KNEX Clock

The operation of a click made out of K'NEX. It runs on only weights (pennies) and a pendulum. This video shows the anchor (the wiggling thing attached to the pendulum) which allows the escapement to advance one notch every "second" (at this stage, the clock had not yet been calibrated to keep accurate time)

thanks for all the comments! to answer you, wessellonus, the pendulum is kept swinging in the same way that a real grandfather clock's pendulum is kept swinging. there is a weight (in this case, a few rolls of pennies) attached to a string which is wound many times around the "escapement" axle (the rotating thing that looks like the spokes of a wheel - this is where the clock's face would eventually be). that keeps the escapement spinning, but it is stopped by the anchor every tick.

What a bulky escapement!

try making the bob shorter or lighter to make the "seconds" shorter

what dous it do? exact every second clicks?

[wessellonus]

I tried to make one myself BUT what does keep the pendule swinging? mine always stops after a while

even if it was not accutate and had a duration of spining (maybe 2 min per rotation like) and constantly went at that speed, it would still be useful to tell how long something takes.
