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.
General Wiring & ProjectsA field-tested reference for engineers, technicians, and hobbyists covering AWG sizing, insulation types (PVC, FEP, silicone), temperature ratings (60°C to 200°C), voltage classes, conductor stranding, UL/CSA/IEC standards, and real-world performance data from Belden, Alpha Wire, and TE Connectivity.
Tools & Electronics GuidesA field-focused procurement guide covering real-world tactics for evaluating vendors, verifying specifications, managing logistics, and ensuring compliance during on-site purchases—backed by industry benchmarks, brand-specific data, and actionable checklists.
Projects & AutomationA no-fluff, engineer-to-engineer guide to selecting, storing, and using solder consumables for microcontroller-based hardware development — covering alloys, flux types, wire gauges, safety data, shelf life, and real-world performance metrics from 10+ years of lab and production experience.
Coding & CommunicationA field-tested, no-fluff reference for embedded engineers working with microcontrollers — covering clock configuration, peripheral initialization, ISR best practices, low-power modes, and debugging pitfalls using STM32, ESP32, and nRF52840 platforms.
Soldering Irons & StationsA practical, data-driven guide for electronics hobbyists and technicians seeking reliable temperature-controlled soldering irons under $120 — featuring real-world testing of Weller, Quick 205D, YIHUA 936 clones, and KSGER T12 variants, with thermal response benchmarks, longevity data, and mode-comparison tables.
Raspberry PiA field-tested analysis of the top MCU selection errors—from power budget miscalculations to peripheral mismatch—based on 200+ embedded deployments across industrial, medical, and edge-AI applications.
Projects & AutomationA practitioner’s analysis of measurable microcontroller trends for 2026—covering silicon shipments, power efficiency benchmarks, AI-at-the-edge adoption rates, security certification timelines, and real project cost curves from STMicro, NXP, Infineon, and Microchip.
Comparisons & Buyer GuidesA field-tested, specification-driven guide for procurement managers, electronics engineers, and contract manufacturers selecting soldering equipment—covering iron tips, temperature stability, power delivery, ESD safety, and real-world compatibility with J-STD-001, IPC-A-610, and RoHS-compliant workflows.
Comparisons & Buyer GuidesA field-tested, data-driven guide to soldering iron operating modes—temperature control, power delivery, and thermal response—featuring real-world performance metrics from Weller, Quick, JBC, Hakko, and Pace. Covers mode definitions, thermal recovery times, wattage vs. temperature stability, and application-specific recommendations for PCB rework, fine-pitch SMD, and high-reliability aerospace work.
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.
