Product design and manufacturing notes from CADLETE Designs: DFM, embedded electronics, prototyping, and getting hardware to production.https://cadletedesigns.com/enhttps://cadletedesigns.com/blog/electronics-integrated-hardware-lessons/https://cadletedesigns.com/blog/electronics-integrated-hardware-lessons/Across a wireless pickleball scorer, a timer-locked phone pouch, and a reverse-engineered water flosser, the same pattern keeps showing up: the electronics decide the mechanical design, not the other way around.Thu, 20 Aug 2026 00:00:00 GMTPCB & Electronics DesignCADLETE Teamhttps://cadletedesigns.com/blog/reverse-engineering-water-flosser/https://cadletedesigns.com/blog/reverse-engineering-water-flosser/A client wanted a next-generation water flosser with two features no standard flosser had.
