Very simply put, if you connect the positive output of the 3S lipo pack to the TIP of the cigarettle lighter plug, and then connect the negative output of the lipo pack to the CORRECT one of the two side contacts on the lighter plug, it will work just as if it was plugged into the car cigarette lighter socket. It's important to note here that there are two contacts on the side of the plug on the car charger, but only ONE of them is actually connected to internal ground. The other is not connected to anything, so if you get the wrong one, you'll notice that the red LED on the charger will stay dark. You know you've got it right when the red LED lights up.

I tested it, and it works fine. The only problem is that of course it's bulky and awkward. The whole system can be made far more compact and elegant.

Note that when using the car charger, the red charging light on the camera will NEVER come on, period, no matter how you power the charger. This is normal operation because this type of charger is using a different circuit inside the camera to charge and run the camera at the same time. Seems bizarre to me that it is wired the way it is, considering that most USB-charged devices can run and charge at the same time anymore, but whatever works.

You know... With a little ingenuity, a tiny LED could be added to the camera casing with a little series resistor, and provide at least an indication of applied power, so that you know that things are working. Maybe I'll do that too.

It should only do that in the editor. When you output the file (with an audio codec compatible with the file container type), the sound should play properly. Do you have an example where this is not the case?

I had a problem with snow collecting in the lens opening on landings and this would have prevented that. You should do another piece that snaps into the bottom to make it flat on the bottom and stiffen it up. You should also send me one.

Nice job.

I have alot more respect for people who design packaging cuz it wasnt that ez to design and make...Its form fit so it doesnt rattle around and buttons can be pushed without removing the cam...I think the video is pretty good concidering its recording thru plastic...thanks lostheli...I did make some with flat bottoms but camera needs to be held to top...There should be many uses for these kam-kozys...in michigan if it isnt snowing...its raining!

With the big plastic lip, how will you mount it on your plane?

Just additional data point, the camera adapter for the iPad allows connection of USB devices, but even if the camera is fully charged, the iPad disconnects the camera immediately stating that it draws too much current. What happens is that it always tries to charge, even if it is fully charged, for just a few seconds.

You can, though, pull the microSD card out and use it in an adapter using the SD card attachment. Unfortunately, the videos cannot be played on the iPad.

This just blows me away! This minute camera draws too much power charging a 250mAh battery??!! Either your iPad USB port is defective or so sub-standard it is not good for much of anything useful. And for the iPad not to play a .MOV file, an Apple STANDARD, is just... well... I'll leave it at that!

Sorry to be so critical, but I've read too many comments from Apple fans whenever a problem is mentioned about a Windows PC, they say "Get a MAC!"

I doubt this camera produces files that truly comply with Apple's Standards.

An iPad is NOT a Mac.

iPad/iPhone/iPod Touch's standard video playing capabilities are limited (even supporting a limited number of resolutions). There are two solutions:
1. Convert the video files on your desktop PC (or Mac) to MP4 specific for iOS (Mpeg Streamclip does this quickly and perfectly)
2. Use a different app on your iDevice to play the files. VLC was good (and free) but was pulled from the Appstore because a killjoy developer of the desktop VLC objected. Possible alternatives include BUZZ Player and OPlayer (I haven't tried either of these myself, so cannot vouch for their suitability).

Like Tom, I can't believe this!! So you are saying that even when the battery is (partially) discharged your iPad can't charge this tiny camera? Can the iPad charge other devices - I doubt it.

Unfortunately (fortunately?) I don't have an iPad to test this, but if you can confirm this, then I'll certainly add it to the post in question.

BTW, today I added more information about the car battery charger to the post in question - if I've forgotten something please post.
I hope to cover the Emergency battery charger next week - but I have tons of information on that...

These are the video specs - looks like the bit rate capability is lower than these cameras produce

Of course an iPad is not a Mac, but it is an Apple. You'd think they would given the state of the art iPad a modest USB 2.0 port with half the standard 500 mA capability as a minimum, enough to charge the camera battery at 1C. Maybe iPad2 that was just released has addressed this, and other HD play issues?

Anyway, I think you are right about the non-standard .MOV file. Although I can play and edit the camera's native .MOV file just fine on my Windows 7 (64 bit) PC, when I simply re-package it via a direct stream copy into an .AVI container, no video comes through on virtually all player/editing programs on my Windows box... only audio. I've tried this with a couple of different re-packaging programs, and I know I have all the necessary codecs, so it is a packaging problem. The only program on a Windows box I've found that can get any video with the direct stream copy .AVI file is the VLC player, which seems to overlook whatever inconsistencies there are and go right to the video stream content.

A direct stream copy of the camera's .MOV file into an .MP4 container DOES copy, play, and edit perfectly, though. I wish they had implemented the camera's native file format as a more universal .MP4 file format to begin with, or even .AVI format for that matter.

OK, it's the processing power of the CPU that's the bottlneck, and not the .MOV file itself more than likely. The iPad 2 has a more powerful processor and touts 1280x720 video, so maybe that's one reason they so quickly released the iPad2? Anyway, I'll stop... don't want get this thread off on a tanget.
