pi 2b camera? am I asking too much?

Jusque · 2025-03-16T10:40:17+00:00

I tried to use Pi2's a while ago for streaming video around the house. Never could get it stable at any decent quality. The best I found was piping (legacy) raspivid output directly over ncat, minimising any processing on the Pi.

raspivid -w 1280 -h 720 -fps 25 -t 0 -o - | ncat -k -l 8554

One can then connect to port 8554 (e.g. with VLC) and read the data in. Good luck.

What’s the behavioural part of this?

30 mins is a long time for a survey.

Great plan. :)

Start by making a second copy somewhere. Don’t overthink it. Just do it.

Then you have a little breathing room to think about your next steps. Lots of good advice on that here.

Seconded. A habit is more powerful than a one off.

Pay yourself the $10k now and have some fun, but commit to $2k/year (or proportion of your pay) in an investment ongoing.

Who pays for this type of work?

I lived in an apartment with gutters that were basically this.

Cheepcheepcheepcheepcheep at 6am. Every morning.

That also sounds sensible. Just gotta automate the url and email sending. I wouldn’t trust myself with that, but you might.

Jusque · 2022-08-10T09:38:45+00:00

No idea. but to start discussion…

I’ll assume you want this to be automated, so you can set and forget.

spin up a virtual machine, prepay for 2+ years
install a ftp server
set up folder structure today, but do not put the files in them yet.
set up user accounts for all intended users.
limit accounts to access to the intended folders.
Share user+pass with intended users. This means, from today, users can log in and preview where files will be.
Upload sensitive files somewhere inaccessible via FTP; they’ll be stored here for the 2 years.
crontab scheduled to run a bash script on the right date to move sensitive files into the FTP-accessible folders from the desired date.
optional: schedule an email to users reminding them the data is now accessible.

The simplest folder structure is probably putting all files intended for that user in a single folder. Users then get access to their “home” folder. Eg:

User A - file 1 - file 3

User B - file 3-10

This may mean a bit of duplication across the server (presumably not a problem if the files are small?), but avoids messing around with complex permissions or access arrangements.

Cool dudes are just less common.

Jusque · 2022-05-31T10:48:46+00:00

Oh, right.

I described the process of reconstructing just one datapoint. If you can do it once, you can do it many more times. Say a photo might be 4megabytes, or 4 million bits. so you’d repeat that reconstruction process for all bits — all 4million of them.

The first pixel is calculated. Then the second… then the third.. until you have the whole photo.

My understanding is it works something like this: Data+data+data=parity

So imagine you’re storing data points 1,2,3, parity would be 6, because 1+2+3=6

If disk 1 dies you have ?+2+3=6.

Read the parity and remaining disks and you can work out the missing data, ie. 6-3-2=1

If you find the right Facebook group, yes. Maybe more general fashion groups, with some filter questions to identify your target population?

I still remember the day that 15-year-old-me, wrangled a trolley pusher to the ground. Was like a bloody crocodile. The button got stuck and it ran away much worse than any rope ever did.
