RF engineers put great effort into crafting high quality radio systems. I am not one of those engineers. Experimenting with radio protocols using SDR.

How does life unfold if you create things? Nothing created is wasted — following your dreams will lead you somewhere (maybe not where you planned), but to a good place. How I quit my engineering job and built interesting things as a career.

At the intersection of the two black arts of RF engineering and antenna design is the phased array. But don’t worry, they’re not as hard to understand as you might think.

Showing the process for the construction of vacuum tubes. Tubes will be built and tested on site using glass working torches and other specialized tools

Always wanted to paint like Bob Ross, but have the artistic skills of a wet cardboard box? Perhaps you can be helped by a printer cartridge and some electronics.

Challenging traditional manufacturing techniques used to build orbital class rockets. Here’s how Relativity Space 3D prints rocket engines (104 tests already) and avionics.

“SHE BON” can sense and indicate the wearer’s level of arousal/excitement. It explores ways in which we can use our bio-data to communicate aspects of our being that would otherwise go unnoticed, as well as how technology can help us add another layer of texture to how we express our individuality.

Novel soldering techniques for building art, prototypes, and short hand-built production runs using techniques like SMT cordwood, carved FR4, and small scale free-air.

Learn to design optical elements like diffractive waveguides (Magic Leap, Hololens, Akonia, Digilens), and electronically controlled elements that can changing depth in real-time. More importantly, learn how to make your own with accessible machine shop equipment.

Microcontrollers have lots of built-in functionality that goes unused because long datasheets can be overwhelming. That ends now.
