Mini4WDLaptimerV2 byNSDev vs モーター回転数計

**App Overview** This app uses your smartphone's camera to measure lap times for Mini 4WD cars, RC cars, Kyosho Mini-Z, and similar vehicles. It offers detailed settings to ensure accurate measurements. By entering the course length, speed can also be displayed. **Main Features** **- Font Size**: Adjust the font size for lap times and statistics. Choose the optimal size for visibility and layout. **- Decimal Places**: Specify up to 9 decimal places for speed and time values. Choose between high precision or simplified display. **- Screen Rotation**: Configure the display for easy viewing in both portrait and landscape orientations. **- Sound Effects**: Enable sounds for lap detection and start events. Useful for notifications or silent operation depending on your needs. **- Light**: Turns on the LED light during camera use to improve detection accuracy in dark environments. **- Detection, Measurement, and Camera Settings**: Fine-tune camera FPS, detection sensitivity, focus, and zoom. Customize detection conditions based on your environment and course. **- Detection Point Settings**: Specify which points on the screen trigger lap detection. Choose freely from 81 selectable detection points. **- Course Length Settings**: Automatically calculate accurate lap distances based on course type (2-lane/3-lane) and selected parts. Used to compute lap speed. **- Manual Measurement**: You can measure manually when the camera is unavailable or permission is not granted. **How to Use** 1. Place your smartphone on the course (ensure it is stable and vibration-free). 2. Tap Start. 3. When the car passes, measurement begins. 4. Tap Stop after the desired number of laps. 5. Review lap and split times. 6. Share lap time data from the menu. **Q&A** **Q. Menu operations are slow to respond. ** A. When the camera is active, overall responsiveness may decrease. You can tap the camera image to stop the camera. Tap it again to restart the camera. **Q. The Mini 4WD doesn't trigger detection when passing.** A. If detection fails, try lowering the sensitivity value to improve responsiveness. The default is 100, but around 80 may work better. Detection may be difficult if the car and course colors are similar. **Q. Speed is not displayed.** A. Speed information will not appear unless the course length is set. Please enter the course length from the menu. **Q. I set the course length, but where is the speed shown?** A. Scroll the lap list to the left to reveal the speed on the right side. **Q. Can I set a lap count for automatic stop?** A. Yes. You can specify the auto-stop lap count from the settings menu. The default is infinite. **Q. Does lap time accuracy vary by device?** A. Yes. Accuracy depends on your device's camera frame rate. **Q. Can I mute the sound?** A. Yes. You can disable sound from the options menu. **Caution** Lap time accuracy depends on your smartphone's camera performance. At 240 FPS, there may be an error of 0.0042 seconds. Higher FPS may cause the device to heat up. Be cautious of thermal shutdown. Continuous use of the light may also cause overheating. Due to device protection, the light may stop functioning when hot. Please wait until the device cools down. **Disclaimer** The developer shall not be held responsible for any damages or issues resulting from the use of this app. Please use it at your own discretion. **Other** [ミニ四駆] is a registered trademark of Tamiya, Inc.

モーターに近づけるだけ。無負荷回転数がその場でわかる。 模型用の小型ブラシモーター（130・540サイズ）の駆動音を iPhone のマイクで拾い、その周波数から無負荷回転数（rpm）を算出する音響式の回転数計です。専用の回転計を用意しなくても、慣らし（ブレークイン）や選別のたびに回転数を確かめ、記録して比べられます。 ■ 数字が「止まる」 解析した回転数が安定すると、数字がロックして動かなくなります。揺れ続ける数値を目で追う必要はありません。ロックした値の最大（MAX）は針で残るので、一番回る個体がひと目でわかります。 ■ 測って、記録して、比べる モーターごとに測定を記録（回転数・電圧・電源・メモ）。同じロットの個体同士や、慣らし前後を並べて比較できます。 ■ 使い方 1. ピニオンを外し、モーターを無負荷で回す 2. iPhone のマイク（本体下部）をエンドベル側に 5〜10cm ほど近づける 3. 数字がロックしたら「保存」 ■ 無料でできること ・リアルタイムの回転数（rpm）と周波数（Hz）、ロック、MAX ・スロット係数（3 / 5 / カスタム）と、手持ちの回転計の値で合わせる較正 ・モーター台帳 3本まで、その範囲での比較、結果の共有画像 ■ Pro（買い切り） ・台帳 4本目以降（無制限） ・電圧補正（3.0V 換算）での比較 ・慣らしの推移グラフと伸び率 ・CSV 書き出し ・ギア比・タイヤ径からの理論最高速（無負荷・目安） ■ ご注意 ・無負荷時の測定専用です。走行中・負荷時の回転数は測れません。 ・周囲の騒音や複数のモーターの同時運転は測定に影響します。1本ずつ、静かな場所でお使いください。 ・音響方式のため数値は目安です。慣らし前後や個体間の相対比較にお使いください。 ・音声は端末内で処理し、保存・送信は一切しません。 本アプリはミニ四駆をはじめとする模型用モーターの計測を想定して作られていますが、株式会社タミヤとは一切関係ありません。
