It's amazing how simple non linear systems can produce such beautiful images. Probably it's no coincidence that these drawings look so much like those "flames" fractals.
Laynie Fingers If the 'rules', or the speed of the motor and other factors like the diameters of the circles and linking are not changed during the operation, ideally it would repeat. But the pen is not copletely accurate and the links can move so it may not repeat itself.
I like that the machine hiccups in places, creating these breaks in the perfect rhythm of the lines. The ink flow stuttering is also nice, keeps it from becoming too mechanical.
I'm doing parametric modelling for my architecture now and these forms are amazing! Out of curiosity, after a long time, will it repeat the same thing again? or is it forever drawing a new line?
Ich habe auch so ein ähnliches Gerät gebaut und würde mich interessieren, ob die kleineren Drehscheiben ein eingebautes Getriebe haben. Sind da Zahnräder drinnen verbaut?
I am using this as inspiration for a project I am working on now. I am at the stage of choosing the motors. Obviously our projects will have different torque requirements because of differing weights. (your spinning plate is metal and mine is light wood). How do I approximate the torque required to spin my disks and push my pantograph and pen along the paper, so as to choose the proper motor? Do I just use the weight of everything and the approximated friction of pen on paper? Thank you, your drawing machine is really incredible.
Excellent!! Superb!! It is very interesting how easily and how fast you can touch high complexity just by combining simple motions. How long doesn it take to repeat itself? When are these movenments periodic? -.
Will the machine's drawing eventually form a closed loop? To find how long before the loop closes, you would need to find the smallest number that all the periods of all the wheels divide into (I think). So if the large wheels' periods are 9 and 10 seconds, and the 2 small wheels' periods are 6 and 7 seconds, then what is smallest number that is multiple of all those numbers? How about 630? So after 630 seconds or 10½ minutes, the loop would close. Course, that's assuming periods are exact.
Quick question, is there a motor or gear driving the small circle as well? Or, is the small wheel just fixed to the large wheel and its turning freely as the large wheels are being driven around?. Also, is there a ratio between how large small circles are compared to small circles? Amazing video!
@alfredhoehn if you thought this was directed at you, it wasn't, it was directed towards whoever could possibly dislike this, i thought it was amazeing
The guilloch is soo awesome, this machine knows how to make universal geometry! Try the hub with different shapes, square triangle rectangle and see what happens..
With a lot of these type machines you get a kind of osculation, or geometric pattern and it's really uniform, but not very interesting. But this seems much more random. That's very intriguing to me.
Ha Rosamvietnam The Motor is a DC 12V Motor, made in switzerland and very expensiv. Each Whell has a Motor. The speed of the Motors does not change, but it's a few different. Thank You and best. Alfred Hoehn
@Sergiocrivelin The form is a mathematic parametric curve, derived from the mechanism geometry. You can adjust the results setting some parameters like the ratio of the gear train that control the rulers
Hallo Herr Höhn, bestaune immer wieder ihre technische Professionalität. Ich möchte gerne die gleiche Maschine nachbauen und möchte sie fragen ob sie auch ihre Unterlagen zur Verfügung stellen können? Würde mich freuen wenn es klappt. Viele Grüße
Yes, but you will have to implement virtual 'reels' of prime number size and speed, I will give it a go, It's outside what I normally do - so don't expect much.
+Alfred Hoehn Thanks for the response, I was referring to the lateral motion of the pen getting wider, not the actual pen point. Instead of the pen going over the same line repeatedly, the motion is offset on each cycle. I might be over thinking it too much, I just can't understand why the pen doesn't just go along the same line over and over. Now that I've watched it over a few times I'm guessing it has something to do with the offset of the two disks.
Ah... An electro-mechanical Spirograph kit... I loved these kind of drawings when I was a kid.
It's amazing how simple non linear systems can produce such beautiful images. Probably it's no coincidence that these drawings look so much like those "flames" fractals.
These are fascinating, almost hypnotic to watch. Do you have photographs of the finished drawings anywhere? Do the patterns ever repeat?
Laynie Fingers If the 'rules', or the speed of the motor and other factors like the diameters of the circles and linking are not changed during the operation, ideally it would repeat. But the pen is not copletely accurate and the links can move so it may not repeat itself.
The machine sounded like a bowling going down the lane. This is a cool machine that makes these awesome squigly rainbows.
the drawings this thing makes are absolutely beautiful. awesome machine!
I like that the machine hiccups in places, creating these breaks in the perfect rhythm of the lines. The ink flow stuttering is also nice, keeps it from becoming too mechanical.
This is a little more entertaining than the other drawing machine I just watched. Not by much but it's better
This is so satisfying
+huki07 Thank You, Alfred
if you start the wheels at different phases, does it make a completely different drawing?
Very Interesting. Do you use a software do you use to write the programms to these drawings or is it only mechanical?
Dude this is better art than the shit I see at art museum these days...
the designs are so amazingly lovely to look at.... but I'm, more, wondering about the pen! What kind was that - never seen one so smooth before.
kan you make a full video of the entire process in a timelapse? perhaps a bit sped up

