How About a DIY project for that lazy weekend !!

Recently we had our vacations , which was filled with plans to do things that i always wanted to do but didn’t get the time. Among the list of things there was a very interesting DIY (Do It Yourself) project to make a GSM SIM (Subscriber Identity Module) card reader. Its pretty thrilling and quite easy to accomplish also !! I came across this project on Youtube, the last place according to me to find such stuff.

Well this project is from the site http://www.citizenengineer.com/ these guys have done quite a good job and the resources such as the circuit diagram and the necessary software are readily available. And for those of you who hail from Bangalore , the components are easily available from SP Road and should cost around Rs34/- without the SIM-card holder which itself costed me Rs30/- anyways the links are as follows:

1. The Project Home Page

2.The Schematics PNG EagleCAD file and EagleCAD board layout

3.Software Source Windows executable

Finally Some Pics of my SIM READER 🙂

  3. Hi Kunal,

    its nice to see that u have a working prototype… i have develped the same board but unfortunately the exe version of pysim reader doesnot list any ports on my machine… i have tested all my com ports succesfully with serial port terminal softwares.. it wrkin fine…….

    any suggestions to make it work..

    i use win 7 ultimate 32 bit.
    i have installed python 3 as well as python serial
    i am using the pysim reader msi installation file for windows……….
    circuit is well checked no issues

    • Hi Jagan,
      From your software list, i see that you are using python 3 , pysim reader is designed to use python 2.x
      can you try using that ?
      Also at the time of writing the blog , i did not have it fully working.
      Will try again using pyGSM , pySerial.
      You could try the same and let me know how it goes,

      regards,
      Kunal

      • hey kunal thnkz for the reply man………..

        also try another sim reader app called simscan v1.0 or 2.0

        i guess it was also sme issue with my board tooo.
        Appreciate that u replied….

        keep trying new things

        Bye 🙂
