just leave it run after a power cut. Maybe it could be a rechargable bat, supercap, ...

May I suggest the free and open ogg123? It's very lightweight, and can be run easily against plain old ALSA with no extra layers, and best of all - it's built to use the free ogg vorbis format. apt-get install vorbis-tools Example run: nice -n4 ogg123 -d alsa -o dev:"hw:0" --audio-buffer 1...

Do you have a Pi 1,2, or 3? On the Pi3, you may need to make some config changes and/or compile gpsd from sources: https://www.raspberrypi.org/forums/viewtopic.php?t=138711 On the Pi2, I just install gpsd via apt-get. Works fine. Then you can use open street maps or one of several other programs to ...

It's a poor attempt at trolling. When the competition can't even troll properly you have to wonder how good they are at electronic design and engineering. I can't help but thinking the same thing, albeit the post could still be genuine, and somebody (perhaps not very tech oriented) - who is simply ...

One of my SBCs has both A15 and A7 cores. I'm confused by statements made about the A15 (the arm post implies they're not very worried about that core, even though it's on the list mentioned at the top of this thread), but I've turned those cores off just as a precaution. Seems to make negligible di...

So you were just generally searching for an editor, and found StrongEd. Maybe a fortuitous fork in the fence row for you! If you're looking to kill off the boredom bug, RiscOS could keep you entertained for awhile, and it's available for the Pi!

Ronaldlees

Welcome to the Forums! This sounds like an interesting project. I've done nothing like it myself. So long as what you are "moving" does not create a safety hazard, it seems like a unique, challenging little project. Do you want a robot arm to move based on voice commands? You probably shou...

I would be inclined to use the official Pi camera (even tho I don't have one yet) - because USB/UVC cameras are going to be slow on the Pi due to the USB bottleneck. I've tried using a USB webcam camera on a Pi2, without very exellent results. Maybe a low-res model could work better, but I'd think t...

Really?

I would consider that a plus, cuz I have some of the auto-eject sockets that only eject now.

This is what it means when net neutrality is not required. Your ISP can determine what sites and services you can access, and at what speed. Companies like Amazon can pay to ensure that they alone offer a decent user experience, effectively destroying all their competition at a stroke. And in areas...

Newer versions of the TP Link TL-WN722N (namely v2 and v2.1) do not support monitor mode out of the box. Right. I think that is because they switched from the Atheros chipset to something else (maybe RAlink or Realtek). But v1 has the Atheros AFAIK. The WN822N v1 had the AR9170 chipset, but it's th...

Probably the lower voltage on the 5V rail is more likely to cause issues with HDMI, if that's being used, than with some or even most USB stuff. Just guessing.
