Hello Guys
I was wondering if someone could help me with a circuit?
I am trying to read the inputs from a slot car track to a computer ADC. My attempts to directly connect the track have resulted in dead pins on the computer.
My initial attempt being
I suspect the attempt to connect Computer and slot track GNDs was the root of my problem.
How can i introduce a DC-DC converter which will isolate the grounds?
Any help gratefully received.
It is important the output follows the input proportionally.
I know this would be fairly trivial if the input was AC, unfortunately its not and i really need to isolate the output.
