Why I Built a Browser-Based Circuit Editor (SchemaLite)

🧠 Why?

As an electronics engineer working in the automotive industry, and someone who also teaches embedded systems at university, I’ve been dealing with circuit diagrams for years.

But there’s one problem that kept coming back again and again:

There was no simple way to quickly create clean circuit diagrams for presentations or documentation.

⚡ The problem

Since my early days during my electronics degree (around 10 years ago), I’ve used many tools:

• Professional EDA tools (KiCad, etc.)
• Simulation software
• General diagram tools

And they all share the same issue:

• Too complex for quick diagrams
• Not focused on visual clarity
• Or designed mainly for simulation, not presentation

Sometimes, I just wanted to quickly sketch a circuit that:

• looks clean
• is easy to understand
• and is ready to drop into slides or docs

But that workflow didn’t really exist.

💡 The idea

So I decided to build something focused on one single goal:

A fast, simple way to create good-looking circuit diagrams.

• No simulations
• No heavy setup
• No unnecessary complexity

Just drawing schematics — fast.

🚀 Introducing SchemaLite

👉 https://schemalite.com/

SchemaLite is a browser-based circuit diagram editor designed specifically for speed and simplicity.

✨ Core principles

• Fast to use
• Minimal learning curve
• Clean visual output
• Focused only on schematics

🛠️ What it currently does

• Drag & drop components
• Grid-aligned layout
• Wire connections between components
• Clean and simple interface

🤔 Why not existing tools?

Tools like KiCad are powerful — but:

• They’re not optimized for quick diagrams
• They come with a lot of overhead
• And they’re often overkill for simple use cases

SchemaLite tries to fill that gap.

🧪 Still early — feedback welcome

This is still an early version, and I’m actively improving it.

If you:

• work with electronics
• teach embedded systems
• or just need quick schematics

I’d love to hear your feedback.

🙌 Final thoughts

This started as a personal frustration, but I suspect others might have the same problem.

If that’s the case, I’d love to build something genuinely useful here.
