2. Sensewheel Mk2 design changes
Wireless: each slave connected to master via Bluetooth
LIPO battery inside slave load cell, rechargeable
Master as tablet or ultimately SmartPhone
6 d.o.f. load measurements at each slave, combined in software to calculate wheel kinetics
More robust

3. MkII
6 dof (Mx, My, Mz, Fx, Fy, Fz)
Bluetooth connection between slave load cells and master
Each slave load cell sends data to the master at a maximum sample rate of 100 Hz
Master designed to be a Windows enabled tablet
