Unlike a typical printer, a plotter produces prints with a strangely human quality: occasional imperfections arise as the pen catches an edge or momentarily dries up, and the quality of the ink has the subtle texture and emboss that you normally only see in an original drawing.
JR has been volunteering in a high school programming class and wrote up a thoughtful post about his experiences using the WaterColorBot in the classroom. He wrote a Python library that allows users to directly control a WaterColorBot by writing Python code.
To be honest, this library is a pretty insane way to control the bot. It’s needlessly low-level: you’re manually controlling the brush’s position, you’ve got to remember to wash and re-ink the brush every so often, etc. If your main goal is to just get the bot to paint a pretty picture, there are lots of better ways to go about it.
As a teaching aid, though, it’s been a total success, because it lets students flex their burgeoning Python skills and actually make a real thing in the process! We’ve been blown away by the stuff our students have created.
In unusual uses for our drawing machines, AxiDraw is playing the role of the master of ceremony in Joël Maillard’s play “Last sheet (after the big lack)”, a production about the robotic future being put on by Theater Marie in Switzerland.
Matthew Ragan has been taking advantage AxiDraw’s ability to draw on just about anything, and plotting over already printed materials. He also has published his tools on github for getting vectors out of TouchDesign. He describes it as:
A pipeline for handling the SOP to SVG pipeline. This is especially handy for using procedurally generated geometry for paths to be cut or plotted.
The precious metals used to repair the dishes are used to trigger sound or light, encouraging the participants to connect with the dishes in interesting ways. There’s much more detail on this intersection of craft and electronics over in Vanessa’s post about the workshop.
Our friend Arjan van der Meij made this charming musical instrument from a signal generator, a servo motor, an Arduino and a processing program. He wrote an instructable for it so you can build one, too.
He also wrote about his experience with the project in Dutch on makered.nl. Projects like this one, that started with a question (“Why don’t you build a machine to do it?”) are great for learning new skills. I often get asked what things someone should get for learning electronics, and my answer is usually that the first thing you need is a project that you want to make so that you’ll have motivation to research what you’ll need.
Arjan wanted to learn tinkercad, and used this project toward that goal by modeling the knob adapter he’d need for connecting his servo to his signal generator knob. Even if you don’t want to make a musical instrument from a signal generator, this project may provide inspiration for trying out new techniques.
