and then converted the resulting .JPGs into videos:

People bought lots of the Linksys routers back in the day.  They should be
out there.

I find myself avoiding wireless as much as possible.  If I can run a wire
to the Roku, security cam, raspberry pi doing what it does, the sprinkler
controller, the printer, I will.  No bandwidth contention,  no outdated
security, no dead spots.  I need to run power to the device anyways.

Some people might not be able to run network cables everywhere of course
and some devices (tablets) can't be wired.

Huh--the last time I had  a problem like that, it was exactly the opposite 
issue:
I go one that was meant for video chat and _did_ autofocus--continuously,
based on what it thought was the most interesting bodypart in the image
(I guess; I've heard that some of these things try to do face-detection and
 just fail miserably if they can't find *a hairline* or other
 popular facial features...).

Not-so-obviously..., it depends:

Some video cameras have frame exposure-times etc. that work fine (or even work 
*well*)
for video because of how noise and motion-blur generally are neuroprocessed
in moving images..., but then produce unsatisfying stills in the many situations
where motion-blur etc. are undesired.

Also the `rolling shutter' with CMOS sensors can easily lead to other awkward
visual distortions, e.g.:


https://en.wikipedia.org/wiki/Focal-plane_shutter#/media/File:Bundesarchiv_Bild_183-1991-1209-503,_Autorennen_im_Grunewald,_Berlin.jpg

YMMV--depends greatly on your subjects.

Does the camera show up as a regular video device? 
For a while I was using motion on a raspberry pi b with a webcam. Motion has a lot of options if you dont mind reading the docs and writing a text config.  It can  save images/video on movement and/or on a timer. It's also able to execute a script when an image is saved and has a basic web interface to view the cameras.  And its fast enough for slow hardware.

I'm not near my system to look at it, but OctoPI drives 3D printers and it has 
time-lapse camera recording.  I think it uses an external app to do that but 
it'll take the snapshots and assemble them into a movie.  You can also get a 
live feed via the network.

Hello all,
I'm looking into using a pine a64 running ubuntu mate to setup a time lapse 
photo using a standard digital camera controlled over USB. I haven't done a ton 
of research into it yet, but I wanted to see if anyone else has done something 
similar and had some advice/opinions. I was thinking of setting this up first 
as a way to capture an event going on, and second as a wildlife/security 
camera. 
I'm also thinking about using it as a wifi access point, the location that 
it'll be installed, a remote house in Maine, will have a dsl connection, but 
right now I don't have a wireless router, and since I have this handy I thought 
I'd take advantage.

I've been wanted to do some OpenCV projects, so I looked into
webcams. You can get 1080p for under $50 now. Plug and go in Debian
8. (I actually bought 720p for $30, but had to do it twice because the
first time I got one that was for video chat and didn't autofocus.)

Obviously you can use a video cam for snapshots too, so this might be a
good way to go. No need to worry about powering both the camera and the
Pine.

Well, I bought the Pinebook, and -- given its price, among other things 
-- seems like it would do a fine job using its webcam.  But if you want 
high quality stuff, I suppose a "real" camera is the way to fly, and not 
a webcam (be it part of a Pinebook or something external).

I set up my RasPi 3 as a WAP, and I have to say, it just didn't work 
that well -- egregiously slow, and low power to boot.  I guess the 
system is underpowered for the task, based on the reading I did.  I'd 
have to recommend using a stock WAP to make that happen -- bet you could 
find one for $15 on Craigslist or something.

Not everyone reads or even receives every message, in real time,
in the same order in which you saw or responded. So the custom Greg is
encouraging you to use is to provide a quotation of (the salient parts of)
whatever you're replying to *above your reply* so that the context
of your reply is obvious, even to someone who reads your message
without having seen any other messages in the thread first.

e.g.: some people will find this message as a result of a web-search,
some people just get thousands of e-mails a day and need to prioritize them
using some other system than `by the order in which they were sent';
many people will simply re-read messages at some point in the distant future,
when the memory of `the last thing that was posted before this' has
faded even _if_ it was once clear.

Also: you know how some people think Shakespeare is hard to read?
Try reading all of the dialog *back to front* ;)

"top posting" is "yoda dialog"
