The hardware isn't changing, why not get AI to build custom drivers?
AI generates zero-overhead audio paths by skipping generalized abstractions for your exact hardware.

AI Analysis
●●SolidBig BrainNiche GemSolve My Problem
Switching regulator + deep sleep firmware profiling gets 6 months from 1800mAh e-ink.
Strengths
- •Detailed real-world power profiling methodology using Nordic Semi kit, not hand-waved estimates
- •Component tradeoff analysis (ESP32-C3 vs alternatives, linear vs switching regulators) shows genuine engineering rigor
- •Device/server work-split architecture lets servers do rendering while hardware sleeps, novel for e-ink IoT
Weaknesses
- •Blog post format doesn't provide reusable firmware code or hardware schematics for reproduction
- •Narrow audience: only relevant to people building battery-powered WiFi IoT hardware
