Cause they put the high quality chips/controllers to them and only class 2 took the inferior ones.
The typical class 2 were above 2MB/s and up to 5MB/s
The typical class 4 were above 6MB/s and up to 9MB/s (some more)

Now that class 10 are widely available, and noone buys class 2, the class 4 are slower, usually at 4.8 to 5MB/s (based on H2testw results).
There is a speed difference at 4K write speed also.
...
What this shows is that the speed class rating only tells you the cards meet a minimum SEQUENTIAL write speed. Many cards are MUCH faster in that category than their speed class rating would suggest.

But, if conventional wisdom is correct, it's the RANDOM write speed that is the most important in shooting video (the 512K and lower rows), and the speed class rating tells us absolutely nothing about that! One of the slower class 4 cards (Sandisk) blows away the rest in that category!

Fortunately, with the #11 the video processor speed is not much of a bottleneck in the recording as it is with the old 808 cameras, so even the slower random write speeds these cards can produce are normally fast enough.

In a few words, yes!

I think class 4 got inferior chips/controllers and today is considered the lowest quality, as class 2 are almost out of production, or tend to be. Today`s class 4 are as fast as class 2 were in the past.
So there is no chance you find a fast class 4 as it was in the past.

Well, for a mobile phone or for a mp3 player (car or mobile), gps, and other devices that use the memory card for read only purposes then class 4 is OK.
As the read speed is good.
But for any other device or purpose that writing speed matters then class 6 should be considered the minimum.
Today I think I prefer class 6 over 10 as most devices I have are SD2.0 compliant than SD3.0. And although SD3.0 is backwards compatible with SD2.0 devices I have the impression that a SD2.0 card is better on such a device, but I may be well wrong as I have only one class 10 tested.

Well, the post was meant to be as a comparison to the class rating and its sequential speed, and about a quide of what to buy today, class 4 or better.
Mostly based on H2testw speed test, as it is more accurate and simulates the real world performance.
I did not uploaded the H2testw tests just because the CrystalDiskMark show some more info. There is some difference to the sequential speed between CrystalDiskMark and H2testw results, but it is the same percentage in every one, so it makes no big deal to the comparison.

As for the Sandisk and its good CrystalDiskMark 4K write speed.
They (the 4GB and the 8GB) were not any better than the slowest Toshiba 8GB or the slowest of the Kingston (the 8GB) on a #3. Lots of dropped frames when all the other have a good performance.
Neither formatted at 32K or 4K cluster size.
It was not any better on the #11 camera as well. But it did its job though. Not that the #11 was not happy with them. It is, but I did not liked them as I want a card not just for the #11 only.
So the difference is only present on CrystalDiskMark and nowhere else.

The bad thing is that sequential write speed matters when you select to use the card to any other purpose. As a usb flash disk using a card reader, or in a camera (I mean a photo camera) or any other.
So Sandisk were not so good to keep. I sold them already. So I sold Toshiba and want to sell this Kingston (or use it on my car mp3 player).

I'm left wondering if it is possible to change the framerate recorded by the camera to 25fps so that the problem is tackled at source?

Thanks for any help,

Hi Ian,

As to your question about changing the camera's frame rate, there is no way right now for a user to do this. I think the camera could be coaxed into doing this with a firmware toggle, but I doubt that will come to pass since most are viewing these on a PC and want the smoother motion that the 30 fps can provide. In fact, some would like to see 60 fps!

But, I'm curious how the video you posted compares to the the native clip as regards the ghosting you mention? How much better does it look? It looks to me like what you are seeing is more a function of the camera's shutter speed... it is too slow to capture the fast moving objects smoothly, and so is the frame rate for that matter. You can also see this "ghosting" in your clip where the car's forward speed is much slower going around a hairpin turn, but the fast panning of the camera makes trees in the distance look ghosted as they move rapidly across the frame.

The camera shutter speed is variable, controlled by the camera according to the light level. So the same scene in bright sunlight may look better than one shot on a darker overcast day. An extreme case of this can be easily seen by shooting a video inside at night, and seeing how any motion at all becomes very blurred for the same reason (not to mention the camera also drops some frames in that lighting and has some jerky movement from that).

Your conversion from 30 to 25 fps adds some artifacts of it's own if you are dropping frames to keep the same relative time frame and car speed.

