| V. DIY ELECTROSPINNER |¶
Electro-spinning machine is designed to produce nano or micro scaled fibers. The syringe with the solution inside is connected by a needle to a high voltage generator and is able to spin or spray the material onto a metal collector. It creates a soft surface on aluminum foil.

CONCLUSION¶
- DIY Machine I. - the servomotor was not powerful enough to control the syringe pressure. Also the horizontal position created air bubbles in the syringe. Depending on the distance between the syringe and the metal plate to create a bridg for spinning was not powderfull enough. The material was attached to the aluminium foil but it was not consistent.
- DIY Machine I. - the vertical position of the syringe caused the drops of solution to hit the metal pad. However it was good for the air compressure to push the solution down through the syringe.
