Using the WaterColorBot to teach programming

Water color painting titled Ocean Woman
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.

He has also documented and shared his code on github.

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.

Gravitrack marble machines by Solarbotics

GraviTrack

Gravitrack is a fantastic new build-it-yourself desktop-scale marble machine kit from our friends at SolarBotics, and available now at our store.

Gravitrack is available in two versions: A no-soldering battery-powered version (shown above), or a soldering-required solar version. We also still carry the original SolarBotics Marble Machines, in battery and solar flavors.

Happy Halloween!

Paintings of skulls made by WaterColorBot

I also thought you might enjoy seeing the design we were running today in the classroom…

Spencer Yonker sent in these skull paintings made by WaterColorBot in the classroom.

Halloween!

And we had a customer stop in the shop to show off his red velvet skull, with added flickering LED eyes.

Thanks to both of you for sharing your Halloween spirit with us! And Happy Halloween!
