using a miniature Model #3 808 keychain spycam with 8GB microSD card
triggered by a PIR motion detector
and steered by Arduino chip.
After issuing signals to camera buttons, Arduino chip is put into power-down mode waiting for the next interrupt to come from the PIR detector. Power consumption in power down-mode is 0.4 mA from a single LiPo cell.
Please see detailed description in the pdf file.



































I am busy with the 808 time lapse setup.
I used a zenerdiode 2.2V and a 10K resistor connected to the output of the arduino. (twice) to get the 3.3V. (ok it is 2.8V)
Switching the 808 on and off works. But I can't get the mode button working. I noticed in your schematic that you use a different circuit for the mode button with a potmeter and a diode. Why is that?
Or was it just trial-and-error?
For taking a picture, it did not work for me directly from Arduino like you tell. Then I measured the voltage on the picture taking button, when it was pressed and it was smaller, ca 2V. I do not know why. So I used a potentiometer to trim Arduino output to the necessary voltage, And then it worked fine.
To be continued.
p.s. I am pretty sure I have a 808 type14.

First thing I need to do is open the camera case and solder the wires. I do have some Arduino's and finisihed a couple of project already including a timelapse systeem which my digital camera triggered with servo's.
I am going to check the schematic of the 808 to see where the buttons are connected. Maybe I find a better alternative than your potmeter, diode construction. Although, your way seems to be simple and effective as wel.An low on power consumtion,
