The last one seems like a washing machine drum.

These are generated as angle paths: at each step a unit length line is drawn and then the orientation is changed by an angle depending on the step number. The function to chose orientation change is c × (a×n² + b) / n radians, where c is of the form 2PI/k, k integer, a and b are also integers. Around 100K steps.

A few months back I posted here about a tool I built (svgfontmaker.com) that turns a scan of your handwriting into an SVG font (original post). The feedback in that thread is what kept me working on it, I wanted something like this for myself, and figured the community might find it useful too

Biggest change since then (aside from fixing bugs around saving :) ): you can now create multiple variations of a single letter. Draw three different 'a's and the tool randomly picks between them as it lays out your text. This was the thing that bugged me most about plotting with a handwriting font, as soon I used the same word a few times times in a letter, it became apparent a machine wrote it. With variants on, it actually reads like a person wrote it.

Getting there took a detour. The SVG font format has no concept of randomized glyph alternates, so I added a document layer — your text now lives in a project where the variation logic runs at render time instead of being baked into a static font file.

I also worked on the stability of the app overall - a few people correctly called out that their work was getting dropped midway through making a font.

It is still pretty painful having to manually trace letters, and I don't quite have the automated processing at a point yet where it just creates a font automatically.

Would love feedback on:

• If you've used handwriting fonts for plotting, how are you currently tracing/cleaning your letters?
• What else would make this useful for you?

For years now, I am working iteratively on my wall plotter project called Dot-Bot. During the first full scale tests, we ran into issues with the forces being too high on the side motors when the gondola moves in the upper middle portion of the canvas. This led to wavy lines since the GT2 belts started to oscillate like guitar stings under high loads. With this third center station, we are able to decrease the force on the side motors dramatically improving quality noticeably where it matters the most, in the center of the wall.

I’m building corexy vertical pen plotter and just finished pen changing macros. A little modification to parts are needed but this is just formality. Next step is to build gcode generator. More updates soon

Last Saturday I brought my artwork and my plotter to an arts and crafts market.
Of course, the plotter took center stage! I made lots of postcard-sized drawings live for wide eyed kids, in exchange for small donations to charity. Demanding,but totally worth it!
These are some digital previews. All drawings come from python code.

"Bees & Flowers" is a set of truchet tiles drawn by me in Inkscape!

My new project has procedural tree gen with occlusion and path optimization. This is the first plot after working on it for nearly a week already. I have a lot more ideas for improvements and things to try to make the scene more interesting.

I will be focusing on this project for the next couple weeks and plotting a few more every day. My goal is to have 3 really nice pieces to submit to a big local call to artists that I really want to get accepted into.

B5-sized plot.

Hi everyone,
it is weekend so I thought to share some artwork again.
This artwork is called Voronoi Spiral was created/programmed by Reinder using Turtletoy tool

From Wikipedia:
In mathematics, a Voronoi diagram is a partition of a plane into regions close to each of a given set of objects. It can be classified also as a tessellation. In the simplest case, these objects are just finitely many points in the plane (called seeds, sites, or generators). For each seed there is a corresponding region, called a Voronoi cell comprising all points of the plane closer to that seed than to any other. The Voronoi diagram of a set of points is dual to that set's Delaunay triangulation.

For a recent video I'd been playing with drawing lots of straight lines, with random spacing between them. Tinkered a little bit with vary the chances of which colour each line would be, and changing that chance further along the 'ribbon' to blend from one colour to the next.

Nine coloured pens in nine passes. Various A5 and A6 results.

Was excited to scale up some of the small spray paint and ink pieces I made last month. I spent hours plotting this one to just rush it at the end and tear my paper taking off the paint mask. I bought this Nichiban low-tack paper tape and it's amazing but you still need to peel it slowly and at a shallow angle. Lesson learned.

Just some of my first experiments using rust to plot directly to axidraw. If you are interested in the code side, check my post in r/plottercode
