About MakersDeck
Your All-in-One Electronics Engineering Toolkit — free, fast, and built for makers everywhere.
🛠 What is MakersDeck?
MakersDeck is a free, browser-based electronics engineering toolkit built for the global maker community. Whether you are a hobbyist building your first Arduino project, a university student studying digital logic, or a professional engineer designing a power supply — MakersDeck gives you the tools you need, instantly, without installing anything.
From interactive MCU pinout diagrams and IC lookup tables to logic gate simulators, op-amp calculators, and PLC ladder logic tools, MakersDeck brings together the resources that electronics practitioners reach for every day — all in one place.
Everything runs directly in your browser. No sign-up. No subscription. No data uploaded to our servers. Just open the page and start building.

Makers Blog
In-depth guides on topics like motor selection, I2C sensors, PWM, MOSFET drivers, and microcontroller tutorials.
💡 Why We Built MakersDeck
Every electronics project involves the same frustrations: hunting across ten different browser tabs for a pinout diagram, re-deriving the same resistor formula, switching between separate tools for different tasks. MakersDeck was built to solve exactly that problem.
We believe that the best engineering tools should be fast, free, and friction-free. There should be no barrier between an engineer and the information they need. No account creation, no paywalls, no software to install and update.
The entire MakersDeck toolkit runs client-side. When you enter values into a calculator, build a logic circuit, or process an image, that data never leaves your device. This is a deliberate design choice — your work is yours.
✅ Our Values
- ✓Free forever — core tools will always be free to use, no credit card required.
- ✓Privacy first — calculators and simulators process data locally. Nothing you design or calculate is sent to our servers.
- ✓Accuracy matters — every calculator and formula is verified. If you spot an error, please tell us.
- ✓Built for all skill levels — from a teenager building their first LED circuit to an engineer designing a switching power supply.
- ✓Continuously improving — we add new tools and fix bugs regularly based on community feedback.
