Re: Using DateTime as a file name with timelapse -tl

I'm next to useless when it comes to programming but here's what I did. It doesn't set a date on the filenames but instead creates a directory with the date and time and dumps the timelapse images into it. Makes it a little easier to sort through them at least. import time import os getthetime = tim...

Re: Official V4L2 driver

This is fantastic! I've now had Motion running at 2048x1152 for the last twelve hours straight. The ARM is sweating a bit, but I've overclocked to 900MHz and it's running at a very good 2fps (Motion's a bit of a pig).

Thank you all so much for the work you put into this!!!

I'm not familiar with noobs, but did you set a static IP address on either of your Pis?

If not, do you have a working DHCP server with available IP addresses on your network?

Re: image goes black after a couple of minutes

Totally expected as you've told Motion to capture YU12 images. With any of the raw pixel formats (YUV or RGB) the driver makes a guess as to what you're using it for based on resolution. If <= 1280x720, then it assumes it is video mode and effectively runs it as preview/video encode at whatever fra...

Re: pi noir behave like the regular camera board (indoor)?

It can be tough to tell under bright light.

One thing you can try is pointing the came...

Re: Power Question from a Newbie

Glad you got it working! You may also want to try a shorter cable, though - six feet is pretty long and those wires look quite thin. There's probably enough of a voltage drop over the cable to cause problems. If you plug anything into the other USB port, you may run into the same problem (even with ...

Turning down the quality didn't make much of a difference for me. Bumping the resolution down brought up the max framerate but didn't do much for the pausing.

I'm not sure if this is related, but it's possible you have a SD card that doesn't play well with the Pi. I bought some Kingston 4GB Class 4 cards and some SanDisk 4GB Class 4 cards. The Kingston cards are _achingly_ slow compared to the SanDisk cards. Running df or ls at the console can take one to...

I've noticed the same thing. I had a similar issue with Sheevaplugs a couple of years ago, although it was less of a delay on them.

Re: Internet Troubles

Right after it stops working, you may be able to get some information by typing:

Code: Select all

dmesg
or

Code: Select all

tail /var/log/syslog
or

Code: Select all

tail /var/log/messages
Those may give you an idea if something's happening to the Pi.

Re: Worked earlier...

How did you shut it down last? Did you pull the plug, or did you tell the Pi you wanted to shut it down first (either using sudo halt or sudo shutdown, etc)?

Have you changed anything since you last ran it - cables, power supply, SD card?

Re: Connecting the Power Backwards on the Pi

I don't know what's built in for reverse-polarity protection, but if I had to guess I'd say your Pi is toast. You could try letting it sit for a day or two before applying power again but since you're seeing a good voltage at TP1 and 2, something's probably blown.
