Coboll Join the waitlist

In development. Join the waitlist for early access.

You design it. Coboll works out the rest.

Describe the gadget you want and shape it in chat. Coboll generates the circuit, parts list, code and 3D print files. Build it yourself, or we'll build it and ship it to you.

You make the decisions.

Coboll asks the questions a maker friend would, explains the trade-offs in plain words, and redraws the design every time you change your mind.

  • What it does, and when it does it
  • How it looks: shape, colour, size
  • Where it lives and what it has to work around
  • Battery or plug, quiet or loud, simple or clever

One change, redrawn

Version 1
  • Motion sensor
  • Mist when anything moves

You said "my cat goes out there". The parts list, code and enclosure all updated to match.

Everything you need to build it

When the design feels right, Coboll hands you a complete build pack, made for your version.
