Practical, no-fluff guides for makers, hobbyist electricians, and Arduino builders — from your first solder joint to a fully wired workshop.
Every guide on ElectricalFlux lives in one of three core hubs, with a fourth fundamentals hub rounding out component and tool knowledge.
Irons · flux · technique
Everything from your first soldering iron to flux chemistry, through-hole and surface-mount technique, and side-by-side buyer guides for irons, stations, and kits.
Arduino · ESP32 · sensors
Boards and platforms, real-world projects, sensors and peripherals, plus the coding and communication protocols that tie it all together — from first sketch to production-grade firmware.
Outlets · diagrams · remodels
Switch and outlet wiring, device and appliance wiring diagrams, and full general-purpose wiring guidance for remodels, harnesses, and code-compliant residential work.
Topical-authority fundamentals — electronic components, prototyping, and the electrical tools and test gear every maker and electrician should know.
Soldering Irons & StationsPractical bench zoning, tip cartridge storage, flux organization, and inventory rules for soldering stations.
Comparisons & Buyer GuidesLearn what data means for beginners through soldering examples, measurements, supplier records, and a simple 30-day plan.
Sensors & PeripheralsMCU peripheral design demands rigorous mathematical modeling—but real-world safety-critical systems require far more. This article examines the critical gap between idealized formulas and physical, environmental, and behavioral constraints that govern reliable operation in automotive, medical, and industrial applications.
Coding & CommunicationA practical overview of Raspberry Pi MCU project essentials, including GPIO safety, UART, I2C, SPI, board choices, software tools, and debugging workflows.
Components & PrototypingLearn how to match electronics by comparing voltage, current, impedance, logic levels, thermal limits, reliability, and real measurements across resistors, capacitors, inductors, semiconductors, power supplies, sensors, and microcontrollers.
Boards & PlatformsA no-fluff, precision-focused repair methodology for professional-grade MCU boards — covering diagnostic workflows, soldering standards, BGA rework, firmware recovery, and ESD-safe practices used by Tier-1 contract manufacturers and in-house hardware teams.
Comparisons & Buyer GuidesA data-driven analysis of solder performance across price tiers—covering flux activity, wetting speed, voiding rates, thermal cycle endurance, and long-term reliability. Based on IPC-A-610, J-STD-004B, and 12 years of procurement validation across automotive, medical, and aerospace programs.
Boards & PlatformsA field-proven, measurement-driven guide to soldering techniques that prevent field failures in automotive, medical, and industrial MCU boards — covering thermal profiling, alloy selection, joint geometry, IPC standards compliance, and real-world validation data from 12+ years of failure analysis.
Raspberry PiA precise, engineer-level comparison of binary representation and Arduino’s abstraction layer—covering memory layout, instruction execution, timing accuracy, and real-world tradeoffs using ATmega328P, ESP32, and RP2040 hardware data.
ElectricalFlux is built around three high-volume, low-difficulty content pillars. The Solderinghub covers irons and stations, flux and consumables, hands-on technique, kits and gear, and head-to-head buyer guides — from “what is soldering” to propress-vs-solder comparisons.
The Microcontrollers hub is the largest keyword pool on the site, spanning Arduino and ESP32 boards, real-world projects, sensors and peripherals, and the coding and communication protocols (I²C, SPI, Serial, Bluetooth) that tie them together.
The Electrical Wiring hub is the biggest by search volume and the easiest to rank in: switch and outlet wiring, a deep library of device and appliance wiring diagrams, and general-purpose wiring guidance for remodels and harnesses — all grounded in the NEC.
