In every stage of these Oppressions We have Petitioned for Redress in the most humble terms: Our repeated Petitions have been answered only by repeated injury. A Prince, whose character is thus marked by every act which may define a Tyrant, is unfit to be the ruler of a free people.

He has made Judges dependent on his Will alone, for the tenure of their offices, and the amount and payment of their salaries. He has erected a multitude of New Offices, and sent hither swarms of Officers to harrass our people, and eat out their substance.

Is anyone else noticing an uptick in seemingly fake accounts this week? I suddenly have 11 new "followers" but haven't posted anything attention worthy in months. Seems very suspicious.

Modified my cross-hatch shading algorithm to work with random pattern fills! On the left I'm using interactions between sin waves for shading, the right shows a traditional cross-hatching method. This model of The Veiled Woman by Corradini in the Louvre is from ScanTheWorld (mmf.io/o/6479)

I earned my MS studying origami mechanisms and now that I have a laser module attached to my plotter I can continue some of the work I was doing back then! Precision fabrication is still a major challenge, but this Kresling Tower structure made from PET and parachute nylon worked pretty well.

An origami-inspired folded tube (Kresling Pattern) constructed from laser-cut PET sheet sandwiched between layers of parachute nylon fabric. The image shows a mix of geometrically well-defined folded origami facets and organic crumpled fabric.

Got the itch to work on a laser cutter mode for my plotter using this cheapo 5.5W laser module. Here's the first cut! I tried to compensate laser power for feed rate, but looks like I went too far.

Trying some more weird stuff involving manipulating STL data before translating it to SVG (and plotter gcode). The background is also an STL model to test that I am tweaking things correctly on a per-model basis.

These curves use an L-system inspired method like Hilbert & Peano space-filling curves. From the perspective of the pen, the line can go straight, or turn CW/CCW - with instructions encoded in a text string like "-2 +2 F1 +3 -1..." etc. The resulting line is then offset and duplicated. #PenPlotter

A stack of plots on my drawing table with the beat up pen plotter tool-head visible on the left. On the table are four drawings of the same curve plotted using different pens. On the left is a trial plot using a Pigma MB brush pen in black. To its right is the same black brush pen with a Sakura GellyRoll 10 white gel pen overlaid on top. Above that are two plots made using Stabilo point 88s in different colorsA postcard sized plot of a red wiggly line over a soft teal background.

My neighborhood scooter kid was riding without handlebars, just holding onto the stick part! After confirming that it wasn't by choice and that he wanted a repair, I whipped up a replacement using a PVC pipe and some printed TPU grips. He assured me he, "doesn't do jumps" and he'd be careful!
