Looking back on Genuary 2025 I completed 23 of 31 prompts this year, which I'm pretty happy with. Moving away from the aim of doing one a day, or at least in the right order certainly helped. However, towards the end I definitely did run out of steam and ideas a bit, and found myself re-using concepts rather than coming up with anything novel. As a wrap up I wanted to regenerate and plot my favourites, to tidy up the code and prove I still could. As I've not always used consistent colours this came out as a 21-layer file, and of course I messed up the alignment on one of them! Making this grid was fun but I think I'll go back to plotting a single motif at a time. In order: 1, 2, 3, 5, 9, 10, 13, 14, 15, 16, 18, 22, 23, 24, 25, 29 -- which one was your favourite? I think there are a few I might want to develop further, though I did say that last year...

More grid-based layout than graphic design, but it was fun to use my previous gradient code and fit it into a randomly generated and selected grid layout. However, there are too many possibilities and I had to go through quite a few generation to get a sensible version that had all the features I wanted (a cell wide enough for the text, several cells that were approximately square to replace with polygons, gutters that weren't so thin that the cells almost overlapped)...

It also happens to be almost exactly one million millimeters (1km) long. The ink didn't actually run out but the pen got clogged up somewhere around the switch from vertical to horizontal lines.

KiCAD + Freerouting, I manually created a nonsense circuit schematic, placed the components in their positions more or less randomly, then let the auto routing do its thing to draw the copper traces. Been meaning to do this for a while and definitely some tweaks to be done. Such as randomly generating the components, connections, and positions and setting more sensible design rules for pen plotting. And not starting with a 5x5 mm central part where all the connections will get bulked up!

Code on the last slide, 42 lines added to my usual template page, that is - I'm still using libraries for convenient access to randomness, setting parameters, and drawing to SVG but this should need minimal changes to work directly on an HTML canvas object. About half of it implements "turtle" style drawing commands - move, save, turn, restore; the other half uses those to create random walks of sorts.

The mechanics of the rack and pinion worked surprisingly well on the second iteration, and should allow more granular control of the brush height and pressure and a wider range of motion. If I get round to actually adapting the software to it, that is. The first drawings here were made by manually editing the gcode to start the pen lift early and not wait for it to finish before painting the last segment of each drop so they line skills get thinner towards the top. I've first come across this idea in the paper "An Accessible, Three-Axis Plotter for Enhancing Calligraphy Learning through Generated Motion" (Fang et al, 2024). I designed the extra parts in SolveSpace to fit my existing pen lift setup and used an OpenSCAD gear generator by janssen86 for the rack and pinion shapes. #penplotter #3dprinting #gears #rackandpinion #experimental

"Heart" for the third day of the February #plotparty. Visualising the path of boid (bird-oid) agents, an algorithm for simulating flocking behaviour, getting all twisted within a heart shape. The "boids" consider their closest neighbours and move towards their center of gravity, try and move in the same direction, and avoid collisions with each other and the shape boundaries. This started out with an idea about using the boids to simulate butterfly positions for another metaphor but calculating their wing position and banking became a bit _too_ complicated.

So I built a not very realistic bird song generator so I could use the same parameters for the drawing. And then I messed up the path sorting so it's all drawn in reverse.

The two results are multiplied together, giving something like the XOR of the two shapes. I then use rejection sampling (more likely to select points far away from the shape, and never inside) and for each selected point calculate the gradient using the Sobel operator by comparing against nearby points. Black Rotring ink, 0.35mm line, on recycled white cartridge paper. About 75x75mm each and taking up to 10 minutes to draw. The video clip shows a few attempts at using different pens, but at this size the isograph worked best. The Bic pen I think needs longer lines before it draws properly and isn't suited to stippling, and the fountain pen lines were too thick and bled into each other too much, but might work at a larger size with more distance between the lines. #signeddistancefunction #sdf #penplotter #penplotterart #genuary #genuary29 #genuary2024

At the one hour mark, you're done" (genuary day 27) I wanted to make something that related to the process of coding and showing the passage of time. It didn't really work but was a fun challenge. I do believe it's possible to do live coding with a plotter but this attempt showed there's still some way to go to make the process more frictionless and interactive. The plotter started moving after 26 minutes, and around fifty minutes in I've got the first drawing that is based on the code written. So not much time left to get creative! And that was with being able to use a template that I put together for all my genuary pieces, and a server I had previously set up so I could send SVG code directly to the plotter from the web page. #livecoding #penplotter #penplotterart #genuary #genuary27 #genuary2024 #challenge

New pen and ink for me - the rotring refillable "isograph" fineliner - of course as it draws very accurate lines, showing up any slack in the plotter mounting.

While I wanted to stick to pen plotter drawings this year, this one called for an animation, so it was a nice excuse to get the automated lightpainting rig out again. I first generated fifty frames of the animation digitally, from a 3D scene of a camera moving through the star field of points. Then I mounted a red LED in place of the pen on my plotter, and connected the shutter release input on my camera to it as well so I can open and close the shutter (in bulb timer mode) with a gcode command at the beginning and end of every frame. Then it's just waiting for maybe half an hour while the robot rapidly moves the LED back and forth, and switching it on and off, creating traces in the long exposure photograph. Finally, those 50 photos are put together to create the two-second timelapse video.

Here I generated an island scene (yay, a better use for that dithering code), with the progress bar part drawn in a separate colour at first, and added back in after optimizing the rest of the image for plotting. Technically it shows how many optimized paths have been drawn so far, not overall progress, but it's probably still more accurate than most file copy estimates. Of course the ink ran out after about three hours... But I could measure the progress bar and restart at around the right layer.

Aligning the different pens is quite tricky and when I don't get it quite right, I end up with a 3D effect with the black lines being slightly offset from the silver. I first generate a voronoi pattern by randomly selecting points within the area and then relaxing the resulting mesh a little (LLoyd's algorithm). The shading is designed to follow a 2D Perlin noise field. The cells are sorted by desired hue and split into groups, where each group begins with a dip in the blue ink and draws maybe 10 or so cells, so the ink will gradually fade towards yellow. However, this process is not quite predictable as the ink in the dipping well mixes with that in the cartridge over time as well, so later groups tend to be more yellow than blue.

Sonic Pi is fun to play around with synths in...#plotparty day 2 - collaboration (between myself and my robots, in a way) A web app running on my phone sends SVG fragments to a program on my laptop which sends gcode to OctoPrint on a Raspberry Pi and that passes it on to the Arduino running Marlin and controlling the motors. Now I need a break! I think I'll go back to leaving the decision-making to the computers though. This was fun to build but the latency of a few seconds means I'm not truly reacting to what's been drawn already yet. #plotparty #splitscreen #penplotter #livedrawing #plotterart #ink

Second piece in this series: I'm now drawing the columns in sets of two and not fully in order, to cover more drawing distance for the same vertical movement, and to reduce the ink spilling into adjacent columns (this still happens a bit, was more obvious with the previous yellow and purple). Not sure if I like the two up columns yet, it reduces the entropy somewhat.
