If you went to the bother to rewire it, it might be easier to just make your own box out of scrap, eh?

The above is completely wrong. It is a USB power supply that has to provide 5V power so it has a regulator. It might not be 10400mah but it will definitely be a lot more than 2600mah whether they are in series or parallel. To me they look parallel but who knows.

Disregard this whole post!

Itīs most definitely wired in series. The 18650 LiOn cells are 1,2 V and since USB is 5 V you need to connect the cells in series: 1.2V X 4=4.8V. The regulator probably step the voltage up .2V and also keep the voltage up until the cells are completely empty since the voltage normally drops with usage.

The capacity is depending of the LiOn, if they are say 1500 mAh each the pack will also have 1500 mAh. If you want 4 X 1500 mAh (5000 mAh) you connect the cells in parallel but then you would only have 1.2V.

Easiest way to get more capacity would in my opinion be to splice in a battery connector between the camera and the battery pack. This way you can have several batteries and as high mAh as you want!

It's clearly made for AA batteries when it doesn't state such ANYWHERE in the link? Are you sure you are looking at the same ebay auction that was linked? It even states in the TITLE that it is for 18650 batteries.

This one is wired parallel. LION is 3.7-4.2v. If cells are 2500ma X 4=10000ma.

Here is one wired 2 cell in series X 2 parallel.

LION's are 3.7-4.2v

Pack is parallel wired, so it stays 3.7-4.2v, and you add up all mah of batteries.

Has DC-DC booster to take it up to 5v for usb out connector.


Link to second one I showed takes 9v input to charge, which is right for the 2 paralleled cells.

I actually order 1 of each to test them out.


Anyone know of a software program that monitors usb power, (volts-amps) and displays onscreen?

Would be nice to monitor usb when charging all my keycams, watching volt/amp trends especially at cutoff.

The only way of monitoring the camera battery voltage/current is to cut in to the camera battery wire with something like the Eagletree charger monitor, and even that will be affected by the protection circuit fitted INSIDE the battery itself.
Monitoring the 'USB' voltage and current will not tell you what is happening because there is a Lipo (lion) charge controller chip on the camera PCB.
To emulate a USB supply, the power supply should give 5v, but the lions only give 3-4.2 volts, so there is a step up circuit with unknown regulation characteristics - nightmare scenario time as we don't know how much current the camera itself is using - internal clock is always 'on' , and what mode is the camera in?

(there is movement from side to side because of me using my legs to pedal but you need a very large mount to get that movement out of the movie)

Empeabee,

The easiest way to emulate a USB power supply is with one of these:

1.5V to 5V USB Power Inverter

Even though it says 1.5V, it will actually take anywhere from 1.2V to 4.5V DC and provide a stable 5V DC at 300mA (up to 0.5A max) to a USB port.

Jaybee!

You've got to be kidding! $5 for just the mount? They'll be crazy to sell it at that price. Keep in mind we know the camera is (let's say) $40. That leaves $80 for the mount.

If you downloaded the either of these two folders prior to this date, please down load these two folders again so they contain the correct firmware files.

5/20/2011 UPDATE:

New Release 2 firmware NOW AVAILABLE.

The firmware we have been using up until today (Release 1) is now considered obsolete and is replaced with Release 2 Firmware (attached below). I have removed Release 1 from download availability here to avoid confusion and future problems. If you are still running Release 1 and need one of the old firmware files from that series, PM me.

The new firmware IS NOT INTERCHANGABLE with the prior Release 1 firmware, so do not try it. YOU CAN overwrite the old Release 1 firmware with the new Release 2, but you cannot do the opposite. Release 1 will load over Release 2 and run, but strange things can result, like the video frame size might be reduced down to a very high resolution 320 x 240 size like it did on my camera. Fortunately re-installing Release 2 will restore normal operation, and Release 2 has all the functionality of Release 1, plus it has added better color saturation control. So there is no reason to not install Release 2 unless there is something about Release 1 you can't part with.

