-
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]
-
[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]
-
[Music]
-
[Music]
-
[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
