This project is to study the design and construction of nano fibers from lac blender, rotary jet spinning, creating a high voltage direct current. TL494 in control signals pal ล์ต straight leg 3 and adjust the Duty Cycle from the variable resistor (VR1) 0 - 80 percent and frequency can be obtained 5 high - 100 kilohertz. By the VR2 C1 (,) from the legs and leg and 5 6 when the pulse signals to drive through the gate drive circuit by the circuit to create a direct current high voltage. By creating the benefit can be applied in various fields such as medicine, cosmetic, and in industrial, etc., for this project is to study the application of nanomaterial. Such as nano fiber in medicine. The project will use the polymer obtained according to such as the northern shellac. Used as a precursor in the production of fiber. Nano fiber by means of spinning machine with electronic electro spinning. To create a fiber manufacturing machine nano fiber (prototype) for applications in nanotechnology
