Yesterday I gave a talk at the inaugural Plotter People meetup titled Plotter Projects from Evil Mad Scientist Laboratories. My slides were a series of pictures from our projects, so rather than publish the presentation itself, I’m publishing a list of links to all of the projects I talked about.
The first part of the talk was introductory information about Evil Mad Scientist with some example projects from our blog and our early kits.
The main part of the talk delved into all of our plotter related projects, including hacking plotters, things we’ve made from plotters, software we’ve made for use with plotters, and plotters we’ve made.
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!
We’ve just added two new magnetic easels for AxiDraw to our lineup of AxiDraw accessories. They are sturdy work-holding tools that provide an alternative method of positioning paper or other workpieces for use with the AxiDraw. A heavy-duty alternative to the regular clip easel, they can be used with binder clips or the included positioning rulers and magnets.
We’ve just added two new accessories for the AxiDraw V3.
The first of them, shown above, is the XL Pen Clip — something that we’ve had a number of requests for. The pen holder on the AxiDraw normally fits pens and other instruments up to 5/8″ (16 mm) in diameter. However, this new XL pen clip can hold instruments up to 1″ (25.4 mm) in diameter.
That is to say, it can hold things like this freaking huge marker:
The second new accessory is a little more subtle: an Italic Pen Adapter that gives the AxiDraw a “right handed” grip on pens.
It’s a little bracket of anodized aluminum, with captured screws and threaded inserts, which rotates the AxiDraw pen clip 45° out from the X-axis of the AxiDraw. This angle can give a slightly more “natural” look to certain types of handwriting-like plotting.
And of course, it’s ideal for use with various types of blunt-tipped pens, including chisel-point felt tip pens as well as pens with stub and italic nibs.
