in Extremely useful system #0 hanger. Stepper motors are driven by micro-controller with a wood stick and bended hanger wire embedded on the axis of the stepper motors. A glove is one the top of hanger to imitate the motion of “the Sign of the horns”in band show , but a mechanical one.

非常に有用なシステム #0 – ハンガーでは、ステッピングモーターの軸に木製棒と曲げたハンガーワイヤーを埋め込み、マイクロコントローラーで駆動する。ハンガー上部に手袋を装着し、バンドショーにおける「角のサイン」の動きを模倣するが、これは機械的な動作である。
