My pendulums
Your boards and your calibration are kept on this device only.
Your pendulums
Calibrate your pendulum
Everyone has their own language with the pendulum. Show it your yes, your no and your “not clear”. The yes-or-no boards will use it.
Test your calibration
Think of a question you know the answer to (“Is my name…?”), say what the right answer is and let your hand move the pendulum.
Run at least three tests to see your score.
Your pendulum's look
Pick the pendulum you'll see when you ask.
