The M12 lenses are big, but might be useful for someone looking for something different. The B lens, for example, has lots of vignetting, maybe a M12 lens could give a better result for that application.

Here are mine on a Vivitar. A D lens is shown for size comparison

FWIW, the #16 camera developer has worked diligently with lens suppliers to get improved lenses for the camera. I don't think you will find many ready-made lenses that will fit the camera, or a better one if it does, than the ones you can buy from the camera vendors. Good luck.
Thanks for the reply. I'll probably not bother to mess with anything and be happy when my new A module arrives.
I'd like to point out that battery life is all over the map.
Also after looking over videos made with the first version in daylight and artificial lighting and comparing to the new version shots in similar situations all I can say is WOW!

If talking about M12 x 0.5 lens...have you ever reviewed this? I got it from the original 808 #16 thread under hacks.
http://s134.beta.photobucket.com/use...16724627926203

I used this as a guide and have converted two cmos 7mm lens cameras to m12 lenses.
I'd sure like to see some images before I go about it.

If somebody here with linux, please test it by turning camera on to webcam and opening terminal.

Type: lsusb

You see usb-devices which connected. Something like that:

Bus 001 Device 002: ID 80ee:0021 webcam

Than type: lsusb -d 80ee:0021 -v | grep "14 Video"

If the #16 is a UVC device, you should see a number of lines that look like this:

bFunctionClass 14 Video
bInterfaceClass 14 Video
bInterfaceClass 14 Video
bInterfaceClass 14 Video

In this case the Linux UVC driver should recognize the camera.

Thank you very much
On Ubuntu 12.04, connect camera first in webcam mode then start Cheese;
it works fine.

I like this idea, and am probably going to go with it. an excuse to buy new batteries

the problem is finding a larger battery that will still fit inside the battery cradle, there aren't many options that will fit. I have the camera mounted under the cradle right now, and I'd rather not have to do any major modifying to the frame as I want to keep it mostly stock. I have these Nano-Tech 300mah batteries but they don't offer longer flight time. I also feel their performances deteriorates quickly.

if I go with something larger like these Walkera 350mah, the extra weight can begin to become a factor (around 10g). thinking about these Hyperion 240mah, the bare battery weighing only 6.5g. even though they are smaller capacity, I'm thinking maybe the high quality of these packs will prevent the voltage to drop down to 3.3V under heavy load. don't know which between the two would work best!

By definition, the camera shuts down at 3.3v, the rx/esc low voltage shut off is lower - you proved that.
So getting a Higher capacity main cell will get more flight and video time, but the camera will still shut off before the copter plummets on lvco.
The only way is separate batteries but that == overload(Mr Newtons' version) in stead of overload(Mr Voltares' version)
Get a bigger battery, and land just before the camera goes on strike

I had no intention of connecting them in parallel or charging them together (I would've charged the 20mah batteries together though). I was planning on having the 20mah or 30mah lipo be dedicated to the camera, and use the flight battery separately to fly the Ladybird as normal. many of the micro FPV quads go this route because sharing the flight battery causes interference issues from the motors. my idea being that I want to be able to capture aggressive flying on film, but doing something like a flip causes the voltage to drop even lower momentarily, and could be enough to shut off the camera with plenty enough battery left to fly the Ladybird for a few more minutes (I know using brand new batteries would also help this). my 3 minute time was very basic hovering only. having a second very small battery could allow me to fly as aggressive as I want and not worry. I know I can use a battery much smaller than the one that came with the camera, I was curious just how small I could go! adding a gram or so weight to achieve this would be 'acceptable' hehe.

I understand having a larger flight battery will also help, and is easier all around. that's why I went that route initially. just checking my options

I think I might get several new batteries anyways, just trying to decide between the two above. I can always try my idea if it doesn't work out.

I appreciate both your inputs. sorry for going OT but I was sent here from the mini multirotor forum

I'm not 100% sure it has all 5 wires but guessing it does.
For 38 cents plus shipping it's probably worth a try - I have one in the shopping cart right now

Easy. Do an eBay search for "mini usb 5 pin". One of the first results will lead you here.

You won't find a finished cable since pin #4 is device dependable. Use a video or audio cable cut to length. If you are inexperienced in soldering, I suggest you buy a few spare plugs in case you mess up. I always fill the plug with hot glue before putting the plug together, but you need to act very quickly and apply the exact amount of glue. I guess silicon would be an easier solution, but it takes ages to dry.

I doubt it very much indeed, and the plug is almost certainly not designed to be opened up!

My intention is to cut the full size USB plug off the other end and then wire up the correct plug for video etc.

The full size USB plug only has four contacts, so chances are 1:million that the manufacturer would use a 5-wire cable. I also doubt the mini-USB end even has a solder point for pin #4. However, if the cable would have 5 wires, then you've found something very useful indeed.

Yeah .. I just tried that with 4 wires .. all of them had only 3 pins + GND exposed .. and Pin 4 is basically a dummy pin.

That 5 pin connector has the same issue .. only 3 wires are exposed (5V, D+, D-, GND is the case) .. Most likely the 4th pin is a dummy pin as well.

hmm. gotta check Fry's or RS tomorrow.

Thanks,

Ok .. found actually one on ebay:

http://www.ebay.com/itm/10Pcs-Mini-U...item27b739bfaa

See Pin 4 is exposed .. so that actually might work ..


Correction: I just checked the diagram and Pin 4 is dummy on the above one. So only the one below works.


Also this works, but soldering is probably a bit more though:

I have not been able to locate any mini-USB plugs with 5 solder points locally.
Like you, all the plugs had a dummy pin #4. The only place I've found is eBay (or Alibaba). The link I gave is a very reliable seller. I've purchased USB items from him a number of times.

These are sockets, not plugs. They are designed to be soldered onto a circuit board. My original link also supplies these.

And then, the good news:
CA with USB communication on Android: following several requests, I am looking into it again. I am currently finalizing an Android preview 2B-mini GUI with full-features USB communication. It should be available for download soon; stay tuned...
Sorry,but I'm going to ask some dumb questions here. I don't know exactly what the above means, but I'm guessing it means even if the additional hardware could be added to the #16 there would never be a wireless App for ipad like the GoPro,but there could be for Android. So what might be possible?
I did search "wireless" and "ipad"but couldn't find much, apologies if I missed it.
