An $20 JPEG camera, an $4 RF module, Atmega and some batteries.
Yesterday i've put them together into a little radio-controlled time lapse camera, and wanted to see how long the batteries will last.
So, it was left staring out of the window from 2:50 to 20:30 taking about 1 frame each 30 seconds.
The result happened to illustrate the mood of a winter day in Moscow.
The camera itself:
On 4 AAs it runs for about 30 hours, on 4 AAAs - 12 hours.
This got me thinking - how about a camera for time-lapse photography, that would run from batteries for a few months (i.e. from a bunch of D cells)?
The idea is kind of to leave it be in a nice spot and come back next year, without worrying about getting power there.
This one seem to be quite inefficient on that front, having to transmit the frames, and thus keeping the camera module on all the time.
