Rev your engines because this isn't just a race. It's a test of how well you think on your feet, solder under pressure, or explore a new field in engineering.
Circuit Metanoia challenges engineering teams to design and build a remote-controlled toy car from identical components, then run it through 5 laps of a 25-meter loop as fast as mechanically possible.

✔️ Receiver: ESP32-C3 remote control (4 buttons)
✔️ Transmitter: ESP32-C3, battery system, motor driver, motors, and wheels
✔️ Chassis material: Popsicle sticks, 4 meters of stranded wire, soldering lead, and soldering flux
𝙍𝙖𝙘𝙚 𝙋𝙖𝙧𝙖𝙢𝙚𝙩𝙚𝙧𝙨
✔️ Track: 15 meters per lap × 5 laps
✔️ Start format: Standing start
✔️ Cars must stay within track boundaries at all times
𝗣𝗥𝗢𝗚𝗥𝗔𝗠𝗠𝗜𝗡𝗚 𝗥𝗨𝗟𝗘𝗦
✅ Acceleration/ramping
✅ Braking behavior
✅ Input mapping
✅ Safety limits (soft start, current limiting, etc.)
❌ Changing BMS voltage limits
❌ Disabling over-current or low-voltage protection
❌ Autonomous driving (no line following, timers, or non-stock sensors)
❌ Any program that removes direct operator control
𝗣𝗢𝗪𝗘𝗥 𝗥𝗨𝗟𝗘𝗦
⚡Battery + BMS must be used exactly as supplied (3.7V → 5V converter)
⚡No battery swapping or charging during active rounds
⚡Battery endurance is not a victory condition
𝗪𝗛𝗔𝗧 𝗖𝗢𝗨𝗡𝗧𝗦 𝗔𝗦 𝗔 𝗕𝗥𝗢𝗞𝗘𝗡 𝗖𝗔𝗥
Your car is considered broken if any of the following happen mid-race:
💥A wheel detaches or goes visibly wobbly
💥The axle shifts out of alignment
💥Motor, battery, or electronics detach or disconnect
💥Structural failure that affects motion or control
