A Keyboard for Every Being In the Universe
Measure your hand and use it to design the perfect keyboard
A great ergonomic keyboard should fit your hand shape, but it's difficult iterating through prints and testing. Cosmos lets you measure your hand and place it in the editor, allowing you to put yourself in the design process.
Intuitive Controls, Everywhere
Play with sliders or code, your choice
If you've configured a Dactyl keyboard before, the Cosmos generator gives you a familiar set of options to adjust. But the true power of the editor lies in Expert mode, where you can adjust the position and rotation of every key. Alternatively, take over and code using TypeScript to programmatically generate the key layout.
The Galaxy is the Limit
Design anything, as long as it's a keyboard
The generator isn't limited to keyboards that fit a single adult human hand. Design keyboards for babies. Design keyboards for cats. Design keyboards that fit two hands... like a normal keyboard. Dream it and with some practice in Expert mode, you can design keyboards like the ones on the left in under 5 minutes.
Compatible With Your 3D Printer And Your CAD Software
Generate high-quality STLs for printing or STEP files for further editing
Cosmos uses the OpenCascade geometry kernel, the same kernel that powers FreeCAD and CadQuery. It can export STEP files, making it easy to use Cosmos as a starting point and build your next keyboard in your favorite CAD software.
FAQ
When is the generator being released?
By the end of this year (but hopefully sooner).
If you don't mind buggy software, join the Discord and try the beta!
Is the project Open Source?
Cosmos uses an open-core model. Everything you need to scan your hand to build and program a keyboard is or is going to be open source. Meanwhile some cosmetic features (such as rounded sides) are not open-source and available for a small fee so that I can recoup some of the costs buying keyboard parts.
So far the hand-scanning process is open source. I'll be open-sourcing more as the codebase stabilizes.
Can I use the generator today?
If you're migrating from my Dactyl generator, you'll find Cosmos already produces more robust models, and I recommend you switch, as long as you're ok with a few breaking changes.
New features like trackball support and OLED displays have been released, but I recommend waiting for Cosmos to mature before using these unless you like hot glue.
