From the project

Objective: Finish a project that has dragged on for 14 months.

Objective: Finish a project that has dragged on for 14 months.

Deadline: April 31, 2026 for creepless imaging of graphite

$80,000 worth of wire transfers have hit the bank. I now have enough financial security to proceed with hardware work.

The first step is ensuring I can be paid a full-time salary. Comply with US tax laws, SEC regulations, etc. I predicted the exact numbers before going through the legal boilerplate and setup.
