Giveaway: TraId kits – Transistor type & pinout identifier

Posted on Friday, September 6th, 2013 in contest, PCBs by DP


Mats has amazed us with his board a week projects, and now one of them could be yours!  Today Mats is giving away three TraId kits – Transistor type & pinout identifier.  All parts included except for a CR2032 battery that needs to be sourced locally due to postage regulations:

TraId is a really low cost version of the Part Ninja. It’s made to only identify the pinout and type (NPN/PNP) of a transistor and display the results on eight LEDs. Currently the firmware only handles BJTs but I think FETs should be possible as well.

He’ll give these away to 3 random commenters, just leave a comment on this post.

Firmware and other files can be found on Github.  For more information visit the project’s Tindie site.

    Will come in handy for transistor applications

  2. Rob says:

    What a great circuit! Very clever!

  3. PiXEL8 says:

    This is rad, please pick me I could use one of these. Thanks!

  4. Jack Wilson says:

    I’m in!

  5. Cedric Perron says:

    Nice Project!

    They should ask students to make this kind of project in college.

    Good way to learn more about analog and digital electronic.

  6. Noy says:

    Hell ya! Hopefully better than my Hameg 205 Component Tester!

  7. Brad Voth says:

    Looks awesome! So could use one of these.

  8. DanielBuentello says:

    This is awesome. Looking forward to a FeT version

  9. Joshua Noble says:

    I’m too late :(

  10. Nik says:

    This is pretty cool.

  11. Kyle Hamilton says:

    This looks like a great piece of kit! Def count me in.

  12. Chankster says:

    Mats, awesome job as always! Thanks for giving away so many neat projects.

  13. utox says:

    will be helpful!

  14. pspgeek says:

    good job!

  15. Cody says:

    Nice work mate

  16. William says:

    I so could use this!

  17. Matthew Gingerich says:

    I would love one of these for building motor control circuits

  18. Bruce says:

    Great to identify the leads of all of those old transistor sitting in the drawer

  19. Chris says:

    What a neat idea. I wish I had the time, skill and imagination to create a new project every week!

  20. Eyeball Kirkenbach says:

    Hell yeah! Matt’s stuff is great. Go to Tindie. Buy it all.

  21. James says:

    Always using a meter to find out what I’ve got in the scrounge bin, this would be ultra-helpful!

  22. Zdravko says:

    Great little board!

  23. I’ve got a bunch of transistors that fell out of their containers in my old hobby box. This would help me sort them out!

  24. Those board are great inspiration for me. Thanks for making them.

  25. Rob says:

    I would like to have one :)

  26. Adam says:

    This PCB a week series has been pretty fantastic.

  27. project2501x says:

    Me! :)

  28. Mac Ha says:

    Would be very handy – is it open source, can you share the code for the diy?

  29. Chris says:

    neat idea

  30. bjorn says:

    Very handy on the workbench!

  31. SaakNeMah says:


  32. superUnknown says:

    Yes! This will really help with getting the transistor bin organized!

  33. Paul says:

    This would make a sweet little project for my son, who’s just getting into electronics.

  34. Dan ringer says:

    Pick me looks awesome.

  35. Duselbaer says:

    Great Job! I think there’s some place for it on my desk :)

  36. John E says:

    Sounds awesome!

  37. Jim says:

    This is perfect for my student helpers to identify pin outs on a drawer full of transistors they use for breadboard projects. The transistor pin out is their biggest obstacle and they are always getting it wrong!

  38. J. Peterson says:

    I’d love to get one of these, and am happy to pay for it. Will it be up in the store soon?

  39. Ed says:

    Sounds Fun!

  40. Manuel Garbe says:

    maybe me :):)

  41. Scott Schiffmacher says:

    Can’t wait to try this!

  42. Paco says:

    One of this will be very handy…

  43. mikelelere says:

    Really nice tool! I would love having a look at the firmware…

  44. TanaH says:

    Looking forward to FET support ;)

  45. Yulka says:

    One here please ;)

  46. Rodrigo says:

    Uow! Here we go again!

  47. Marcello says:

    I am a random commenter……….. :-)

  48. mh says:

    Beats commenting on and not winning the sunday PCB. Not winning a TraId will just make my day!

  49. Baptiste says:

    I’m in, and WHAT? Am I a winner…? :)

  50. Jon says:

    Just what I need to check out my bag of transistors. I’ll be glad to take one.

  51. Nate says:

    This looks super useful. I would like one :)

  52. Axiom says:

    Great Idea!!

  53. I have a PILE of transistors that I would love to identify. Many are at least 20 years old and the markings are at best worn and at worst gone totally. This would be an awesome tool.

  54. Miriam says:

    Great tool to have on my bench if I’m the choosen one

  55. Bob R says:

    Most excellent!

  56. kmel says:

    yes, one for me, please.

  57. vmax says:

    Small hardware with big application must inform student

  58. Collin says:


  59. insurgent says:

    Cool project!

  60. DG says:

    Here’s my entry. :)

  61. Mac Bandit says:


  62. German-Freak says:

    Cool little project ! And its useful too ! Greeting from Germany :)

  63. wavo wig says:


  64. Sayan says:

    I would love to get one !

  65. Ketracel says:

    Cool! Can it detect the difference between mosfets and standard bipolar transistors?

    • Mats Engstrom (@matseng) says:

      I think it will be able to handle mosfets correctly, but I haven’t actually written any firmware for it yet. Hope to have it done before sending out the boards to the winners in a day or two.

  66. Syahir says:

    Pretty neat!

  67. That’s great one! Pick me!

  68. Art says:

    Cool kit, would love to have one. Good work Mats.

  69. Futari Media says:

    Nice piece of kit!

  70. Great , I like this ..

  71. Scanboostar says:

    Ahhh, now I can put those old transistors I have to good use!

  72. j says:

    pretty cool little device, hope i get it.


  73. netrafter says:

    Hey, That’s a good handy device. Hope to get one.

  74. Glaisin says:

    Nice! Takes the mystery out of the transistors in the “Mystery Bin!”

  75. Ross says:

    Great idea. I could really use one of these!

  76. Giuseppe says:

    Very nice project!!!

  77. Andrew says:

    very nice!

  78. Mark Moran says:

    Great idea. The LEDs are already labelled for FETs as well as BJTs, do they definitely work?

    • Well…. They work for low Vgs N-Channel FETs like 2n7000 and IRF540. I haven’t implemented P-channel yet in the firmware because I couldn’t find any in my parts bin.

      Since this is just a prototype and a test I labelled the PCB in the hopes that I might get FETs to work as well. It would be rather annoying to get it working and not have the labels :-)

  79. Skappy says:

    I would be very proud of getting one of these …
    Thank you very much
    Have a nice day

  80. BlassPetals says:

    Thanks for sharing the firmware source.

  81. bob says:

    looks like a handy tool to keep in the parts box..

  82. Brian Griffin says:

    Nice and simple project! Keep it up. :)

  83. JanneMM says:

    Now this is something that should be found in every hackers’ lab…

  84. vitya says:

    I hope I am not too late for this…
