19.12.2014 - Open-source one year time lapse camera
Sensor: 640x480 UART camera module.
Sample video: https://www.youtube.com/watch?v=aYzQma_5TN0.
RTC (DS1338) included, with CR2032 battery backup.
Stores images on a microSD card, which also holds the config file.
Power is supplied from 4.8+ V, over a 3.3V LDO, so 4 alkalines is ideal. I thought of using a switching regulator to increase efficiency, but it just isn't worth it on this scale - at best you can get 20% increase in run time.
One frame takes:
3 seconds at 100mA for the camera to stabilize and get a picture.
7 seconds at 60mA to write the picture down.
Between frames it stays in deep sleep, consuming 91 uA.
In other words, it uses 3.5-4 joules per picture.
On 4 D cells that would be around 50000 frames - at one frame every 10 minutes it will run for a year, at one per minute - for a month.
The intent is to set it and leave it be, coming back once a year - i like making long time lapse videos.
You can get the schematics and layout here:

I'm still thinking on what sort of an enclosure to make for it. 3D printing is not going to cut it here. :)

Hey Nelson, you `have been trying` and yet want `exactly the parts used`. That doesn`t sound like trying but rather cloning aka mass production clone attempt.
I wouldn`t see any reason as to why you would need the exact parts provided if you really would have tried that yourself.

I have been trying to do the same thing that your doing for a while now can you please provide exactly the parts you use

It's on the download page since a while ago. I guess i should have mentioned it in some visible place.

Any news on when the firmware will be ready to download? I have a building project at work (a new school) that I'd like to film with a year long time lapse...

Certainly, once i'm sure it is working reliably.
23.12.2014 12:35 - Artlav |
will you make the code available?
23.12.2014 03:26 - erik |
That would be "Ether" from Youtube audio library.

Cool project -- whats the music on the Moscow time-lapse? Fits very well with the video.
