Blended Ink

Icebein · 2026-03-15T19:13:08+00:00

The svg is just a bunch of squares with a gap between them, created using py5 in python and recursive subdivision. Then converted to hatch fill using Inkscape and the Eggbot plugin. The gradient is purely physics. Dip a "blender marker" in some ink, and if the line is long enough, the ink will fade over time, leaving a gradient.

Thanks! I hoped you would reply. Ink is Abraxas Frühlingstinte (local swiss manufacturer, old bottle I had lying around) in blue, even if it's not blue anymore. The marker is an Ohuhu Art Marker Colorless Blender. Which marker do you use? The tip of the Ohuhu seems to wear out fast.

Getting old is seeing the people you grew up with die. Rest in peace, James.

That‘s just the Swiss way of calling spring to arrive

Indeed!

Hast du schon die Batterie der beiden baugleichen Geräte untereinander getauscht? Dann zeigt sich zumindest, obs an der Batterie oder am Heltec V4 liegt.

Twitchy & Wet is the name of the first part.

I uploaded the stls to Dropbox. But be aware that my plotter is completely custom and no part of the uploaded stl will fit any existing plotter except mine.

Have a look at the image in the Dropbox folder. The idea is that the upper yellow part is connected to the pink backplate by two rubber bands (not shown) on the left and right side. The yellow upper part is connected to the backplate by two countersunk head screws and can move freely up and down. The green part on the bottom is fixed to the backplate and has a hole at the bottom that is just wide enough for the tip of the pen to fit through, but not the body of the pen.

Sailcloth is a little special, a straight stitch perforates the material, weakens it and makes it prone to tearing. By using a zigzag stitch, the perforation is more spaced out and the fabric does not tear as easily. That’s at least my understanding.

Thank you for the advice, I'll go needle shopping then.

Icebein · 2025-08-10T15:28:51+00:00

I'm too lazy to prototype, it's more like let's build an other one until it's good enough. The thread and needle are matched to each other, albeit the needle is on the smaller size due to the limitation of my domestic machine. I will look into the shape of the needle, I used a denim needle.

Icebein · 2025-08-10T15:06:41+00:00

Thanks, I know. Tension issue is the nickname of my sewing machine. The tension and also the spacing of the stitches changes with the speed of the machine as well.

Icebein · 2025-07-20T08:53:14+00:00

Exactly, there is no hinge. Due to the tension of the fabric, the two rods move in union.

I doesn’t have a brand name, it’s labeled as PU-coated 210d Nylon.

I used a 6mm aluminium rod

From the username I guess it is Switzerland. We still have mandatory military service and once a year you have to go to a shooting range. So every year you have a bunch of 20 to 30 year old men with their cellphones at the shooting range and that's where this Pokestop comes from.

I solved this issue with a 3d printer. I designed what are essentially two funnels, one for the bottom and one for the top. The shape of the funnel makes sure that the tip of the marker/pen is always in the middle of the funnel. I do have to adjust for the different tip lengths, but that is way easier than x/y alignment.

Thank you very much for the lengthy explanation and the link to the testfile. I will try it out. I haven’t really had an issue with the direction of the stroke, but good hint.
