    Good job !

  3. Sk says:

    Mats needs a store. I wanna buy some of his stuff!

  4. pspgeek says:

    Very useful board.

  5. Harshad says:

    Let me try my luck if I can get this one it will be big relief while soldering !

    great work Mats ! Finger Crossed !!

  6. Michael says:

    Looks useful.

  7. Greg says:

    Yet another excellent giveaway

  8. Mutlu says:

    Looks like victorinox of leds

  9. dda says:

    Concur. A must have to preserve sanity!

  10. N'Gonka says:

    Maybe I’m the lucky one?!

  11. I was selected for a BB Prince board previously, but I didn’t see the email soon enough, and it was given to somebody else. Let’s try this again! I’ve got a bunch of old LEDs that came loose in my parts box. This would be great for quickly testing them and getting them organized again. :)

  12. Seth says:

    Sounds like a sweet little board.

  13. Jim Turpin says:

    This is so damned handy. I want one! :)

  14. William says:

    This would be so helpful!!!! I do a lot of SMD soldering. Save me so much time….

    Awesome idea!

  15. Patrick Friedel says:

    Since I plan on scaling up my 20 0603 charlieplex to 110 LEDs, this would make it a _hell_ of a lot easier to set up the LEDs that having to meter every. single. one. And cheaper than hacking up a vacuum pen!

  16. This looks really useful!

  17. Cool !!!
    I like this very much …Very helpful in the daily work … Bright idea !!!!!

    I’d love one. You can never have too many good test tools! Makes life so much easier.

  20. iuliia says:

    Cool project, it will be very handy to have one.

  23. Allen Brown says:

    what a great gadget. I want one!

  24. lebeno says:

    I really like the arrangement of the resistors. They are like centipedes or ants walking to the power.

  25. Dr. Obscure says:

    I could really use one of these.. I’m always failing to remember which end/lead is which.. have had to redo more than one in my working history :).. Now retired, I could use the free one !!

  26. Matthew Beckler says:

    This is a really handy board for the experimenter, nice work! I would like to win one.

  27. vmax says:

    random comment…….

  28. Rishabh says:

    Would be handy

  29. Jussi says:

    I could definitely use one.

  31. Arnd says:

    Great offer from Mats! And great idea as I’ve had trouble before with polarity of SMD LEDs…

  32. Maxigraf says:

    I’d like one :)

  33. dolabra says:

    Sweet. I could use one of those.!

  34. John Tarbox says:

    This could be the light of my lab ;-)

  35. mh says:

    this would make it up for never winning a pcb in free pcb sunday

  36. George says:

    Super Handy !!!

  37. Mac Ha says:

    Would love to get it, or make myself…

  38. SuperD says:

    That would be great to get one! Although I’ll admit if I don’t I’m going to be making one ;-)

  39. Ethan Zonca says:

    This would definitely be useful

  40. Hli says:

    It’s nice to see you going on again with the PAW project…

  41. Huy Do says:

    Just try my luck.

  42. Kunal says:

    Is there a script which randomly picks a comment or is it done manually ?

  43. Pick me! Pick me! Pick me!

  44. Brett says:

    well done Mats on a great series of devices

  45. collin says:

    Pick me!

    It’s not Sunday but what the heck…

    Once more into the breach.

  47. Josh says:

    very cool

    also, i love the board a week idea.

  48. ryan says:

    This would be great!

  49. Cris says:

    Man that would be awesome to play with

  50. Syahir says:

    Neat project.

  51. klim says:

    This’s truly a life saver for our production operators when they couldn’t figure out the type (CC/CA) and polarity of the LED.

  52. Scott says:

    Hey, what a cool idea!

  53. wavo wig says:


  54. Wolfi says:

    Simple is good.

  55. Simon says:

    Very handy little tool!

  56. xkltck says:

    Sounds practical! One here :)

  57. VikTak says:

    random random random :)

  58. DJPhil says:

    Wow. You really have a knack for thinking up useful stuff.

  59. Skappy says:

    Would be happy t get one …
    Thank you very much for this giveaway
    Have a nice day

  60. Prasinos says:

    Clever idea!

  61. jechavarria says:

    A great idea! One of this wil be very usefull in my work! Congratulations for the idea and the design

  62. Jon says:

    I would love one of these handy little testers!

  63. netrafter says:

    Looks cool, want one!

  64. Sleepwalker3 says:

    Yes another great idea, it would save trying to check it with your meter probes and ending up losing the LED half the time.

  65. Paul says:

    Very handy indeed; I might have to pick one up once they’re in the Tindie store. Those BBB LEDs sound like a real bummer, Mats – but hopefully you’ll sort them out in no time with one of these!

  66. MarkR says:

    I have an Altoids tin full of misc scavenged LEDs. This would be a life saver. Sorting out single LEDs is simple enough, but the multi-leaded and/or multi-colored are a pain with just a DVM.

  67. Mountsindude says:

    Would love one!
    I’ve also probed LEDs with the multimeter lots of times…
