This project is the design and construction of nano fibers spun from the wax model. Rotary jet spinning. Creating a high-voltage direct current with TL494 in control signal pulse on the third leg and Duty Cycle of the variable resistor (VR1) 0 - 80 percent. And frequency can be adjusted 5-100 kilo Hertz designated by (VR2, C1) connected to pin 5 and pin 6 when the pulse is then applied to the drive circuit gate by the user. circuit to generate high DC voltage. The creation The benefits can be applied in various fields such as pharmaceuticals, cosmetics and so on in the industry for this project to study the application of nanomaterials such as nano-fibers in medicine. The project will use a polymer obtained by the North, such as wax used as a precursor in the manufacture of fibers. Nano-Power Rubber way spinning with electrolyte taste Spinning. To create a machine to produce nanofiber fire Harbour (master) for applications in nanotechnology.
