Seymour Papert’s Mindstorms was published by Basic Books in 1980, and outlines his vision of children using computers as instruments for learning. A second edition, with new Forewords by John Sculley and Carol Sperry, was published in 1993. The book remains as relevant now as when first published almost forty years ago.
In computing, a visual programming language ( VPL) is any programming language that lets users create programs by manipulating program elements graphically rather than by specifying them textually. A VPL allows programming with visual expressions, spatial arrangements of text and graphic symbols, used either as elements of syntax or secondary notation.
I’ve been teaching computers to stipple. It’s fun stuff. Stippling: The production of continuous graduations of light and shade through the use of small, discrete dots or strokes. In painting the technique is more commonly called pointillism. New! You can now download executables and source code.
The following information is retained for historical purposes. Adrian Secord has removed his Weighted Voronoi Stippler program from his website. Two other stipplers based upon Adrian’s work and which produce SVG to consider are Evil Mad Science’s StippleGen and http://www.saliences.com/projects/npr/stippling/stippling.html. Unfortunately, there is very little in the way of ready-to-use software packages or plugins for automatically producing stippled images.

SquiggleDraw will create a SVG file from an image, using the brightness to change the amplitude of sine waves. It is easier to look at the examples below to better understand. 🙂 You can use the saved SVG file to print from Inkscape/AI/etc, draw with a pen on a pen plotter (like the awesome AxiDraw), or engrave with a lasercutter (it looks cool!)
Halftone is the reprographic technique that simulates continuous-tone imagery through the use of dots, varying either in size or in spacing, thus generating a gradient-like effect. “Halftone” can also be used to refer specifically to the image that is produced by this process.
StippleGen is a free, open source, and cross-platform application from Evil Mad Scientist Laboratories that can create stipple drawings and ” TSP art,” from image files. One of the perennial problems that we have come across in a variety of contexts, including CNC artwork and producing artwork for the Egg-Bot, is the difficulty of creating good-quality toolpaths- i.e., vector artwork representing halftones -when starting from image files.

This project was developed as part of a TU Vienna Bachelor thesis on the use of L-systems inside of the open source 3D computer graphics software Blender. The thesis describes applications of the code prodived in this project for specific use cases of L-system modeling in Blender and specifically to environmental interaction of a growing structure with a Blender scene.
L-systems were conceived as a mathematical framework for modeling growth of plants. L-Py is a simulation software that mixes L-systems construction with the Python high-level modeling language. In addition to this software module, an integrated visual development environment has been developed that facilitates the creation of plant models.

A Servo Motor can be either a DC, AC or other type of motor and includes a device to know it’s position (ex.: potentiometer, digital encoder…).
Inside most Servo Motors you will find: A motor, gears, some type of limit stops that will limit the movement of the shaft, a potentiometer of some kind for position feedback and some integrated circuit to move the servo to a specific position.
A Standard Servo has around 180 degrees of motion. These can be modified to make them rotate 360 degrees or you can buy them already made this way.
The modification involves opening the Servo case, removing the limiting device and disconnect the potentiometer from the shaft. Once done the Servo will rotate in either direction endlessly since it has no way of knowing it’s position anymore and there are no limit switches to stop it.
Most Servo Motors have three wires:
White or Yellow: Control Wire.
To move a Servo you send a pulse to the control wire. This process is referred to Pulse Coded Modulation.
Standard Servos expects to see a pulse every 20ms. Depending on the length of this pulse the Servo will move to a specific angle.
For example a 1.5ms pulse will make the Servo move to the 90 degree position (which normally is the neutral or middle position).
A pulse shorter than 1.5ms will be move the Servo closer to 0 degrees and a longer one will move closer to 180 degrees.
Servos can have a lot of torque for their size and they also draw power in proportion to how hard they are working. So if you project is not moving much weight than the Servo will not consume much energy.

Viscosity printing is a multi-color printmaking technique that incorporates principles of relief printing and intaglio printing. It was pioneered by Stanley William Hayter. The process uses the principle of viscosity to print multiple colors of ink from a single plate, rather than relying upon multiple plates for color separation.

