A circuit board for my hot wire cutter to provide a pulsing function, so that different lengths and thicknesses of nichrome wire can be used.
The circuit allows me to control the power supply, constantly turning it off and on varying the current, depending on the type of wire used, as not to melt it.
This is a prototype board to test whether the function will work in conjunction with providing the cutting wire ample heat.
It uses a mosfet with 4.5v gate drive eliminating the need to power the arduino chip separately.
For the final circuit board, I will implement a standalone arduino chip and a potentiometer to control the pulsing function.
