A Unique Perspective on Feature Creeping

The podcast got mentioned in an article! 12 Great Podcasts for Engineers from the Mind Tribe blog. Mind Tribe is a design driven engineering firm based in San Francisco. The list spawns from a survey from the engineering team at Mind Tribe. Thanks Mind Tribe for mentioning our podcast!

“This is a technical podcast by a Texas-based PCB fab and assembly house where the two hosts (Parker and Stephen) have conversations about electrical engineering. Parker and Stephen provide a unique perspective on hardware and the show is both entertaining and educational.”

Stephen
- “Feature creeped” my way into designing a 20 band graphic eq and a fancy solid state effects loop
  - 20 band eq with +/- 12ish (simulation shows 13.8) db of gain per band
  - Each band has a Q of 2.87 so they end up being ½ octave
  - Using the 1kHz standard
  - Designed with “constant Q” in mind
  - W taper pots and ways to convert that
  - Both the FX loop and the EQ interface with 200v input signals
  - Applied a 1:50 reduction to get within a reasonable range.
