Small side project that got a bit out of hand: a 3D sandbox in the browser where you can build an electronics project, program it and let it run in a simulated world – rain, heat, wind, water, days in time-lapse.

Small stuff like a reaction game works, and bigger stuff like a garden irrigation with 3 Arduinos. There's a thermal view to see what gets too hot and a test bench that shows where your build would fail.

It's an early prototype. Mostly want to know if this is useful to anyone or just a fun toy

(weird domain, it's a test server)

Edit: works best on a laptop/desktop – on phones it runs, but it's pretty cramped.
