ExoSynk
Public beta · 2D + 3D lab, community, store — all live

The virtual lab where electronics come to life.

Design circuits in 2D, model enclosures in 3D, write Arduino code, publish tutorials, sell models, earn coins — all in one place, all in your browser.

Inside the lab

A workbench that actually simulates

Real physics, real Arduino, real instruments — same as the one on your desk, minus the burnt fingers.

Schematic editor

Drag parts, snap to grid, route wires with junction dots and hops. Full keyboard shortcuts. Comments, upvotes, forks on every lab.

Honest DC + transient sim

Modified Nodal Analysis under the hood. LEDs glow at their correct current, capacitors follow real RC curves, parts can burn out.

Multimeter & oscilloscope

Probe any node for voltage or current. Two-channel scope with adjustable timebase. Voltage-gradient overlay paints the whole circuit.

Arduino + Monaco editor

Virtual Arduino Uno with digital and analog pins. digitalWrite, analogRead, PWM, serial — your sketch drives the circuit in real time.

3D lab + modeler

Model enclosures and holders in 3D. Duplicate, shell, grid-snap, measure, bend, OBJ/STL export — ready for the printer.

Cloud save & GitHub-style URLs

Local-first sync. Clean URLs: exosynk.com/handle/project. Make a lab public and anyone can view, run, and fork it.

One platform

The whole hardware loop in one browser tab

Design it, publish it, teach it, sell it. ExoSynk is every stage of the build.

Lab

2D circuit editor with DC + transient simulation. 18 parts, Arduino Uno, multimeter, oscilloscope, voltage-gradient overlay.

3D Lab

Design enclosures and mounts. Duplicate, shell, measure, bend, grid-snap. Export to OBJ or STL for printing.

Store

3D-printable models from the community. Free to download. Upload your own, set a price, earn coins on every download.

Learn

Tutorials and research write-ups linked to runnable labs. Free and paid. Creators keep most of what they earn.

Signal

Short posts, builds, memes. Follow graph, @mentions, threaded replies, likes — all attached to labs when you want.

Wallet

Coins power paid listings, subscriptions, and ads. Creators earn; buyers spend; admins manage. Ledger is fully auditable.

Workflow

From idea to running circuit in 30 seconds

1

Drag parts

Battery, resistor, LED, Arduino — click, place, done.

2

Route wires

Click pin → click pin. Wire tool handles hops and junctions.

3

Run & share

Auto-simulates on change. Probe with multimeter or scope. Share the link, publish to Store or Learn.

Built in public

Fork anyone's lab.
Remix it. Ship your own.

Every public lab is a starting point. Browse Explore, open the schematic, fork — the code, wiring, and parts come with it. Upvote, comment, follow the builders you love, DM them when you want to collab.