Release 2 has just three firmware files:

1. Remove Time: Erases the visible time/date stamp from the video. Recording will stop/save/continue at 20 minute intervals

2. Continuous Recording & Remove Time: This is suppose to remove the time stamp and enable recording to continue without stopping until the flash memory card is full or the 4GB file size limit of the FAT32 file system is reached. With the latter, the recording will stop, saving the file to the flash card. It is suppose to then continue with a new 4GB file, but this part is currently non-functional. It will be fixed soon to continue with a new recording with only a several second delay.

3. Recover Time: Restores the time/data stamp on the video and the 20 min. stop/save/continue recording function.

All firmware has the improved exposure control from Release 1, and adds improved color saturation control. Any further improvements will be only be added to Release 2 firmware. The firmware is installed exactly like the prior ones. The following self-extracting zipped archives contain each of the firmware files in their own folders for identifcation since they are all named the same like the prior firmware:
Hi Tom
I feel that I've got to write to you to thank you for the above info, I've now done 2 of my #11 key cams and it worked perfectly both times, I only wish somebody could come up with the same type of file to do the same to my #8 cameras, as the #11 was so easy to do.
many thanks
Ray Kyte.
PS I hope somebody soon comes up with the updated file so that the camera will restart after 4gb.

If I connect the camera to USB it stay 2 minutes with the led red and after that all is off.There are not any kind of sign of live.
It mean s that I have to forget the Keycam?
I follow the instruction, put the firmware inside the SD card with the SDreader,put the sd inside the camera, switch on the camera but nothing happen and nothing on and now this is the condition.
Whta Can I do?

On the subject of mounts, has anyone made a waterproof case for these? I think I read about using a tic-tac case, will that do?

TicTac fits very well, the bigger box even when an angled USB connector is plugged in. However....... the video suffers from a lot of 'fog' in Dutch: it is 'condens'

TicTac behuizing en condens (0 min 45 sec)


First part is when I just left work. Some water gets on the class which I glued over the hole I made in the TicTac box in front of the lens.
Later on visability is good but the camera sees nearly nothing.

Same rout, different moments but with even more problems:

Compilatie Creatieve weggebruikers (1 min 43 sec)


Perhaps I can try 'anti-fog' like stuff you put on the inside of visors of motorcycle helmets.

pictures of my tic-tac boxes in:
http://velomobielfan.blogspot.com/20...ger-maken.html

pictures are without the glass in front of the lens. I attached it later on. I used a piece of glass you use for microscopes; the rectangular glass you put the thing on you want to examen (objectglas in dutch); the bigger one in the photo below:

I prefer just the camera housing. However, the camera housing isn't exactly water tight. So in (heavy) rain I like to keep the camera dry AND working.

That reminds me. I'd forgot about the project.. those videos were shot thru a small plastic bag..and were a little fuzzy, but I really want to try the u/w baggies I made with a glass lens cut from a microscope slide.. soon as get the courage and can test one or two with an No3 That pond has almost no sea life in it at all..so I am looking for a better place to shoot it too..

So that's the name: microscope slide

I wonder if you also experience 'foggy' videos. Another possible solution came to me: use silicagel or silica pebbles

I've posted in the FAQs all the things that have been done to get a non-functional camera working. Have you tried to flash in new (Release 2) firmware again. Will the camera do that when you turn it on and push the power button (sounds like ii won't). If that's the case and you have tried the battery total disconnect/reconnect trick, and still nothing, then I'd suggest you contact your eBay seller and ask for a replacement. You'll need to send the old one back to do that.

Holder


Made mine out of aluminum.
See post below for pic,s and video.
I put velcro on the bottom of the mount, didn't want velcro on the camera.
Might use it as, oh I don't know..... A SPY CAMERA.

Two of my #11 cameras are now down to about 15 minutes recording time, and one degraded very rapidly to about 2 minutes, so I have ordered replacement batteries from hxelepro@gmail.com. Does anyone know if these replacement batteries have the little charging circuit board attached, or do you need to reuse the old one? (Since I don't really have the equipment or the eyes for working on such tiny boards, I'm hoping I can just cut the wires and splice in the new batteries.)

