I have a 1uf and .1uf at the 555.
The 330uF was at the PWM driver. Which has since been reduced to 6.7uF.
It is driving 10 parallel mosfet which have a gate capacitance of 53nC typical. Each mosfet has a 4.7 ohm gate resistor. PWM driver is a 14 amp driver so if I calculated it right, I used an order of magnitude greater buffer cap to the PWM driver input (10x). This latest change really reduced the noise of the circuit.
Its getting close but I literally have only 10 minutes here and there to poke at it and my weekend is already booked so still finding time to work on it or even a schematic is limited. I will be producing a schematic though at some point either when I get the circuit right, or find that I am stuck on something.
