Hello again!

I have gone through the assembly process a second time. I have a new shiny unit– I am getting a solid 380V but the duty seems unusually low around 18% (at the default 13khz inverter configuration). Should the goal be to have around 50% duty for correct operation, or is anything less acceptable?

However there is now a new problem, the microchip appears to be running very slow. The device is slow to boot, and the screen is slow to change, it takes several seconds to update the timer for example. I have tried another microchip and it has the same issue. I am wondering if the 8mhz crystal is bad or one of the capacitors in that crystal circuit.

I will continue tinkering.
