Brainstorming ideas, oscilloscope plugin was decided a winner.

Developed a timeline, scope, identified concerns. Outlined action items:

Research: prior art, has it been done before, can we use multimeter tech

Design: current limiting, voltage reduction, circuit protection/fuses, mechanical design

Development: Breadboard then Veroboard then PCB

Requirements: to investigate

Concerns: can we make it possible for DC? Has it been done before?
