Digit Shield Used in Concrete 3D Printer


Wow, this is the craziest 3D printing I’ve ever seen. The material is concrete! Andrey has been working very hard for years to developed a 3D printer than can literally print houses. Here is the castle he printed.

Inside the sophisticated controller for this printer is a nootropic design Digit Shield. I don’t know the details of how this all works, but this controller is indeed impressive.

Looks great! Here it is in action:

I’m Featured in the New Book “Maker Pro”!


I’m so happy to be one of the authors of the new book Maker Pro edited by John Baichtal. Maker Pro is a collection of essays by makers who have gone pro by starting their own businesses. Last year John asked me to write an essay about my experiences, and I happily penned a piece called “The Power of Constraints”. In the essay I talk about how I got started making and how the technical limitations and constraints of microcontroller programming were the fuel that fed my fire. It’s a great book, so consider buying it on Amazon. I’m truly honored to be among some great hardware hackers and makers.
