I get real pleasure from reading your hardware hacks and want to thank you for your excellent, well written, articles. Last year one of my #11s started acting up when the ambient temperature rose above 32°C (90°F), so replacing the regulator may help a bit, we'll see. You have done some really great detective work, and so well explained. Thank you so much. |

I cannot understand if each USB has 5V and 2A or all together. Do I have to use the standard USB cable given with the cameras? |

Im having a problem with my camera. It was working fine then after taking some videos it wont turn on. It seems to charge fine and the battery is holding around 4 volts. When I try to turn it on the yellow LED shines for about a second then turns off. The PC wont recognize it when connected. I have connected another battery which works and the same thing happens. If I connect it to the car charger the LED turns red and when I try to power it on the light turns yellow for a second then turns off.
Any suggestions would be greatly appreciated |

![]() If I play directly from the camera or drag and drop a file onto my desktop it will play with quicktime, VLC, WLMM or MP4camAVI. It will not play properly with WMP. I cannot save from any of these editors without some corruption. Usually pixelated lines though them and colour variations. I have had some success with avidemux being able to convert files to AVI. It seems to have varying quality depending on the video format selected. Mpeg-4 ASP being the best so far. Can anyone give me some tips in selecting the best settings in avidemux. At least I am beginning to make some progress now, so thanks for the help so far, much appreciated

It's one of those things that are easy, but only if you know how... ![]() the Voltage is the pressure of the electricity. the Current is the amount of electricity. The USB port on you computer has 2 power wires (and 2 signal wires for data). The Voltage is specified as 5 volts and never varies (not quite true, but as near enough for this explanation). Inside the camera is the battery - it is always quoted as a 3.7Volt battery, but in fact it varies from 4.2 Volts when fully charged, to 3.0volts when fully discarged. In the camera is a charge circuit (or chip) which takes the 5Volts from the USB socket and reduces it to charge the battery. The battery is a 240 mAh battery - that is :- it will provide 240 mAmps for 1 hour. The Camera uses about 300 mAmps, so the battery can run the camera for about 40 mins from fully charged to fully dischaged. The charger chip in the camera will control the charge rate to something less than 300 mAmps (it is what the battery needs, trying to fast charge the battery reduces the number of times it can be dischaged). Some wall chargers conform to the USB standard of supplying no more than 1 Amp (1000 mAmps), others will supply upto 2Amps ( but only IF it is asked to ). When the camera is recording, it needs 300 mAmps (0.3Amps), and this extra power comes from the charger IF it is connected. So a 1amp USB charger is fine for this camera. But other devices could ask for up to 2 Amps and the 1 Amp charger would just refuse to do this. Remember that a charger of this type only provides the current asked for by the charger chip inside the device, it never pushes the 2Amps, it just has 2 amps available for use if asked for. does that help? normal USB cable is fine, the signal wires are left unconnected and they do nothing.

Hallo SuperMike, I had some questions to ask. 1)Can you tell me how can I find the version number #-- of the car keychain camera? where is it written? its not written on the box and leaflet. 2)Is it necessary that the firmwareupdate of the #11 should go to the #11 version camera only? 3)My camera does not record while charging. Even if I start recording and then attach the usb, it stops recording. Does this feature comes through firmware update? 4)I have found out that my camera gives 600mb of file for 30minutes of video in low light conditions, and gives more than 1gb file for 30minutes during day light. so much difference. Is this normal? 5)Can the 'data size:video' ratio be controlled, so that I can record more video on the memory card? Thank you very much. talk to you soon. |

#11 or #18?
I bought four #11 cameras from eletech086. The first one looks a normal #11, while the other three seem #18 cameras.
In fact, the mini-plug on the camera looks like the one normally present on #18. In the picture below, I compare the #11 (top), the camera I bought from eletech086 (middle) and a #18 (bottom). http://i48.tinypic.com/11rybzt.jpg Even the battery is connected like #18. See the picture: http://i49.tinypic.com/97lgqx.jpg The seller insists they are #11... What do you think? Are they #18 or a new version of #11? |

).Chuck identified the #11 when it first came out. The developer then 'improved' it (video out) and decided to call it a #18 without contacting Chuck - this cause a bit of 'muttering in beards' and then suddenly it seems the developers decided to call it the improved #11. and the designation #18 sort of slipped out of use. I could be wrong, it it may be my beard that is being muttered into ![]() Mike (Highly reflective undies ON.) |

intensive use as videocamera
Hi.
I spent my holidays in Sardegna, Italy. So I tried both my cameras, Panasonic FZ 150 and the keychain # 11 version. I bought it last year. I made a little video for all you, if you want to see it. It isn't aerial video, but in this sample I use only little # 11. I think is very very good, not very far from professional quality of the Panasonic. The only problem I had was the horizon, often not perfectly horizontal. It needs a micro bubble level on top.

