WiFi: IP address in the range169.254.3.x?

I set up WiFi (raspbian-jessie-lite) using the tutorial https://www.raspberrypi.org/documentation/configuration/wireless/wireless-cli.md. Everything OK, I just had some fears when I saw the IP address 169.254.3.34. Effectively, WinSCP cannot connect. I suppose the easiest way to solve the problem is...

Re: python error

Are you sure your program is a plain text file? It should have something like 16 bytes.

Re: Little Timelapse project

Two more suggestions:

1) Delete the picture if it is too dark
2) Move periodically the pictures somewhere else (if the Pi is powered during 19 days, there should be a way to connect it to a network)

Re: connecting usb webcam with pi2 without internet connecti

Depends where you put the braces.

(can we connect standard usb webcam to raspberry pi 2) and (record videos without using internet connection)

sudo apt-get install fswebcam

I prefer the Raspberry camera by far.

Re: Network share without password

Can you give more information about what to do with /samba/etc/smb.conf?

(WinSCP works fine, but it changes the date/time of moved files to the moment of the transfer; the DOS copy command works fine, but the DOS move command results in "Access is denied.")

Re: camera.annotate_text_size stopped working after upgrade

Sorry for the late answer, I have been away for some time. I cannot give a command line example - it is a Python script. I did not keep the original script and I cannot reproduce the mentioned problem as I do not remember the settings for the text size and background. However, I could reproduce an e...

Re: camera.annotate_text_size stopped working after upgrade

Thanks. It works perfectly in 2592×1944 mode. Strangely, in 1920×1080, only 10% of of the text appears. As I do not expect to use this mode, I do not care.

camera.annotate_text_size stopped working after upgrade

camera.annotate_text is usually placed in the sky and therefore indiscernible. I tried in a test program including: camera.annotate_background = picamera.Color('black') and Python did not like this line. I had the bad idea to sudo apt-get upgrade. The test script executed well, but the black rectang...

Re: run a command on start up

I followed a few guides, http://elinux.org/RPi_Debian_Auto_Login , and they all led to severe system failures in my case. It seemed very hazardous... As I hate passwords, the very first modification I made to Raspbian was the first guide. It works perfectly for 3 months now. Are you sure you did no...

Re: Camera: capturing in _any_ light

Remember this is a pretty cheap cellphone camera Well, in my opinion, it is a GREAT camera. At least compared to s****y chinese CARCAMs claming 1280 x 800 pixels... Look at the MagPi Special Issue SE-1. That may help you out. Thanks, it helped, but I would prefer not to save a 'bad' picture at all....

Re: Camera: capturing in _any_ light

In essential, example 4.7 from the link, that means I leave the settings to the camera. I suppose the algorithm (when on automatic) limits the aperture time. I am not really eager to to write my program that calculates the darkness of the picture and I fear learning how to adjust the time, the apert...

Camera: capturing in _any_ light

When taking pictures during several days, there are two problems: a) pictures taken in the late afternoon and in the early morning are underexposed b) pictures taken in the night are completely black (space is a concern). The tutorial ( http://picamera.readthedocs.org/en/latest/recipes1.html ) expla...

Re: Autostart python script

I found a solution on internet:

sudo nano /etc/profile
Add to the end of the file something like
. python /home/camera.py

The drawback is that it works only in the command mode. I have to rename camera.py if I want to execute startx.

Keyless login into root

Hi there... I am a DOS user since decades and I have quite a lot of troubles to switch to Raspbian. Python is quite new to me, too. I use the Raspberry with a camera in places where I am not willing to bring the keyboard and the display. After hours of searching Internet, I got some results: Avoid e...
