Desktop install -. I'm lost

I have an older Acer I'm attempting to install Pi Desktop on. Using the disc that came with MagPi a couple of months ago. I got it installed even though I had no idea what all the options were about (Graphical Install, Install with persistence, etc) After installing and starting up I had no track pa...

Pi camera power

Is the camera powered on at all times or only when called upon? The reason I ask is that I want to add a night camera to my chicken "RoboCoop.". Problem is that chickens see IR light. The illumination I would use would be the built in LEDs on a 3rd party NoIR cam. If the cam is always powered then t...

Re: Running a python script at startup

Are you sure the script isn't running after a reboot? After it boots you can check using ps aux | grep robocoop.py When I used the command only the grep process was shown, no surprise there, if it's running you'll have two entries. jimmy 1882 0.0 0.2 4276 1844 pts/1 S+ 22:03 0:00 grep robocoop.py A...

Re: Running a python script at startup

I'll assume the script runs from the command line, do you normally use sudo to start it? Are you sure the script isn't running after a reboot? Yes the script runs from the command line. It runs forever once started. Hence the need to start it at boot in case power is lost, etc. It will start again ...

Re: Running a python script at startup

Let's send some output to a file to see what's going on. sudo crontab -e @reboot /usr/bin/python /path/to/your/script.py >> /home/pi/robocoop.log 2>&1 That will send both std and error outputs to a log file. Reboot and look in the "robocoop.log" file in your home directory, what does it contain? I ...

Re: Running a python script at startup

There are several ways to run a script at boot. You could add it to crontab. I'll assume you're using Python2, and need "sudo" to run it from the command line, so we'll add it to roots crontab. sudo crontab -e Add this line at the bottom @reboot /usr/bin/python /path/to/your/script.py OK, that did ...

Running a python script at startup

Yes I am a noob to both the Pi and Linux but have become pretty well versed at Python. I created RoboCoop that automates nearly everything but putting the fresh eggs in my fridge. The problem is I cannot for the life of me figure out how to run the script on boot. I have read hundreds of forum posts...

Re: Assistance with making photobooth

On my Canon DSLR, If I connect an external shutter release then closing the first contact (focus) wakes the camera from sleep almost instantly and it will last a long time in sleep (weeks). If you anticipate lots of pictures being taken with flash that will be your battery limit. Both Canon and Nik...
