Hello all, Long story short: I'm modding a Netbook PC; I'm powering three different sets of LEDs from three separate USB power sources. 1. How can I create one master power switch for all three circuits? 2. Would hooking all three circuits up to one switch in parallel burnout my USB ports? I appreciate any and all constructive commentary. Also, I understand that your time is valuable and if don't want to be bothered to explain the answer I would be more than happy to receive a very brief answer which would point me in the right direction for my own research. Thank you in advance.
