### Overview
"The World Of DIY Modular" is a guide published by Modulove covering the basics, philosophy, and practical assembly workflows of DIY Eurorack modular synthesis.

### Topics Covered
* **Introduction to Eurorack Standards:** Power rails (+12V, -12V, +5V), pinouts, shrouded headers, bus boards, and safety against reverse power protection.
* **Component Basics & Soldering:** Identifying SMD and Through-Hole (THT) components, resistors, capacitors, IC sockets, microcontrollers, and operational amplifiers (Op-Amps).
* **DIY Assembly Steps:** Step-by-step assembly process from low-profile components (resistors, diodes) to jacks, potentiometers, and front panels.
* **Troubleshooting & Testing:** Multimeter checks, short-circuit testing prior to initial power-up, and power consumption calculations.
