Keychain camera with PIR motion detector controlled by Arduino chip

Keychain camera with PIR motion detector controlled by Arduino chip
This project describes how to automatically take photos with 1024x768 pixel resolution
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 Have converted this code for use on an Attiny13 the smaller chip should take less power and can be installed "dead bug" style onto the 808 camera! I have not tested the code yet I only found this Instructable about an hour ago if it all goes well Then i may do my first Instructable detailing it!

Hello again,

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?

I am already experimenting. It is a good idea to use a diode for decoupling. It seems that the voltage on the wire when the button is not pressed matters. If I just put the 'mode' wire to 3.3 V and than let it loose, it's working. But attached to 0 Volt it does'n. I will try to use diodes and if that doesn't work I will use a transistor. And if that doesn't work I will use analogswitches (e.g. 74LS4066)

To be continued.

p.s. I am pretty sure I have a 808 type14.

I just bought 2 additional camera's. Via ebay I found out they only cost like 5 euro's. My 808 are of tyoe #14. Yesterday I soldered the 3 wires. Powerbutton, Modebutton and Ground. With a resitor and zenerdiode I am going to trigger the 808 from the Arduino with the 3.3V required. I also want to remove the battery from the 808 and use 1 powersource for the Arduino and 808.

Real nice project Well documented. I bought a 808 as well. I want to make a timelapse system which is small and cheap and your information is very usefull.
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,

BTW Do you really use the jig? Can you share some of your results and pictures? I am aware of the limited quality of the 808 pictures.
