00:00:00.030 --> 00:00:04.650
welcome to another episode of intellect

00:00:01.890 --> 00:00:08.040
on Wednesdays and here it is business as

00:00:04.650 --> 00:00:10.219
usual as you can see I am trying out yet

00:00:08.040 --> 00:00:14.870
another lifting mechanism it's a

00:00:10.219 --> 00:00:14.870
comparable ratchet system combined

00:00:15.800 --> 00:00:24.439
that's basically the slow more rolling

00:00:34.120 --> 00:00:37.200
[Music]

00:00:40.100 --> 00:00:44.190
in the last week's video I built a

00:00:42.420 --> 00:00:47.039
ratchet marble lifting system and in

00:00:44.190 --> 00:00:50.070
that video I said this instead I came up

00:00:47.039 --> 00:00:52.110
with this a ratchet lifting system this

00:00:50.070 --> 00:00:55.860
system really had the ability to lift

00:00:52.110 --> 00:00:58.109
eight marbles per crank turn that was

00:00:55.860 --> 00:01:00.390
all wrong that ratchet system and the

00:00:58.109 --> 00:01:02.399
way it's driven only lifts for marbles

00:01:00.390 --> 00:01:03.870
per crank turn and in this episode I'm

00:01:02.399 --> 00:01:06.360
going to replace it with something

00:01:03.870 --> 00:01:08.030
better than a mouthful to explain why we

00:01:06.360 --> 00:01:12.790
need eight

00:01:08.030 --> 00:01:23.260
[Music]

00:01:12.790 --> 00:01:25.300
I thought I start with explaining why we

00:01:23.260 --> 00:01:27.790
need to lift eight marbles per crank

00:01:25.300 --> 00:01:32.400
turn you remember this test music I made

00:01:27.790 --> 00:01:32.400
to explain the magnet MIDI music system

00:01:33.030 --> 00:01:42.880
just to repeat every click here is one

00:01:38.560 --> 00:01:44.440
crank turn turn turn turn turn right so

00:01:42.880 --> 00:01:49.120
if we have a busy pattern on the

00:01:44.440 --> 00:01:52.570
vibraphone like this you can already see

00:01:49.120 --> 00:01:56.290
that we have one two three four notes

00:01:52.570 --> 00:02:01.840
that means that we need four marbles per

00:01:56.290 --> 00:02:03.550
crank turn to only to play this but the

00:02:01.840 --> 00:02:06.430
more machine X has more instruments in

00:02:03.550 --> 00:02:17.680
the vibraphone so if we add a simple

00:02:06.430 --> 00:02:20.620
snare of be like that we're up to nine

00:02:17.680 --> 00:02:23.180
marbles per to crank turns if so and if

00:02:20.620 --> 00:02:32.349
we then continue add a simple kick drum

00:02:23.180 --> 00:02:46.060
[Music]

00:02:32.349 --> 00:02:48.700
and then we add Hyatt on top of that you

00:02:46.060 --> 00:03:01.000
start to see here now seven marbles

00:02:48.700 --> 00:03:02.919
product seven six seven but this pattern

00:03:01.000 --> 00:03:21.819
is really simple if you make more

00:03:02.919 --> 00:03:24.189
complicated kick drum pattern you see

00:03:21.819 --> 00:03:26.459
we're already up to eight marbles per

00:03:24.189 --> 00:03:26.459
factor

00:03:33.480 --> 00:03:47.740
so this is drums and bar before girls

00:03:36.190 --> 00:03:50.950
have to face so with a very busy

00:03:47.740 --> 00:03:53.170
vibraphone pattern we exceed eight

00:03:50.950 --> 00:03:56.650
marbles per crank John here we have four

00:03:53.170 --> 00:03:59.950
seven and eleven marbles per crank turn

00:03:56.650 --> 00:04:02.080
so the marble machine would we'll be

00:03:59.950 --> 00:04:04.180
able to play this for some time because

00:04:02.080 --> 00:04:06.100
it has a lot of marbles stored upstairs

00:04:04.180 --> 00:04:08.980
but it won't be able to sustain it for

00:04:06.100 --> 00:04:10.720
five minutes when I make a really busy

00:04:08.980 --> 00:04:14.550
vibraphone pattern I need to keep the

00:04:10.720 --> 00:04:14.550
drum pattern a little bit less busy

00:04:16.000 --> 00:04:24.709
[Music]

00:04:27.470 --> 00:04:36.730
[Music]

