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?... ;-)
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!
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)
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
