✅ Phase 2 Achievements

1. Power Budget Calculator

File: /app/power/page.tsx

Features: - ⚡ Dynamic component management (add/remove/edit) - 🔋 Battery capacity calculation - 📊 Peak vs average current analysis - ⚠️ Safety warnings (high current, wire gauge, etc.) - 💰 Battery recommendations with Thai pricing - 🔌 Cell configuration suggestions (1S-5S) - 📈 C-rating calculations

Calculations: 

Total Average Current = Σ(Component Current × Quantity) / Efficiency
Total Peak Current = Σ(Peak Current × Quantity) / Efficiency
Battery Capacity = Average Current × Runtime × Safety Margin

Example Output: - 2× Motors (12V, 0.3A avg, 2.5A peak) - 1× ESP32 (5V, 0.15A avg, 0.25A peak) - 1× Sensors (5V, 0.1A avg, 0.15A peak) - Result: 3000mAh 3S LiPo, 30C rating, ฿600-1200

2. Kinematics Calculator

File: /app/kinematics/page.tsx

Features: - 🎯 Differential drive calculations - 🎮 Interactive sliders for velocity control - 📊 Real-time wheel speed display (m/s and RPM) - 🔄 Turning radius calculation - 🎨 Visual movement representation (SVG) - 📝 Detailed explanation output

Formulas: 

Left Wheel Speed = Linear Velocity - (Angular Velocity × Wheel Base / 2)
Right Wheel Speed = Linear Velocity + (Angular Velocity × Wheel Base / 2)
RPM = (Velocity / Wheel Radius) × 60 / (2π)
Turning Radius = Linear Velocity / Angular Velocity

Preset Movements: - ↑ Forward (v=0.5, ω=0) - ↻ Turn Left (v=0, ω=1) - ↺ Turn Right (v=0, ω=-1)

3. Motor Database

File: /data/motors.ts

Motors Included: 1. N20 Micro Motor (6V/12V) - ฿50-100 2. TT Motor (6V/12V) - ฿40-90 3. GA12-N20 Geared Motor - ฿80-120 4. JGA25-370 Medium Torque - ฿150-250 5. JGB37-520 High Torque - ฿250-400 6. SG90 Micro Servo - ฿30-50 7. MG996R Metal Gear Servo - ฿150-250 8. NEMA 17 Stepper - ฿200-350

Features: - Detailed specs (torque, RPM, current, weight) - Thai pricing - Availability status - Usage notes - Search/filter functions
