I was able to receive the following images from NOAA 19 satellite. the frequency is 137.100 Mhz.
and you can use WxtoImg software to decode the pictures.

Control your old fan.....From a SONY tv remote

It's really nice when you have the control of your fan in your hands....specially in a cold morning..that you do not like to getup form the bed. I will post the details of the schematic later. but its nothing much just replace your regular fan switch with 2/3 relays.
give the relay control to the Arduino board. I have connected 2 relays to the pins 5 and 7 of the Arduino board. and pin 4 for a buzzer. attach the IR sensor head to Pin 11
include IRremote library with the code

Controlling your Scanner over the Internet

if you want to control your scanner over the internet & if it doesn't have any serial port to control, then this is for you.
Things you need
1. one Arduino board (for the Ethernet Shield)
2. one Ardino board for the scanner interface
3. IIS server running on Windows 7 with PHP
4. PHP interface
5  Port forwarding knowledge
6. Audio streaming server 

we have to use some sort of power saving to control the PC running the servers. and we should be able to boot up the PC remotely. that's why we have to use  one Arduino with Ethernet shield for this purpose.

first we have to install the IIS server in windows 7 with PHP.

First of all, you need PHP (obviously). Go to the PHP download page and grab the latest non-thread-safe ZIP archive for Windows. As of writing this, the package is called "PHP 5.2.8 Non-thread-safe zip package". Unzip the archive to a folder on your hard disk (I use C:\php5) and create a copy of php.ini-recommended (or php.ini-production in recent PHP versions) called php.ini. There, add the following configuration setting:

cgi.force_redirect = 0

This is the minimum setting you need to change to make PHP work with IIS. You may also want to use cgi.fix_pathinfo = 1, fastcgi.impersonate = 1, and set extension_dir appropriately.

Then it's time to install IIS. You need at least the "Business" version of Windows 7, but the currently available beta 1 is Windows 7 Ultimate anyway. Go to Start/Control Panel/Programs/Turn Windows Features on or off and check on the Internet Information Services entry. Activate the World Wide Web Services/Application Development Features/CGI node and also Web Management Tools/IIS Management Console (the latter not shown in the figure).

Now, start the IIS Management Console; just open up the start menu, enter inetmgr and hit Enter. There, navigate to the Sites/Default Web Site/Handler Mappings node and double-click on the "Handler Mappings" entry.

As a result of this, the Actions panel on the right hand side changes. You now see an option called Add Module Mapping. Clicking on it opens up a dialog which you fill out as you can see in the following figure (you may need to adapt the path used to your local system).

If you do not see the FastCgiModule entry, you probably forgot to check the CGI node when installing IIS. Otherwise, close the Add Module Mapping dialog by clicking on OK. You need to confirm that you want to create a FastCGI application; click Yes.

Finally, create a .php script and put it in the root folder of the IIS site (by default C:\Inetpub\wwwroot; note that you may need additional rights to write into that directory), e.g. phpinfo.php with a simple phpinfo() call in it. Call this script using http://localhost/phpinfo.php, and you are done!

Put following code in phpinfo.php file

and finally since you are going to control this over the internet you need to bind your PHP web page with the port that you are going to forward. to do that go to controlpanel<<administrative tools<<IIS manager. on the left pane expand site and click bindings on right pane.Enter the port and IP of  the PC you are forwarding

To be Continued............

Spying on cordless phones

Most of the people in my neighborhood still using pretty old stuff. its very easy to capture the audio if you tune into one of these frequencies.

46.610 MHz
46.630 MHz
46.670 MHz
46.710 MHz
46.730 MHz
46.770 MHz
46.830 MHz
46.870 MHz
46.930 MHz
46.970 MHz

streaming your scanner

i was trying to find a way to stream my scanner audio feed for 2 days. finally found a simple way.

• first forward your port of the router (use the ip of the pc that you are running the media server on)
• download broadwave audio streaming software
• select the line in and connect your scanner

it's better to assign a domain name by using  http://www.no-ip.com/ so that they will track your ip.

 

here is no ip settings. port number is the port used by broadwave software
