Parallel Port breakout boards, motherboards, and dedicated accessories / Re: stealing 5v for laser pointer
« on: November 01, 2016, 03:22:43 AM »
Apart from a few small resistors across my inputs and the outputs to the drive step and dir I don't think there is any thing else on the PC 5v.
I do have a PMDX 109 in the mix but I think I set that up to take 5v from PSU via the ESS so no worries there. The laser has 5mw output so sounds like i have a winner on the 5v pc line.
Cheers for the help!
