Increase the exposure (lighter) and/or decrease the contrast.

But without knowing what your scene was like, these may or may not help. There is a minimum light level below which nothing helps...

No visible solder bridges.

Right now, I can't think of anything else than fitting a new battery and measure the stand-by current. Any suggestions?


EDIT: Oh s***. I forgot to insert the memory card in the bad camera before trying above (loading the profile). I inserted the card and went about the firmware update for this one as well. But I must be getting tired; somewhere along the process, I must have pushed a wrong buttom. Now the camera is in a silly state, where it just flashes green rapidly for a sec or two, gives a very short red blink and then goes normal charging green again. I better stop for tonight...

thanks
OK, you've confirmed the battery is indeed incapable of powering the camera... it will shut down when the voltage drops to about 3.7V (+ or-). I hope that is a typo (.34V) and you really meant 3.4V. The battery protection circuit should stop all battery current when the voltage drops to just under 3V). If it's truly .34V, the battery is wasted... throw it away after shorting the terminals to make sure it is fully dead!. The current when recording is close to 300 mA.

You may just have a defective camera. In that case, contact your vendor for a replacement.

If the camera is not responding to any button presses, do a cold boot (disconnect the battery, wait 30 seconds, then reconnect and restart the camera.)

OK. Will try.

Here is another video from same day. FW 0.41 beta.

Does anyone have a flight video/ground recording of the video out?

Couple of weeks ago I had a misfortune with my #16 v1, I dropped it on the ground and forgot it there overnight. It was rainy, and the device is not working correctly. I dried it in an oven before turning it on.

After I power it on, the yellow light stays on for a moment and then red light flashes three times, and then the camera turns off. I have tried everything, resetting the camera, removing battery, flashing with firmware, nothing seems to work...

I already purchased a new v2 D-lens camera. Actually I prefer the picture quality and field of view of the old camera with 0.67x wide angle lens attached. The D-lens is a little bit too wide angle to my liking... Of course the new camera is more "convenient", because the lens is less bulky and more securely attached.

You didn't mention if you first tried charging the battery until the green LED goes out, or if that doesn't help, putting in a new fully charged battery. And finally, using the external car charger to power the camera to see if it works. Worth testing to rule out a wasted battery as being the problem.

I doubt battery is the problem, but I will try charging it again.

By the way the device doesn't even work as a flash drive when connected to USB. (Yellow led turns on, then red led flashes three times, then it goes back to charging mode.)

I have an interesting result to report.

I had set my camera to autorecord on startup, but I accidentally turned it on without noticing. The first time seems have to drained the battery completely. I checked the files and it produced the maximum amount of recording the battery could give, including a frame grab at the end. The frame grab is garbage (totally corrupted colours, just a mess of green, blue and red). This leads me to believe it generated it when it ran out of charge?

The second time, I started it but it only recorded for 20 seconds before creating a frame grab and turning off.

This leads me to believe that the TOPRAM microSD card I am using is not being flipped to write-protected when the battery dies.

I may try testing this later.

If I am correct, this is quite good. Thought I'd share it.

ive read post #1-#5 but aside from small reference to video out saw no details. did i miss something? and gui is not an option for me due to resource issues. i really need a low res (640) camera for fpv.

so my question is can video out on #16 v2 be enabled via txt file? any info on how? what is the default?

This sort of information is always interesting, but I believe your camera performs (almost) perfectly normally

The firmware monitors the voltage and notices when the internal battery reaches a critical level and will save the last video clip. There should never be a problem with a "flipped to write-protected" card when using the internal power.

I have lost 5 cards so far which have flipped to read only, but on each occasion I have been using external USB battery power. This leads me to believe the voltage drops too quickly for the firmware to react. All my cards were new-generation Sandisk. I have never had problems with other cards, but have to admit that I am now being much more careful that my external power isn't suddenly depleted. Luckily I can get a refund for the defective cards, but I won't be buying any more of these cards until Sandisk resolves the bug in their card's controller.

There's no problem if you suddenly disconnect the external power because the internal battery will take over. As long as the internal battery isn't also depleted, your card should never become damaged.

Occasionally I also get an extra garbage file when power runs out, but it's very rare. Maybe it depends on the state of the battery, or even the type of card?

Tested with a brand new samsung 4gb class 4 card, same result.
3 files with almost the same size: 15 Mb.

The strange thing is that when I disconnect the camera from USB the green led stay on, I must push the power button to switch it off.

Well, you must be using a very old PC if you have resource issues with the GUI

But, yes, of course you can do it the hard way and edit the SYSCFG.TXT file by hand. Post #4 shows an example, but later firmware versions have a lot more options.

The file is generated as follows.
1. Make sure the camera's battery is fully charged.
2. Disconnect the camera and wait until it turns off.
3. Press the SHUTTER button and keep it pressed.
4. Press the POWER button and keep it pressed.
5. Wait at least 10 seconds until all the LEDs are OFF.
6. Now release both buttons.

You may now connect the camera and edit the file.

The file is saved back into the camera by exactly the same method. When the firmware has loaded the parameters it will delete the file.

The default setting is video-out disabled.

Here's the default contents of firmware v0.41.

Code:

Sounds as if it could be a battery or battery charging problem, but something is VERY fishy here. The green LED cannot be controlled by the power switch!!!!! Are you 100% sure you have a #16?

If the green LED stays on it means the battery is charging. Have you tried recording while the camera is connected to an external USB power supply (not your PC)?

If you don't have an external power supply, start your recording and then connect the camera to your PC. You'll have to be quick and make the connection before the camera turns off!