Hi,
I read Isoprop's post #2093 and fashioned myself a special charging cable using 2 core wire and the pin-out described. I've used 2 rel 2 firmwares for my #11, 20min and 70min from post #3531. When I tested recording with the cable plugged into my computer the camera successfully stop/saved/continued to fill the 16GB SD card. When I plug it into any of my battery based USB chargers, similar to those used in Isoprop's post, with the same special cable the camera will stop recording at the end of the first file (as it would with a standard USB cable!) I've tried it several times and I've measured the charger voltages and they are pretty much exactly the same as the computer, about 5V. My main USB power supply is rated at 5000Mah and 5V 1A output. Does anyone have any idea why this could be happening as I'm completely stumped. The camera is definitely charging as it will record as many times as I like as long as I start it manually. |

120 deg Jumbo with AVOUT
Quote:
But here is the one with AVout: http://www.htinter.com/full-hd-120%C...k-no_p236.html It has a AVOUT cable and the description states that it can do AVOUT when recording. Anyone can confirm this? Looks like the best candidate for FPV for me among all keykams. ![]()

new #11 or #18?
Quote:
How can I understand if it is the new #11 or #18? Can I try to install the #18 FW? Do I risk to ruin the camera? Is it possible to overcome the block and install the #18 FW? Is it convenient? Sorry for my numerous questions!

No way to tell now other than by seeing if it has video out capability after you get one. My understanding is the FW will no longer load... just gets blocked, but I've not tried it. I have no idea if the block is defeatable, and would not report it here if I did. It was put in because of the reason you are asking about... people wanting to save a few $$ by buyibg a #11 and flashing in the #18 FW and trying to get a free video out cable also. If you want video out, buy the one that comes with it and the proper cable. it's not that much more expensive. |

In reality, at the beginning, when I received the first camera and I thought it was #18, I installed the #18 FW. I had some problems which I solved in part and I am still working on them. Installing a wrong FW could be an explanation for these problems. |

Is what you call "New V2 #11"? So the FW is this one: http://www.rcgroups.com/forums/showp...postcount=9323 right? I want to be sure. In post #2, you used v1, v2 and v3. I think they indicate something different, isn't it? Different circuits of #11? |

In post #2 I was referring to different revisions to the circuit board, all of which still had the CMOS ribbon cable soldered to the board and the original standard miniUSB plug. V2 #11 camera has the smaller non-standard 8 pin minUSB plug, and that's what the FW is relating to... camera version, not circuit board revisions. So if you have the one with that smaller 8 pin non-standard plug (and no video out cable), then you have the V2 #11 and should only use the V2 #11 FW in it. Sorry for the confusion, but what's done is done. I've opted out of further support since I don't have the camera, and only posted the V2 camera FW because the developer ask me to do it. I will now slink back into the shadows...

...and I installed it and it seems to work properly. The only thing is that I found a discrepancy in the instruction to install the FW. At the point 3), I left the camera on and I plugged into the PC, but nothing happened. I needed to switch off and on the camera with the USB cable on in order to make the PC recognize the camera as an external HD. The led light flashed again, as the FW was loaded again, but at the end everything seemed to work well. Maybe this can help other users. |

The video is in AVI and can be played with no problems. I can open and play it with avidemux 2.5, but I cannot easily move the cursor up and down to find the points when I want to cut the video. Even if I can do that and I save the video, the output has problems (it doesn't contain the video or it is corrupted). |

Hi people,
I used my V2 #11 to record a sample video and check if everything works. The video shows some noise, a brighter zone on the right which increases over the time. The video is 40min, but I selected some clips to show you.
I specified the video was recorded with V2 #11, but I met the same problem with a #11 jumbo some time ago. A possible explanation for this artifact? Is it possible to avoid/reduce that? |

Ginetto, looks like glare/lens flare to me. Try on a subject with good lighting.
Here's my modded cam going for a ride on my Bird of Time. The orange covering seems to force color changes when the sky comes into view. Wish they had one with manual white balance.

Mike, Yabba, thanks - you guys crack me up!! I admit, I'm a bluegrass addict, dragging my wife every weekend to jams or free concerts. She's now crossed over to the tolerance zone. I have picked up some CDs from local bands, so am well armed for more videos...
I sent that video to a few non RC buddies, amazing questions "was that out of the window of a plane you were in?" or "how many engines does that plane have?". Ginetto, I played your video on Vimeo, andI think the noise is due to compression of the low light areas. It seems normal, just avoid large areas of shade. |

Big Lama flight at the harbor this morning- video
Finally had some decent weather and calm winds at the harbor this morning. Flew about 30 minutes! Of course had to edit it way down for the video.
Put in about 8 packs. Towards the end an offshore breeze developed and had to struggle a bit to get it back over land, but it did well. Kinda scared me lol as I'd hate to get stuck out over the water and no be able to get back in. Was a great morning and flew the E500 too still trying to get it trimmed right. Getting close. Weather holds more over the water flights coming. This was just a test of my nerves. Heli and cam (808 HD #11) did really nicely today. Anyway Video is in in HD (720p) and best viewed in YouTube. Feel free to stop by our public Big Lama Facebook page at at http://www.facebook.com/ESkyBigLamaPage

