Matrice 100 - On Board SDK - dji-sdk

For my M100 I want to control several external devices such as laserpointer or thermal camera. I think, for a full control I have to integrate it by OSDK. I looked through the dji sdk documentation, but I have no idea where to start and what I effectively have to do. May somebody give me a little hint how to start and what really is necessary to fullfill my requirement described below.
Connect a Flir Boson (3.3V) and display the thermal image on the remote controllers mobile device.
Control the thermal camera (switch on/off) by the remote conroller.
Connect a laser pointer on a standard port of the M100 and control switch it on/off by a button of the remote controller.

radio.garden volume not showing volume control in browser on microsoft surface

I don't know anywhere else to ask this. radio.garden is an aggregator of online streaming radio stations. In windows 10 on various machines, it shows a volume slider beside the play/pause controls. With the same version of firefox on windows 10, and still after upgrading to windows 11, the volume control doesn't show on microsoft surface. I have deleted display and audio drivers and let them update, and I have turned firefox hardware acceleration settings off (even though the settings indicates that it is only for graphics). I have also verified that microsoft edge also does not display the volume control.
What do I need to check next to figure out what's going on? I assume the browsers are using some api that perhaps I have blocked via privacy settings that aren't applicable on desktop or something, or maybe provided by some audio drivers and not others?

Mac OS: get full control of web-camera (USB connected)

The task:
OS: Mac OS X 10.9 +
Description:
There is web-camera connected to a Mac via USB. I need to discover a way of getting access to its' brightness, pan, color temperature, focus, etc.
I also need a way to apply image filters against camera's video stream.
I need to be able to control the camera while it is being used by other programs like Skype, so I can transmit for example video stream with increased contrast at Skype video call.
Reference app: https://itunes.apple.com/app/webcam-settings/id533696630?mt=12
Solution:
This is the question.
As far as I understood I must to find custom kext (driver) in order to perform all this magic.
Could you please show me right direction, libraries, drivers, etc.
You can use opencv library to capture camera frames, apply filters, etc.
http://docs.opencv.org/2.4/doc/tutorials/introduction/display_image/display_image.html
Then you can feed a virtual cam that can feed into Skype, etc.

There also many open source virtual webcam available.
I hope this helps.

Adding a third camera

As my company has a special need of installing a third camera on a Windows Phone Mango, do you think this is possible to access to the camera using Mango's Camera API?
As far as I can see the PhotoCamera only has two constructures: PhotoCamera() and PhotoCamera(CameraType type). The "type" here can only Primary or FrontFacing so I guess we cannot do anything else here.
We don't get this issue on Android, as they have the interface of Camera.open(int cameraId), and the cameraId can be any id between 0 and Camera.getNumberOfCameras() - 1.
I'm a bit confused, as there's no way to "install" another camera. There is no USB host port on the device, nor is there any other harcware interface, so how would you connect the camera physically?
Even if you could connect physically, there's no way for anyone other than a phone OEM to create and install the drivers for said camera, so how would the OS enumerate it to the platform?
If you're an OEM, you've undoubtedly got a support channel directly with Microsoft where you could ask this, as no one outside that channel is going to have any idea. If you're not an OEM, there's simply no way to add a camera or any other (non-bluetooth) peripheral to the phone.

How to get Pressure from a Tablet PC to be used with HTML5-Canvas

I want to draw with my Tablet PC (HP Elitebook) in a web page, and I want to create a "Paint" that I can use in a web browser, using HTML5-Canvas if possible.
I'm new to Tablet PC programming ... and I only found ways to manage stylus pressure with a Microsoft library or QT ... but it is not for webpages.
I also found that there is something for Wacom tablets ( http://www.wacomeng.com/web/index.html ) but it doesn't seems to work with my Tablet PC.
So how can I manage Tablet inputs in a website (and especialy get pressure) ?
And also, what are the most commun and well documented library (in C/C++/Java) for managing a Tablet PC ?
If you use the firefox 4 or later, you can get pressure value from DOM MouseEvent's "mozPressure" property.

I believe the stylus, which contains the pressure sensor, is made by Watcom in that unit. They would need to write a custom plugin to offer browser support for their device. Send them a mail!

Is it possible to create an Geotracking app in WP7 using Bing Maps?

Is it possible to create an app like Runtastic, RunKeeper or SportsTracker (all of them Android apps) in WP7 using Bing Maps? Or maybe there is an app with that functionality already out?
These apps basically trace the route you run/cycle/jogg/etc in Google maps, displaying your current speed, altitude, cal lost, direction, etc. Then they have an option for storing the tracks and displaying their related information later. They can display charts as well.
Also, what sensors does WP7 devices have?
The image below is runtastic, tracing the path as you go
Thanks
Yes it's possible. But you should get past the idea stage and into the development before posting questions here.
As for what sensors are available, you can find more information about the minimum hardware specifications here
A WP7 device must, at a minimum have the following:
Accelerometer with Compass
Assisted GPS
Ambient light Sensor
Proximity Sensor
Camera with LED flash
FM radio tuner
It is possible since you can translate existing GPS coordinates to the Bing Maps control. Must of the features Chris mentioned are not required for a geotracking application (those are general device requirements). All that's needed is basically the GPS sensor.
Note one important element - you will not be able to run the application as a background process. Although you can keep it under the lock screen, you will not be able to switch to other processes (only to a very limited extent and under specific conditions).
