One of my cameras will save the file on it's own but not when the charger is connected.

Also, this camera did fill a 4gb card on it's own. At the end of the third file it had a pulsating audible interference that gradually got louder towards the end.

Thanks. Sorry, I wasn't clear. After you recharge the camera with the emergency charger, could you again record two 20 minutes clips?

I think the answer should be yes (unless the emergency charger doesn't fully charge the camera). But then I don't understand why the camera stops at after three 20 min. clips with the emergency charger connected. I remember it just keeps recording until the card is full with the car charger.

Possibly the emergency charger charges the camera at a lower current than what the camera requires to record video? That could explain why the emergency charger extends the recording time by just one extra 20 min. clip. If the recharging time is longer than 40 - 50 minutes, then it's quite likely that this is the problem.

Interesting... seems these cameras all have a different mind of their own. If you filled a 4 GB card with just three files, yours is also recording at that much higher 10kbps rather than 7 kbps like mine did, producing 1.5GB 20 minute clips instead of 1.03GB clips.

That pulsating noise is what happens when the battery power is about shot. If your card was full, THAT WILL cause the file to be saved (I confirmed that on mine). But had the card not filled up and instead the battery was finally depleted, you might not have gotten that third clip saved.

I think I'm ready to stop trying to figure all this out since it varies from one camera to the next. As long as I can get two 20 minute clips, that's longer than I fly a plane on any given flight, so I'll have the full flight recorded except for the 3-4 seconds that is lost between clips.

He said the card did fill up, though. That could be why the recording stopped, even though the battery was also getting low from the sound artifact that was on the third clip. If his camera is one that shoots at 10kbps data rate with 1.5GB per 20 min. clip, the card will fill up before the third 20 min. has expired. The size of his three files would pretty much tell if the card filled up before the battery was dead.

I think you could be right about that. It would be a good test to do.

I agree. and you could get an e-charger and charge up in between flights if you wanted. I have been consumed with this and it really doesn't pertain to what I want to do with the camera. I need to check/adjust focus now. Then look into the whole editing, file conversion, and filters thing. I'm so far behind.

The card was full.

All but your last question is answered in post #2 and #3.

The best lens has not yet been found. The only lens available so far is the one that comes on it. You can view many videos here to see if it is to your liking.

Yes, it is. See Post #2 of this thread.

Yes it will work fine, but the battery will run out before you use even 4GB (see this post for more information).

Here's a quick comparison I did this morning as a storm was moving in... It's the Keychain camera, a JVC Picsio, and a Kodak Playsport. I think the keychain camera holds it's own quite well!

You can see the wider FOV on the keychain camera here too. Forgot to mention that in the video...

Playsport vs. Picsio vs. HD Keychain (2 min 48 sec)

I like the wider AOV for AV use. A little post processing to desaturate the color and tame the hot spot, plus a click less contrast and a touch of sharpening, and the HD key cam would compare even better! I've notice the color saturation really "blooms" as the light level increases. If we could just find a different lens that more evenly illuminates the CMOS array in the corners, I think a lot of the central "hot spot" would disappear.

I don't want to mount inverted and have to flip the video during post processing. No good reason that's just me

No problem turning on/off. Plastic box is soft enough to turn on/off. Also no problem for mounting under wing... Tom, no o-ring needed. Tested in all positions, never trigs by itself. Beside, it is ok if You put a small 2-3 mm dick foam between TIC TAC case and wing. No vibrations, at all.
Rick NR417 yesss, really is 20 metres amazing depth. Electric tape must be flexible (good quality brand) and voila null problemo for HD scuba... BUT, divers know that on 20 meter we have light problems... As I said 20 meters is testing depth only for Tictac solution.

Got mine today ordered from eletoponline365, charged the battery, tried a short video for testing and then tried to remove the date using the "date off" procedure. I copied the firmware to the root diectory of the SD card, with the same name, then tried to turn on, and wait for the yellow light... but it never turned on again. Something went wrong, no idea what happened, it should be a newer model I think (placed my order less than 2 weeks ago). I guess the camera is dead
