#90 When GOOD 😇 components go BAD 👿

Many of us Arduinites are blessed to be able to order items from the Far East, where components are plentiful and cheap. What we all hope, of course, is that cheap does not mean cheap-and-nasty, and for the most part the items are all fine and fit-for-purpose.

But occasionally good components go bad, sometimes through poor quality control (QA) or poor circuit design or even poor component selection.

So we must accept that some component modules are built down to a price (not up to a particular standard) so that they can compete for our Dollars (or Pounds, Euros or Roubles). Price is king in most non-commercial environments (that's us hobbyists!) so we have to accept that failures can (and do) occasionally happen.

Watch the video for some examples of recent failures, one of which could have been particularly nasty! And I've learned my lesson that sometimes it pays to pay a bit more for critical components that have actually got some QA applied to them. Live and learn, hey?
