Continuity Tester

I want to build a continuity tester that's fast, tiny, and can attach to a board I'm reversing so I don't need full multimeter when reversing boards away from a desk. The hardware files for this can be found on GitHub at sarahemm/continuity_tester.

Status

  • 2018-01-11: Received PCBs and parts, started assembling.
  • 2017-12-13: Completed PCB design, sent to OSH Park for manufacturing.
  • 2017-12-11: Started putting idea together after spending lots of hours reversing for the DMS project. BOM and schematic done, PCB layout in progress.

Features

  • Fast, latching to catch quick pulses as probe is dragged along multiple pins.
  • Visual/audio switchable options
  • Lasts a long time on a CR2032 or similar
  • Clips or magnets to a board I'm working on to save having another thing to put somewhere.

Rev001 Issues

  • Holes for jacks are way too small
  • Footprint for trimmers fits, but is way way oversized
