Audio Tach Assistant

How to use:

• Use your preferred guitar tuner or similar app to measure the dominant frequencies of the robot's spinup. Make sure you're doing the spinup in an appropriately safe arena or test box.
• Input the frequency and weapon specifications in this calculator.

The result from this calculator is only an approximation. Frequencies measured may vary depending on weapon design, environmental factors, motors, and other factors. For accurate data, using a laser tachometer or similar is recommended.
