Ordered mine. Can't wait.

Tom Frank, any luck with removing the 20 minute limit?

Not yet. I was told they could do it if there was enough demand. They seem to feel 20 min. stop/save function is preferred by most users. I'm not one of them as long as I have plenty of battery life, and now that the external "emergency charger" is available, the recording time can be boosted to about 5 hours +- an hour with a single 2000 mAh AA cell.

The more people that ask for this, the better then chances of a new firmware for this, but i'd want to still be able to keep the date stamp turned off along with it.

I'll ask My Camera Guy one more time.

Hi Tom,

I would prefer no save and continue function so long as the camera can reliably save the file when a low battery is detected.

As for the recording time on a single AA cell; Unless you have determined it yourself I would expect the up time to be much less than that. These things can be hopelessly inefficient as the voltage is stepped up in the emergency charger and stepped down in the camera charge circuit. I would not be too surprised if it was only about 60 to 90 mins. I hope I'm wrong!

Yes, I think the same. Assume you take a 2000 mAh AA battery at 1.3 V or so. Needs to be stepped up 4x to get 5V. So it would need 4x the current. So you end up with an equivalent 500 mAh 5 V battery, IF conversion is at 100% efficiency... Then it needs to go through the charger circuit (I assume it charges the internal battery, like the car adaptor). So in the end, so I would be curious to see if 5 hrs recording time is really achieveable...

But for sure it will be longer than standard .

Tom.
There is a problem with the 'normal' FAT32 format used on Flash cards - a limit of 4 gigabyte file size.
the 20min save and re-open yealds a file less than 2 Gigabytes long, & Looking at the numbers, that is probably a safe value, as 2gig is the max if the 32bit number used to store file length is used as a Signed Integer, 4 gig if it is used as an Unsigned Integer - a common GotchYa for programmers.
So - removing the 20min close/opennew restrictiion will rusult in a quiet phffut as the fileing system retires hurt, or at least garbages the file....

Earlier there was mention of a dedicated battery charger chip on the camera board.
There are such chips available, and implement the 'normal' Lipo charge cyclye :-
Charge at Constant Current ( usually 1C e.g. 240mA for a 240 mAh cell) until the cell voltage is 4.2vots.
Then charge at Constant Voltage until the current drops to (typically) less than 10% of the CC rate.
The battery is now fully charged.
This accounts for the brief red flash when a fully charged camera is plugged into USB - the charger chip goes through all phases very quickly.

with a bit of a hackapendectomy you could fit at 5000 mAh NMIH cell e.g. http://www.overlander.co.uk/batterie...?prop_size=197
Which could give you apx 3 hrs...

On my #7, I just removed the battery and added a servo connector. Can run off the balance tap of a big lipo, or the original lipo externally

But the internal clock will stop without battery, so will have to be reset each time you power up.

With the #7, you lose the date/time setting but not the user configured firmware. Since most of you remove the date/time, it's probably not a problem. But please don't brick your camera to prove me wrong!!

PS - disconnecting the battery and then reconnecting acts like a hard reset, the cam is ready to use

The most helpful person is the thread starter, Tom Frank.

In addition, you should bookmark Chucklohr.com. It is a blog of all the different types of keychain cameras. I believe this HD version is # 11.
Thanks for the info (and saving me a lot of time reading through the whole thread).

Tom Frank sure did an excellent job keeping everything organized.

I plan on ordering one or two of these HD key chain cams in the next few weeks... can't wait!

Wow great thread. I stumbled upon this just in time, I was about the order the new FlycamoneHD cams but order one of these instead

Cheap enough to put on a floatplane and get a little crazy.

Wayne,

It is just very practical solution to those who want to take on board videos. You can simply just use it or go through improving it by removing the time stamp or refocusing it. If you want simple, just charge it, slap on a piece of good velcro (fuzzy side on the camera and hook on the plane). To aid adhesion I use Uhu Creativ contact cement for foam to really bond the velcro.

Enjoy.
