The setup at 3:50 did the most beautiful drawing I've ever seen on these machines... Very good job!

The magnets are 4mm spheres. The device has been in our loft for 6 years, but I got it down and reconstructed it and it still works perfectly!

I'll make a harmonogram for you when I get home

Absolutely incredible. This is the most precisely balanced harmonograph I can find on youtube!

Thanks! I am very picky about accuracy when constructing projects.

Love it! I've been thinking about doing some drawing recently. I built a motorised harmonograph which wasn't anywhere near accurate as this so I may well attempt a proper one some day.

Does anyone know where to acquire the magnetic connectors? Fabulous Idea!

Ray McCon sorry for the delay in replying. I just saw your comment. I got mine at first4magnets.com I think

That was fast, thank you. I'll give the balsa wood a try. Right now my arms are 3/8 x 3/8 birch ply wood which might be to heavy. Also, are you unsing magnets for the arm connections?
@GavinGreenawayMusic6 жыл бұрын
jrae2424 Yep - almost certainly your arms are the main problem. Ideal weight = approx. zero!! Try the balsa wood. I used a spherical magnet for the links - they sit nicely in the head of a Phillips screw and are low friction.

can u please tell the size of the magnets??

Very nice, inspired me ro build one myself. But its not rotating for very long, and the 2 arms on the single axis seem to stop first. Any ideas or suggestions. Thanks

jrae2424 Look for any sources of friction. We used sharp pointed screws on metal for the fulcrums (if that’s the correct word). Reduce the weight at the pen so it’s not too heavy - make your arms as light as possible. We used balsa wood. They don’t need to be strong.

How you make Three colors plots ???!!!
@gvngrnwy8 жыл бұрын
Two possibilities: just do 3 plots and change the pen each time (as shown) or put 3 pens together for a different, more random effect

How large did you make the holes for the pendulums?
@gvngrnwy8 жыл бұрын
Using electric drill with an attachment I don't know the name of. It has a central pilot drill then an arm at 90 degrees with sharp angle point. Adjust length of arm for size of hole.
