increase the resistors by a factor of 100 or so and add a very small cap across the lower one. The cap inside the ADC is absolutely tiny, pF at best. So a 100nF cap would easily do the trick and supply the voltage as required.

Interesting. I decided to look at reviews the usual way if I was going to use one of the company’s. Chose “mr emergency” and pretty much 4.6 out of 5 from just the google search. Drilled down to product review and it looks pretty good, too good, suspiciously good in fact.

Check on the “people” giving these reviews and they all have a single review and every one reads like it was professionally written. AI perhaps ?

Go to the 1 star reviews and suddenly it’s a different picture.

Good lesson, thanks for the heads up.

Damn, I was only thinking last night how I wanted a Polly Waffle. Guess I’ll add fantales to the list. Nearly bought some in Coles last week as they were half price.
