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.

This is so satisfying

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.

the drawings this thing makes are absolutely beautiful. awesome machine!

Dude this is better art than the shit I see at art museum these days...

The machine sounded like a bowling going down the lane. This is a cool machine that makes these awesome squigly rainbows.

These are fascinating, almost hypnotic to watch. Do you have photographs of the finished drawings anywhere? Do the patterns ever repeat?

dude you could sell those drawings for tons of money to a modern art museum

I think that drawing is a stylized version of the universe.

This is a little more entertaining than the other drawing machine I just watched. Not by much but it's better

This isn't computer programming, this is engineering and mathematics. Mind you, computers make this much easier to design.

Very Interesting. Do you use a software do you use to write the programms to these drawings or is it only mechanical?

I can just smell the ball point pen ink now, reminding me of spiralgraph when I was 8.

I could watch that for hours. Really cool.

I enjoyed watching this. My kids think it is neat! Thank you Alfred Hoehn!

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.

U SHOULD MAKE A FAST MOTION VIDEO AND IT WILL BE REALLY COOL

dudddee the drawing is sick man

that moment when the pen runs out of ink...

Damn! I could watch this for days, and yet i would´nt think I wasted time.

Wow that's a nice pen.

Quite simple machine, with the most awesome result! Not often you see something cool as that :b

this is pretty awesome

I don't know why but this whole video has a strong '80s vibe to it

Danke, diese Idee würde wahrscheinlich die Vermarktung meiner Maschinen vorantreiben. Alfred Hoehn

THAT PEN IS AMAZING!!!

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.

if you start the wheels at different phases, does it make a completely different drawing?

damn those are some beautiful lines!

This is so cool. It is computer controlled or just random drawing. Like, can you know what the machine will draw?

THATS SO NICE

That's really quite relaxing to watch. Nice work. :)

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

Way cool

Time to rage when the pen runs out of ink

Soooo ein schönes Bild! Tolle Leistung!

i could watch this for days

So simple, yet so amazing! Love it!

Now that it what I call art!!!

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? -.

damn that pen had a loot of ink

Awesome

superb amendment, astounding

SO COOL !!!!

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.

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?

Cooles Mandala..Viel Spaß beim ausmalen ! :)

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..

So this is how the Windows screensavers got created.

Wow, that's what I call art! How many turns does it have to do before it repeats itself?

Seems like a nice machine.

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!

I had one of these as a kid... it was called a Spirograph.

wow thats friggen awsome

Sehr entspannend zu sehen!:)

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.

These are the shapes you see when on DMT. In some strange way this all seems logical and fitting

i wouldn't mind getting some of those drawings and framing them

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?

That's so cool!

its a drawing that can't be stopped or else it would be incomplete

Hi ! Very beautiful, it seems the machine is blocked at 3:42.

very nice...

How many times did you have to stop it to lick the tip of the ink-pen?

Now stuff like thsi is useful. Show us the hidden geometry!

@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

Woah! As far as I'm concerned, it's a 3 dimensional me gusta in 2 dimensional troll.

This is me studying math for tomorrow exam. Mc Donald`s here I come!

man,thats great!!!!!!

kan you make a full video of the entire process in a timelapse? perhaps a bit sped up

Really really beautiful!!! Thanks.

machines can replace artists!!

It would be great to use a color changing pen

Awesome!! I just wonder how this machine change the pitch between lines..

I rewound and looked at the machines more closely, so I digress.

so happy I don't do math anymore, otherwise I'd jizzed mah pants

3:42 Incorrect but that's awesome :)

Did you use foam board or wood for the arms?

thats the best way to waste a ballpen

Thank You for compliments Alfred Hoehn

Yes, this is really mathematics. Thank You Alfred Hoehn

Interesting video! It seems like the drawing should be symmetrical. Why are they not?

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!

This pen works great.

I can smell the ink!

Do you think that it can be made on a computer, in 3D or 4D maybe?

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.

@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

nice pen :D

@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

Maios return to the begin in about 2 hours. best Alfred Hoehn

This maching is absolutely incredible. Directions for building one?

I am attempting to write a software simulation of this machine. The speed of the left spirograph is 8 sec / revolution, and the speed of the right spirograph is a slower 10 seconds per revolution, in the opposite direction. But the speed of both smaller wheels is 6 sec per rev, so each small wheel is not rolling inside the large wheel like a normal spirograph, but instead must be geared underneath with slightly different size gears. I get a similar design, but it almost repeats every cycle, and exactly repeats every 4 cycles. I will try making the speeds different by a small amount so they have no common factor. Since there is no rolling now, the ratio of wheel sizes does not matter.

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.

i'm really fascinated at this!

@TheBeatDropper96 It is only a analog machine, no computer programming. Thank you Alfred

cool Spirograph on steroids

Program it to do something beautiful , like a tall ship under full sail !
