Hi Product Hunt 👋 I’m the founder of PI SpeedLAB. We started building PI-Link because we were frustrated with traditional speed guns — limited processing power, inconsistent readings, and expensive hardware. So we asked: What if we used the smartphone’s CPU instead? By combining Doppler radar hardware with smartphone-level computing power, we built a smarter way to measure baseball velocity. We’d love your feedback — especially from athletes, coaches, and hardware builders. Ask me anything!



PI-Link Speed Radar
Hi Product Hunt 👋
I’m the founder of PI SpeedLAB.
This project actually started out of frustration.
Every time we compared readings from traditional speed radars, we noticed inconsistencies. The hardware was expensive, but the processing power inside was surprisingly limited.
That made us wonder —
why are we still relying on tiny embedded processors when everyone already carries a supercomputer in their pocket?
So instead of trying to build a smarter speed radar…
we decided to build a smarter system.
PI-Link uses Doppler radar hardware, but lets the smartphone handle the heavy signal processing. That shift changed everything for us.
This is still a journey. We’re refining accuracy, improving filtering, and constantly testing against legacy devices.
If you’ve built hardware, worked on signal processing, or care about sports tech — I’d genuinely love your feedback.
What would you improve?
What would you question first?
