The folks from Newer Technology got right back to me saying:
"The NewerTech Power2U's energy efficient Spring-loaded Safety Shutters turn power off to the USB ports to eliminate 'vampire' energy draw when a connecting cable is removed. Also, when a device is plugged in for charging, the Smart Power design only outputs enough charging power required by the attached device."
Wow -- it looks like they've really thought this out (more than I did at any rate)
Max, my friend, well said. I feel your pain, on the "shared suffering" part! LoL
On playing with live power "I do not recommended" but I have to admit, I have done it in the rush of the moment, on couple of occasions and have paid the price with sparks and fright!
I am with you Max on this time investment, even if it had taken a whole day to refurbish the kitchen counter to make this happen. It was time well spent to keep the queen of the house happy and on your good side ;-). I have spent days replacing, rewiring, and rearranging old fluorescent fixtures in an old warehouse to install brighter lighting for her art workshop.
Most friends tell me that a well paid electrician, could have done it for a small ransom and taken away my grief, but then again, the king would not have been flowered with complements by his queen would it?... ;-)
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
