Yes, this is possible. I've done this before, it's an interestin solutiong. I have discussed this with waterwingz in his topic for Ultimate.lua. This link is where the conversation starts.
I pulled the script that I posted there - did not want to maintain two versions.  If anyone is interested,  I can repost.

Thank you waterwingz, very helpful if you can please post the version of ultimate that checks for usb input. (I understand it's not going to be  maintained.)

Thank you JvdP for the link. Finding info in various other threads is challenging at times.

After modifying your ultimate script so that it can check for usb message...
   Which ptp client do run on the computer?
   To send usb message for ultimate to stop, what commands/script do you run in the client?

Many thanks again for help, much appreciated!

PS: sorry if these q's belong elsewhere - could you please tell me which thread to go to?

You should obviously ask these in the thread of the script, to which I already posted a link in my previous post.

That does leave one that will be in plain view in a commercial daffodil field that has a public footpath through it.
That is the risky one.

It does not look too bad.
The camera is quite a long way from the footpath.
The only people who use the footpath are ramblers.

Oh, wow that view is amazing. Hoping to see some results in a few weeks!  :blink:

How did the daffodil time lapse go?

Earlier in this thread we discussed holding power button down for long duration. That can be useful when the power supply is controlled by an external timer.

I have posted a warning about my recent bad experience with hold-down power button here:

(put it in a new thread hoping that may be easier for anyone searching later)

How did the daffodil time lapse go?

Well ..............
After a relatively short time the felt rain canopy (held on by self-adhesive pcb holders) detached and fell over the lens.

I have nice images of felt.
I removed the canopy for the remaining shots and there are sufficient to make an interesting timelapse.
I will do that as soon as I can and post a link to somewhere here.

Not sure about YouTube hosting, the NSA will have access to my daffodil panorama, as they will if I post on DropBox .
Together with satellite images and other data they can determine my location and interest in daffodils  :)

[seriously, those who underestimate mass surveillance are condemning their children and grand children to a bleak future]

So long as the NSA don't start thinking "Daffodil Timelapse" is code for something nefarious, we should be OK.

Besides, a shared interest in daffodils is perfectly legal between consenting adults so far as I know.

As for the felt rain canopy, I think next time you might try conducing the experiment with a Yorkshire tweed flat cap. They've been keeping 't rain oot of  't eyes for hundreds of years. Just apply a little velcro here and there on the weatherproof box, and your good to go. :P

Its been a while since I last upgraded the (not so) Quick Weatherproof Camera Box, but in light of the spectacular sunsets and long days here in Scotland, I revisited the "dump it and retrieve it later" aspect of the box.

Up till now I have been content to dump the box, and retrieve it a short while later, but I started thinking about the problem of getting the camera to sleep for long periods and wake up at a particular time, day, month, year perhaps.

The alarm clock idea works, but you are limited to one wakeup per day, not ideal for timelapses, or sunsets which inconveniently take place at a different time every day, so with this in mind I thought I'd throw a micro-controller in to the mix.

The design goals were..

1) Easy to replicate, so it has to use easy to find parts.
2) Relatively inexpensive (if it bites the dust due to environmental problems, or someone nicks it, I don't want to have to explain the problem to my bank manager).
3) It must be low power (actually this is probably he most important aspect of the design, it should be possible to run it for weeks or even months in sleep mode).
4) It must be flexible, easily re-purposed for time lapses or sunsets or whatever other daft use I think of for it..

What I have so far is entirely made from "jelly bean" parts, and the BOM comes to under £10.
It consists of an Arduino Pro Mini clone, a nokia 5110 display, the 8205 dual mosfet, rtc module and a salvaged lipo from a laptop battery pack (any 18650 lipo would do, I just happen to have a stack of laptop salvaged ones).

I'll post some images and a quick video of it all on the breadboard shortly.

The low cost of it all is in part, down to taking a punt on the cheapest Chinese supplier of each component. So far none of them have let me down.

Coding so far allows me to work out sunrise and sunset times to within a few minutes based on my location (lat/long), and the date/time from the RTC. I am running everything completely out of spec. The whole show runs from the lipo, so my atmel is running at 16MHz on 3.3V, the "5V" nokia 5110 LCD likewise.

Everything seems to run perfectly well despite this, and I can get the standby power down to <250uA without much effort and no real optimization, theoretically it will go to 1uA...
