Solar BMS (Solar Battery Management System) is a solar charge controller designed to replace the Lead Acid solar charge controllers most people use today in Offgrid, RV, Boats and multiple other applications with 12V and 24V systems. Solar BMS can be used with 3 up to 8 Lithium cells (any type) or supercapacitors. The new […]

This simple project is intended to help you in answering the lifelong question “Does this battery have any juice left?”. Although popularity of single cell batteries (such as AA, AAA, C and D cell) is diminishing, there are still many small devices like TV remotes, flashlights, and other small portable electronics that run on these

The terahertz (THz) region, which is based on 1THz frequency, separates electronics from photonics and has been difficult to access for ages. Semiconductor electronics cannot handle frequencies equal to or greater than 100GHz due to various transport-time related limitations. In other hand, photonics devices fail to work below 10THz as photon’s energy significantly drops to thermal energy. Terahertz
Story Idea and reason One of my long running projects, “lights off” comes from the need to know : “Did I turned off my bathroom light?” ; “This light are on for too much time, I wonder how much I am paying for it”. Without wanting to rewire my house, I came up with designing

I have salvaged so many old lap-top batteries ( 18650 ) to reuse them in my solar projects.It is very difficult to identify the good cells in battery pack.Earlier in one of my Power Bank Instructable I have told, how to identify good cells by measuring their voltages, but this method is not at all

Researchers at the University of Warwick in the UK have developed sensors which measure the internal temperature and electrode potential of Lithium batteries. The technology is being developed by the Warwick Manufacturing Group (WMG) as a part of a battery’s normal operation. More intense testing, including evaluation for Faster Charging, has been conducted on standard
Cloom, a reliable wire harness, and cable assemblies manufacturer, today published a “Cloom-Battery Cable Cuide.” It has four chapters that cover some useful terms about battery cable assembly knowledge. “The Cloom R&D team adapts quickly to the changing market needs. The R&D team helps customers in developing the design, advising on the material, developing new

We love the Arduino board and it’s prototyping platform . It makes the complete prototyping process smooth and enjoying with the help of it’s add on such as Arduino IDE and a huge community support.But sooner or later you will find that the specifications provided by the arduino boards is not enough . And then

“Hello, hello. I am calling from a battery-free phone.” Vamsi Talla’s words in a cluttered lab at the University of Washington in Seattle are barely audible through pops and static. But the fact they can be heard at all, on a nearby Android smartphone, is revolutionary, because Talla’s own cell phone has no battery at all.

Renesas Electronics Corporation announced the successful development of a new low-power SRAM circuit technology that achieves a record ultra-low power consumption of 13.7 nW/Mbit in standby mode. The prototype SRAM also achieves a high-speed readout time of 1.8 ns during active operation. Renesas Electronics applied its 65nm node silicon on thin buried oxide (SOTB) process to develop this