The #3's biggest bottleneck is the speed of its video processor... it is so slow it does not give even fast cards enough time to consistently write the data before the next frame cycle is ready. I was not able to eliminate the dropped frames with my Transcend CL6 card on my #3 cameras... always have about 7%-10% dropped frames. Fortunately, the #11 does not have this problem except in very low light level (e.g. indoors at night with normal room lighting). Outside on even a very dark overcast day does not result in dropped frames, at least not with the CL6 Transcend cards I use.

My Transcend 4GB CL6 is also good. I would go for it again if I found it at a good price.
The good thing with microSD cards is that you can use them almost anywhere.
One product and you need no other. It can take place as a miniSD, SD, USB flash disk. So there is a job for it even if it does not do the job to the other any more, it is not wasted.

#11 808 V3 Supply Voltage Test

Here's a quick clip of the suppply voltage test I promised.

The 3.7v LiPo battery was disconnected for the purpose of the test.

The starting voltage was set at 3.9V (3,899V) and slowly reduced over a period of approximately 30 seconds with the camera recording.

To my suprise, all 35 clips were recorded successfully and written to the memory card (8GB class 6 Trancend), with no errors, despite the camera shutting down due to very low voltage conditions.

You will notice that clock noise starts at just over 3.7V - very faintly, but then increases substansially as the 3.6V point is reached. The camera finally calls it a day, letting out a final gasp at around 3.5V (3.45-3.55V) the average shutdown voltage from 35 tests.

The current consumption remained fairly constant throughout the tests, (it does fluctuate while recording) falling very slightly if anything towards the end, eliminating that fact a buck-boost voltage regulator is used.

Another few figures : the quiescent current consumpion of the camera (off) is 21uA - 21 microamps. The current consumption in standby mode is 140ma - The charging supply voltage is 4.10V at the battery terminals (battery disconected) with a USB supply volatage of 5.05V.

In the next couple of days I'll get around to uploading a video and discussing the audio problem and offer a solution to cure the LF distortion issue.

Richard,what firmware is in your camera? Continuous Recording or just Date Removal? Release 1 or Release 2?

For comparison, here's a clip I shot quite some time ago with Release 1 firmware with only the date removed. My camera would not save the second video when the battery died after the first 20 min. S/S/C clip. I captured this by manually timing when I thought the battery was dying, then plugged it into my PC USB port to manually stop and save the recording to see what the camera was doing before the battery died completely and lose the recording. As you can see, there was much breakup of video in addition to the buzzing we still get. The continuous recording firmware allows the video to go until the battery starts getting weak, but stops and saves the recording now before the video breakup begins. I get about 10 minutes of the buzz before the video stops and saves, with no video breakup. I wish there were a way to filter out the buzzing sound.

Hey, thanks for the test!
That explains why I couldn't get the camera to work using a 3.3V linear regulator instead of the battery. I thought the voltage may be too low, but I didn't know what was the lower threshold. I suppose 3.7V should be OK.

Did you measure the current consumption while recording? The adjustable SMD regulators I have are good up to 200 or 300 mA if I remember correctly.

I've had a search through this thread and can't seem to find it mentioned.
First of all, thanks to everyone who's looked at this and scratched their head over this one. I've now done a bit more research and moved my understanding forward a bit

First of all for YouTube I've found that they take a 30fps video without problem, so I won't even try to change the framerate when preparing a video for that platform. That should solve that problem.

That still leaves the frame interpolation when converting to PAL format. I've found an option on Sony Vegas (the video editing suite I'm using) around resampling, and turning it off seems to help considerably. The resampling blends adjacent frames together, which gives rise to the ghosting effect.

I've yet to look at the final output on DVD and I'll have to make a call on which one does look best when viewed on a TV.

@Tom - I hope the above covers your question as the raw footage shows no sign of the ghosting effect. I've just completed uploading a 30fs version of the same video, and as you can see the camera has behaved superbly

An increase to 50fps would also suite as frames can then be dropped directly - I think the problem really comes down to having firmware that is tailored to NTSC/PAL markets

Cadwell Park - fast lap in an RX8 R3 (2 min 6 sec)


@reptor - I would have thought that a slow card would result in dropped frames in the recorded video? I don't really notice this in the source video (using a class 6 card).

