Motion Detection with PhidgetSBC2 and Motion Sensor

This is a simple Phidgets project and want to show you that how  simple to write a program to detect a motion with a motion sensor with PhidgetSBC2 board. After motion detection two red LEDs set to on. So you can see the how analog input and digital outputs can be controlled with Java.

As you know PhidgetSBC2 is a single board computer and has 8 analog inputs, 8 digital inputs and 8 digital outputs on it.

Solution – Exception in thread “main” PhidgetException 5 (Phidget not physically attached.)

I have a PhidgetSBC board and wanted to open a connection to Phidget InterfaceKit 8/8/8 to listen a motion sensor which connected the first analog input on the board. There are some methods to connect interfacekit and listen the sensor.

A simple java code to connect interfacekit and read the kit name and print it.

If you try to connect with openAny() method , you can not open a connection to SBC, you should not use openAny() method for PhidgetSBC card.

“Version Mismatch webservice 1.0.8, expecting 1.0.9″ problem solution for PhidgetSBC

When you connect your Phidget SBC and click Phidget Interface 8/8/8 link under WebService->Bonjour Tab from Phidget Control Panel,  if an error message occured as following picture, please apply following steps to fix it,

Güzel konuşmaları ile güzel anlar yaşadık.

Handle an object as variable in a loop with programatically, VB.Net

If you have lots of textboxes or other objects in your project and you need to populate and control these objects programatically, use Controls property of form object to handle this.

An example,

        While sa.Read

            s = s + 1

            Me.Controls(“e” & s).Text = sa.Item(1)
            Me.Controls(“b” & s).Text = sa.Item(2)
            Me.Controls(“x” & s).Text = sa.Item(3)
            Me.Controls(“y” & s).Text = sa.Item(4)

        End While

The names of textboxes created in the loop and then the values which is stored in the DB assigned textboxes’ .text properties.

Image overlaying on a video file with FFMpeg

To add a logo/image  on a video file you need FFMpeg with vhook lib. New versions of FFMpeg cut the support for this lib. So you should find older FFMpeg versions with vhook DLL files. There are two DLL files under vhook directory which can be used for image overlaying. Watermark.dll and Imlib2.dll.

The below command can be run on CMD or CLI,

ffmpeg -i son.flv -vhook “imlib2.dll -x 10 -y 10 -i arge.png”  b1.flv

The arge.png file will be cordinated with x and y values on video. The son.flv video file will be converted wiht image overlaying to b1.flv vide file.

Thanks.

Changing FPS rate of a video with FFMPEG

If you want to change frame per second (fps) rate of a video file, you need a codec to achieve that. We can use FFMpeg to change this rate. You can run below script via CMD on windows or CLI on Linux.

 

ffmpeg -r 10 -f image2 -i C:\test\captures\image%d.png  C:\test\captures\test2.flv

A point to keep it mind that,

-r 10   : define new fps rate

image2 : image file format

C:\5d\captures\image%d.png : image files in a directory which will be converted a video

C:\5d\captures\test2.flv : destination file name

 

If you have any problem of this script please share it with a comment.
