Leo's bag of tricks


Remote Lounge

February 16th, 2021

We take a trip back in time to explore the legendary Remote Lounge, a surveillance-themed bar/lounge that opened 2001 in New York City.

Dimming The Undimmable Lights

February 15th, 2021

In this video, we explore a method of hacking common mains-powered LED fixtures by adding a small extra circuit. We are then able to convert these fixtures into DALI (Digital Addressable Lighting Interface) controllable lights that can be integrated into an awesome lighting system.

Infrared Rememberizer

October 7th, 2020

This video explores the science of Infrared Remote control, and the design of a simple device to record and playback IR signals - regardless of the protocol used.


Linear Ratchet Clock

October 7th, 2020

This video explores the design and construction of a linear ratchet clock based on a bandsaw blade serving as a linear ratchet.


The Ultimate Continuity Tester

July 2nd, 2020

In this video, we explore the tricky challenges in trying to design an electrical continuity tester that can survive almost any abuse we can dish out.

The Inventors Paradox

April 30th, 2020

In this video, I explore what it’s like trying to develop an innovative new piece of technology. It’s not always glorious, but it’s often delightful. Always remember to enjoy the process and the journey of life.

All Transistor Clock

April 10th, 2020

As a teaching exercise for my “Technology for Artists” class, we designed and built an all-transistor digital clock using no chips of any kind – as if we were back in 1960. (we cheated a little on the display)

Making a Current Transformer from Washers

April 10th, 2020

This is a tutorial showing how to make an AC current sensing transformer out of a handful of steel washers. We also do a deep-dive into the design of signal processing circuitry to make our washer transformer into a useful building block.