@120ccpm - I suspect that the 25fps videos that look good were recorded in 25fps originally. Not rotating the video doesn't help unfortunately, and I've got to do that anyway because the camera is actually mounted upside down.

@air_crash - I'll drop you a PM with a link to a video you can play with, about 6Mb and very high motion If you do get a chance then many thanks for taking the time out to help a stranger.

@RUDDERLESS - Thanks for the praise! Cadwell Park has become a home circuit for us and I've now been there 3 times. I'm starting to getting to grips with the techniques that are needed to keep the car on the track, but feel I have much to learn! I'm mainly working on improving the nut behind the wheel

Thanks again everyone for your help

I'd still be interested in a 25fps version of the firmware - if it falls within the grace of the powers that be.

Cheers,

Ian.

Nice video.

But now my story. My (supposedly V3 cam (since the red LED lights up when connected to the supplied adaptor, powered on pin 4) didn't stop buzzing and showing noise in the video when connected to my custom cable. This custom cable had normal USB on one side, an mini USB with 5 pins on the other side where I put a diode between pin 4 and the +5V cable, the 0V connected to pin 5.
The diode is to drop the standard USB voltage with 0,7V to get it somewhere between 4.3 and 4.5V. (again: red LED lights up)

But for some reason this cable doesn't work. When the same camera is connected to the same USB port but this time with another custom cable without the diode, so pin 4 of the mini USB connected directly to +5V of the USB port, the camera works fine.

BTW
My adaptor (supplied with the cam mentioned in this post) gives 4.61V. (when recording and also when it's off)

In other words: a custom cable with pin 4 connected to the + line, connected to standard USB port but voltage lowered by a diode isn't high enough. It seems to me the camera works fine on +5 V of USB, connected to pin 4

I've ordered another set of mini USB plugs to replace the ones I already have but have diodes in them. So my custom cables will be wit pin 4 directly to +5 of USB.

Dead lipo?

Firstly, sorry if this has been posted before. My #11 which was working perfectly doesn't appear to be charging correctly. The red charge light only comes on for about 10 seconds then nothing. I can leave connected for 45-60 min's and the case stays stone cold. I have tried a number of different leads with no joy. Any ideas?

Hoping for help

I have had no problem to date w/my #11 camera, until today. When reviewing my flight vid I noticed that after about 3:30mins the video went into a "slow-mo" type of recording & did so for the remaining 30mins of flight vid. Is this due to battery? Too much data in the card (had about 30 mins of other recording on card)? Card is a 4G class 6.

Thanks! Just looking for a little guidance.

Camera not Charging via USB

First of all I would like to thank everybody who has posted info on the 720p Camera 11# 808 and this is definitely the most useful & informative site re these type of cameras. I have recently purchased one of these cameras & it worked fine, recorded well, charged with the car charger, charged with the emergency charger & it also charged with the USB charger. As far as I can work out this was all until I just updated the time & date using the txt file template from this site. Since then it will no longer charge via the USB socket, I have searhed site as best I can for an answer & have tried numerous USB leads including the one supplied, various ports & three PC's, but everything else still works fine. Does anyone have any ideas / help please? (Not the "dont charge it via USB" kind of help) I've already worked that one out. Joking aside keep up the good work on this subject. Thanks.

Please ignore my ignorance on the Charging aspect

I always charge at home.. on PC USB and am used to the RED LED going out to tell me when it;s done charging.. But on the special Pin 4 miniUSB that is in the cigarette lighter cable and on other Pin 4 cables I have .. i never see the RED LED come on.. should I assume that the Lipo inside the cam can't charge unless the RED LED is coming ON initially?. I know these cables will keep the cam runing fine as long as they are connected and the external +5 vdc source is is Ok but can they actualluy charge the battery inside the cam even if it is recording just fine or is just sitting idle.. I am sorry .. but never used these to try to recharge like we do on a standard miniUSB so am not sure.. JimS

Nevermind the question on "does it charge when the RED LED remains OFF?" .. i went back and re-read the FAQ and Isoprops Link on the topic, lots of details Thanks!.. I see that the cam will charge the internal Lipo when using a pin 4 special cable even tho the RED Charge LED remains Off.. my only question now is .. ( and it relates to Post 4619 indirectly) is 1.) how can you tell when the cam is fully charged if using a special Pin 4 cable? and 2.) does the No 11 actually charge more slowly At Idle /OFF as suggested in Dee404's reply in 4621 below) when it's on one of these Cigarette Lighter or External +5vdc Lipo special Pin 4 cables.. ( and NOT recording)? anyone know for sure?

