Nope, I still picture a big barrel of cameras ready to be packed and shipped out.

It looks like there's a need to use some better way to identify the camera type or vintage before doing the date stamp removal. The EXIF data attached to JPEG images from the cam might help as a fingerprint.

BTW some of the old #3 types that went catatonic were restored by hard reset - that is by disconnecting the battery. However best to send it back.

I noticed that in the webcam mode, the HD Key cam has a video delay in movement about twice as long as the Key cam #3. Could be due to the higher resolution, but the regular webcam I use has 10MP and there is no delay. Of course I got it to fly with and didn't get it for web cam use anyway
Cheers,
Jim

I used the HD as a webcam on skype and the first thing others noticed was how clear the picture was.

Yeah I agree, I didn't get it for a webcam and doubt I'll ever use it, but it's definitely a nice one! Nice and clear picture for sure.

Did you try the trick that worked on a lot of #3's? Remove the SD card, then turn on the camera. The #3 would blink 30 times, then shut down automatically. Put the SD card back in, power up, and see if it works. Well, worth a try at least.

Got Mine!

My HD key cam arrived today! So now I can play with the real deal. I just shot a few test clips to make sure it works, and a web cam test, before putting it into a run 'til it dies stop and record test to see if my files are properly saved. Once that is done, I'll do the date removal.

I had to stop these activities to watch my Seahawks embarrass all the football prognosticators and odds makers! Great game... quite a difference when all the starters are back healthy, play hard, and make few mistakes. My condolences to Saints fans!

Glad you got your camera. Don't brick it!

A good video of a good flight can sell hundreds of planes in my estimation. There's lots of lurkers out there that will get in and never post (again my estimation). Keep up the good work.

Pasta, my #8 is 15.6 grams with soft velcro side attached to top and bottom. My hd is on the way. I would guess not much more. Oh I removed the keychain part.

Thanks wheelspinner - Thats so useful to me. I've been working on a dc dc converter to power the camera from the heli 3.7v cell I'll post something about that soon - Hoping to remove the battery from the camera to save some weight.

DC DC Converter for HD Key Chain camera

Tested this on a standard def keychain - Purpose is to use the heli battery 3.7 volts to power the HD key chain. Input voltage range is 2.5V - 4.5V output is stabilised 4.3 volts ~ 300mA max it will also do 9V O/P for 2.4Ghz tx. Cant wait to try it out on the HD keychain when it arrives. If anyone wants the circuit then let me know.

Hi wheelspinner - The main IC is surface mount - Its just a birds nest ) - Hell of a job to solder surface mount IC - Yes it would save some weight if I did a mini board - The problem to power anything off the main heli battery is that it drops quite a bit under full load. Thats why the power unit is ok down to 2.5V at which point the heli would no longer be flying -

When you confirm a working connection to the HD key cam, come back and edit this post, with a circuit diagram and any hook up instructions, tips or tricks, and I'll include it in the Frankencam reserved post #4 for stuff like this.

I doubt the camera will function down at 2.5V input either!

OK Tom I sure will - Still waiting for the HD key cam to arrive from Hong Kong - The battey in the HD key cam looks like a typical 250mA 3.7 lithium and so I'm pretty sure it will work OK - Its quite efficient ~ 80% and I'm hoping the current drain will be be low compared to the heli motor - Hopefully the HD key cam will be here next week - Thanks for such an interesting thread.
