Uncovering the Silicon at Bay Area Maker Faire 2019

We had so much fun introducing visitors to what is inside of integrated circuits last year at Maker Faire that we’re going to do it again! For Bay Area Maker Faire 2019 we are excited to be again joining forces with Eric Schlaepfer and Ken Shirriff, along with our new collaborator John McMaster. We’ll again be bringing decapped chips along with microscopes to let visitors see what’s inside of famous and interesting integrated circuits. We’ll also be bringing large scale reference models. Bay Area Maker Faire is May 17-19 at the San Mateo County Event Center. You can check out our Maker Faire page and we’ll hope to see you there!

Math foods for Pi Day

There are a great many ways to celebrate Pi Day, and food is one of our favorites. While pie is obviously appropriate for Pi Day, there are so many other fun ways to explore math and science through cooking. Here are some of our food projects that can be great ways to explore math concepts on Pi Day:

Happy Pi Day!

AxiDraw on MythBusters Jr

I’m super excited to see the new MythBusters Jr episode tonight, because I’m in it with the AxiDraw!


I had a fun time working with Valerie, Rachel, and Elijah, as well as the great crew.

Plotter People Talk

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.

Many thanks to Plotter People for inviting me to speak!
