Re: [neonixie-l] Re: Homebrew high voltage nixie power supply

I suggest to try tying the enable to ground so as to ensure that there is no interference or unknown phenomenon along the enable which would cause the HV to stop. The HV will have to be connected to system ground to complete the circuit. My thought is that by connecting the ground on the output

Re: [neonixie-l] Re: Homebrew high voltage nixie power supply

If you have a digital scope, here are a few things to try: 1. In your controller, add a few lines of code to wiggle a spare I/O pin when the controller gets reset. Then use this to trigger your scope; if noise is causing your controller to restart, your scope will catch it. I've done this, and

That sounds promising, I note that in your suggested diagram you have also connected the HV enable to the same ground - was that in order to first resolve the glitches before moving on to using the HV control (which has worked fine thus far)? I can connect the HV output ground to the Smart Socket

Re: [neonixie-l] Re: Homebrew high voltage nixie power supply

Tremendous respect Michael. I am currently redesigning a boost converter using a LM3478. It’s a surprisingly involved process, especially if not well acquainted with power circuitry. I’ve found that, between refinement of component values and board layout design, it’s very much an art and science.
