  1. dear sir/madam

    I am so interested to this ic tester, so please let me know the completed wiring, use direction when testing and also how to know testing result.

    Best regards
    agus

  2. As i have interest on this project for my major projects.
    so can you plez send me the codes with circuit diagram.

    with best regards
    anil

  8. dear sir,i m an service engg.the project very usefull for field service.pl send details where i recive the project kit at indian price.i m alok from india.west-bengal,kharagpur.ph no-+91-9046197220.waiting your valuable answer.thanks.

  9. sir my group trying to done the project of ic tester . will u plz tell us in which software u should done the programming ……………..plz sir we badl need the help…..

  10. sie i need the hex file for the coding of master and slave microcontroleers please…. send it…….urgent……

  11. I am a student of Electrical Engineering . I have studied and chosen this project as my final year project, I am keenly interested in it. sir I am stuck with the circuit diagram. What I need is the following:
    1)Complete description on how we can interface keyboard and indicator to the 8951 microcontroller
    2) Is this keyboard different from the keyboard of computer, if yes How can I design it?
    3)You have said that this digital IC tester is used to test any ICs and to test a particular digital IC, one needs to insert the IC into the IC socket and enter the IC number using the keyboard and then press the “ENTER” key. The IC number gets displayed in the 7-segment display unit.Here, what part of the IC is tested? please, verify it for me.
    4)Regarding to the above comments I wrote I need your response as early as possible (to mean your reply for what I have asked must be in a short period of time).
    You can send me all the necessary information via my e-mail
    my e-mail is:rockingsunnyrocking@gmail.com
    Thank you!

  12. please sir, i need a complete write up of the proceedure of constructing this microcontroler logic gate tester kit.

  13. hai sir…could u please tell me d components required or just how much it cost to implement d circuit…

  14. sir,
    I ve selected ur project as my mini project
    I have some doubts
    you have clearly explained how master IC sends info(IC number) to the slave
    but how does slave responses to the master

  15. is it possible for us to know if an ic is good or bad using dis tester…??or can v just distinguish btw analog n digital ic…??

  16. On the 8951 IC tester how can you test a 24 pin IC when only 20 pins of the test socket are connected, pins 11,12,13,14 are open.
    when the master program and the slave program are compiled to a hex using MCU8051 IDE errors are generated and compiling is unsuccessful, these errors are ,
    ‘Compiling file: Test1.asm (Master)
    Initializing pre-processor …
    Warning at 0 in Test1.asm: Missing `END’ directive
    Syntax error at 64 in Test1.asm: Invalid set of operands: mov @R0,R1

    Pre-processing FAILED !

    3 errors, 2 warnings’
    These are the listings of the errors of both files.
    Can you explain why.

  17. Dear if anyone has the correct code for ic tester plz send me…as early as possible i hv to submit my project …given code does not creates hex file …
    send me this at ..

    ranajuni541@yahoo.com

  18. Hello Sir….
    My final year project is a “Digital IC Tester”. please send me project report and details for programming…..

  19. awesome circuit. Well i see all people asking for some or the other help for the circuit design or pcb or the code. people try it doing yourself why depend on others, when the author who has presented it could do means it has to be possible to do it yourself right?? .be independent

  20. i am stuck with the code for ic tester. please send me the code as soon as possible as i have to submit my project in the mid of february….

  21. Hello sir…
    My project is a ” Digital Ic Tester” please send me project report & details for programming……

  22. hello sir
    my topic is ‘digital ic tester’
    sir can u send me the complete circuit diagram of this project and the coding part…
    its really important..
    if u can, please do…

  23. Plzzzzz send me hex file of this program cause recent program nt convert in hex file plzz tommoro I have a submission

  24. I have been browsing online moore than three houirs today, yet
    I never found any interesting article like yours.
    It’s pretty worth enough for me. In my view, if all site owners and bloggers made
    gopd content aas you did, the internet will be much
    more useful than ever before.

  25. Hello just wanted to give youu a quick heads up. The words iin your post seem to be running off the screen in Internet explorer.
    I’m not sure if this is a formatting issue or something to do with web browser compatibility but I figured I’d post
    to let you know. The design look great though!
    Hope you get the issuue resolved soon. Kudos

  26. I ssimply couldn’t despart your site prior to suggesting that
    I really loved the usual inffo an individual supply on your visitors?
    Is gonna be again steadily in order to inspect new posts

  27. hello sir..can i get the schematic, pcb layout and coding…i’m doing this project for final year.