Jim,
On V1 and V2 cameras the red light won't come on when connected to the car charger supplied. I think it was tested earlier in the thread that the car charger supplied doesn't charge the battery much when the camera is in use and the camera uses the supply from the charger to operate rather than charge to full capacity of the battery and record.

Just tried refocusing my V3 and the lens thread seems to be held by something a lot stronger then the thread lock they use to use. Can't seem to get it to budge at all and I think I've scratched the lens when I slipped with the pliers

Has anyone else had any problems with focusing there V3?

Bricked or Nay?

Hey guys. Really hoping someone might be able to help me. I've tried searching in this thread for answers, but it's so massive, I couldn't go through all of it.

Here's the deal: Got my 808 #11 in the mail, tried to do my research, and found some pretty reliable info on how to take the date and time stamp off. Tried the firmware patch, and now the camera won't operate normally. After I tried it, the yellow light would just flash continuously and not do anything. So, I re-installed the ORIGINAL firmware, hoping that might help. The flashing stopped, but now the camera won't record video at all. It'll take photos, and apparently will work as a webcam as well ....but, when I try to record video, the light blinks off like it would be recording, but the device seems to freeze. It doesn't capture video, and I have to hold the power button down, then tap it to turn it back on.

Is it bricked? Did I just pay $40 to take crappy photos from now on? Or can one of you maybe help bring this thing back from the dead? I would REALLY REALLY appreciate any help bringing it back to life to record video again.

I'm not messing with any time/date stamp removal stuff again after this....

Thanks for any help you might be able to give!

It looks like you modified the case of the 808 to put the one ring that the lens connects to on the 808 itself. I've seen some others who did a tic-tac type box.

What is the recommended method?

Also how does the jelly wide angle lens compare in quality to this dealextreme 0.67?

Well, this is really odd. My perceived charging issues were a result of a series of recordings that ended prematurely with a buzz sound over the recorded sound that occurred every second or so. Then it didn't appear to charge - see above. Had another go at charging so I left the camera plugged in for an hour & again the red light went out after only 10 seconds. I then set the camera up pointing out into the garden to record the pouring rain and checked the footage. 35 min recorded without problems. Plugged in to USB and red light stayed on for a few minutes. Will run some more tests before trusting the cam with any important footage.

As a consequence, without external power the camera will only record about 35 seconds then stop.
I have this problem since flashing release 2 firmware, but this might be a coincidence. Too bad we cannot revert to release 1 to test.

I'm beginning to think the battery power problem with my V1 or V2 cam (rather suddenly recorded only 10 minutes) isn't a bad battery but may also be caused by V2 firmware.
Wrong custom cable doesn't seem the cause (which I also had in mind). So that leaves bad battery or firmwareproblem. With my cam it also occurred at about the moment I flashed firmware V2. But if that's the case, I'm rather lucky my cam still records several minutes instead of a few seconds.

Finally got out in some decent weather and record some new video with the HD keychain cam, both mounted on hat and also some onboard video.

Pretty happy with the overall quality of this cam. Wasn't too much contrast shifting even with a fairly bright day with white clouds rolling over at times.

Be sure to click though for 720P versions.

Well done, Giorg - an excellent and proffesional repair

Dee404's : your problem in removing the lens.

Remove the PCB from the camera housing and place 2 matchsticks on either side of the cmos camera - make sure the matchstick on the ribbon-cable side does not overlap the cable. Just so it sits on the black plastic casing.
I used 'blu tack', but you can use a spot of low-tack glue as well.
Position the camera in a vice as show in the picture - tighten it until it is held snuggly, no more ! - the lens serated surround should be proud of the top of the vice. Bend the microphone back towards the PCB if you need more clearance.

Pliers : look around for a small pair with a circular grip of around 6-7mm internal diameter - something that will mate nicely and securely with the lens surround ridges.

