Yes I would put a fuse in front of R1 But it's a nice energy meter And we resale power
That idea would be simple way to show the renters there power use.

The supply is a nice idea for what it's being used for And I sure people will like
to read it. There a lot of people that ask about this kind of thing

And there a lot of Transformerless Power Supplies about haft of the supply's that run things like network router used them. http://www.eeweb.com/design-articles/tr ... capacitive

Moderator's Note:

In the interest of safety, comments have been added regarding this power supply design and transformerless designs in general. This type of supply is fine where it is totally enclosed in an insulated housing. Power supplies of this type are at line voltage potential and can be fatal if parts are touched. Understand the hazards before constructing a supply of this type.

Several messages in this stream have been deleted; they had to do with warnings about the power supply shown above.
