If the project uses a _very_ low, constant current use a resistor
(cheapest).
If the power-consumption is _very_ low, but not constant, add a zener-diode
over the project.

But remember, a current of 10 mili-Amp will generate 10mA * 110 V =
1.1 Watt's of heat in your resistor !

An other possebility is to use a condensator as a AC-Resistor.  You will
have
to do some math to find the right value though ...
