With the software i wrote (see last post) and still test for the KH-940 i now explore the possibilities to knit datavisualisations beside the Nordic knitting technique.
The other techniques are: patent stitch, skip stitch (Dutch slip steek), tuck stitch, jacquard, ajour, lace stitch. It involves all kinds of tricks with the needles.You get a relief, or open stitches, or connections between tours which are far apart.
This post presents first experiments, in later posts teh different possibilities will be explored individually and more in detail, what the knit stitch really is, how to code for it etc.
With a GPS track already shown earlier I prepared the images for different knitting techniques. Because you skip needles or keep thread in waiting several tours you cannot do everything you are used to for “simple” Nordic knitting. Also, because you are “torturing” the needles a bit, better start with not too fancy threads. (I always mix colors and thread, but for instance very smooth thread easily slip of needles.)
A few results:
back of a Nordic knitting
Nordic knitting, image prepared for the following skip stitch and patent stitch
skip stitch giving a nice relief
Another skip stitch (two different threads together)
And a tuck stitch (two different threads together)
Jacquard, (two different threads in seperate Jacquard piece)
The corresponding image (slip stitch style), where you have to “know” which needle position (B or C) is the black pixel, reverse the needle positions (black and white pixels) and disaster strikes…
This is the GPS track again, the most interesting part is the PLA stitches around the track!
Two sides of the same shape, which is the left side of the next image. This is the needle signal of the knitter, knitted again. The slips are particularly “thick” because some double threads were used.
Image of the sensor code of the KH-940, left the needle sensors, right the solenoid (which should cover 8 needles for half of it.) The next image is from the
which can be downloaded from the internet, explaining how the needle sensors keep track of going left or right. It is a bit like walking with two legs, 1,2,3,4, the long stretch is the solenoid counter.
The different techniques require different images. In experimenting you can go wrong, but what is wrong?
really very longs slips, indeed this knitting was a disaster – i have to work on the image, get the right number of pixels next to each other.
Very long connections because of images that are not really fit for the slip stitch technique.
A view of my floor with all kind of experiments:
of course if I am knitting, my 3D printer can work as well. With the Blender possibility of making a 3D shape of an image i explore these datavisualisations further, some of the results closely resemble the knittings, here the MPPT graph, in knitting and 3D print:
(actually mirrored MPPT)
Nordic knitting of the 3D print ( An MPPT graph is the efficiency curve for a solar cell with varying load, for another version: http://etextile-summercamp.org/2014/solar-cell-efficiency-energy-harvesting/
This is the Jacquard patent knitting for the MPPT graph, from another image:
(Since Jacquard is mirroring the image, there should be a button “mirror” depending on the technique used added to the Processing sketch.)
The best for the last: (this kind of visualising i was looking for when starting…)
lace stitch (not mirrored like Jacquard), which is using two threads, one of which is very thin, creating the open stitches:
You see that the threads are not hanging free in these area’s like the Nordic knitting. Further experiments, whith different threads and images are very much required!
The next challenge is adding the L carriage. But then a bit of extra programming is required for the sensor value of the L carriage to have effect on the tour count.
