  • Chang the BACK: make the fins (tails) sharper; change the ” curtain” into the smooth surface at the back (behind the tails)
  • still need to change the front ( no “old style surtain” )

  • test Lilypard with servo motor, not working, same coding works on Arduino Duemilanove 328 but not work on the lilypad 328, maybe is caused by the power supply 3.3V only, need extra power supplier
  • conductive sewing thread and the non-conductive fabric (felt) causes extra resistance, which weakens electric current (5.3V changes into 3.8V in s really short distance through the conductive sewing thread and the non-conductive fabric)
  • change to use Arduino Duemilanove 328 to run the servo motors

  • use Wrap wire ( really thin) to replace the conductive thread (reconnect the motors, Accelerometer, HRMI)

  • take off the lilypad and all the soft circuits
  • power supply is really important in this case, after separate all the power, finally the motors work