Hi can anyone tell me if my 808 is a #11 please?
![]() the chips on the board dont match any on the "chuck Lohr" site that i can see, but the closest match i have found is the #11 thanks i bought it off a ebay seller called internet-shop365 heres a snap shot from a very muggy day

Since the lens is soldered, if it is a #11, it is an old version. Another tell-tale is the size and names of the files. I don't have access to my old #11s at the moment so I can't tell you how the files are named, but if you would post the file names it would be helpful. Can you set the date and time using Nr11Timeset.exe? Is the output file H264 (1280x720)? |

battery problem ?
Hi .
Last sunday I tried my # 11 full charged . Tied it on top of my son's hat and record a first person adventure in the nature. But only 33' of video was recorded, and the last 15min was a sequence of buzzing sound. I tried (at home)a new record with a 600 mAh LIpo battery connect to usb plug using special cable. Manually stopped the record after about 40 mins.. and all video sequence was a buzzing dance.I don't understand why.. I'll try a new internal battery.. I'm very disappointed, I love video quality of this cam and I'm afraid it is dying . P.S. Sorry for my poor english

2. The USB requires 5V +/- 5% max., but I very much doubt your LiPo can supply a constant voltage of 5V under load. If you use external USB power you should use specially designed USB battery packs. |

What do you think about a parallel connection with 2 lipos (the internal + one ext.) ? Can I use a jst plug for ext battery, so for just few minutes records the internal lipo is enought, and for long time records plug the second battery ? It's dangerous ? I have noticed during record the cam is very warm, I don't remember this few months ago.. |

If you know what you are doing, then an external LiPo in place (instead) of the internal LiPo is acceptable as long as your external LiPo includes the protection circuitry included in all #16 batteries. If you are unsure or inexperienced with handling LiPos, then external USB power is the easiest (no need to open the camera) and safest method, especially when weight is not a problem. Very small external USB batteries (about the size of 4 AA cells) can supply power for over 10 hours of continuous recording. It is normal that the camera becomes very warm during recording. |

If you know what you are doing, you can obviously get away with virtually anything. However, if you don't understand that LiPos mustn't be allowed to drain below a certain voltage and current must be limited while charging and a whole lot of other factors must be respected, then don't even think about connecting external LiPos without a protection circuit. Obviously you know what you are doing and don't connect USB power while your external battery is connected - I dread to think what could happen if you did! Another disadvantage is the RTC will be reset each time you disconnect the battery so your files, and possibly your video, will be incorrectly time-stamped. You would, therefore, have to set the date and time each time you recharge your battery. This may be acceptable for some people, but for me the whole process would be far too inconvenient. |

With my project I can use a bigger lipo, but I charge it with a dedicate charger, not with internal circuitry. When I switch from one to other battery, I'm not sure the RCT will be reset, because the disconnection time (I think) is very very short...or not ?

. Just don't let the external battery discharge too much if it doesn't have that circuitry built in.The RTC will reset immediately it loses power. I doubt there are any large capacitors on board that will hold the power for more than a millisecond or two without a battery connected. I would expect a switch like you showed will disconnect the internal battery for at least 100ms, most probably longer, but it would also depend on how quickly you make the connection. These are just assumptions based on experience. Someone would have to try your switch idea first, but even if it worked, I would think it's still a hit-or-miss deal if the RTC resets or the camera's firmware may even "hang". But go ahead, prove me wrong

V2 - Restoring original firmware?
Hi,
I flushed this firmware: http://www.rcgroups.com/forums/showp...postcount=9323 And I want the led off when recording. Is it possible to configure it somehow? Is it possible to restore the original firmware for V2? Thanks! |

Quote:
If file date is important, I put an approximate time/date time.txt file on the root of the card, and it sets the time when the cam is connected to the battery. I don't think the switch would work, but never tried. There's a very low risk of running the external battery too low because the cam will shut down at 3.6v. leaving only the clock running. I never leave the cam connected to external supply anyway.

ActionCam Meets Disc Golf
I wasn't sure where to post this, but thought you guys might appreciate this video. We took an ActionCam, made a special mount, and mounted the camera to a Disc Golf Disc (similar to a Frisbee) The video came out amazingly well.

Thanks guy! What I did in the mean time was get a female lead from the hobby shop, cut out the old batt, make a notch for the lead to hang out, solder on and attach a eflite CX batt w/Velcro to the side for a hat cam. 160ma ought to get a few 4-5 min flights for Doppler speed checks etc! Works like a charm and best of all is, no more beep beep beep on the vid! Seems as the vid quality has improved vastly too! I forgot how good these were!

man if we could get firmware that would auto start stop with outside power (ie start engine on stop engine off) and loop record with avi for no "gap"
this would be "THE" killer CAR DVR especially with the D lens. they are so cheap and tiny you could run TWO so you get tight and wide shots. |
