I think this gets done automagically but to be sure "sudo rpi-update"

It is unclear to me how the circuit is done. I want to be clear. It is most probably the series configuration where it does not matter which side it is on, but I cant tell the intent of the OP.

Code: Select all

3v3 --- resistor --- led --- gnd

or

Code: Select all

3v3  -+- led --- gnd
      |
    resistor --- gnd

Did you upgrade or download the image from this site? I ask because 2017-03-02 runs linux 4.4.50+ and I saw "[ 0.000000] Linux version 4.4.34+ ..." in your dmesg output. If you upgraded I request that you do the following (unless someone else has a better idea): sudo apt-get update sudo apt-get upgr...

BCM2708 Boot is the message the pi gives when it is trying to boot via USB (not a usb disk but usb off your pc). This setup is a little more advanced than a SD card with a suitable image on it. Mis information, please ignore. I read your statement as "I am unaware of this and kindly request that yo...

You may want to type "dmesg" and see if any errors related to this are shown.

Maybe post a little more info, like exactly what version of raspbian do you have?

I have a Raspberry Pi Zero that my wife gave to me as a gift . I have plugged it into my Windows 10 PC and all I see is an unknown device called BCM2708 Boot .. What should I do next ? I have searched google but cannot seem to find an answer thanks. BCM2708 Boot is the message the pi gives when it ...

The Raspberry Pi doesn't read from the RTC while it's running The Pi can if you tell it to. There's nothing in those links that indicate that the Raspberry Pi is doing any RTC access apart from at boot. I am unsure why "it can if you tell it to" was unclear. But since it was let me elaborate. hwclo...

You have a few components to make this work. 1. detect squelch break on the scanner 2. record the audio 3. form the email 4. send the email Squelch There are 2 basic ways to detect squelch status on the radio. The first would be to listen for silence vs non-silence. Depending on how quickly you can ...

Having some experience with this there is the standard and then there is what works. Some cheaper devices have shorter ranges on the same wire than others. The faster it goes the shorter the run as a general rule as well. So 10Mbps can do what 1000Mbps cant - especially with consumer grade equipment...

The Pi can if you tell it to. A kernel module is required to sync the hwclock and the swclock.

The point about clock skew is valid.

Hi, total newbie here! A student association I'm in is planning on building our own arcade machine to entertain fellow students during our pubs. I've got my hands on a Raspberry Pi 2 which is going to be the base, and as far as I've understood it's not that hard to set up something like RetroPie. H...

Maybe this thread is helpful?

Its from 2014 and some older code does need to be tweaked to make it run now because of other changes but meh it should at least give you a start.

That requires you have configured your DHCP and DNS servers to correctly map the new hostname to IP address. There is always bonjour which raspbian does by default (avahi). So the default raspberry.local can resolve even if there is never any DNS set up for the local zone. Bonjour is actually a nea...

In linux that would be easy. Simple shell script (even from a virtual machine) kpartx -a file.img mount /dev/mapper/loop0p1 /mnt # do whatever you have to do here # /dev/mapper/loop0p2 is the ext4 partition umount /mnt kpartx -d file.img dd if=file.img of=/dev/foo bs=4M Windows can be done with a po...

Got it running. I have been researching sensors, the passive Thermal Image sensors optimised for automobile use appear to be top of the heap and by far the most expensive. The sensors are subject to US export controls, not so much in China. ;) ITAR covers most night vision, which is silly consideri...

The reason a lot of small business do not have phone numbers is they cannot cope with the phone calls, it's time consuming if it's just you and maybe a helper. And it costs more, you have to have people paid to sit there and answer the phones. Their salaries, the floorspace they consume, electricit...

if you really really want to call them why dont you whois the domain? Of course its probably a mobile given the prefix and it may not even be active anymore. But really, I doubt that its going to do much given what is put in other posts. You might actually get more out of https://www.facebook.com/Th...

Thanks for the timer suggestion, I had thought about that, but still am not sure how to do it. off the cuff and without thinking too much about this: Change your PTT GPIO to a strobe/off. Connect that to a 555 timer that holds the relay open for lets say 2 seconds. You strobe/reset the timer every ...

wayne.dolesman

maybe they did not know the answer. http://www.instructables.com/id/Raspberry-Pi-for-Amateur-Radio-VOIP-Echolink/ Or you could write some network socket code (or just use ssh to execute commands remotely) to do it. Whatever you do add a timer on the end with the transmitter so you dont have an open ...

Thanks all for the feedback. Finding an excuse to buy a Raspberry Pi 3, priceless. Good call on the DTS Caddy parts, I will look into that. I kinda didnt make it clear so to be clear the DTS system is about 15 years old so cheap parts may be hit or miss. the CT6 is the current model with that and i...

cheap flir http://www.flir.com/flirone/products/?id=81752 plugs into the USB port of a samsung (android) phone so it probably wont be that difficult to get it to work with a pi using usb OTG. $199 (cheap is relative) Bit expensive but you can always just buy the kit for the Caddy Deville DTS, has a ...

oh ok. well glad its fixed.

That requires a frame of reference. In other words it depends on what you are comparing it to.

wayne.dolesman

Thought it might. It is because ifup is not managing the network interface.

Can you paste exactly what you have relating to usb0:0 from your interfaces file?
