Step 4: Completion
I hope this is helpful and if you have any question let me know.
*note: 6P was tested with an oscilloscope, 1, 5, are calculations only, 7-10 are rough calculations. RPM accuracy is based on you doing your own math and the accuracy of your resistor/s
you might want to use a variable resistor to fine tune.
1/4 watt sould be fine, but use 1/2 watt resistors if you want.
Let me know what you think.
