Build it yourself, build it better

The BallBOPPer™ isn’t a product. It’s a platform. A set of open designs, open code, and open ideas meant for people who like to build things with their own hands — and improve them.

Read the Lab Notes. Download the designs. They are not all available yet, but they are coming.

Use them as‑is or treat them like a starting point. Swap materials, change geometry, redesign entire components.

You don’t need to follow the reference design. In fact, we hope you don’t.

Make a lighter version.
Make a faster version.
Make a kid‑safe version.
Make a version that works on clay and grass courts.
Make a version that uses different sensors.
Make a version that launches balls in a completely new way.
Make a version that provides better tennis training experience than any device that has ever existed.

The BallBOPPer™ is a starting point — not a finished product.

So go ahead. Get to work.