Position the pliers carefully and centrally around the lens and use a small side-to-side motion, until you hear a 'cracking' noise. At the time it sounds terminal, but it's just the thread-lock adhesive fracturing. Continue with the rocking motion until you get to a point where the lens can be full unscrewed.

Hope this helps !

Thanks, nice little guide that.

I was just using two pairs of pliers, the one on the lens screw slipped and has taken a chunk out the lens its self. I'll try and get a pic of it later.

On the cameras I had be for (V2) I picked of all the thread lock and managed to work the lens screw loose but on this one it seems well and truly stuck. I try it your way in the morning.

Good flying, but not very smart. Also, this is not a #11HD cam video (it does not have video out for FPV flying) and we would expect a CL10 to do no more or no less than a good CL6 or CL4 with the #11, so it is off topic. Please keep your videos posted here relative to the #11HD camera. Thanks.

Best Video Posting Site

Most videos posted here are hosted on YouTube. I'd like to suggest using Vimeo.com instead. Why you may ask?
  • YouTube does not display in full 1280x720 frame size, even when the "expand" button is clicked. When "full screen button" is clicked, the video is larger than 1280x720 pixels on a large monitor... too big, making the video look less detailed and blurry. With Vimeo, you still have those same options, but in full screen mode there is a button to "turn scaling off". Click that and the video is displayed in it's native 1280x720 frame size.
  • YouTube has too many users and not enough bandwidth (720p video is more prone to stalling and stuttering).
  • Vimeo has (arguably) better quality in their 1280x720 Flash Player re-encoding.
  • YouTube video cannot be download in the uploaded format. Vimeo allows your upload to be downloaded in it's original form for up to one week after uploading, but only if you toggle permission to do so. This allows others to download your clip to see it in the best quality, and to analyze the video to help troubleshoot quality problems.
  • Vimeo does not have the "music police" to trap and delete or replace recognizable music tracks you add to your video. But it's always proper to identify and give credit in your videos to any music you add, especially if it's not in the public domain.
Vimeo has a 500MB per week free upload limit, and only one HD upload per week will be rendered as a 1280x720 HD clip. You can upload more (up to the 500MB limit), but they will not be rendered in 720p resolution. There is a paid upgrade service available to bypass these limitations if desired.

<EDIT> This post gives a bit more detail on manipulating the toggles for the features mention above on Vimeo. <EDIT>

I think it is likely a coincidence, but you still can flash in the Release 1 firmware to check the charging function. The camera will still work, only the video frame size might be smaller than normal or have a different aspect ratio. You can flash back in Release 2 firmware to restore normal operation afterwards.

This is a working gimmick, extremely simple, no clock, no user input, just two clicks. I wrote this program to try and get the camera clock synchronized to the second, but I'm still having problems... I think the camera ignores the seconds. I've wasted too much time testing and have given up for the time being - maybe later...
There - you see why dev programmers hate Wouldn't It Be Nice If requests

I just got a #11 camera today from eletoponline365. I tried powering it up and no light. I plugged it into my usb for an hour and it had a red light on. When I unplugged it and tried to turn it on there was still no light again. Also when its plugged into my usb my pc is not recognizing any removable storage or anything. I tried holding the reset for a few seconds, but still nothing. I have a kingston 4gb class 4 SDHC card in it.

Did they just send me a broken camera? Or is there something I can do?

Audio Clipping Problem - Diagnosis and Solution

Hello all

This is a follow-up to post #4371 on page 292 addressing the problems many users have had with 'clipping' audio (sharp clicks and pops) when recording with the 808 #11.
It is caused due to variations in low-frequency air pressure, and is normally encountered in a moving car enviroment or caused by wind (in flight on a RC plane for example).

I'll split this into two posts, starting with a description of the nine pictures shown in the collage attached to this post.

1 This is a diagram of the electret microphone circuit, showing the biasing, decoupling and supply splitting arrangement.
You will notice the very high value of the microphone decoupling capacitor : 1.5uf (circled in red) - this is what we need to change.

2 A close-up of the PCB showing the location of the components depicted in the circuit diagram, figure 1.
These are outlined in the same colours for easy reference / identification.

3 A size comparision of the 1.5uf capacitor against a peppercorn and a grain of sugar.

4 Measuring the value of the audio decoupling capacitor using a digital capacitance meter - coming in at a huge 1.504uf.
This value is excessive in the extreme and will allow very low frequency and sub-sonic audio to be amplified and digitised, causing clipping.

