MOnSter 6502 and Digi-Comp II at Vintage Computer Festival PNW

We’re bringing the MOnSter 6502 and the Digi-Comp II to the Vintage Computer Festival Pacific Northwest February 10-11 at the Living Computers: Museum+Labs in Seattle, Washington.

Living Computers: Museum+Labs is an incredible museum! Bring your camera, bring your children, and enjoy all that LC:ML and VCF have to offer.

Check out the exhibitor list and the speaker lineup for more information.

AxiDraw, JavaScript, and Generative Art

Matt DesLauriers published a two-part blog post, Pen Plotter Art & Algorithms exploring his JavaScript workflow with AxiDraw and generative art.

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.

He has also posted his source code on github for the articles.

Part 1 covers getting started and explores Delaunay triangulation. Part 2 delves deeper into developing algorithms.

Plotter Portraits

A couple of creative artists, Makio&Floz, are offering custom plotted portraits, drawn by their AxiDraw, playfully named Jojo the robot.

Makio&Floz is a duo working on digital based projects. Without limiting themselves to a virtual space or a physical one, their goal is to explore design and generative art using code as a pencil.

You can upload a photo, preview the “Plottrait”, and order your own custom generative art piece.

Callie’s Crown

Callie's Crown

Last year while attending FIRST robotics competitions with the Firebots, I had the privilege of serving as a judge at both the Central Valley Regional and the Sacramento Regional. Judging gives an opportunity to get to know the folks involved in the competition, whether they’re students, mentors, or other volunteers like you. I’ve judged and volunteered at a few events now, and one of the great things to see is the way that the community builds and nurtures itself.

Neopixel Tiara by Callie

One of the students I met in past years, Callie, had graduated from her team, but keeps coming back as a volunteer. Callie was refereeing at both events, and shines brightly as a role model. Literally. She built an LED tiara and programmed it to light in the event colors of red, white, and blue.

She let me take a few pictures of it. It is made with Adafruit Flora Neopixels, a Gemma controller and a small LiPo battery.

She’s a student at UC Davis, and is a truly wonderful role model for the high school students at the events. While you don’t necessarily need an LED tiara to shine as a role model, Adafruit does have a tutorial so that you can make one, too.

Using the WaterColorBot to teach programming

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.

AxiDraw on Stage

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.

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!
