Intercom and Isadora

I am trying to connect a video intercom to Isadora.

I got a really fancy video intercom which costed like $130 on ebay which came with a SONY CCD.

I figure out that this video intercom uses regular composite video signal.

So I bought Easycap - video capturing hardware and connect intercom's camera to it.

You actually need 12v adopter to supply power to the cam.

Connect the center pin of composite wire to video wire of the cam(in this case white).

Connect black ground wire to composite wire and power supplier.

Connect 12V to red wire of cam.

It is easy.

Connect the other side of composite wire to Easycap.

Download the latest version of quick time and Isadora.

You need to go to Pre-Releases of Isadora's webpage and download Isadora v1.3.0f24 for Windows. The regular stable version did not work for my environment.

Go to Live capture Setting>Video Input

Device : USB2.0 Grabber.

Resolution : Half Size

Click Settings>NTSC/M

This webpage tells you more detail but it shows slightly different configuration with mine.

At least if you mess around the setup, you can find:-)

Additional Info

I realized that latest version of Isadora v1.3.0f24 for Windows does not work well if you run Windows 7 64 bit. I found an older version. It's seems fine. Not so much stable but better than not working..

Arduino UNO Assembly

I got an Arduino UNO Assembly from ebay.

To install

Connect Arduino Uno

Open the Device Manager(Windows User) . select the device that is indicated as unknown device(sometime it appears as Arduino Uno but not works properly I guess).

Double click it. in the new window go to Driver tab.

Renew Driver>manually search the driver.

Select the folder which your Arduino software install and chose the driver folder.

A new window may open and may warn you but continue to install.

Wait while. it may take like a minute.

*IMPORTANT

you should have the latest version of the Arduino Software. I had version 0018 it did not work, of course.

However I realized that if you have a GPS shield and not familiar with how to use. It is nice to have Arduino Software Version 0022. The program for GPS provided by sparkfun did not work for the latest version of Arduino Software. I did not check why, yet. I do not have a time now.

This is a great tutorial for arduino GPS shield.

Reference for XBee

The price of XBee Explorer Dongle is too expensive. $24

If you have a FTDI Basic Breakout($14) you can use it as a replacement. You can save $10.

To connect FTDI and XBee for PuTTY.

Connect

GND-GND

3.3V-VCC

TXO-DIN

TRI-DOUT

In the PuTTY terminal

type +++ without ENTER

XBee will return

OK