00:04:38.920 --> 00:05:34.940
yes coffee what would we do without

00:04:45.110 --> 00:05:37.340
coffee so as you can see if we only had

00:05:34.940 --> 00:05:41.960
four marbles for a crank time we would

00:05:37.340 --> 00:05:50.900
only be able to play either only this or

00:05:41.960 --> 00:05:53.720
like only this or only this but if we

00:05:50.900 --> 00:05:55.640
can get eight marbles per crank turn we

00:05:53.720 --> 00:05:58.150
will be able to play almost something

00:05:55.640 --> 00:05:58.150
like this

00:06:00.909 --> 00:06:07.699
so that's why it's so important okay

00:06:04.719 --> 00:06:09.800
let's do some prototyping to solve this

00:06:07.699 --> 00:06:12.050
problem I started with some spring

00:06:09.800 --> 00:06:15.590
cleaning on my workshop and I built a

00:06:12.050 --> 00:06:17.750
weld card slash Robo wars contestant the

00:06:15.590 --> 00:06:19.610
draw for a sardar thought was a little

00:06:17.750 --> 00:06:22.090
bit tough his meeting this old tony's

00:06:19.610 --> 00:06:24.110
welding art in round one so we'll see

00:06:22.090 --> 00:06:27.289
what i have to measure with this

00:06:24.110 --> 00:06:28.849
prototype is the time for the marbles

00:06:27.289 --> 00:06:31.900
needs going there because this will move

00:06:28.849 --> 00:06:31.900
extremely fast

00:06:38.630 --> 00:06:43.990
[Music]

00:06:46.420 --> 00:06:49.639
[Music]

00:06:51.960 --> 00:07:01.430
[Music]

00:07:04.080 --> 00:07:10.440
[Music]

00:07:12.910 --> 00:07:18.670
so this is the improved prototype with

00:07:15.740 --> 00:07:21.350
some changes and see if we can get up to

00:07:18.670 --> 00:07:23.450
marble speed with that I have a slow-mo

00:07:21.350 --> 00:07:28.670
camera set up the only thing I need now

00:07:23.450 --> 00:07:36.910
is the marbles so let's go over here and

00:07:28.670 --> 00:07:41.330
look and of course the one box I need is

00:07:36.910 --> 00:07:44.630
guarded by a demon I love animal but

00:07:41.330 --> 00:07:46.900
these long leg things have to convince

00:07:44.630 --> 00:07:50.930
it that this is the wrong box to sit on

00:07:46.900 --> 00:07:57.520
hello my friend can I please take my

00:07:50.930 --> 00:07:57.520
marble whoa okay he went that good

00:08:04.160 --> 00:08:26.760
[Music]

00:08:24.219 --> 00:08:46.629
this one up

00:08:26.760 --> 00:08:46.629
[Music]

