TMS Overview
• Transcranial Magnetic Stimulation
• Support for deep brain stimulation
● Research for Post Traumatic Stress Disorder, Alzheimer's, Chronic Pain, Parkinson’s, etc.

Problem Statement
• TMS has little support for deep brain stimulation
• No low cost alternative options for research development in TMS
• Current designs lack enhanced control, reliability, and pulse shaping
