236: The Concept of Delayed Gratification (Repeat)

Embedded.fm · 20 Aug 2020 · 1h 10m · Episode 236

What this episode covers

Roger Linn, founder of Roger Linn Design, discusses the engineering behind the LinnStrument, an expressive electronic instrument featuring 200 3D-sensing pads that measure pressure, pitch, and timbre. He explains how he uses force-sensing resistors (FSRs) printed on Mylar sheets and a key matrix scanning technique to achieve low-latency, polyphonic control, while managing the N-key rollover limitation through software. Linn also details his business model as a solo founder, his use of Raspberry Pi Compute Modules for cost-effective embedded systems, and his advice for hardware entrepreneurs to prototype using existing low-cost components rather than commissioning expensive custom builds.
