We present a framework in which gravitation, inertia, and wave dynamics emerge from the response of a vacuum endowed with ...

Tommy] at Oskitone has been making hardware synth kits for years, and his designs are always worth checking out. His newest offering Space Dice is an educational kit that is a combination vintage ...

Abstract: We study bipartite synchronization in Schmitt–trigger relaxation oscillator (STRO) networks with signed threshold injection. Under weak coupling, the hybrid RC–Schmitt dynamics reduce to a ...

Multifunctional fluidic units generate coordinated motion and sensing in soft robots by combining actuation, switching, and oscillation in one module, reducing reliance on electronic control.

Try an experiment. Next time you are in a room with someone, ask them to name everything in the room. Only certain kinds of people will say “air” or “light.” For most people, those are just givens, ...

A Planet Analog article, “2N3904: Why use a 60-year-old transistor?” by Bill Schweber, inspired some interest in this old transistor and how it’s commonly used, and if any uncommon uses might exist.

Abstract: This paper introduces a novel non-RC, leakage-based relaxation oscillator designed as a timer in ultra-low-power (ULP) applications. The proposed oscillator structure is created by stacking ...

Editor’s Note: This DI is a two-part series. Part 1 shows how to make an oscillator with a pitch that is proportional to a control voltage. Part 2 shows how to modify the circuit for use with higher ...
