450 Helicopter Mount for 808#16


Thought I would share. I made a mount for the 808 #16 for my 450 helicopter. It is simple and quite nice. I had to replace my gyro mount for a longer one, so I used the stock mount and a few linkages along with 2 rubber canopy fasteners to make a stiff but adjustable mount for my camera.

More pictures are on my blog.

from what I understand making the interface on android is actually pretty easy (I can't do it but you get the point)

the hard part is the "talking to the camera" part.
At last I know what you are talking about

I don't have the DLL code for accessing the underlying USB communication. It is a DLL and has nothing to do with the GUI. It works equally well from the command prompt.

The DLL is closed source and was developed by the chip manufacturer, not the camera developer. With all this non-disclosure stuff I would say your chances of getting your hands on the code are NIL. But similar to what I previously posted, the code will use Windows APIs so would be totally useless for Android!

Once again, I don't understand all the fuss. If you find someone who understands the USB part of Android it should be a piece of cake for him to implement the interface - just sniff the data moving over the USB bus. Even someone without any programming knowledge whatsoever can do that!

According to therau2000 no public USB libraries exist for java, but he's researching...

Yes, java is a pretty simple language, so programming an app should be no great deal. Using the USB interface is a different story.

True.

The Android core is written in C/C++, as far as I know. Most probably a bit of assembler here and there too.

Using Java for the App layer was most probably a very wise decision.

ahhh THAT is the magic part. the dll. ok I get it now. so your program does not interface with the camera you interface with the DLL and THAT interfaces with the program. ??

Drat. I am guessing that android can not use or sim dll ? "I HAVE" run windows 95 on a droid so it might not be totally impossible but probably too much work in general. Pity.

Does any one know the answer?

It will be smaller on top and bottom due to the formatting of 16:9 to 4:3 on the display. Just like watching a wide screen movie on a regular tv...

The Android operating system is an off shoot of Linux. Absolutely NOTHING written for Windows would run in the Android environment, that includes exe's dll's api's etc.

All the Andriod app's are written in an Android environment of Java, again no Windows code would run in Java.

So the upshot of your requests is that you would need to rewrite the Android app you want from new in Java.

Starting with a print out of the windows listing of the GUI in order to rewrite the code in Java would be completely utterly pointless.

nono. the reason I wanted source was to get whats in the "dll" as I now understand it.

NOW I understand your replies since there is no "camera code" in the windows program. its all in the DLL (I did not know this part)

I still need the source but of the DLL and since that is "not available" I doubt this could work. real pity as that would be SO convenient.

#1 no "cool factor" doing it that way.

#2 can not do real time "time setting" that way

#3 many phones you have to turn the phone off extract it from your case remove the back remove the battery and THEN you can get the card out. Boot it naked do your stuff and put it all back together again and boot again :-) no fun :-)

A DLL is a pure windows construct, and expects to have an Intel x86 processor, and it expects to live withing windows. Android is aimed at different processors.
I don't know Android much, but there must be Virtrual Machines, and maybe one that looks like an x86 with standard PC peripherals, but by now we are upto our armpits in angry alligators...

Simple is cool!

For cool, see this, using the bluetooth capability of the phone to connect to the old HK transmitter via blutooth RS232 interface.

Look Ma, no cables
