  • Very Nice!

    What kind of motor do you use?

    It seems very silent.

  • @TechniekOnline. It's a standard DC fan similar to the ones you find inside PCs. It's not the motor that makes the noise in propeller clocks but the sound of the rotating clock cuting throught the air. Above 25Hz the whooshing sound is very noticeable in a quiet room.

  • @IDKJustRandomStuff u start thinking which part of the finger goes on first :)

  • whaat happens when you put your finger in it to wind it up............

  • do you sell this 1?

  • Great size and stability.

    But your rev/sec meter is biased by +0.1.

  • Felicitaciones, creo que es un excelente trabajo.