5 & 6 The 1.5uf capacitor was removed and two single wire stands were seperated from an off-cut of hookup wire.
Holding the PVC sleeving, these were then soldered to points A and B (see figure 2), so I could test different values.

7 This shows a test capacitor soldered in place - in this instance, a 470nf was been 'auditioned'.

8 & 9 Showing the finally selected value of 220nf soldered in place on the PCB - plus the addition of a small jumper wire.
I decided to use a phsically larger capacitor than the original type, because I couldn't find one that small and even if I could find one, I wouldn't be able to solder it in place !

In the next post is a description of the test, the different capacitor values tested and the results, plus two videos - before and after.

All these tests below were performed using a 18Hz Sine Wave signal generator and 50W Subwoofer.
The position of the camera and volume level remained constant throughout each test.

1.0uf No real change - clipping still evident, perhaps not quite as severe.
470nf Good improvement - clipping present but much reduced.
220nf No noticable clipping.
100nf No clipping - starting to loose LF response.
47nf No clipping - little if no LF response - perfect for speech / dictation.
22nf Little midrange and no LF - tinny, 'transistor radio' quality.

So, I settled on 220nf - you could possibly get away with a 470nf, but this largely depends on the enviroment it would be used in.

The two audio clips - 18Hz Sine Wave / close proximity.

The first demonstrates the clipping using the original 1.5uf capacitor as factory fitted.

The second video uses a 220nf surface-mount ceramic capacitor.

#11 808 V3 - Original 1.5uf Audio Decoupling Capacitor - 18Hz Sine (0 min 32 sec)

#11 808 V3 - 220nf Audio Decoupling Capacitor - 18Hz Sine (0 min 18 sec)

Hello everyone, I have the V3 #11 with the firmware, "Continuous Recording & Remove Time". I'm using a Sandisk 16gb class 4 card. I'm using my camera on a motorcycle with the 12V plug. Red LED still lights up to indicate charging and the problem I'm having and I'm hoping someone here can help with, is once the camera records 4gb of film, it shuts off. I does not continue to record until card is full. Isn't the firmware suppose to record 4gb, save, then continue to record? Thank you for your time and help.

Dear Dr. 808 AudioSpecialist..
as newly appointed guru.. I must ask: will this mod help reduce the clipping I'm getting when standing in the wind, or talking too loud when shooting from under the Brim of a ball cap?.. if so, what would you charge to do it on a No 11 and replace the battery at the same time? where are you located?

Final question.. what is the impact on the audio clicks and beeps when you install this cap and the camera enters a low voltage threshold.. I'm assuming this Mic mod has no effect on that problem? correct? can you get some BEFORE /AFTER Video of the mod while flying it on a plane (ideally a slope glider?)?

The camera is recognized as a webcam when plugged in, can take photographs, but still seems to just freeze up when I try to take video. The light blinks as if it would be recording, but it doesn't, and I keep having to hold down the power button, then tap it repeatedly for it to come back on.

One thing I noticed ... when I power on the camera, it lights up, then the yellow light blinks off for a second, then stays on. Could it possibly be trying to reflash every time I turn it on? I've formatted the memory card since, and tried a brand new memory card, and still got the same thing.

Someone unfortunately removed the previous firmware from this site which is causing lots of confusion to people who have not read through all the posts in this thread to see why or who have discovered this camera somewhere else on the web and then came here. The firmware on this site is different from that on other sites. Try re-downloading from the link in post 3 and flashing that.

If you have a v1 or v2 #11, you have no indication of when the battery is fully charged when charging via the car charger or another external charger with the special plug, unless you are using the emergency charger accerssory, which has it's own charging LED. You can time the charge and go from that but that is not a positive indicator. I guess that's why the v3 was designed.

The use of the timeset.txt file should have no effect on the charging.

Xamindar, thank you VERY VERY much for the help! It worked like a charm and the camera is now back to full function and without date and time stamp! You have simultaneously lifted the malaise of feeling like I wasted $40 AND restored my faith in humanity! Again, thanks a ton. Appreciated muy bunches.

