 		 #178578 - Frequent examples
Responding to: ???'s previous message
There are frequent examples on this very forum of people whose projects "work" (sic) in the nice, clean, environment of their lab - but then fail dismally when deployed in The Real World.

It invariably turns out that The Real World environment has things like (large) motors, welding plant, big relays, etc - and the problem is due to the poor design which means that the system cannot cope with the "disturbances" generated by such things.
