Again with the Batteries
I loaned a family member a dewalt 20v sawzall, they returned it with a completely discharged battery!!! There is hope, the battery should have internal cutoff at determined low voltage NO NO No it’s not OK to have a Li-Ion deeply discharged at all. Here is why: When discharged below its safe low voltage (exact…
Volusia County welcomes Electric Bikes on the Beach
What relief, government gets the chance to screw the public and they actually make the right decision and let it Pass. Must have to do with the makeup of the legislature. We love Volusia County and New Smyrna Beach. Of course it won’t be long before the Orlando-south Fl garbage makes their way here. Enjoy…

What’s LED Driver?
First–The terms “LED driver” and “LED power supply” are used interchangeably. Conventional AC-DC power supplies and DC-DC converters provide an output that is regulated to provide a “constant-voltage.” However, LEDs work most efficiently and safest with a “constant-current” . As a result, many new devices have been developed to provide this type of LED drive….
IOT
The Internet of things (IoT) describes the network of physical objects—“things”—that are embedded with sensors, software, and other technologies for the purpose of connecting and exchanging data with other devices and systems over the Internet. Things have evolved due to the convergence of multiple technologies, real-time analytics, machine learning, commodity sensors, and embedded systems. Traditional fields of embedded systems, wireless sensor networks, control systems, automation (including home and building automation), and…
Electrical Information US220 vs UK220
Back in the early 20th century Edison experimented extensively to find the ‘sweet spot’ voltage for incandescent lamps. That is, most lumen’s vs filament life. He settled on 110 volts as the best compromise given the state of the art on filament design. 60 cycle AC was determined by Tesla as an appropriate speed for…