Final question.. what is the impact on the audio clicks and beeps when you install this cap and the camera enters a low voltage threshold.. I'm assuming this Mic mod has no effect on that problem? correct? can you get some BEFORE /AFTER Video of the mod while flying it on a plane (ideally a slope glider?)?
Reduce clipping when standing in the wind ? - YES, it will reduce clipping, if not eliminate it completely.

Talking too loudly / shouting - If you bawl into the mic, the sound will DISTORT and the sound level will LIMIT, but it shouldn't clip.

I'm in England, so not really an option, but would do if it was worth my while. I'm sure you there are others closer to you that could help.

The effect this mod has on low voltage 'threshold' microprocessor noise...
Sorry, it won't make any difference. This is not a mic / audio related issue, and is caused directly by the microprocessor / DSC clock.

Can I get some video before / after flying a plane ? - No, I don't have a plane but do have a car and can hold it out the window!

I removed the obsolete Release 1 firmware, because it is obsolete. And I posted a note in the FAQs page why it was removed. People don't need to read all the posts... they just need to follow the instructions in the title of this thread: "Answers to most questions in Post #1-#3". I can't help it if they don't take the time to do it!

I does not continue to record until card is full. Isn't the firmware suppose to record 4gb, save, then continue to record? Thank you for your time and help.

Time to break up the test gear and electron microscopes. Here are a couple of video from a hatcam HD #11 Keycam of turbine jets. The first had to belly land because the gear did not deploy (air leak). I edited it in Video Pad editor and deshaked before editing. The output is mpeg and the file size is very ly small because it doesn't make much of a difference with Youtube anyway. Video Pad also allows you to crop and zoom the "dots in the sky." Yes, it pixelates, but I don't care. For $40, it is quite the little camera.

The second is of a turbine ELAN that's real fast. Almost too fast (close to 200 mph) and I had to use slow motion to show one scene. It's really short.

Are you referring to this?
2. Continuous Recording & Remove Time: , and enables 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. The latter will save then continue recording.

This was all I could find and like I said, it doesn't continue to record after it saves a 4gb file size. Am I not reading it right? Thank you for your help.

http://www.rcgroups.com/forums/showp...postcount=3531

The part you quoted is there, and that is the way the firmware was supposed to work. But unfortunately, it does not and will be fixed. If you read the note under the firmware file icon where you download the file, it says the recording stops after the first 4GB file is saved. I guess I missed changing the description in the body of the post. I'll change it. Sorry for the confusion.

Yes... I was just getting clarification that the capacitor mod would not eliminate the wind noise altogether... some might have interpreted it that way. I mute or really diminish wind/motor noise in my aerial vids, so it's not a big issue for that use.

Bought 3 units of this camera last week and i've removed the stamp date from 2 of it. I thought already ruined both after 1 hour of struggling to turn it on. I have to cut the battery wire, disconnect and reconnect several time then only suddenly it turning on.

This is the worst firmware update method i've ever experienced. IMO, manufacturer must do something on this one.

Thanks to Tom for your "do not panic" words on your earlier post. It really help me. BTW, this camera is worth to buy.

I'm really surprised there seems to be many having trouble flashing in the firmware. I've done it dozens of times, both with original Release 1 firmware and new release 2 firmware, and have had smooth sailing. I have no idea what the difference might be other than pushing buttons too soon or something. Did you get the yellow LED turn on after flashing in the firmware? If not, did you first connect to the PC USB and turn on the camera? Are you using the Release 2 firmware from this thread?

I'm a newbie to these cameras but followed your directions to the "T" and it worked the first time, no problem at all.

I agree with Bill the Prof, too many shots of meters and oscilloscopes and stuff

Here's some excitement I had today starting at 3:25 of the vid. #11 keyfob video starts at 30 secs but I had to mix an fpv recording in at the start.

Read the description of the video for a little more info and watch full screen if you can.

I just received two new cams from one of the approved dealers on page 1. These are my 2nd and 3rd HD cams. One of them, however, has a problem: the computer doesn't see it.

It acts fine in every way. It turns on and off. It records. When I plug it into the PC - on a known good USB cable - the red LED comes on. When I press power, the yellow LED comes on. But the computer doesn't see it.

I've tried changing out the memory card. No joy. I can put a memory card in it, record a scene, put that memory card into another camera, plug it in and read it. But the PC just doesn't acknowledge that the problem cam is there.

