Key quotes
· 4 pulledWe started building PI-Link because we were frustrated with traditional speed guns — limited processing power, inconsistent readings, and expensive hardware.
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.
