02 / Flagship Project

AARIGAA

Weather network

A distributed environmental sensor network engineered from the ground up. Every enclosure, every PCB, every firmware revision built by LED. Real-time data, purpose-built hardware, feeding a live aggregation platform at aarigaa.net.

AARIGAA is the benchmark for what we build.

03 / STEM Outreach

Open Source Projectsfor curious builders

Every project includes a video walkthrough, printable 3D files, a full bill of materials, and step-by-step build instructions. No paywalls, no kits required.

Lamella HowtoIN PRODUCTIONBeginner

Lamella Howto

Your first walkthrough with Lamella — design and read a real-world circuit from the ground up. The foundational primer that opens the door to every build in this library.

Tools & referenceswe actually use

No affiliate links, no sponsored placements. These are the software, suppliers, books, and communities that show up in our actual engineering workflow — listed because they're genuinely useful.

19 resources shown

SOFTWARE

Altium Designer

Professional EDA suite for high-density, multi-layer PCB design — the industry-standard toolchain, and our go-to for every board we build.

SOFTWARE

Lamella

Browser-based PCB layout and netlist companion, built by Lotus. Import a SPICE netlist, place parts on a net-aware through-hole grid where every connection carries its net's color, run DRC, and export a PDF build sheet. A teaching-first tool for going from circuit to buildable board — no install, no account.

SOFTWARE

STM32CubeIDE

STMicroelectronics' IDE for STM32 microcontrollers — integrated code generation, peripheral config, and debugging.

BOOK

The Art of Electronics

Horowitz & Hill. The canonical reference for analog and digital circuit design. Read it cover to cover.

TUTORIAL

Adafruit Learning System

High-quality tutorials on sensors, microcontrollers, and embedded systems. Great for all skill levels.

SOFTWARE

PlatformIO

Well-regarded embedded dev environment across Arduino, ESP-IDF, and more — worth knowing if you're building firmware.

SUPPLIER

DigiKey

Large catalog with excellent datasheets. Our go-to for rapid prototyping sourcing.

COMMUNITY

Hackaday

Project showcase and hardware news — worth a browse for inspiration, even if it's not a daily stop.

COMMUNITY

EEVblog Forum

Serious electronics engineering discussion. Dave Jones' community for professionals and hobbyists alike.

PLATFORM

Printables

Prusa's 3D model sharing platform. Where we publish LED project STL files for download.

BOOK

Practical Electronics for Inventors

The bench book. Scherz and Monk cover the whole practical span — components, circuits, and the how-to of actually building — so it's the one we reach for mid-build, not the theory tome that stays on the shelf.

BOOK

Bogatin's Practical Guide to Prototype Breadboard and PCB Design

Eric Bogatin's foundation for boards that work on the first spin — connectivity first, then the signal-integrity and noise principles that matter for precision analog. Built around a risk-management process that keeps re-spins rare.

SOFTWARE

Fusion 360

Autodesk Fusion — parametric CAD/CAM in one place for enclosure and mechanical design, with cloud collaboration and a direct path from model to fabrication.

SOFTWARE

EasyEDA

Free and browser-based, easy to start, and it scales into real multi-layer work as you grow — a friendly on-ramp to PCB design.

PLATFORM

Ultra Librarian

Ready-made schematic symbols, PCB footprints, and 3D models for most EDA tools — pull a part's library data instead of drawing footprints from scratch.

COMMUNITY

RF Cafe

Long-running RF and electronics reference hub — calculators, formulas, and engineering reference worth keeping bookmarked.

PLATFORM

GrabCAD

Massive free library of community CAD models, plus a maker community — handy for reference geometry and off-the-shelf part models.

SOFTWARE

LTspice

Free SPICE simulator from Analog Devices — schematic capture, analog/switching circuit simulation, and a built-in waveform viewer.

SOFTWARE

LTpowerCAD

Free power-supply design tool from Analog Devices — guides switching-regulator design end to end, with part recommendations, efficiency and loop estimates, and an export path to LTspice.
