We build production-grade BLE devices on nRF — not prototypes.
Custom multilayer PCB — actual size. Designed to fit inside a golf ball core and verified for mass production.
The ProblemA BLE device that fits inside a golf ball — and lasts a year
The challenge was fitting a BLE device inside a golf ball while achieving 9–12 months of battery life. A previous attempt using ESP32 had already failed.
What We Actually Did- Designed custom nRF firmware with motion-triggered wake
- Achieved 9–12 month coin cell life using nRF efficient sleep cycles
- Replaced MPU6050 with a 3-axis gyro for accurate rotation tracking
- Designed a multilayer PCB verified via PCBWAY
- Built BLE mesh across the golf course
Custom PCB shown next to a wristwatch for scale — designed for real athletes, not lab benches.
The ProblemSprint & long jump tracking on a coin cell — that lasts the full session
The challenge was accurate athletic event detection — sprint starts, jump takeoffs, landings — from a wearable that fits on the wrist and survives a full training session on a coin cell. Continuous sensing drains most devices before halftime.
What We Actually Did- Event-driven firmware — MCU sleeps until IMU interrupt fires, no polling loops
- Context-aware sleep: deep low-power state when athlete is resting, instant wake on motion
- Threshold-tuned IMU filtering to eliminate false triggers from vibration and handling
- BLE transmission in tight, batched windows to minimise radio-on time
- Compact PCB with RF keep-out zones for stable BLE performance on-body
