Yes I would be interested. What stockmarkets can it download from?

Daveawalker

Or try smtp.mail.outlook.com ?

Ok we managed to get a faulty set up back..
Pi boots up leds show that.
But no hdmi output from Pi . Hdmi cable does not work and monitor does not detect hdmi with a working cable..
Power drawn by Pi3 is much higher than normal
Some serious spike ? or ??

On 1 site we have say 20 tvs all the same,only 1 floor has an issue. On that floor we have a different unit that is a logger with no tv and it does not have a problem, it has internet access for emailing and I can see it is not rebooting.. I get an email every time it reboots... If it were power the...

Daveawalker

Except that we presume that the issue is caused by HDMI spikes so how would leaving a TV off help.

Daveawalker

Except then you bring new power issues into the equation. I guess a complete spare system may be an option.. but how do we know if it's rebooted without the screen.. Site is 700km away..

Daveawalker

The problem is we have over 100 units out here and only 3 or 4 have problems and they are not at the same site. A site may have 10 units and 2 have issues. It is therefore not software! The original pis ie model A had protection diodes on the HDMI , we can t seem to find if the ModelA+ also have the...

We use lots of Model As 24/7 monitoring a nurse call system in hospitals. At some locations we have random sd card corruptions. Its really difficult to know if power goes down or not but suddenly the pis will show the boot screen. As they are running on the hospital ups there should not be spikes.. ...

Hi I have a system that was running fine on the last release . It uses the serial module in Python3 When I use minicom cpu usage stays fine. When I use my Python Script as soon as I open the serial port either /dev/ttyUSB0 or /dev/serial0 Cpu usage goes up to the 90% area and stays there .. cpu temp...

I have a 10000mAh power bank and what I have done is put in a buck DC - DC Convertor directly onto the Battery. http://www.communica.co.za/catalog/Details/P4138706545 This prevents the brown outs for me when power goes off, I am using it as a PSU. I have upped the voltage to 5.2V and it still drops ...

Daveawalker

This is a very important point.....
Try either of these (not both) in your config.txt file.
I had both, and it confused me I got coms when running a python script from the command line BUT it would not communicate when in autostart...

I will be using it.

Daveawalker

If you edit a file that does not belong to Pi you need to sudo.
I see older raspbians did have .local files for root

Daveawalker

I have just upgraded an SD card to 20-6-14 when i run sudo leafpad it tries to log changes, but does not have access to /root/.local/share/recently-used.xbel , as .local is in the home folder i guess its the sudo that is redirecting to root, the root folder is empty and the previous raspbians did no...

You need to add user to the dialout group

This is a simple copier, and only a small download
http://hddguru.com/software/HDD-Raw-Cop ... 0Setup.exe
It writes to smaller sd cards

Daveawalker

works on Python3 as well! Thanks

Daveawalker

This is a great idea! I would also like such a kernel

Daveawalker

Any chance of adding PPPOE configure, my router requires a login and password, so I cannot install anything until the PPPOE is configured.
