Re: Resize image for use on a smaller sd card

I found all the answers that involved gparted and stuff to be too much for me. My situation might have been a bit different to some others, but here goes. I set something up with DietPi - it fitted on a 2GB card and worked fine. DietPi will expand the filesystem if asked but does not pester you abou...

Re: udev rule for identical USB cameras

Thanks. I tried that. The problem is ..... The cameras that i am using each take TWO video[x] numbers on the same USB port. The first camera is video0 and video1. The second is video2 and video3 etc. I can take a picture using 0,2,4,6 but if I try 1,3,5 or 7 it tells me "no pallette available". So I...

Re: RPI B+, /dev/ttyUSBx names changes after reboot

The multiple-identical-USB-device problem I have a Rasperry Pi with four cameras. I take pix with fswebcam which identifies the cameras as /dev/video0 .. video3. I need a persistent ID identify a camera number so that (eg) video0 is always the same one. Unfortunately this doesn’t happen reliably – o...

udev rule for identical USB cameras

I have a Pi running a weather station and four identical cameras (look at nzfi.avmet.nz if interested). The cameras are /dev/video0, /dev/video1,/dev/video2,/dev/video3. They are identical right down to each having the same serial number. If I reboot the system, the allocation of cameras to video nu...

Re: Feedback pls: Remotely connect to your Raspberry Pi

I am running a weather station that uploads a report and 4 pix every 20 minutes. To be brutal about traffic I thought it would be nice to only have the modem connected when it was in use. There appears to be a finite amount of "idle" traffic on a ppp link and of course there is also some on the data...

I have set up a Pi with a keyboard, screen and USB 3G stick that is connected and doing nothing. Looks like that uses about 150kB/hr = 4 MB/day.

It would seem that the "do-nothing" "not looking" data volume is something like rx 400 kB/hr, tx 250 kb/hr. That's a total of 15 MB/day which is a bit much for what I do ... Unfortunately ..... FWIW I don't care about disk usage, CPU usage or any of the other goodies. I would settle for a sporadic (...

Re: Webcam images full white with fswebcam

The problem may be with the camera being unhappy with bright light outdoors. To check this out, get a Windoze machine and install Yawcam. Hook up the camera and point it outside. You may well find that it starts off all washed out, then adjusts itself to something reasonable. If it doesn't then ther...
