Keychain 808 Spy Camera With PIR Motion Detector Controlled by Arduino Chip
Intro: Keychain 808 Spy 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.

Hi everyone,
One could also use https://kerberos.io/, it runs on the Raspberry Pi and it's also open source.

or you can use this to directly connect to your 11.7V battery; http://www.ebay.com/itm/3A-DC-DC-Converter-Adjusta...
just adjust the output to 3.7V and you should be good to go !!

just negative and positive are all you need, check out my post on this topic; https://www.instructables.com/id/usb-power-source-h...

i brought a key spy cam... but its not working.... i checked that if m connecting it to my laptop for charging the orange light is glowing..but its not getting on..shall i ve to change the battery???? which battery i should use sir??

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,

jpg quality is worse than the video quality.
Jpg is probaly 640 x 480. It is a pitty.
