roons are a kit for building mechanical computers — think “real-life Minecraft redstone“. (Comparison only; we’re not affiliated with Minecraft.)

Our kits are available for purchase on whommart. We also have a range of open-source designs you can 3D-print yourself (currently released as early access to our Kickstarter backers).

powerful

Snap together logic gates, state, and other miniature components to invent your own devices — transistors, memory, processors, programs, and much more. The only limit is our funding your imagination!

modular

Combine drives for an endlessly extendable workspace.

portable

compact design lets you take it anywhere — stick it in a bag or even a (big-ish) pocket.

Stack up your kits for tidy storage:

extendable

Add extra functionality with modules. For example, use a buffer to store up to 8 bytes, supply inputs, or present a circuit’s results.

Or use the axle adapter to connect up your own mechanisms:

We have several other peripherals under development, including:

  • An alphanumeric display, allowing circuits to output text
  • A keyboard, making it easier to input data
  • A bridge for connecting a physical device to the simulator, allowing for data to be transferred between the physical and virtual worlds

And if you want something not on that list: we’ll shortly be open-sourcing the underlying protocol, GRIB, allowing you to design your own extensions to roons. (An early-access version is currently available to our Kickstarter backers.)

educational

Our free interactive tutorials walk you through the fundamentals of computing. Learn what bits really are, and how to control them — then work up to building full-on computer components.

You don’t need to know anything about computers to get started, but by the end you’ll know at least some things. Impress your friends and afear your enemies with your newfound mastery of computing.
