left part with a cut


PCB left 201604212151


  1. Slim low-profile design
  2. Split into 2 halfs for outstanding ergonomy
  3. Portable - easily foldable
  4. USB connection - use it anywhere
  5. Modern look - please your heart
  6. Open Source - never be dependent




  • contact P. Jakoubek, D. Kolibáč, and L. Hejkal regarding the plastic parts of scissor switches (injection moulding into a steel/aluminium mold?)
  • choose a better fitting HW license (similar to MIT and CC BY-SA 4.0, but with a notion about HW patents in a way, that anyone using this or derived work can't be sued)
  • investigate double-trackpoint/point_stick placement - (un)mountable?, each half it's own and fixed?, 90°-rotated thumb micro-switches on the side?
  • marketing (Student Agency - no place for keyboard; ...)
  • add numeric keyboard to be successful on market
