Hey everyone, Jason here
today I'm going to show you this custom LEGO model I've built of a hand playing a piano
It's currently being
operated by this nine volt motor
which I'll take off for now
when the motors isn't attached
it can be operated manually using the crank on the side
so let's take a closer look at what's going on here
we'll start with the hand
as you can see each finger
is attached to a LEGO technic beam
which is connected to a crank shaft that runs through the base of the stand
and as you turn the crank
the fingers move up and down
next we'll take a look at the piano section
which is quite reasonably scaled
and all the keys move up and down including the black ones
the action's actually reasonably accurate
especially considering it's all constructed out of LEGO eventually I may add
some sensors and electronics to produce sound
but at the moment it just makes beautiful LEGO music
I have a little model here to show you how the keys work
there is a technic axle that runs through the back that all the white keys
pivot on
also one that all the black keys pivot on
each of the keys just rests on one of these technic springs
and underneath each one is also a
LEGO rubber tire to provide some dampening
and when you put it all together
it's actually quite simple
I guess that's about it
be sure to check out some of the other videos
on my channel
and if you'd like to see
photos of this model or all of the LEGO models that I've made you can check out my
photo stream on flickr
you can also find instructions for many of the models I've built on my website
and also be sure to check out
my marble maze project on LEGO CUUSOO
and support it if you like it

thanks for watching, I hope you enjoyed it
see you next time
