charje has created the Power User Keyboard, a unique custom keyboard with a non-conventional bottom row of keys. The result of the extensive documentation of the project is effectively a general-purpose guide for the creation of Teensy-based custom keyboards.

With full detail of parts, cost, and tools to create the layout, case, and firmware (automatically generated by QMK), charje’s project write-up provides a complete end-to-end roadmap. We’d love to see a 7-row ThinkPad-style keyboard implemented along similar lines! Check out the project’s sourcehut page for more details.
