A 1N4001 will drop .7V for you.


This is VERY smart. I love your idea. I have about 100 of them, or
similar diodes, if not more. Now it looks like a one hour project
(time mostly spent making sure that the wire from wall wart is
securely fastened to the chop saw).

Thank you!!!!!!!!!!!

Cool idea :-) But 5% mains voltage change will be 5 V.....
I'd personally get a small 9switching) AC/DC adapter (very small ones exist,
and either combine the cables, or mount it on the tool.
