Stroboscopic Ornaments

Jiří Zemánek, whose EggBot work we have featured before, sent in this wonderful video of stroboscopically animated Christmas ornaments.

The stroboscopic patterns are designed in MATLAB and drawn by EggBot Pro on colored glass Christmas ornaments. Motion of the balls is controlled by custom mechanism built using components from two Prusa i3 MK3 3D printers, like six stepper motors and two Rambo boards. On top of designing the patterns, which is Jiri’s hobby (when he is not busy with research) and building the whole contraption in a very short time, the team had to deal with issues including non-spherical ornaments, or how to use Rambo board to precisely control the velocity profiles.

We love to see how people make things, and Jiri did not disappoint, sharing process photos of making the rotation mechanisms.

With great help from his colleagues Martin, Krištof, and Filip they took Christmas ornaments to the next level and taught them to dance!

The final setup shot captures how they created such a beautiful video.

Merry Christmas to Jiri and the Advanced Algorithms for Control and Communications group! Thank you for sharing your project!

PCB Etching with AxiDraw

Patricio Gonzalez Vivo has been using AxiDraw for circuit board etching experiments.

He draws on copper clad boards with a Sharpie marker with the AxiDraw.

Drawing is followed by a chemical bath.

The marker is cleaned off of the remaining copper to reveal the design. It came out beautifully.

If you’ve used the AxiDraw for marker masking for etching, we’d love to hear about it!

Science Hack Day SF

I will be at Science Hack Day SF giving a lightning talk on Creative Off-Label Tool Use featuring some of the cool and unusual ways people are using AxiDraw and other tools we make. I’ll also have an AxiDraw in the hardware hacking area to play with.

Science Hack Day is October 27-28 and is free, so register now!

P.S. If you’re doing something interesting and science or research related with your AxiDraw, please let me know!

Invisible Ink with AxiDraw

Joanie LeMercier has been working on a project using invisible ink and different lighting schemes with the AxiDraw. He has posted a bunch of clips and pictures in his twitter stream with the heading “Invisible drawing.”

Head over to the thread where you can see more progress shots as well as completed drawings.

The AxiDraw SE/A3

AxiDraw SE/A3

We’re very pleased to introduce a new member of the AxiDraw family: the special edition AxiDraw SE/A3. This new model joins our existing models including the AxiDraw V3 and AxiDraw V3/A3.

Like the AxiDraw V3/A3, the AxiDraw SE/A3 has an XY travel suitable for use paper up to 11×17″/A3 size. However, in place of the central extrusion that makes up the body of that machine, the AxiDraw SE/A3 has a central beam that is CNC machined from a solid billet of 6061-T6 aluminum, and then anodized to a sleek black finish.

This heavy, rigid structure — it’s a solid block of metal! — provides dramatically better straightness and stiffness, even compared to the already-stiff AxiDraw V3/A3. This design adds mass exactly where you want it: to the non-moving base that forms the X-axis of the machine. In order to keep the weight light where it matters, the moving Y-axis of the AxiDraw SE/A3 uses the same stiff and light custom aluminum extrusion that we use on the AxiDraw V3/A3.

We made a video showing off the SE/A3, and how it’s made:

The AxiDraw SE/A3 is available to order now at the Evil Mad Scientist shop.

CMYK Portraits with AxiDraw

Spongenuity has been posting some wonderful portraits made with AxiDraw on instagram, including some CMYK ones like the one below.

AxiDraw on t-shirts

We’ve seen a bunch of posts about using AxiDraw for fabric lately!

Fabric makers and sharpies are both making appearances.

Wooden signs with AxiDraw

Jonathan sent in pictures of these wooden signs he made with his AxiDraw.

He shared some tips as well:

  • Put plastic wrap over the surface to test font, spacing, and size.
  • For polyurethane and lacquered finishes, if you make mistake with a permanent marker, write over your mistake with a dry erase marker and it comes right off.

It is awesome to see people taking advantage of AxiDraw’s ability to draw on different surface materials. Thank you, Jonathan!
