Electrical engineering systems
Circuits control current and voltage to perform computation, signaling, and power distribution across components and boards.
What It Is
Electronics is the design and application of circuits and systems using electronic components. On this site, it matters because it transfers across technical, operational, and venture work instead of staying trapped in one narrow context.

Mechanical systems
Physical assemblies transfer force and motion through components such as gears and actuators under constraints of energy, friction, and material properties.
Pro audio/visual systems
Signal chains capture, process, and distribute audio and visual data in real time across consoles, amplification, and lighting control systems.
Radio systems
Information is transmitted through the electromagnetic spectrum using modulation, frequency allocation, and protocol layering under physical and regulatory constraints.
What a Dead Car Battery Taught Me About System Failures
A dead-battery problem that looked random until measurement, isolation, and one small wiring change exposed the real system failure.
Adding an 18-inch Subwoofer to my Tiburon
A stock-minded car-audio build around an oversized JBL subwoofer, a borrowed amp, and the practical work required to make it fit cleanly.
Bluetooth A2DP in my Tiburon
Adding Bluetooth audio to a Hyundai Tiburon while keeping the dashboard and overall look as close to factory as possible.
Arduino
Arduino is a microcontroller platform for building hardware and IoT projects.
Building with Tools and Materials
Working with tools and materials has been part of how I learn to build since junior high shop class first set me on that path.
Compute hardware systems
Physical machines such as CPUs, GPUs, memory, and storage execute instructions under constraints of heat, power, and architecture-level parallelism.
