welcome to another episode of intellect
on Wednesdays and here it is business as
usual as you can see I am trying out yet
another lifting mechanism it's a
comparable ratchet system combined
that's basically the slow more rolling
[Music]
in the last week's video I built a
ratchet marble lifting system and in
that video I said this instead I came up
with this a ratchet lifting system this
system really had the ability to lift
eight marbles per crank turn that was
all wrong that ratchet system and the
way it's driven only lifts for marbles
per crank turn and in this episode I'm
going to replace it with something
better than a mouthful to explain why we
need eight
[Music]
I thought I start with explaining why we
need to lift eight marbles per crank
turn you remember this test music I made
to explain the magnet MIDI music system
just to repeat every click here is one
crank turn turn turn turn turn right so
if we have a busy pattern on the
vibraphone like this you can already see
that we have one two three four notes
that means that we need four marbles per
crank turn to only to play this but the
more machine X has more instruments in
the vibraphone so if we add a simple
snare of be like that we're up to nine
marbles per to crank turns if so and if
we then continue add a simple kick drum
[Music]
and then we add Hyatt on top of that you
start to see here now seven marbles
product seven six seven but this pattern
is really simple if you make more
complicated kick drum pattern you see
we're already up to eight marbles per
factor
so this is drums and bar before girls
have to face so with a very busy
vibraphone pattern we exceed eight
marbles per crank John here we have four
seven and eleven marbles per crank turn
so the marble machine would we'll be
able to play this for some time because
it has a lot of marbles stored upstairs
but it won't be able to sustain it for
five minutes when I make a really busy
vibraphone pattern I need to keep the
drum pattern a little bit less busy
[Music]
yes coffee what would we do without
coffee so as you can see if we only had
four marbles for a crank time we would
only be able to play either only this or
like only this or only this but if we
can get eight marbles per crank turn we
will be able to play almost something
like this
so that's why it's so important okay
let's do some prototyping to solve this
problem I started with some spring
cleaning on my workshop and I built a
weld card slash Robo wars contestant the
draw for a sardar thought was a little
bit tough his meeting this old tony's
welding art in round one so we'll see
what i have to measure with this
prototype is the time for the marbles
needs going there because this will move
extremely fast
[Music]
so this is the improved prototype with
some changes and see if we can get up to
marble speed with that I have a slow-mo
camera set up the only thing I need now
is the marbles so let's go over here and
look and of course the one box I need is
guarded by a demon I love animal but
these long leg things have to convince
it that this is the wrong box to sit on
hello my friend can I please take my
marble whoa okay he went that good
[Music]
this one up
[Music]
17 divided on 25 0.68 four strokes
divided on 0.68 seconds equals five
point eight miles per second times 16
this was 352 BPM actually that's a nice
Headroom yay this proves that the
marbles loads fast enough in this method
for playing music up to 200 bpm
and in the prototype I'm using one row
of marbles but in the real version we
have eight marbles so now I need a way
to divide all the marbles onto eight so
if you remember week added a divided by
eight swing to be asked me the branch
from Gothenburg has sent me in the first
3d print of that one and Here I am
adjusting the weight not on the backside
to really make the swing tip exactly
when it has eight marbles on it I tapped
and made hole in the plastic and I used
this lock nut to lock both in to place
and this really worked well you can
adjust this with very high precision to
fall exactly when when I wanted to fall
but I realized that this swing is too
slow because the conveyor belt can lift
eight eight eight eight eight eight
eight marbles fast like that and the
swing can't handle that high marble
pressure so I needed another way to
divide by eight so I've been toting
another system I've been trying this
I've been trying duck when I come up
with is this to divide one single roll
onto eight just before the conveyor
about
this seems to be very reliable so if I
know these marvels the marbles come into
the ring gear from the planetary gearset
the blue line there and they come in
this new exit thing here that has quite
complicated geometry but I think this
will work great it attaches to the
mainframe here as you can see I added
some texts this 3d printed part here
just for fun
the marbles come in this thing they get
split up onto the four channels like I
talked about last week over the big
demagnetizing wheel the magnets are not
gonna be colored it's just for symbolism
the marbles done I'm not really done
with this is it sketches the marbles
done gets collected into one row by this
loft command I used to create this shape
here and then they go into this and this
is one of the most complicated things
that I've ever carried because the
geometries on these eight slopes are all
individual so they have 5 degrees slope
seen from this direction but they also
have a 5 degree slope seen from this
direction they're all individual from
the start and need to end up at the same
spot in the end so that was a little bit
complicated this works exactly like the
marble divider the channels that are
full we'll skip the marbles and the
models will roll into the empty channels
and then they will be lifted up by this
the conveyor belt system and the cool
thing is so I found this inspiration
from a YouTube video for like some kind
of industrial solutions for nuclear
plants and recycling stations where the
uses chain links and was actually seeing
that video that got me into understand
how I can build a marble conveyor belt
that is efficient and looks good
so each chute that holds the marbles has
a gear tooth shape so up here they turn
into a gear drive and the chain links is
also fitting in here
between the gear as you can see here and
the cool thing is that this conveyor
belt is not driven by these gears it's
not driven by a rotating mechanism this
conveyor belt is driven by the two
Pistons these two Pistons will move up
and down with 40 millimeters travel so
just just you can see here the right
piston here is connected to half of the
fish stair steps and the left piston is
connected to the other half and I also
implemented spring tension mechanism
here to help the Pistons fight gravity a
little bit and on this side we're going
to have ratchets they are not sketched
in this design yet but they are coming
out to the left side here and they will
go inside this conveyor belt here and
the ratchet will lift the tooth
themselves every chute will
what-what-what-what so there's there are
several things that is very very good
with this design we're losing very
little height if we look at it straight
from the side like this let me put on
orthographic and another perspective and
then we have a really flat view like
this so you can see that this is the top
of the marbles and down here where they
picked up is just five centimeters or
something and then we done a lot with
five centimeter fall height we
demagnetize the marbles and we routed
them around and back and if we look from
the front of the machine
[Music]
we are actually not going out that far
to the left with this design this
conveyor belt reminds me of this snake
rattle and roll game which I loved when
you climb the waterfall you know in the
like world seven super-difficult the
marbles are like climbing the snake
rattle and roll system so when these
marble shuttles reaches the top it will
tip over then the marbles will then roll
on the backside on the chute that was
before them if you see the structure
here is that the marbles will start to
roll on this surface so to speak it's
right under the marbles on this one so
they will roll on the swing that was
before them and roll off into some
tracks that I did not design yet so so
that's the idea right now I think this
is very viable because I've done a lot
of prototyping to get to this point so
when I built the first machine I only
made videos when I was done with parts
and I was regretting off towards that I
didn't show all mistakes and all the
change designs and stuff and the way I'm
making the videos now update every week
you really get to follow how I go into
the dance and how I try to dig myself
out of them thanks so much for watching
I'm editing these videos nowadays a
little bit with shoot-from-the-hip
attitude I hope you like it I hope
they're some kind of creation have a
great day everyone and see you on the
next main - got that Wednesday
