cnc lathe

Dan Gelbart shows his home-built air bearing CNC lathe and grinder, which reaches about 1 micron accuracy. He demonstrates the machine and its parts.

A short promotional video of a 5-axis CNC machine milling an elaborate helmet, made by DAISHIN SEIKI with a DMG machine and hyperMILL CAM software. It shows what 5-axis machining can produce.

Machine Thinking traces where mechanical precision comes from, from flat surface plates and the three-plate method up through lathes and early measuring tools. It is the first in a series on recreating the first micrometer.

Machine Thinking argues the 1751 machine, a metal-cutting lathe associated with Vaucanson, triggered the biggest explosion of wealth in history by enabling precise manufacturing of other machines.

CNLohr maps Wi-Fi signal strength at high resolution by moving an ESP8266 on a CNC mill, then visualizes the 3D data in WebGL. The result shows interference patterns in space.

Steve Jobs demos NeXTSTEP Release 3, showing the object-oriented development environment and UI that later became the basis of Mac OS X. Midway through he builds a database-backed GUI app with Interface Builder and Enterprise Objects Framework with almost no code.

Kelsey Hightower's opening keynote at KubeCon, delivered as a live-demo style talk about Kubernetes and cloud-native tooling.

Ted Young of LightStep proposes trace testing, using distributed tracing data to unify testing and observability. The KubeCon-era talk argues for testing against trace data rather than treating tests and monitoring separately.

Matthias Wandel shows how his pantorouter, a template router machine, works. The flexible machine cuts joints such as mortise and tenon and dovetails, and plans are available.