I could watch that for hours. Really cool.
This is so cool. It is computer controlled or just random drawing. Like, can you know what the machine will draw?
how are those small discs rotating on larger discs ?
I enjoyed watching this. My kids think it is neat!
Thank you Alfred Hoehn!
Awesome!! I just wonder how this machine change the pitch between lines..
Wow, that's what I call art! How many turns does it have to do before it repeats itself?
I can just smell the ball point pen ink now, reminding me of spiralgraph when I was 8.
Quite simple machine, with the most awesome result! Not often you see something cool as that :b
I don't know why but this whole video has a strong '80s vibe to it
Indeed
Well I imagine the machine is controlled by HAL.
would it be whole black if you just leave it there?
Interesting video! It seems like the drawing should be symmetrical. Why are they not?
Do you think that it can be made on a computer, in 3D or 4D maybe?
Damn! I could watch this for days, and yet i would´nt think I wasted time.

This maching is absolutely incredible. Directions for building one?
what would happen if u changed the speed of just one of the motors? will it still make cool drawings or will they turn to crap?
Excellent!! Superb!!

This isn't computer programming, this is engineering and mathematics. Mind you, computers make this much easier to design.
@TheBeatDropper96
It is only a analog machine, no computer programming.
Thank you
Alfred
how long does the ink last if you just let it draw day and night?
THAT PEN IS AMAZING!!!
LOOK AT MY PEN, MY PEN IS AMAZING!!!
Thank You for compliments
Alfred Hoehn
I think that drawing is a stylized version of the universe.
i wouldn't mind getting some of those drawings and framing them
How many times did you have to stop it to lick the tip of the ink-pen?
if you get good pens they won't dry out
also, klicking it does nothing
*licking

damn those are some beautiful lines!
Hi ! Very beautiful, it seems the machine is blocked at 3:42.
These are the shapes you see when on DMT. In some strange way this all seems logical and fitting
@alfredhoehn does it happen because the discs have slightly different angular velocities?
@Maxr616
Theoretical yes, it would be whole black. But in reality it begins to draw on the same lines after 3-4hours.
Thank you
Alfred
dude you could sell those drawings for tons of money to a modern art museum
What type of pens did you use?
cool what do the finished pictures look like
So simple, yet so amazing! Love it!
Hello
I was wondering what are the measurements of the sticks, and what are the clamps you use to hold them?
That's really quite relaxing to watch. Nice work. :)
@alfredhoehn if you thought this was directed at you, it wasn't, it was directed towards whoever could possibly dislike this, i thought it was amazeing
Did you use foam board or wood for the arms?
+Dan Man
I'm using foam board for the arms Alfred
Danke, diese Idee würde wahrscheinlich die Vermarktung meiner Maschinen vorantreiben.
Alfred Hoehn
looks like one of the screen saver on window 95, where's the start console and internet at the bottom left?
@alfredhoehn there's a screensaver that draws similar figures, but in a 3-Dimensional fashion instead
so satisfying, wonderful
@Tambitiousone
Thank you for compliments
Alfred
Soooo ein schönes Bild! Tolle Leistung!
Are the discs exactly the same?
what are the proportions of the hands?

One simple question. How those motors turns than slowly?
By the way Great idea
how long be fore it starts to trace over the original lines
sure, but.. will it blend?
@NuustikCat
Thank You Alfred Hoehn
U SHOULD MAKE A FAST MOTION VIDEO AND IT WILL BE REALLY COOL
Thank You for compliments!!!
Alfred
Seems like a nice machine.
@felineboy
Thank You for compliments Alfred Hoehn
@TheKBbeat
Hallo, Danke für das Kompliment. Die Zeichnungen gibts auch farbig. Wo bist Du hause?
Alfred Hoehn
dudddee the drawing is sick man
I always wanted this! I could now print homework with led and pretend i did it... HAHA can't wait for this to be for sale.
no prob, I guess the shape of the hubs really don't matter since they rotate anyway

kann mich garnicht sattsehen ... das ist so toll und die Bilder, die entstehen sind wunderschön!
Hallo Adrian. Es freut mich, dass Dir meine Maschinen so gefallen. Wenn Du mal in Basel bist, komm sie anschauen. Gruss Alfred Hoehn
das nehm ich mir fest vor für das nächste Mal wenn ich meine Tochter in St.Gallen besuche. beste Grüße!
Now that it what I call art!!!
Wow that's a nice pen.
do you think you could design a machine that symmetrically draws?
+PsykedAlex one on top of the other?
+Douglas Yellow yes sir
Does it only draw curves?
@Sergiocrivelin The form is a mathematic parametric curve, derived from the mechanism geometry. You can adjust the results setting some parameters like the ratio of the gear train that control the rulers
I had one of these as a kid... it was called a Spirograph.
Have you tried with different phase difference?
this is pretty awesome
Does it ever return to the first path?

damn that pen had a loot of ink
Theank You for Your nice comment.
Alfred Hoehn
I like your machine I want to create mine but with a different design. would you help me to do It ?
Could be a way to make crop circles. Just a thought...
What is causing the strokes of the pen to get progressively wider?
+Ryan Sereno , If You use a felt marker, then it get wider, Alkfred
+Alfred Hoehn
