Integrating a Voltmeter with fischertechnik

I took a detour on the road to powered speakers and remixed the cassette lid I previously designed in order to hold a panel mount voltmeter from Adafruit. I set out with a few goals:

  • Blend reasonably well with fischertechnik parts without requiring modifications to those parts.
  • Have two connectors each for positive and ground, so the module can be chained with other modules.
  • Use connectors that work as well as possible with fischertechnik plugs.

Designing a Lid for the fishertechnik Cassette Bottom

I’m working on adding a small powered speaker to a fischertechnik model and decided the simplest first pass would be an insert for the standard cassette that many of the older sets shipped with. I’d like to not alter the original part, so ideally, this will be a simple press-fit part which works very similarly to the stock cover. The first goal was to get a simple flat lid working.
