The GPIOs are protected by internal diodes, normally reverse-biased and connected to the power rails – 3v3 and ground. In the case of “5v –> 10k Pull-up Resistor –> GPIO –> Button –> GND”, when the button isn’t pressed, current from the 5v through the 10k goes into the GPIO and through the internal diode to the 3v3 rail.

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.

CREATING YOUR IMAGE
DRAWING MATERIALS Ball Point Pen, Sharpie or Permanent Marker, China Marker/ Litho Crayons, Photocopier Toner (Must be heat-set in an oven or on a hot plate at 225º – 250º for 10 minutes.)
PHOTOCOPIED AND DIGITAL IMAGES
Using Adobe Photoshop and a laser printer you can easily scan and print images onto polyester plates. A 1200dpi laser printer such as an HP 5000, a GCC Elite XL or a Xante printer will work best. However, it is best to make a few adjustments to your print settings to make polyester plates print easily and accurately at the press. By default most laser printers will print images over 133 lines per inch. Lines per inch (lpi) is a measurement of how many lines of small varying sized halftone dots are used to create the illusion of a continuous tone image. Since printing these plates by hand requires more ink and pressure than offset printing, which is what these plates were intended for, we need to decrease the lpi to 75. If you did not do this, the ink sitting on top of all the very tiny halftone dots would likely run together, or ‘bridge’. To prevent this from happening, lower the lpi to maintain a balance between the amount of ink that is needed to print and the space around the dots to hold water that repels the ink. As you gain more control over your printing the easier it will be for you to print higher lpi images. 95lpi is ﬁne for hand printing, but can still be manageable. Another good thing to keep in mind is the size of your image. Although the plate size may be 11×17” or 13×19”, it can be difﬁcult to ink an image that covers almost the entire plate. I would recommend at least 1” margins on each side and printing no larger than an 9×15 image on an 11×17” plate, and a 11×17” image on a 13×19” plate. These are the steps you should follow to properly image your polyester plates:
- Check your Page Setup. MB > File > Page Setup…
Set the Format to the printer you are using and the Page Size to match the size of the polyester plates. Orientation (portrait or landscape) should also be set at this time.
Set your Printing Options MB > File > Print with Preview…
Use this dialogue box to ﬂip the image so it will be backwards on the plate by checking the ‘Emulsion Down’ box. This is also where you will access the Screen settings to change the lpi of the printed image. Set your Halftone Screen’s Lines Per Inch to 75. Angles for 4 Color images: Black/Darkest Color: 45°, Cyan/Next Lighter: 15°, Magenta/Next Lighter: 75°, Yellow/Lightest: 90°.
Set the image Quality Settings MB > File > Print
Load your polyester plate into the manual feed tray on the printer and click Print. Viola!
PRINTING YOUR PLATES
• Printing Paper, Newsprint
• Two Bowls one ﬁlled with 1 L water and 30ml Gum Arabic
• One large sponge cut in half
• Felt & Toothpaste
• Inking Brayers
• Lithography Inks: Black(Graphic #1796), Handschy Yellow, Magenta, Cyan, White, Tint Base/Transparent Base
• Magnesium Carbonate or #8 Varnish.
Prepare newsprint, and printing paper, making sure to add the ‘T’ and Bar registration marks on the back of the paper. Mix and modify your inks as needed and roll out your slab of ink with the brayer. Fill one bowl with about 1L water and 15ml of Gum Arabic. This will help reduce the Ph of the water. Ideally, polyester plates work best with a dampening solution between 5.5 and 4.5 Ph, but I ﬁnd that the small amount of Gum Arabic in the water is adequate. Rinse your sponges. Setup the press, checking pressure, and registration on your plates.
MIXING AND MODIFYING INKS
Polyester plates print best with inks that are moderately stiff with a fair bit of length. True lithographic inks for hand printing are very stiff and moderately short. An ink such as Daniel Smith’s Crayon Black is too stiff for polyester plates and should be modiﬁed by adding a lighter varnish, such as #3, or by adding Handschy CS800 transparent base to make it more pliable for printing these plates. The Graphic Chemical Litho Black #1796 works well, but may need a small amount of mag or #8 varnish. Color Litho inks, such as the Handschy line of inks, may work well out of the can but will often need to be modiﬁed with Magnesium Carbonate. Slowly fold it into your ink until it is mixed in well and then check the consistency to determine if it is correct. It should hold its shape as it sits on the slab rather than immediately relaxing into a blob. If the pigment ‘bleeds’ from your ink while printing, such as it will do with magenta and cyan, adding #8 varnish or body gum to the ink will help greatly. Color mixtures using mostly Handschy Tint Base will require more mag.
Printing using an etching press
To print on the Brand etching press, set the pressure to –1|0, so the roller is just in contact with the press bed. It is easiest to ink your plate on a separate glass slab before printing. Once it is inked, place the dried plate face up on the center of the bed and your paper face down on the plate. Cover the plate and paper with 2 sheets of newsprint. Place a tympan on top and run them through the press. Felts are not needed.
Printing using a litho press
To print on a litho press, lay your plate centered and face up on the press. Place your paper on the plate according to your registration marks, and cover with two sheets of newsprint. Cover with a greased tympan and print. You should only use as much pressure as needed to pull a good impression. The plate will break down quicker if excessive pressure is used. Before you print, set up the litho press by centering your plate, setting the pressure, and marking your start and stop points (traverse marks).

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. It is a fine art printmaking technique, making original prints in limited editions, as it is slow and allows too much variation between proofs to make large editions feasible.

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….
This is an ongoing project as I learn gilding techniques and better comprehend their application. As part of my own experimentation I have used supports that I am likely to use in a real application, 230gm pergamenata and 100lb Strathmore Bristol Vellum.
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.
