Re transformerless offline power supply.

As well as the "always use an isolating transformer ..." warning it would be
worth adding, right next to the circuit, a warning along the lines -

WARNING - In transformerless circuits such as this one ALL components
including the equipment powered should be treated as being at full mains
voltage at all times. While the output circuit is designed to be nominally
at earth potential, changes in the manner of connection or incorrectly wired
mains power outlets may result in the whole circuit being "live". Failure to
treat the circuit as live at all times may result in death.