It seems like the USB connection on this camera might be bad although, as I said, the camera red LED comes on when I plug it in, so the power's coming through at least.

Any ideas? None of the problems on page #1 really sound like my problem.

It sounds like the usb plug of the camera has a problem, as you said.
I would try another cable, even if this works on some other cameras, and plug it directly to the motherboard, not in the front USB of the case.
Using no extension cable.

If the same PC port and cable works fine with the other two cameras, then they should be OK. It could be a dirty, bent, or broken data pin on the mini-USB connector. Have you tried the webcam mode yet? If webcam mode works, then the USB plug data lines in the camera are working. If you can't get into web cam mode either, try cleaning the pins in the camera USB plug. Wet the cable end contacts with alcohol, or better yet, Corrosion-X, and repeatedly insert/extract the plug a number of times to see if that helps.

Richard,
Thanks for your fine effort on clarifying the source, and reducing the problem.. Good Show. generally i'm not really yelling at my buddies but the wind and ambient noise at the distance they are from the mic relative to me under the hat is just too much for the MIC to handle conversations without considerable distortion. I may just mod one and see.. since I'm pretty sure I'll need to replace the lipo in one or two fairly soon anyway.. Thanks Again..

I've never used ANY of my cameras in webcam mode, so I'm not sure what I ought to be seeing.

My instructions say press and hold both buttons while plugging into the PC. I do this and get a blinking LED: yellow - red - yellow - red.

Again, my computer gives no indication that it sees the device out there.

I'm using the same USB port and cable that I use for all six of my cameras, HD and not. I have had charging problems before going thru a hub, so I don't do that anymore.

No luck with the alcohol.

Tom,
thanks, i used all three cams to cover several RC sailboat races this weekend and find I myself restarting the cam over and over after the one or two long runs, This should be expected i guess .. but not after just 2o to 30 mins as it is now on a couple of them.. I suppose I'll need to rig the pin 4 Ext battery connector to avoid this, and record while the Ext Lipo is plugged in. The audio beeps are irritating and I cant really tell if the things have properly recharged doing it in the field. the Jumbo coming may bypass the problem for a while.. one thing is certain i never thought I'd be taking so MUCH video on these silly little cams but they are so convenient by comparison to a real camcorder.

When you said the camera is not recognized, I guess you don't get the audible tone the PC normally gives either when it loads the driver for the removeable memory? Sounds like it's back to the vendor on that one!

Try this procedure (leave the cable attached between the camera and the PC) :

Briefly press the rear button to switch the camera on as normal.

Usually, the yellow LED blinks twice before it enters standby or file transfer mode (as when connected to a PC).

As soon as the LED comes on for the first time, press & hold the front button down for 4 seconds - longer is OK.

It will flicker a few times, go out and glow steadily again - you have forced the camera into webcam mode.

Attached is VmCam, a small 'AmCap' variation for testing your camera / webcam.

I'm going to 'lie low' now - agreed, far too much boring technical stuff, advice and pictures...

Good luck all, Richard

Hmmm... That worked. And my first test of it afterwards, without the tricky timing, worked as well.

So thanks! I'm still not sure what's going on here, but it worked twice. That's a big improvement.

Hi friends,

Just say thank you for this thread, which is amazing.
I got a 808 #11 camera and it is a really great.

My planes are parked now, but I uhave used it for airsoft, so I mounted it over my G36K airsoft rifle and this is the result. Edited with iMovie.

Enjoy . Cheers

I, for one, find your tests just as interesting as the flight videos and thank you for sharing. For me, they are not boring at all! - Actually they are quite exciting!

I would do the capacitor swap without hesitation, but since I don't want any sound on my videos there's not much point! Also, I would first have to buy a "book" (set) of SMD capacitors to play with.

I also love you supply voltage test!

Your tests help us understand the #11 much better and maybe even inspire the manufacturer.

OK, I guess we're in the minority here... ... but should you make any other amazing #11 tests, please do post the results.

Your tests help us understand the #11 much better and maybe even inspire the manufacturer.

OK, I guess we're in the minority here... ... but should you make any other amazing #11 tests, please do post the results.
ditto.. I feel exactly as Iso does.. please don't give up.. I'd like to see more tests and mods.. for sure.. JimS
