Stepping down from 5v to 3-4.5v

[Lee Roberts]

Hi everybody,

I have a cross line laser module to fit on my machine. My bob outputs a regulated 5v but the laser can only handle 3 to 4.5v.

I imagine I need some sort of inline resistor to drop the 5v to 4.5v?

Question is what value resistor?

or is there a better way?

I know I could use 3 x 1.5v batteries but I'd like an onboard solution I can control from a macro via Mach.

Many thanks for any and all help.

Regards, Jeff

NOT FAIR !

I'v just recived mine from tiwan a few days ago, i was saving it to make a post about the idea of using one :). O Well :D

Please carry on Lee. I'm sure there are quite a few members with routers who would be very interested in how you go about installing it. The macro is an easy one to write, to be honest the biggest headache is Screen4 (or Scream4 as some call it) and getting your screenset modded but once you have it working, it has got to be one of the most usefull things to add to a router.

Anyway,

I won't utter another word on the subject, forget I mentioned it everybody, in fact i don't even know what a laser is. :D
