README
README.mddynamics lab
Dynamics experiment to investigate resonance of a mass-beam system. Free decay or driven oscillations can be measured. Frequency of driven oscillation can be controlled using a stepper motor and the uStepper s32 driver board.
Initial prototype designed as part of an undergraduate student project in the School of Engineering, University of Edinburgh. That design was modified and implemented in this remote laboratory for the Structural Mechanics and Dynamics 3 course in the same department. The experiments are on public display in the School of Engineering:

Questions
How big is the Dynamics accservo shield PCB?
It measures 41.5 × 39.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dynamics accservo shield use?
17 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Dynamics accservo shield KiCad files?
From the practable/dynamics-lab repository on GitHub, at the commit this page was made from: the board is hw/shield-pcb/dynamics-accservo-shield/dynamics-accservo-shield.kicad_pcb and its schematic hw/shield-pcb/dynamics-accservo-shield/dynamics-accservo-shield.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dynamics accservo shield design in my own project?
Its repository publishes it under the AGPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
