Just gotta flag up this project: #Hacking any linear slide/bearing into piezo motor posted by @Edwin Hwu.

"Herein we present the design of an open-source XYZ-axis nanopositioning system. Utilizing a magnet-based stick–slip driving mechanism, the proposed XYZ nanopositioner provides several advantages, including sub-nanometer resolution, a payload capacity of up to 12 kg (horizontal), compact size, low cost, and easy assembly; furthermore, the system is adjustment-free.

The project links to a journal article. The journal looks a bit like HaD with editorial standards and peer review. And it's open access. The existence of open access journals is something of a successful hack itself, but I am at risk of digressing further...