00:08:54.040 --> 00:09:04.430
17 divided on 25 0.68 four strokes

00:09:00.009 --> 00:09:06.709
divided on 0.68 seconds equals five

00:09:04.430 --> 00:09:13.130
point eight miles per second times 16

00:09:06.709 --> 00:09:18.170
this was 352 BPM actually that's a nice

00:09:13.130 --> 00:09:20.449
Headroom yay this proves that the

00:09:18.170 --> 00:09:22.610
marbles loads fast enough in this method

00:09:20.449 --> 00:09:25.189
for playing music up to 200 bpm

00:09:22.610 --> 00:09:27.829
and in the prototype I'm using one row

00:09:25.189 --> 00:09:30.769
of marbles but in the real version we

00:09:27.829 --> 00:09:34.430
have eight marbles so now I need a way

00:09:30.769 --> 00:09:36.620
to divide all the marbles onto eight so

00:09:34.430 --> 00:09:39.230
if you remember week added a divided by

00:09:36.620 --> 00:09:41.029
eight swing to be asked me the branch

00:09:39.230 --> 00:09:44.290
from Gothenburg has sent me in the first

00:09:41.029 --> 00:09:47.420
3d print of that one and Here I am

00:09:44.290 --> 00:09:51.199
adjusting the weight not on the backside

00:09:47.420 --> 00:09:54.350
to really make the swing tip exactly

00:09:51.199 --> 00:09:56.600
when it has eight marbles on it I tapped

00:09:54.350 --> 00:09:59.810
and made hole in the plastic and I used

00:09:56.600 --> 00:10:02.420
this lock nut to lock both in to place

00:09:59.810 --> 00:10:04.970
and this really worked well you can

00:10:02.420 --> 00:10:07.730
adjust this with very high precision to

00:10:04.970 --> 00:10:09.860
fall exactly when when I wanted to fall

00:10:07.730 --> 00:10:12.769
but I realized that this swing is too

00:10:09.860 --> 00:10:14.839
slow because the conveyor belt can lift

00:10:12.769 --> 00:10:17.480
eight eight eight eight eight eight

00:10:14.839 --> 00:10:20.959
eight marbles fast like that and the

00:10:17.480 --> 00:10:23.600
swing can't handle that high marble

00:10:20.959 --> 00:10:26.990
pressure so I needed another way to

00:10:23.600 --> 00:10:28.699
divide by eight so I've been toting

00:10:26.990 --> 00:10:31.160
another system I've been trying this

00:10:28.699 --> 00:10:35.990
I've been trying duck when I come up

00:10:31.160 --> 00:10:38.149
with is this to divide one single roll

00:10:35.990 --> 00:10:40.220
onto eight just before the conveyor

00:10:38.149 --> 00:10:47.850
about

00:10:40.220 --> 00:10:54.120
this seems to be very reliable so if I

00:10:47.850 --> 00:10:56.010
know these marvels the marbles come into

00:10:54.120 --> 00:10:58.710
the ring gear from the planetary gearset

00:10:56.010 --> 00:11:02.580
the blue line there and they come in

00:10:58.710 --> 00:11:05.970
this new exit thing here that has quite

00:11:02.580 --> 00:11:08.910
complicated geometry but I think this

00:11:05.970 --> 00:11:12.450
will work great it attaches to the

00:11:08.910 --> 00:11:15.710
mainframe here as you can see I added

00:11:12.450 --> 00:11:18.240
some texts this 3d printed part here

00:11:15.710 --> 00:11:24.450
just for fun

00:11:18.240 --> 00:11:27.060
the marbles come in this thing they get

00:11:24.450 --> 00:11:30.150
split up onto the four channels like I

00:11:27.060 --> 00:11:32.370
talked about last week over the big

00:11:30.150 --> 00:11:35.630
demagnetizing wheel the magnets are not

00:11:32.370 --> 00:11:38.130
gonna be colored it's just for symbolism

00:11:35.630 --> 00:11:40.290
the marbles done I'm not really done

00:11:38.130 --> 00:11:43.110
with this is it sketches the marbles

00:11:40.290 --> 00:11:46.710
done gets collected into one row by this

00:11:43.110 --> 00:11:49.860
loft command I used to create this shape

00:11:46.710 --> 00:11:52.050
here and then they go into this and this

00:11:49.860 --> 00:11:53.520
is one of the most complicated things

00:11:52.050 --> 00:11:56.640
that I've ever carried because the

00:11:53.520 --> 00:12:01.890
geometries on these eight slopes are all

00:11:56.640 --> 00:12:04.860
individual so they have 5 degrees slope

00:12:01.890 --> 00:12:07.230
seen from this direction but they also

00:12:04.860 --> 00:12:09.780
have a 5 degree slope seen from this

00:12:07.230 --> 00:12:11.790
direction they're all individual from

00:12:09.780 --> 00:12:14.510
the start and need to end up at the same

00:12:11.790 --> 00:12:18.300
spot in the end so that was a little bit

00:12:14.510 --> 00:12:20.010
complicated this works exactly like the

00:12:18.300 --> 00:12:22.800
marble divider the channels that are

00:12:20.010 --> 00:12:25.530
full we'll skip the marbles and the

00:12:22.800 --> 00:12:29.760
models will roll into the empty channels

00:12:25.530 --> 00:12:33.480
and then they will be lifted up by this

00:12:29.760 --> 00:12:37.830
the conveyor belt system and the cool

00:12:33.480 --> 00:12:41.370
thing is so I found this inspiration

00:12:37.830 --> 00:12:44.070
from a YouTube video for like some kind

00:12:41.370 --> 00:12:47.160
of industrial solutions for nuclear

00:12:44.070 --> 00:12:50.970
plants and recycling stations where the

00:12:47.160 --> 00:12:53.860
uses chain links and was actually seeing

00:12:50.970 --> 00:12:56.019
that video that got me into understand

00:12:53.860 --> 00:12:58.600
how I can build a marble conveyor belt

