Very interesting project. I think your project is related to electric field, but more likely communication mode such as BPSK, BFSK, etc. If you give me a chance of discussion, I can complete your project in 2~3 days. Sure. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Hi I can help you with the hardware design for an Texas Instruments instaspin implementation. I can also guide you through the software setup for FOC control of brushless DC motors and AC induction motors. I already have custom schematic and pcb design for instaspin. It could be adapted to your voltage and current requirements. What is your application? Voltage input? If it is not for motor control, the hardware design may be more involved and require more hours.
