Knock Clock

Knock Clock is a fun little 48-hour project by Gijs Huisman, Giorgio Uboldi, Michael-Owen Liston. I really like the clever photosensor “set alarm” switch. Nicely done!

  1. Brilliant!
    ‘nuf said.

  2. Nice idea, but room for improvement. I think if I had a go at it I’d use a solenoid rather than a noisy motor, that whirring is really annoying…

  3. Great idea. Love the look, it’s clearly very well made.
    Please get rid of the motor noise.
    Solenoid or a stepper motor would seem the way to go.

    When can I buy one ?

  4. Did anyone thought about colourblind peoples when creating this &"%&"%&-Resistor-Quiz???

  5. nice
