Bike bells with AxiDraw

Alexandre wrote in to share how Guna is using the AxiDraw for making their collection of vibrantly decorated bicycle bells.

The top part of the bells is screwed on a purposely made acrylic fixture. I have some risers so that the AxiDraw sits just above the bells. They are painted with Posca pens and then receive two coats of clear varnish.

We love to see how AxiDraw gets used, especially when we get to see the fixtures people make for drawing on unusually shaped objects.

Thank you to Alexandre for sharing these process pictures with us! Their beautiful bells are available through Etsy as well as in select bike stores in Portugal.

Designing with EggBot

Our friend Fran posted this great example in the Eggers EggBot Facebook group of one of the things the EggBot excels at: placing a design evenly around any size of egg.

This time a medium sizes rhea egg with three six petal flowers. What I love about the EggBot is that I can get 3 equal flowers onto any sized egg.

After marking the egg with the EggBot, it gets painted and any decorations such as crystals, beading and figurines are added. She also incorporates 3D printed bases into her designs.

Number Systems Plotter Art

Arjan van der Meij recently got an AxiDraw and has been exploring binary and ternary numbers as a plotting subject. It has been fascinating to watch his iterations on twitter and instagram. One of his earliest posts represented eight bit binary numbers as rotated squares.

He started a plot of twelve bit binary circles, but didn’t complete it due to lack of clarity. It is not too often that you get to see this type of artistic decision making in progress– many artists only post the “keepers.”

Speaking of keepers, this one involving six bit binary crossed lines was liked well enough to be replotted on notebook cover. In a further exploration of this style, he also made a 1024 grid of ten bit binary crossed lines.

This post of eight bit binary triangles explored order as well as form with a sequenced as well as a shuffled version. Nested binary shapes, like these triangles and six bit binary hexagons seem to have provoked a jump to a slightly different plotter format: laser cutter.

Some of the forms tried in wood were binary squares, eight bit binary triangles, and the seven bit binary hexagons shown above.

The jump to wood gives rise to a form that seems a bit like a jigsaw puzzle, especially when you see the individual pieces before they’ve been arranged for display.

He explores rounded shapes his series of binary flowers, including six bit binary flowers, ten bit binary flowers, and eight bit binary flowers made of ellipses.

Moving beyond binary, ternary digits have three possible values. I found the nested ternary rectangles/squares and ternary elipses (above) to be straightforward to decipher. Another method explored includes line segments, either straight or with indents or protrusions to express the values as in these ternary squares, ternary hexagon/star/circle, and ternary triangles. Other shapes are harder to describe, like folded ternary hexagons, or ternary squares with their segments folded inwards or outwards in triangles.

It is fun to compare how different number systems can be visualized using similar structures. The eight bit binary “stick figures” are not dissimilar from these six trit ternary arcs on a sticks: bits are displayed on both halves of the figure, whereas the trits are shown inline. Similarly, this set of ternary flowers bring to mind some of the the binary flowers mentioned before but have a different character for carrying more information.

One interesting diversion from the geometric forms he pursued was the text of binary numbers plotted in sequence, creating geometric patterns in the repetition of the letters. He has continued exploring various ways of visualizing and arranging numeric representations, and I’ll look forward to his continued works. If you’ve enjoyed these tastes of what he’s doing, he also posts timelapses and short videos of the process, and is making his plots available for sale on his website.

WaterColorBot on Cool Tools

Donald Bell of Maker Update was recently on the Cool Tools podcasts, and gave the WaterColorBot a very nice shoutout. He also mentioned Turtle Toy, which is a tool for creating your own generative art using a minimalistic Turtle graphics API. We recently found Turtle Toy as well, and have been inspired by the art people are sharing there.

Names Dress

The Names Dress is a compostable 3D printed conceptual art piece celebrating women in STEAM (Science Technology Engineering Art and Math) by Sylvia Heisel. It will be on display at Museo Salvatore Ferragamo’s Sustainable Thinking exhibition in Florence, Italy through March 8, 2020.

While there are increasing numbers of women embarking on careers in STEAM (including inventors, mathematicians, scientists, artists using technology and others), the achievements of women in these fields are not always widely known or celebrated. The Names Dress is a tribute to women, known and unknown, historic and contemporary, in these interconnected and evolving fields. The Dress is also an exploration of the use of sustainable materials and techniques in creating innovative textiles and garments.

The Names Dress website includes a list of the women named, along with biographic information and links to their work. As a starting place for learning about women in STEAM, it is a thought-provoking resource. I’m honored to have my name included on the dress.

Uncovering the Silicon at Bay Area Maker Faire 2019

We had so much fun introducing visitors to what is inside of integrated circuits last year at Maker Faire that we’re going to do it again! For Bay Area Maker Faire 2019 we are excited to be again joining forces with Eric Schlaepfer and Ken Shirriff, along with our new collaborator John McMaster. We’ll again be bringing decapped chips along with microscopes to let visitors see what’s inside of famous and interesting integrated circuits. We’ll also be bringing large scale reference models. Bay Area Maker Faire is May 17-19 at the San Mateo County Event Center. You can check out our Maker Faire page and we’ll hope to see you there!
