Hey all I need a good micro video camera that is under 2" across. I'm planning on making a parachute round for my small grenade launcher, and want to put a camera on it. I thought I'd just buy a key chain cAmera because they're cheap, but I've been reading some reviews and they all are terrible. So does anyone have a keychain camera recommendation? I'd prefer to spend under 30 on this thanks all

I believe the ones he uses are around $60 but I could be wrong.

A helmet cam works well. They are built tough and have good video. Look for the ones used in model rockets.

Wow a zero second delay on the motor. Must have been a small parachute on that rocket...

Look at the motor used. 5 sec delay. You mistook air noise for engine burn.
C6-5 motor.

Yea your right, you can really hear it in the 2nd launch played back in slow motion. I like the camera he used, this video really shows how good it is.

If only one of these cameras would work on the MiniBoy projectile

You can get the camera small enough that's easy. It's the battery, antenna and transmitter that's the problem...

Yeah those issues, and acceleration forces, were my concern. I'm sure it could be possibly to gut a keychain camera and fit it inside MiniBoy.

The keychain cameras you see on ebay are generally referred to as '808 cameras', and there are a whole bunch of different versions. Some good, some bad.
I've only ever owned a #3 type camera, and it wasn't bad. It occasionally dropped frames (possibly a low-spec memory card) and the charging circuit in the #3 cam never did work properly. It would never cut off the charge, you'd have to unplug it after an hour or so. Not good considering it uses a LiPo battery.
However, the footage wasn't bad. However, it used a 640x480 pixel sensor and upscaled it to a larger, 720x480 avi. Note the differing aspect ratio, so video out of a #3 camera appears stretched. They generally sell for $20-$30 dollars.
The newest version at the moment is the #11 cam. I'm not sure whether it suffers from the charging problem or not, but the great thing about the #11 is that it records in 720p HD, and has a true 720p sensor... No upscaling or stretching. These ones go for about $40.

I found tying a bright pink, orange, or chartreuse mason line to a projectile provides very little drag and makes the landing easier to spot. The projectile can be buried in a bush and the 10 feet or so of the bright string draped over the bush makes them easy to spot. I've used this with bottles of water and a 10 to 20 foot (3-6 meter) string works well.

This isn't to find the landing spot, this is to create an aerial camera project of my own.
Thanks for the info on the 808 #3 camera, I did some research, found a seller on ebay that seems reliable (As reliable as hong kong sellers can be that is), gonna keep looking though while my paypal account gets approved.
