Open hardware can own many layers of a machine. The missing layer is a local path to fast active devices that can be fabricated, measured, repaired, improved, and taught.

Article focusThe maker stack reaches boards, firmware, enclosures, fixtures, repair documentation, and tests. It still needs gain, restoration, fanout, speed, yield, and repeatable process control.

The Short Form

The boundary is not open-source design. The boundary is active behavior. A community can publish schematics, HDL, boards, firmware, enclosures, fixtures, and test procedures while still depending on remote silicon for the fast nonlinear devices that make the machine run.

The missing maker fab is the process that moves that active behavior closer to builders.

Original Post

The maker movement can build almost everything around intelligence.
The board.
The enclosure.
The firmware.
The harness.
The test rig.
The repair manual.
The design files.
But not the dense fast active fabric that intelligence runs on.
That is the missing maker fab.
Open hardware will remain partial until makers can fabricate their own fast active devices.
Not merely design them.
Not merely order them.
Not merely package them.
Fabricate them.
That is the next real frontier.