Gelatine printing is a form of monoprinting in which a gelatine slab is used as a printing `plate’ in conjunction with standard water soluble printing inks/paints to create images. Very little pressure is required to make monoprints using this technique – no press is required.
- slab of glass for ink rolling
- paper/ aluminum foil /plastic – for covering the work space
- removable tape (masking, cellophane, etc. not essential but can be handy)
- water-soluble printing ink , acrylic paint, (Oil-based inks are not advised.)
- something to print e.g. stencils or flat textured objects: plants, feathers, found objects, etc.
To create the gelatine plate
I use 2 tablespoons of unflavored gelatine for each cup of water – food grade Gelatine – (It can be helpful to dissolve the gelatine with some cold water first then add hot to make up the amount.) The finished slab should have a yellow tinge. If the gelatine is too thick I have noticed that it is harder to release the paint/ink – weather conditions also effect this.) The plate can remain in the container (if your paper size is smaller than the container) but if you want to use the edges you need to turn it out and make a plate that is about 1.5 cm thick.
For a more permanent gelatine plate substitute 1/2 the water for glycerine. (eg. 6 TBS gelatine, 1 1/2 c glycerine and 1 1/2 c water)
Smooth is good as any marks will leave indentations. Try shallow baking tins, Tupperware style containers, trays from op shops etc. You can make your own shape by building up the edges with non-drying modelling clay/plasticine around the interior edge of a tray or on a plexiglass sheet. The plexiglass will yield gelatine with two flat, workable sides, but the plate must be level and check very carefully for leaks in your clay dams before pouring the hot gelatine. Larger plates may be made using larger containers, in which case lining the bottom with plastic wrap will make the plate easier to remove.
Pour dissolved gelatine into the mould. Sweep out any air bubbles with paper scraps. Allow the liquid gelatine to solidify by leaving it undisturbed in a cool place (refrigerator, if possible), until it is quite firm to the touch.
When ready, dip a knife in warm water and run it carefully along the inside of the mould, then gently get hands underneath hands underneath lift up, keeping hands wide walk your fingers along length to avoid cracking and ease the gelatine out of the mould.
Smooth is good, thin is good. Use a dry paper. Watercolor papers, especially the hot press ones (Arches is good). Rives BFK, some pastel drawing paper, lightweight printmaking paper, Asian papers, brown paper, and tissue paper. Paj and organza silk pick up with delicacy. Computer and velum paper tend to curl up at the edges once they dry.
Standard water-based printing inks generally dry very fast, typically less than 5 minutes. This is good because your prints dry quickly however the ink/paint may dry too quickly on the gelatine block. It can be useful to add mediums: gel medium to acrylic paint, textile medium to textile inks, transparent base and extender to printing inks.
Many techniques used in traditional monotypes are possible using gelatine as the printing surface. Ink can be applied to the gelatine in a positive manner, using brushes and brayers to develop the image. One great advantage of using a gelatine plate is that ink can be transferred fairly evenly with very little pressure and gelatine is an excellent material for transferring details from found materials.
Squeeze some printing ink onto your palate and brayer it evenly until you have a nice thin coating on the brayer. Brayer the ink onto the gelatine plate gently and evenly. (Or paint on with a brush and even out with a brayer directly on the plate) The ink colour should both suit your subject matter and contrast with your paper in order to bring out the most detail.
Place flat textured object/s on top of the inked plate. Gently press down to be sure there is good contact with the gelatine, but try not to tear, gouge, or damage the plate.
Leave the object/s in place on the plate and lay a piece of paper down on top of it. Rub your palm lightly over the back of the paper to transfer the ink. You don’t need much pressure; gently ensure that the paper makes good contact with the exposed gelatine plate. Peel the paper off. The resulting print is called a negative image. Newsprint can be used like a blotter if you are not so keen on the silhouette image results from this step, or have a spare piece of paper where everything excess gets loaded onto – could be useful for wrapping paper.
Continue by gently lifting the textured object/s off the gelatine. You will see some texture imprints which will appear in your monotype. Lay a fresh dry piece of paper/fabric down on the gelatine plate and run your hand over gently, again to ensure a good contact between the paper and the gelatine. Slowly peel the paper off. This print is called a positive image.
Gelatine has a natural suction to it and ink transfers quickly and easily. As you continue to work with the gelatine, it starts to give off moisture, which mixes in with the inks, adding fluidity and translucency, resulting in painterly, fluid-looking prints. While the plate can be cleaned and used several times, it will eventually start to break down. After much use, it can crack, crumble, and develop texture, all of which give interesting effects in your prints. These irregularities and surprises can give you the opportunity to think of some of the printmaking session as drawing.
start with a flat application of color, making layering a part of the image from the beginning. (Use a bit of masking tape to fix your paper down on one end to help with registration) As the image develops and some areas become complete, they can be blocked out with a homemade stencil of cardstock or mylar, and you can continue developing your image on the uncovered areas of the plate. You can cut your own stencil shapes, or even incorporate store-bought stencils into your prints. I like using the boldness of stencils with something more detailed, like fabric mesh.
The gelatine plate is quite cold when it comes out of the refrigerator and moisture will condense on it for the first 20 or so minutes of use. You may find that your first prints are a little bit runnier than your later prints or you may need to wait until the plate dries up slightly. As the plate warms up, it will become more and more `mushy’ and may start to fall apart. Chilling the plate after 2 or 3 hours of use helps to restore its firmness.
If you tear the edges, just cut away with a knife till you have the shape you want.
I cut stencils out like this – photocopy (or draw) a simple silhouette onto the middle of a sheet of mylar and then cut around the image with a soldering iron. Do on a glass surface. My soldering iron is a textile one – it has a fixed temperature and a fine point.
Clean the plate: you can use a piece of newspaper to pick up extra ink left behind, or use a slightly damp sponge. I clean mine with baby wipes! The plate may look coloured but you can print other colours on it after cleaning.
- Negative-on-positive, positive-on-negative
- Printing negative images on top of positive images and vice-versa.
- Apply ink to printing object
- Apply small amounts of ink, either with the brayer or your fingertips, to an object before pressing it onto the gelatine plate.
- Different papers – different types of paper will absorb the ink differently and reflect the technique differently. I like using white paint on black paper for strong imagery.
- Experiment with different brands and types of printing ink, paints, dyes, etc.
- Tempera paint is particularly well suited for young children. Be sure that all colorants are water soluble! Many recommend Akua Kolor.
- Use the plate like a rubber stamp – cut the plate into pieces, ink them, then pick them up and print on surfaces as if you were using a rubber stamp.(It’s easy to see where you are stamping as you can see through the gelatine!)
- Do a woodblock/screenprint print over the top.
- Alternative media – try fabric, painted surfaces, wood, egg shells, etc.
- Gelatine can even be used as a material for relief printing, cutting, gouging the plate. It must be handled carefully, and it won’t stand up to editioning.
- Pour gelatine onto one of your etching plates to create a flexible stamp.
Gelatine er et naturprodukt af animalsk oprindelse. Det fremstilles udfra kollagen, som er er protein og en vigtig bestanddel af bindevæv. Gelatine kan derfor udvindes fra hud, sener og knogler. Omdannelsen fra kollagen til gelatine består i en ændring i molekylets struktur, som f.eks. vil ske ved opvarmning. Gelatine er i modsætning til kollagen vandopløseligt, og ved afkøling vil der derfor dannes en gel.
Den industrielle fremstilling af gelatine er typisk af hud, sener og knogler fra svin og kvæg, men kan også bestå af råvarer fra andre drøvtyggere (får og geder), fjerkræ, fisk og vildt.
Først foretages en knusning af råvarerne, hvorefter der foretages en grundig affedtning. Dernæst behandles råvarerne i saltsyrebad i flere dage, hvorefter gelatineproduktet ekstraheres (udtrækkes) fra knogler, huder m.m. med syre og så behandles gelatineproduktet i basisk væske i flere uger. Derefter foretages ekstraktion i varmt vand. Endelig bliver gelatineopløsningen filtreret, koncentreret og steriliseret ved 140°C før den endelige tørring af produktet.
Teknologisk har gelatine flere egenskaber som for eksempel emulgeringsmiddel, geleringsmiddel, bindemiddel og fortykkelsesmiddel. En lang række forarbejdede fødevarer som f.eks. kødpålæg, kager, desserter og slik, herunder vingummi, indeholder gelatine.
gelantine er også kendt som husblas for forbrugerne….