00:12:56.019 --> 00:13:04.510
that is efficient and looks good

00:12:58.600 --> 00:13:09.190
so each chute that holds the marbles has

00:13:04.510 --> 00:13:12.310
a gear tooth shape so up here they turn

00:13:09.190 --> 00:13:13.720
into a gear drive and the chain links is

00:13:12.310 --> 00:13:18.610
also fitting in here

00:13:13.720 --> 00:13:20.769
between the gear as you can see here and

00:13:18.610 --> 00:13:23.589
the cool thing is that this conveyor

00:13:20.769 --> 00:13:26.560
belt is not driven by these gears it's

00:13:23.589 --> 00:13:29.890
not driven by a rotating mechanism this

00:13:26.560 --> 00:13:32.200
conveyor belt is driven by the two

00:13:29.890 --> 00:13:36.850
Pistons these two Pistons will move up

00:13:32.200 --> 00:13:38.380
and down with 40 millimeters travel so

00:13:36.850 --> 00:13:41.350
just just you can see here the right

00:13:38.380 --> 00:13:44.620
piston here is connected to half of the

00:13:41.350 --> 00:13:47.769
fish stair steps and the left piston is

00:13:44.620 --> 00:13:51.670
connected to the other half and I also

00:13:47.769 --> 00:13:55.269
implemented spring tension mechanism

00:13:51.670 --> 00:13:59.079
here to help the Pistons fight gravity a

00:13:55.269 --> 00:14:00.820
little bit and on this side we're going

00:13:59.079 --> 00:14:03.399
to have ratchets they are not sketched

00:14:00.820 --> 00:14:05.890
in this design yet but they are coming

00:14:03.399 --> 00:14:08.560
out to the left side here and they will

00:14:05.890 --> 00:14:10.990
go inside this conveyor belt here and

00:14:08.560 --> 00:14:13.829
the ratchet will lift the tooth

00:14:10.990 --> 00:14:16.810
themselves every chute will

00:14:13.829 --> 00:14:18.640
what-what-what-what so there's there are

00:14:16.810 --> 00:14:21.459
several things that is very very good

00:14:18.640 --> 00:14:23.199
with this design we're losing very

00:14:21.459 --> 00:14:25.709
little height if we look at it straight

00:14:23.199 --> 00:14:27.970
from the side like this let me put on

00:14:25.709 --> 00:14:29.769
orthographic and another perspective and

00:14:27.970 --> 00:14:34.149
then we have a really flat view like

00:14:29.769 --> 00:14:36.370
this so you can see that this is the top

00:14:34.149 --> 00:14:38.470
of the marbles and down here where they

00:14:36.370 --> 00:14:40.449
picked up is just five centimeters or

00:14:38.470 --> 00:14:42.390
something and then we done a lot with

00:14:40.449 --> 00:14:45.190
five centimeter fall height we

00:14:42.390 --> 00:14:47.529
demagnetize the marbles and we routed

00:14:45.190 --> 00:14:49.390
them around and back and if we look from

00:14:47.529 --> 00:14:50.779
the front of the machine

00:14:49.390 --> 00:14:54.930
[Music]

00:14:50.779 --> 00:14:57.720
we are actually not going out that far

00:14:54.930 --> 00:15:00.690
to the left with this design this

00:14:57.720 --> 00:15:02.880
conveyor belt reminds me of this snake

00:15:00.690 --> 00:15:05.339
rattle and roll game which I loved when

00:15:02.880 --> 00:15:08.310
you climb the waterfall you know in the

00:15:05.339 --> 00:15:10.260
like world seven super-difficult the

00:15:08.310 --> 00:15:13.769
marbles are like climbing the snake

00:15:10.260 --> 00:15:16.230
rattle and roll system so when these

00:15:13.769 --> 00:15:19.529
marble shuttles reaches the top it will

00:15:16.230 --> 00:15:21.810
tip over then the marbles will then roll

00:15:19.529 --> 00:15:24.930
on the backside on the chute that was

00:15:21.810 --> 00:15:27.810
before them if you see the structure

00:15:24.930 --> 00:15:30.810
here is that the marbles will start to

00:15:27.810 --> 00:15:33.750
roll on this surface so to speak it's

00:15:30.810 --> 00:15:35.670
right under the marbles on this one so

00:15:33.750 --> 00:15:38.910
they will roll on the swing that was

00:15:35.670 --> 00:15:43.079
before them and roll off into some

00:15:38.910 --> 00:15:47.100
tracks that I did not design yet so so

00:15:43.079 --> 00:15:48.839
that's the idea right now I think this

00:15:47.100 --> 00:15:52.560
is very viable because I've done a lot

00:15:48.839 --> 00:15:54.899
of prototyping to get to this point so

00:15:52.560 --> 00:15:56.940
when I built the first machine I only

00:15:54.899 --> 00:15:58.770
made videos when I was done with parts

00:15:56.940 --> 00:16:00.870
and I was regretting off towards that I

00:15:58.770 --> 00:16:04.290
didn't show all mistakes and all the

00:16:00.870 --> 00:16:06.390
change designs and stuff and the way I'm

00:16:04.290 --> 00:16:09.000
making the videos now update every week

00:16:06.390 --> 00:16:12.000
you really get to follow how I go into

00:16:09.000 --> 00:16:14.550
the dance and how I try to dig myself

00:16:12.000 --> 00:16:16.860
out of them thanks so much for watching

00:16:14.550 --> 00:16:18.260
I'm editing these videos nowadays a

00:16:16.860 --> 00:16:21.930
little bit with shoot-from-the-hip

00:16:18.260 --> 00:16:24.209
attitude I hope you like it I hope

00:16:21.930 --> 00:16:25.770
they're some kind of creation have a

00:16:24.209 --> 00:16:27.250
great day everyone and see you on the

00:16:25.770 --> 00:16:31.659
next main - got that Wednesday

00:16:27.250 --> 00:16:31.659
