What exactly does it measure?
Peak launcher-shaft RPM from an analog optical sensor, plus gravity-relative tilt from the M5’s IMU. Its RPM has been compared with a laser tachometer reading the spinning Beyblade; that is a comparison, not a calibration of the launcher-shaft measurement, so use readings to compare your own pulls. It does not measure Beyblade release RPM, blade spin, force, torque, travel distance or heading. Launches below 1,000 RPM are ignored.
Which launchers fit?
The print-in-place clamps attach removably to Beyblade X string launchers. Check that they hold firmly, the sensor has a clear view and nothing rubs on your launcher. I have only tested it on one launcher so far.
What is checked physically?
The assembled LaunchLab is built and working, but which mount assembled units ship with isn’t decided yet. Current Top Mount v19, Sidecar v7 and TCRT v102 files have passed CAD and slicing checks; their revised fit and retention still need a physical test. Test-fit your prints on your own launcher. Images on this page are CAD renders.
