Woodworking Classes

Personal JourneyDavid WertheimerComment

I’ve always enjoyed teaching, and for a couple years now I’ve been a woodshop instructor at a maker space in Sunnyvale, California: MakerNexus. Along with other instructors, I teach both basic power tool safety, as well as a variety of more advanced skills in longer workshops. Though I’m excited to give back to the community and share my enthusiasm for the craft, I often leave classes with more energy than I arrived with, as my students share their energy and curiosity as they embark on their creative journeys.

Kinetic Gifts & Inspiration

Technology & SteampunkDavid WertheimerComment

While many pieces of kinetic art are installations unaffordable to any but the largest institutions and corporations, I wanted to highlight a few artists and companies that have very creative offerings that can be purchased. I cover a wide affordability range, from $50 all the way to $20,000.

Or if you have a few million to spare, I’ve also highlighted a number of bespoke design firms and designers around the world who can help you deck out your villa or decorate your massive garden… or at least serve as inspiration for your own unique kinetic steampunk and electronic creations.

Ring-Based Message Board

Technology & SteampunkDavid WertheimerComment

Leveraging a bit of the electromechanical experience I’ve garnered on past projects, and scratching that ever-present itch to do some interesting programming, I’ve worked thru much of the design and math for a “ring” messageboard or clock. This steampunk-esque design builds on the principles of a combination lock, can be extended to a message board of arbitrary length, and yet can be set with just a single precision-controlled motor. Read on for the what, how-to, and wherefore!

Upgrading from Steppers to Servos

CNCDavid Wertheimer6 Comments

I swapped out the drive motors on my CNC from steppers to servos; in this post, I go into the details of all the troubleshooting I’ve done over the months before making this costly upgrade. Though it is not necessarily justified for everyone, the improvements I’ve seen in accuracy and performance have made it worthwhile for me, providing the foundation to tackle much more challenging jobs (and to lower my stress level when doing even simple jobs).
