Lego working clock : prototype 1

This is a working 3-hand clock with weight.

Autonomy is 15min but the aim is to create a working 12hrs autonomy clock. I must change where is the winch and the gear between the winch and the second hand. But this is a temperamental machine, when I change weight, period is changed, and when I change lenght of pendulum, weight must be ajusted. The difficulty is to find an harmony, therefore WIP !

WIP, any question please comment.

I only recently learned that the period of a pendulum is not affected by its amplitude. I now understand why pendulums are used in clocks. THANK YOU SCIENCE!

@LaggasaurusRex It is true, but only if the clock doesn't force the pendulum. In some cases, the system forces the period in order to find an unstable balance.

Have you placed the plans for this clock up somewhere? I would really like to build to to teach my students about simple machines.

[nico71240]

@Mrsleahtaylor Hum no but you can fo to my website or un brickshelf and find intresting pictures which allow you to re-built. I hope that it will be sufficient. If not, go to my website and look for 'cuckoo clock' and build the clock. I have made step by step the building instructions for the mechanism without the cuckoo. But it is a horyzontal pendular, not vertical. is it ok for you ?

can I get the plans for this clock, my little boy would like to build it.

@ThomasBarnard1972 Hello, I have considered your remark, I will release the building instruction as soon as possible. regards

Really nice piece of work - well done!

too fast.

I just want to ask you for the plans of the clock. Great work. I want to model it in Lego Digital Designer:)