They are the same as the originals, including the circuit board and red and black wires. I received my two spare batteries just this week, from the same vendor.

Different interpretation of continuous recording


This is my first post, and I would like to thank Tom for his great work in providing firmwares to customize 808 #11 camera.

In terms of the features in the firmware, I am most curious about the continuous recording. In the description of firmware post, it seems to imply that instead of chopping up the file at 1Gb size, it will record up to 4Gb, and so on, until the memory card is full.

In my mind, the continuous recording is more like you can keep recording the files in 1Gb size, but once it depletes memory, it will simply delete the oldest video and start a new recording there. That way, if we are on a long road trip (assume we use it as a driving recorder), we don't have to keep taking out the memory card after awhile (i.e. 80 min for a 4Gb card).

So as a feature request, is it possible to have some type of continuous recording even after memory is full?

Thanks a bunch!

I had a problem with my camera today. I turned on the camera and the yellow light came on. I pushed the record button and the yellow light went off. I launched my Radian Pro, flew for 15 min or so and landed. I stopped the recording and the yellow light came on as usual. I turned off the camera and went home. When I viewed the recording only the last minute or so recorded. Anybody have an idea as to what happened?

Hi all, thanks for all the information posted!
I was wondering if you could help though. I have a #11 and have found video appears a little dark, unless the sky is quite bright. This wasn't the case with my old #3. Would the new firmware improve this? Also, I know there can be no guarantees but I was also wondering if anyone knew how likely my camera would be to accept the new firmware. Perhaps someone has purchased the same item?
It was listed as HD DV LENS Video Camera DVR Flying Camcorder 720P #11, the seller was eletoponline365 and I ordered it in may 2011.
Many thanks!

I found it easier to unwrap the tape around the old/new batteries at the end, and unsolder/solder the wires already attached to the camera to the small circuit board from/to the battery circuit boards. There more room to maneuver and no need to cut, strip, heat shrink two splices in the wires.

Welcome to the thread. It might be possible and has been brought up here before. It's something that is only useful for certain applications, though, since many (me included) don't want to risk losing an earlier recording on the card for the applications we use this camera for (i.e. aerial video from RC planes). I've only been pushing in this thread for basic improvements in the video quality and fixing the existing continuous recording bug since that impacts the most users. But you can pass on other feature requests via the eBay sellers who work closely with the developer. More input from those paths may get more attention.

One interim solution is to use a larger memory card, e.g. 32GB card would give close to 10 hours of video... a long day on the road!

You may have a portion of the file corrupted to prevent display of some of the video. What is the file size of that 15 min. clip? Do you get just one min. of playback or 14 min. of nothing (sound?), then one min. of video at the end? Also, what program are you using to play back the video? The freeware VLC player will sometimes play video that other programs will not.

The #11 is radically different from all the other "808" cameras, hence this special thread for it. Your questions are answered in the FAQs link in post #3. Always go there first when questions come up. Your camera should accept the new Release 2 firmware just fine, but you probably already have one of that release installed, and I don't think you'll see any difference. You can always jack up the brightness during post-processing with an editor.

If you posted an example video we could see better if your camera is normal or not.

FWIW, a different way to get simulated "timelapse" photography is by shooting regular video, then editing it to play back at much higher frame rate. WLMM allows for a 64x speed up! The disadvantage is your recording time is much more limited, but the plus side is that the motion is very smooth!. When we get the promised continuous recording firmware patch, the 20 min. segments the cam now records won't be a factor, but even with those brief (3-4 Sec.) gaps at 64X playback speed it would likely not be very noticeable. The HD key cam with external power source and a 32 GB flash card could record for about 10 hours with the camera shooting at 6500 kbps video data rate.

Here's a sample 30 minute clip, played back in about 30 sec.:

http://www.vimeo.com/12528601
I am looking to do this. Does anyone know of software which can speed up the frame rate of an existing video file to create a time lapse movie? I do not have windows 7....only xp, so I do not have WLMM. I doesn't seem like it should be complex software. It could simply grab every 100th frame or so.

