I've started this thread so not to take over the original thread this discussion started on. The original discussion was about calculating Ohms and can be found here http://www.modelrailroadforums.com/forum/showthread.php?39658-Calculating-Ohms/.
This thread is to further discuss how to utilize alterative power supplies such as an old laptop power supply to run accessories on your layout. The initial discussion was about controlling a DC motor with a power supply that has a higher volt output then the motor is rated to accept. I felt this discussion was better as a separate discussion as I can see there could be interest in this as well as I didn't want to overrun the other discussion.
I was asking if I could use a power supply that has an output of 19 volts to power a DC motor that was rated at 12 volts.
So far we just started discussion the use of a small adjustable power regulator board like those found on eBay.
We can pick up this discussion from this point.
Thank you.
Dave
