This seems to me that your experiment failed due to thermal failure cased by insufficient cooling and not the part itself..You stated yourself that the part failed due to thermal expansion (insufficient cooling). But it’s still a valid experiment with valid results. And you show that it’s up to the designer (or designers) to design the entire product, which includes sufficient cooling. This is one area where home designs fail – a lot.

If you had the choice between two identical-looking boards, with the same pictures, and review ratings, would you spend an extra 20¢ on the more expensive one? That twenty cents really adds up, you know- if I was buying 1,000 ESP-12 boards, for example, that would be two hundred dollars saved, and you would be pretty happy with yourself. That is, if it works. Otherwise, you feel really dumb.

No I don’t want one, because I have a computer museum and I don’t feel the need to instant-wipe all my floppy disks at the flip of a switch.

I think most people recommend having the PSU switched off at the wall. That way it should be pretty much safe, but there is still the other issue you mention.

Unfortunately, by in large, the comments for this article were unnecessarily negative, and downright factually inaccurate.

A REAL Fotek is a good brand ….. however some dishonest shops in China are turning out fakes by the thousands ,,,,, I got burnt by a fake Fotek 25A DC SSR for a printer a couple of years ago and the 2nd or 3rd time I used it the MOSFET went up in smoke although nowhere near this spectacularly …. I ended up replacing it wtih a 100A Fotek that I could ascertain was genuine and it’s been working ever since

From instances I have seen in forums of melting outlets, they aren’t dopes. The bottom line is 120 V is terrible for power delivery and it is really unfortunate that US adopted that level. Often times it is the outlet failing even when used in specs, either from poor install, cheap outlet, etc.Also, they get damaged, it might have been fine when someone started using it, but they miss the damage.

No, ebay removed the ability for sellers to leave negative feedback years ago. Fun fact – the majority of an ebay sellers score these days (not the % positive feedback, but the score used for determining search rankings etc) is determined by the % of orders that are received on time and without a ebay ‘case’ (return, etc) being opened.
