There are places like your Backyard, outdoors, a village… where your Gadgets will stop working !!!
You will feel suffocated when your Smartphone or Tablet fails to respond to your caring strokes. Your Dupey is perishing due to Undernourishment. All you need is “Electronic Solar Umbrella” which was invented by me delabs on June 1st 2014.
The Red Light is for Data Networking SmartUmbrellas using Advanced Multi-Threaded Infra Red Technology.
SUN – Smart Umbrella Networking
I just invented the SmartUmbrella – My Drone is Rushing to the Patent Office.
(Keep this confidential till my drone returns safely, the beagle boys are using Blimps with Large Magnets to capture Drones.)
I got a strange problem as i added more and more peripherals, the pc gave odd messages, “i cannot detect what you are doing” and things like that. I almost flipped trying to locate the culprit. The problem was not in any peripheral but in the USB port powering the system itself. The SMPS was not loading much. Certainly the peripherals were drawing more and the warning could have been more like “use your own power”. Computer Data Interface
I could not locate a powered USB with any vendor close by, so i built one and it works perfectly, Now it doubles up as a UPS Low Batter Indicator, by rare coincidence. If the Unregulated DC is above 7 volts, then no bugs. When i adjust the unregulated DC to the 7805 to around 6.9V, then i have a advance warning system.
Wireless USB – Wireless Extension to USB
When power fails, i keep working and listening to music from a Flash Thumb drive. When music stops, i turn of computer, the lead acid batteries gone below 20 V DC. This avoids deep discharge of my batteries. The Powered USB gets undetected when the supply falls below 4.5 probably.