Take a look at the image of a square next to a circle. When the circle is mathematically the same height as the square it appears to be too small… to counteract that the height needs to be increased slightly so it looks correct to the human eye. This height increase is called ‘Overshoot’.

Inverting files isn´t always straightforward:
As you can see from the image above when black on a white object is reversed we experience what’s known as irradiation phenomenon, whereby the white version looks 10% larger. To counteract this illusion, it’s important to slightly reduce the overall weight of the logo.

The conventional view holds that girih (geometric star-and-polygon) patterns in medieval Islamic architecture were conceived by their designers as a network of zigzagging lines, where the lines were drafted directly with a straightedge and a compass. We show that by 1200 C.E.
To create even easier ornaments, than with the laser cutted Girih tiles, I decided to write a specialized App for it. An App has some advantages to the physical tiles: Physical tiles tend to move around a bit, when you release your fingers or add another piece.
Girih tiles are a set of five tiles that were historically used in the creation of ornaments for decoration of buildings in Islamic architecture. This browser app allows you to:
- Lay Girih patterns on an infinite canvas.
- Color and style your design.
- Export as vector images.
Girih tiles are a set of five tiles that were used in the creation of Islamic geometric patterns using strapwork ( girih) for decoration of buildings in Islamic architecture. They have been used since about the year 1200 and their arrangements found significant improvement starting with the Darb-i Imam shrine in Isfahan in Iran built in 1453.

