So bad it's amazing

An inductor would seem logical to limit the inrush to the ioniser but guessing theres probably a good reason why not or you have thought of that so what about using a transistor with a large RC on the base to ramp up the current?

Raven Luni

WOW! Fun indeed sir!

Michael Thompson

Hahah, I love that comment, "delusional design "

Jeff Larson

Found them - they are called Wen Tai component storage boxes. They seem a bit hard to find in stock though (at least in the U.S.). https://www.amazon.com/WenTai-Component-Storage-Boxes-boxes/dp/B00IVPY6J2

Have you a link for the tiny flip-up component holder? Thnx!

Todd Sharp

There is one across the common switched bus.

Don't know if this was already suggested but have you tried a fly-back/catch diode across the ioniser module supply terminals?

Makes me feel a little better - after 'pinging' my resistor across the room for the 3rd time :-)

They were very low intensity, with no sign of a surface for a titanium dioxide panel.

If you're sufficiently rich you could do this. There are jets capable of matching the speed of the earth's rotation, and mid-air refueling is a thing, so...

Circuitmike

I'm glad to hear that, because I was completely convinced that the supply rail capacitor was going to fix it and I wondered if a larger one would do the job.

Circuitmike

Clive, Could the UV leds be running a crude photocatalytic filter with that stuff? maybe some TiO2 on it, or not, but Well, they really don't know, but perhaps the original did do that!!!

I was thinking a little bit in the same direction with a inrush limiter for the HV module.

Zeedijk Mike

A very shitty product with a mighty nice casing. The case is worth way ore than the product :-) You could rebrand it as a non-spying/non-intrusive/non-listening Alexa (or what ever she is called)

In my working life I got the 'opportunity' to work on three different projects integrating our product into large mobile industrial machines being made by Chinese firms. The Chinese engineers I collaborated with, one a PhD, would feel very much at home with the design of this ionizer.

My morning therapy. I know what to do if my watch stops. A. Wind it B. Replace the battery. I go for C which is run round the planet every 24 hours and then I don't have to do A or B Simple.

Jeremy Travis

I like it when you let us enjoy your fiddling around with the tiny surface mount components.

Paul Schuur

How about an NTC in series with the ioniser module?

horrovac

Fixed it. I increased the value of the supply rail electrolytic capacitor, and it made it stable.

Big Clive

An ioniser with anti-Clive protection ? They'll have to try harder than that to keep you out.