Thanks, Tom. One more question: I just tried to open a camera to take a look at those soldering pads (they look pretty small and close together in your photos), but the camera didn't seem to want to pop open easily, and it felt like it might break if I try to pry it open. Have you found a safe and easy procedure to open the cases?

That would give very jerky playback of faster moving items, like real TL video, but maybe that is what you want? Many editors (including some free ones) give the option of re-encoding the source video at accelerated frame rates, making much faster but also smooth video playback. AviDemux (free), for example, can out put the 30 fps native video at up to 199 fps, for a speed up of 6.6 times. And Vdub can go much faster, but you must first convert the video to .AVI format to load the video into it. And mute any sound before you do this if the editor doesn't do it for you.

Tom,

I took your suggestion and sent ebay seller the feature request.
On a related note, would you be interested to post a tutorial on how you modified the firmware? Is it entirely modified in raw assembly language or is there some type of decompiler to modify the firmware at your own will?

I am just wondering just how difficult it is to change firmware. I never wrote anything in assembly language. The closest thing I did was in C or C++, but always love to fiddle around to learn a thing or two. So any pointers from you are greatly appreciated!

Enjoy your weekend!

I did not modify any of the firmware, nor is it possible to do by hacking the .bin file. All the firmware revisions I have posted I got from the developer and/or my eBay vendor. So any changes must come from the developer as well, and being a small company and working on new cameras, they don't have much time to devote to our whims.

I do think they could fix the bug fairly easily in the Continuous Recording firmware, though, since the original Release 1 version already had that functional. Beyond that, getting the camera to hold it's white balance through different exposure levels is my first want, then diminishing the color saturatation a couple of notches so colors look more natural. After that, I'd be happy assuming they can't find a better lens to eliminate the edge vignetting.

OK... interesting. There's one more possibility that could do this, and maybe you can confirm based on what is in the 1 min. clip of yours.

If the camera battery were very low when you started to record, it could have captured the first minute then closed the file on low battery power. Then, with the recording stopped, the battery recovers a bit of voltage, and has enough power to light the LED when you push the button to stop the recording (but the recording had stopped 14 min. earlier on low voltage). If this were the case, your video would show the first minute of your recording, not the last minute. What does your recording show?

If that lens tube has a 7mm thread, it might fit in a #11 if the pitch is right! A bit of a pain to try it though. I've thought a wider angle lens could help fix the #11 vignetting, but I've not been able to find a source.

Also, the #11 has an IR filter on the rear element of the lens, not in the lens holder over the CMOS. So finding one with an IR filter adds to the problem.

It only shows the last minute of flight. The battery was fully charged when I started. I later filmed several short clips and a longer 15 minute clip at home and there was no problem. Previous to the flight in question, I had deleted several files from the 8Gb card. I don't know if this would cause a problem with recording. Also one other file would not play because of a corrupted part of the file, but it would not play any of the file. I just can't figure out how it started recording the end of the flight and none of the beginning.

OK... so it's an intermittant problem. Deleting files from the card should not affect anything. It sounds like perhaps the card memory space is corrupted. Have you checked your memory card's integrity or tried a different card?

Try re-formatting your flash memory card using the SDformatter utility, then testing the memory using the H2testw utility. Both are free downloads (Google for download sites). Once you have confirmed the memory card is good and it still does this with different cards, it must be some problem with the camera circuitry. But I'd try reflashing in the firmware as a last resort. I'd ask for a replacement if you can't get it resolved.

My important file got broken. After normal recoding, I connected the micro sd card with a card reader. My windows 7 shows the summary of the card "2.45GB free of 3.67GB", but no video file in the folder at all. This is the first time happen to me. I use 2nd version of the date-remove & continuous firmware. The video was taken for about 15 minutes after full charge. Class4 micro SD card was formatted right before taken the video.
Is there any known procedure to get the video file out of my card?

The used space on the card looks about right for a 15 min. video, so the file may just not have been properly closed for some reason. You can try to use a file recovery utility... a number of free ones available on the internet. I use one called "recova" (Google for a download site) which works very well for deleted files. But I have not needed to use it for files which may have not been properly closed for some reason. If you try it and it works, please post back here. Good luck!

