super cheap video recorder

 

Anyone tried one of these (or similar):

I am tempted to get one. Around $8 to the US. I would just about double my investment putting a micro SD card in it. I would really like to find it as a component that cheap, but I haven't seen one. I guess I could rig a servo to press the power button and then the record button.

EDIT - After getting the feedback from pips and the link provided, I went ahead and bought one...

i bought one in the past. it works well, and the quality is fair. i would recommend this camera if you need a small spy camera.

this guy did a very detailed review, and continuously accumulates things about this type of camera: http://www.chucklohr.com/808/

you could avoid the servo and hack the contacts on the camera, by opening it up and soldering a relay or an optoisolator to the two button's terminals to trigger it with a microcontroller

 

Thanks for the link. This picture:

is somewhat encouraging, though I think it is bigger than actual size. I should be able to solder to those and the VIN on the other side.. Amazing at the circuitry they can sell so cheap. I will probably start by just figuring out a holder and starting video before I start the robot. 

I don't need a spy camera so much as something I am not too worried about placing at risk and that can be mounted high without affecting center of gravity much.

Just some very basline testing so far. It does a better job sitting in one spot recording things that are moving than it does recording while it is being moved, but sound and video quality is decent enough to be useful. I hope to do a recording with it on the AGV while doing GPS homing this weekend.

i also thought the same thing. but i will be building an rc plane and controlling it manually. still it is excellent for first person video. it has very rich color and a good framerate.

It will probably take some decent in flight video but if your is like mine, take off and landing are likely to be blurry. I wonder how well it would work with a well positioned LCD in the corner of the frame to output GPS location and bearing.