Tsubaki Abura – Camellia Oil
Camellia oil is applied to the barengawa (the bamboo sheath on a baren) to keep it supple and prolong its life. The oil may be applied with a saturated pad, cotton ball, or use the palm of your hand. Rub just a drop or two of oil into the sheath, paying attention to the sides as well as the face of the barengawa.
Imported from Japan, our camellia oil comes from camellia japonica seeds. It is cosmetic grade and used in Japan as a hair and skin moisturizer, so it is good for your skin as well the barengawa.
The oil will also protect cutting tools from rust. Apply a small amount to the steel blade after sharpening it on water stones.
Disk Baren This high tech plastic baren was designed by the famous Japanese relief printmaker, Akira Kurosaki. The replaceable disc has tiny bumps on the surface that apply pressure evenly across the paper as you print. When these bumps wear down after extended use, you can simply remove the old disc and press on a new one.
This neutral pH rice starch powder is made from glutinous rice, so mixing and
cooking it on the stove is not necessary. If your tap water has a high mineral content, use distilled water instead.
1. Place 3 tablespoons of rice starch powder in 1 cup of boiling water.
2. Stir briskly with a wire whisk until smooth. If there are lumps left, pour the hot mixture through a strainer and discard the lumps.
3. Cool before using. The rice paste will thicken as it cools. This recipe will produce a paste that is about the consistency of heavy cream or yogurt.
For a thicker paste, use 4 tablespoons of rice starch; for a thinner paste, use 2 tablespoons.
If you prefer to cook the paste, this recipe is from The Art & Craft of Woodblock Printmaking.
1. Mix 2 tablespoons of rice starch with 5 dl (3½ tablespoons) cold water
2. Stir until smooth and milky
3. Bring 150ml (2/3 cup) of water almost to the boil
4. Add the paste mix in a smooth ribbon while stirring
5. Bring to a boil and keep stirring constantly until the mix goes translucent (about five minutes)
6. Cool, stirring from time to time
The mixture will thicken as it cools. If it is too thick, thin with water. If it is too thin, make a new mixture

Nori is very important in the Japanese style of printmaking. It works as a dispersing agent to give the ink body so it will spread evenly over the block. Ink without nori can look speckled when it is printed, often an unwanted effect, while ink with nori prints more uniformly. Traditionally, it is also used to paste the original drawing to the block.
Nori can be used for chine collé, book repair, and everyday paper pasting jobs. It is smooth, has a pleasant scent, and will not stain. Water reversible, nori is acid free, strong, and because it contains a very tiny amount of formalin, it does not spoil.

The kento is a simple device by means of which the printer insures the register of the picture throughout the printing process. It has been employed for several centuries, and experience has proved it to be the best means for the purpose. The principle is to maintain with absolute exactness the width of the margin of every requisite block by means of two small projections, the kagi (key) and the hikitsuke (draw stop), which are cut directly on the block, as shown in Figure 1. These guides cut on the key block will be printed on the kyogo (proofs pulled from the key block) and therefore copies on every color block, keeping the margin the same width as that of the key block. The printer positions his paper so that its edges coincide with these guides during printing. The kagi is a right-angled guide at the lower right-hand corner of the block; the hikitsuke, a straight-line guide…at a short distance from the lower left-hand corner. To cut these guides, the carver uses the kento-nomi,(a 15mm chisel) the edge of which is strongly made with a wider angle and is perfectly straight. The kento-nomi is held by the grip in the right hand, resting upright on the board with its edge exactly at the line to be cut, in such a manner that the flat side of the tools is vertical to the surface of the board (Figure 2). Then it is pressed down to make a cut about one-eighteenth of an inch deep. After the necessary lines have been cut in this way, the space must be cleared with an aisuki(bull-nose chisel) of large size. The clearing must be very shallow and must produce a flat and smooth surface in order to facilitate the fitting of the paper during printing. The depth required is two to three times the thickness of the paper to be used. In making the kagi, the cleared part must slope very slightly toward the point of the right-angled corner. The hikitsuke is left in the form of a sort of step, the top of which is cut in a straight line. The detail of these two guides can be seen in Figure 3a and 3b.

Pre-loaded with the latest GRBL firmware v1.1. GRBL V1.1 PWM compatible. (Open source firmware that turns G-code commands into stepper signals). Uses removable Pololu A4988 compatible stepper drivers.
DRV8825 allows higher resolutions by allowing intermediate step locations, which are achieved by energizing the coils with intermediate current levels. The resolution (step size) selector inputs (MODE0, MODE1, and MODE2) enable selection from the six step resolutions according to the table below:
- Simple step and direction control interface
- Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
- Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates
- Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
- 45 V maximum supply voltage
- Built-in regulator (no external logic voltage supply needed)
- Can interface directly with 3.3 V and 5 V systems
- Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout
- Short-to-ground and shorted-load protection