I'm demo'ing a video editor which has the ability of making time lapse out of regular video. I took a 1.5 hour drive from yesterday and compressed it to 8 minutes (1000%) at excellent quality. Reads and saves lots of different formats.
It's not free, but I think I may get it. It's VideoPad. Found it at CNet. Corel has one that will also compress, but no try before buy, so I walked.

I recently used VideoPad for it's two week trial period. It has some nice easy to use features, but there's better editors for the money. After two weeks, the free trial just eliminates use of third party filters, and limits the output format to .AVI and .WMV/ASF formats. All other functions are intact, so there is no need to purchase this program if your conversion just uses the frame rate toggle when you output the file. The downside is you must also re-encode the video, which makes a slow editor excruciatingly slow!

Freeware like Vdub can do this conversion by direct copying the original video with no re-encoding, so the conversion is done in just a matter of seconds rather than hours (unless you found a different way to do this in Videopad). And you can convert the #11 .mov file to .avi (to import into Vdub) by direct copying in a matter of seconds using the MP4cam2AVI converter.

Unless you are also wanting to do some other editing with VideoPad that cannot be done with Vdub (like transitions and titles), these no advantage to using VideoPad, and a big disadvantage (speed) if you do. YMMV

Check the video editing links in teh FAQs (post #3) for more info on MPcam2AVI and Vdub.

I converted a native 20 min. #11 video from .mov to .avi using the MP4camtoAvi utility to get a lossless .AVI file (took 4 secs. to convert), then importing that into Vdub, and exporting with video set for "Direct Copy", NO audio, and frame rate set to 338 fps (to get the same speedup you referenced), which took 34 sec. So about 1 minute to produce that sped-up file even with the program changes.

The playback with WMP was jerky on my PC, which has a lot of memory and a fast video card, probably because the native h.264 video codec over taxed my system playing back at the fast rate. I did not have this problem when I converted an H.264 video to a .WMV file playing at 64x normal speed with a WLMM converted file!

<edit> WHOA! I rebooted my system because it was sluggish on several tasks I had running. Now after a reboot to clean up my system, that sped-up file plays back at full speed with no pauses whatsoever! <edit>

I took my camera out today after upgrading to continuous recording & remove time release 2. I had a 4gb card in and it only did 31 minutes at 1.54gb and then shut off.

Is there anything I can do to get it to keep recording? Should I change to the stop/save/continue one?

NO, the firmware would go until the 4GB files size is reached IF your camera had enough power. If you are using the "regular" #11 camera (not the jumbo with the larger internal battery), then your recording stopped because the internal battery was exhausted. The internal battery is only good for 30-40 minutes of recording. You need external battery power to record for longer periods. This information is in the camera specs and details in post #2... you did read that first didn't you?

Got your post edit. That sounds great. I will go back to the video editing faq post and....read it again!

Thanks again for the help!

But I have not needed to use it for files which may have not been properly closed for some reason. If you try it and it works, please post back here. Good luck!
No luck with the file recovery software including "Recuva". However, I am able to recover my video file using just plain "CHKDSK /F". It convert the whole folder into a file named "100MEDIA" without any extension. I manually adding ".MOV" extension so I can double click the video file to run in the players. Few seconds at the beginning of the video isn't viewable but at least I get most of it out. Thanks Tom for pointing me around this direction.

I am now able to charge with a standard USB charger and record at once with my V2 camera! Just a small hardware modification (one 0R resistor removal) was needed: http://www.penguin.cz/~utx/hardware/...e_modification

The current camera circuit switches to mass storage or webcam mode whenever power supply appears on pin 1 of the USB connector. I plan to do more experiments and change the circuit to switch to USB mass storage or webcam mode only if USB data lines are wired to a real USB host. It is not so elegant as firmware change, but my camera would be fully charged after car ride recording aswell.

After this first step my camera never switches to USB mass storage nor webcam modes.

I have been researching this little gadget and I would like to buy one to mount to my rc car and rc plane. If anyone knows where to get one that is a little bit cheaper than 40$ please pm me.
