  How to thread the Global 3200-AUT. Or ask at the fabric station.

  The fictional theory of carrier bags

mywdka

Takes real craft skills that I dont currently have 😬 Will need to work on this if planning to use it as a skill. They also have a heavy duty machine for leathers etc. and heavier threads. I love how it is soft and flexible, this doesn't often show up in my work (except prints on fabrics) so definitely interested to explore further.

  Lasers cutting

mywdka

Nice potential for control panel fabrication from acrylic, wood, etc. CNC milling machine for bigger parts but cant cut metal unfortunately (which is so much handier for grounding reasons). Lasercutter is super quick though so probably good for prototypes. Can cut greyboard which seems v interesting, as well as possibility to experiment with materials. Made some text pattern thing on faux-rubber bracelets which took maybe an hour to kiss-cut, while simpler cuts were under a minute.

#f00 0.01mm stroke = cut
#00f 0.01mm stroke = kiss-cut
#000 fill (and everything else) = engrave/etch

20220929 Paper making

• 

  a press squeezing water out of freshly poured paper, water being reclaimed

• 

  handmade paper from plant matter, waste paper and rainwater

Paper is made from paper

Wilco from the Publication Station.

Paper making is super fun just because it is. With Spin and the Publication Station. It uses a lot of water even on this small scale so nice to consider using rainwater, as well as possibly reclaiming the water from the process. Remember to soak pulp overnight if doing it again. Also fun fact paper from wood was only popularised in the mid 1800s (before that made from cotton).

20221005 3D printing

  a fuzzy house

mywdka [Notes on Volumetric Regimes] [[1]]

Another vector machine forced into raster labour. The slicer (eg Ultimaker Cura) is a piece of software that takes a volume, usually in a .obj format, and converts it into a movement or path or noodling-strategy or dance or .gcode file. But this noodling is always in the form of a raking across the xy plane, which is then repeated and layered in the z axis.

'Raster' meaning screen, rake, scrape.

'FullControl GCode' is an interesting name because it offers full freedom in the xyz space.

20221011 Embroidery

mywdka

A digital emboidery machine, if you give the software closed paths it can generate some interesting fill stitches as well as stroke stitches.

The PES filetype is proprietary and closed! There is an online converter (and viewer) that lists gcode as a possible translation, I wonder if an inkscape extension could bypass the proprietary stuff: https://inkscape.org/~Kaalleen/%E2%98%85inkstitch-embroidery-extension also this URL has a star in it :O

wiki

1st workshop on the appropriation, modification and intervention on an (home) appliance (WAMIA). A new friend called Thunder who is a Roomba that listens to (and plays) MIDI notes sent over WiFi.

Also liberating home appliances from their exploitation.

20230221 DSP Workshop

Workshop with Joseph about Pure Data and DSP in general. Pure Data is nice, it uses a graphic patching environment like Max.

I made a sort of FFT resynthesis effect roughly following this tutorial.

We also had an interesting dicussion about variable sample rates and compression, could you have vector sampling? More like approximating the curve or simplifying the number of points on the path.

More amps = good
More volts = really bad

Trying to send microphone signal to an LED strip. But the microphone is really noisey I think? Also a potentiometer controlling the green channel.
