GIVEAWAY: The Whistled, a sound controlled relay

Posted on Wednesday, December 4th, 2013 in contest by DP


Mathieu Stephan over at Limpkin wants to giveaway three whistled platforms (assembled PCB).  The whistled allows you to control one device by simply whistling two musical notes.

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

For more information visit the project’s site -Limpkin.   It’s also up on Tindie.

    sweet tune :-)

  2. George says:

    Would love one for my automation project.
    But.. never won anything.

  3. Futari Media says:

    Christmas may come early?

  4. byutea says:

    here we come ;)

  5. Paco says:

    Cool idea, it will be very nice to use it to open the fence door.

  6. Chris says:

    Nice, thanks,

  7. Tom Price says:

    Sounds fun.

  8. Andy S says:

    Sounds fun to play with.

  9. Fryco says:

    Amazing work!

  10. Geoff says:

    So I can whistle the dog and have the door unlock for her too? Genius.

  11. Gregy says:

    Wow, would use it for dorm lights :)

  12. Dan Ringer says:


  13. Paulius says:

    Amazing thing! I would really find good use for it :)

  14. britesc says:

    Really nice gesture.
    Good luck to all.

  15. Scott says:

    heh, that’s pretty cool!

    Hi to the DangerousPrototypes team,

    That’s would be the perfect tool for driving the lights of my “always-forgetting-to-switch-off-the-light-in-theirs-rooms” children… That’s is funny , I’m sure they will love it …

    Great work !!!

    Thank you very much

    Good Luck to everybody

  17. Tiziano says:

    Great project!

  18. Kevin Groce says:

    This would be a great for a dog treat launcher. :D

  19. Jörn says:

    Nice tool, World bei perfekt for sich

  20. Jörn says:

    Nice tool, would be perfect for switching or dimming LED strips.

  21. Brad says:

    Man, I’ve been curious about this one for a whole. Love to play around with the fft processing.

  22. John says:

    I would love to play with one of these. FFT on a Cortex M4 – Awesome!
    I would hack it to use rgb strips. :) Controlling a additional board trough i2c or uart would bei fun to.

  23. collin says:

    That’s really cool

  24. Sai Yamanoor says:

    Nifty gadget

  25. Oooh, I could hook this up to my daughter’s night light.

  26. Daniel Del Mul says:

    Love to try it.

  27. udif says:

    Hope I win!

  28. mircho says:

    I like his hackaday contributions

  29. Jelmer says:

    I’ll make a nice review!

  30. pspgeek says:

    very interesting

  31. Ross says:

    This thing looks great! I might even have time to play with it over the winter holiday.

  32. Coyt says:

    Cool! I’m thinking a failsafe for backing up important data files (I.E. bitcoin) if something happened… police preak down door and have you in cuffs for some reason or another… you wistle… all incriminating documents / money get backed up remotely and then deleted >:)

  34. DPS says:

    Nice work and attention to detail!

    /roll 3d6: 3! Critical success! :-)

  35. Pieter says:

    Funny and interesting

  36. Gabor says:

    Adding a bluetooth module makes sure to everyone thinking you are stupid when you try to whistle-skip the track you are listening.:D
    Challange accepted.

  37. ken says:

    can it respond to claps as well? Clap on…clap off :-)

  38. gecko says:

    really interesting!!!

  39. Mac Ha says:

    Hm, would it respond to an ultrasound whistle!?

  40. netrafter says:

    I would like to whistle into this stuff.
    Thankfully from India

  41. Grubi says:

    Will be more fun with melody recognition…

  42. RichF says:

    Too would be a cool way for me to turn on the computer hat is connected to the HDTV.

  43. Chad says:

    I’d love one! Sounds like a lot of fun.

  44. octavio says:

    Cool board! Love the M4 core.

  45. mk2soldier says:

    Thank you!

  46. vitya says:

    This is the winning entry! :)

  48. Piotr says:

    Dear Santa Claus…

  49. Kunal Ghosh says:

    My Random comment !

  50. Mark28 says:

    One for me

  51. EschatologicalEngineer says:

    Interesting Design!

  52. Dean says:

    I’ve done some tone recognition stuff in the past – not as easy as it sounds. Good job, and cool product!

  53. Prasinos says:

    Cool and well made!

  54. Adnc says:

    One more…

  55. Alecs says:

    Nice project!

  56. Sasa says:

    It sounds fun :D

  57. Romek says:

    I would like one

  58. Bryan says:

    Looks fun!

  59. Rasz says:

    very nice use of DSP, good board to get started with signal processing.

  60. Kevin says:

  61. RadioOne says:

    That’s christmas before christmas …
    Let’s cross fingers
    See you & thank you for the challenge

  62. Aleks says:

    Well… let’s see if this will win me something :-)

  63. Nathan says:

    This could make for some fun color changing led lights

  64. mh says:

    very nice, could use one.

  65. Matt says:

    I would love one of these :D

  66. Matt says:

    Nice, that could really be handy

  67. Steve Robillard says:

    I may have to learn to whistle a second note – though i wonder how I can incorporate my dog (the usual reason to whistle) with this device – maybe an automated ball chucker.

  68. Tim says:

    Very cool!

  69. Manuel Garbe says:

    This is my random comment

  70. Bruce Gentle says:

    I’ll just wjistle while I wait

  71. Carl Hage says:

    Cool! I wonder how much power is consumed to scan for whistles? Could it be reduced by some sort of threshhold volume or other method to sleep most of the time and then wake to determine if full FFT is needed?

  72. John Tarbox says:

    Would love to win, and that ain’t just whistling Dixie ;-)

  73. grey says:

    I like Coyt’ comment above of using a system like this as a failsafe to prevent sensitive data from being stolen, but unless it involved remote activation of degaussers or to poweroff systems that require passwords, don’t really see any benefit over a program that runs resident on a PC. I wonder how handy it come be for security applications in case of emergencies. I also wonder what happens if a bird decides to land near a window or if a somebody whistles on tv/radio/video/teapot and if there would be a way to filter out human versus speaker /bird whistles.

  74. Marius says:


  75. FourthDr says:

    Whistle ON!, Whistle OFF! Whistle on whistle off THE WHISTLER!! :-D Sound familiar?

  76. XTL says:

    Very interesting. It’s nice to see an open design based on this chip.

  77. Dennis says:

    Great – would love to hear it in action…

  78. mrbbp says:

    love this project.

  79. William says:

    Maybe this will finally get me to learn to whistle.

  80. Lahcen says:

    I would love to use it to turn off/on the light in my room.

  81. mol-1 says:

    Would be genius to get one, I didn’t won anything ….

  82. j says:

    hey hope to get a whistled, thanks for the giveaway

  83. Samual says:

    I can whistle and control the light in my room that’s better than my existing IR remote control system. Hope I get one.

  84. Robert Thille says:

    One of those would be awesome. I’d love it for opening/closing the garage door from the outside…
