title: A six-pound battery-powered portable transcranial magnetic stimulator.
abstract: BACKGROUND
  Commercial transcranial magnetic stimulators are massive and may be difficult to transport for lecture and teaching purposes
  
  
  OBJECTIVE
  To design and construct a portable, battery-powered magnetic stimulator of the lowest possible mass for use in demonstrations and simple measurements
  
  
  RESULTS
  The functioning battery-powered single-pulse system is relatively inexpensive, weighs less than 7 pounds, including coil, incorporates external sync capability, and functions well for the intended purposes
  
  
  CONCLUSIONS
  The device may useful for teachers, researchers, and clinicians.
