Pendulum Wave Music Machine 2 (aka the Pangolin) - with explanation

[aeh5040]

Hi all,

I made a larger (2-octave) version of this, together with a second video explaining how it works:

Absolutely brilliant as always! I love the way you have arranged the diffs, very clever:)

Fantastic - a musical version of your Synchro Pods! I love these sort of creations - using the real 'technical' aspect of Technic!

I was surprised to see the clutch gears at first because I thought jams would be unlikely, but that any slippage would make keeping the strikers in time a nightmare. But it then occurred to me that you'd probably use them to synchronise the machine in the first place - and you explained that in the second video.

So what sensory version are you going to work on next after visual and audible?  Or are you just working your way up to a full recreation of Babbage's Difference Engine?

Thanks!  A babbage difference engine has been done:

I'd love to replicate that, but I don't know how!

A harmonic analyser might be fun (and the differential mechanism here could be part of it...)

The harmonic analyzer is what I want to tackle next. I find it incredibly clever - the result of Michelson understanding Fourier analysis very well. The videos are super detailed, but I did think that one part of the machine relied on amplifying very fine movements, which would be an issue with LEGO, I think.

Babbage's difference machine I would love to replicate, but I find it very daunting.

@aeh5040What about a workshop thread where you collect all your masterpieces? sometimes brilliant inventions just get lost in the background noise of the contributions. Along with the inspiration that a work often conveys only as a whole.

...Yes you can argue to use the search function i know. https://www.eurobricks.com/forum/index.php?/profile/14345-aeh5040/&do=content&type=forums_topic&change_section=1

I would answer: The individual is not just the sum of its parts.

By the way I love the Pangolin it reminds me of the work of Steve Reich.

Best wishes

Thank you for the kind remarks and the suggestion. I'll look into that. Sometimes I find I miss things when they are in such a thread, though, because I don't realise there is a new model. Perhaps the solution is to have a general thread and also one for each model, but perhaps that is too much duplication?
