Long time ago, when I was doing lots of demos and used to have to display mobile phone like smartphone of Windows Embedded devices, I needed a mobile video recorder to be able to display them. Of course, I though using a webcam but the webcam alone does not allow you to demo the device. And I figure out that those kind of animation stand costs lots of money and were not easy to transport and very costly to rent. So I decided to build my own. And I recently use it again as I had to demo my Windows Phone 7 device and also .NET Microframework device like netduino.
The main features I needed were:
So I came to the following solution:
Everything can be unplugged and transported easily. It is using a webcam and simple plastic pipes. It costs only couple of euros ($ for our non European friends ) to build. On the software side, I used a DirectX sample which I customize to create my own application.
And I sued this solution very recently during the French TechDays where I did a demo of .NET Microframework. The equipment in place was not working and I was glad to have my own mobile video recorder with me So, I use it as you’ll be able to see when the video will be available.
so let start with the hardware part. what you’ll need:
Now to build it, you’ll need to cut the following parts:
And here is the technical schema (forget about the webcam yet):
With this you can basically adapt any camera. You may recognize on this picture an old Philips webcam and on the one I pick recently a nice Microsoft LifeCam Cinema. A perfect HD camera with some good feature to tune the brightness. Also, it is very easy to install the camera on the pipes.
Step 1: glue assembly
Step 2: soft assemblies
On the software side, I’m using a simplified version of the DirectX SDK AMCAP example. You can easily select the webcam you want (if you have an integrated webcam and the external one, make it easy to choose) and setup the settings in the capture filter like the autofocus, the resolution, etc.
If you want this software let me know and write me at firstname.lastname@example.org.
I hope you’ve enjoy this tutorial to create hardware which is not electronic this time
Can the software and webcam work on Mac? If not, what do you recommend?
