FDK CORPORATION will begin sample shipment of oxide based all-solid-state battery using high electrochemical potential cathode material “lithium cobalt pyrophosphate (Li2CoP2O7)” which was jointly developed with Fujitsu Laboratories Ltd. February 2017. While applications using various batteries such as IoT devices and wearable devices expand and progress, the specifications required for batteries are becoming increasingly diverse,

Rather than just giving an off-the-shelf toy gift, I wanted to give my nephews a unique gift that they could put together and (hopefully) enjoy. While the Arduino code for this project may be too difficult for them to understand, the basic concepts of input, output, loops, and conditions used in this code could be
Summary Last several times when i buy thermometer, i saw that there is almost always difference in the values. My task was to follow the temperature and the humidity inside my baby’s room. Also there was issue reading the values from 2-3 meters range on the most thermometers and i needed to stand up to
Developers, makers and enthusiasts looking for a ESP32-S2 development board may be interested in the MorphESP 240 created by the development team at Morpheans. The MorphESP 240 is an easy-to-use, Arduino- and CircuitPython-compatible, open hardware ESP32-S2 dev board with a built-in high-resolution, IPS-color display. The MorphESP 240 is now available to purchase from the Crowd
[Martin Fasani] has set out to build a beautiful low power E-Ink Calendar he can hang on his wall. But perhaps more importantly, the work he has done makes it easier for everyone in the future to have a e-ink display. Many battery-powered e-ink projects connect to some server, download a bitmap image, display the new
New co-authored paper demonstrates potential ten-fold energy density increase over existing lithium-ion battery technologies. Scientists from Honda Research Institute have collaborated with researchers at California Institute of Technology(Caltech) and NASA’s Jet Propulsion Laboratory to develop a new battery chemistry that enables the use of materials with higher energy density and a more favorable environmental footprint than current battery technologies. The
RESEARCHERS DEVELOP NEW BATTERY CHEMISTRY WITH 10X MORE ENERGY DENSITY OVER LITHIUM Continue Reading
We suppose it’s a bit early to call it just yet, but we definitely have a solid contender for Father of the Year. [DIY_Maxwell] made a light-up hockey game for his young son that looks like fun for all ages. Whenever the puck is hit with the accompanying DIY hockey stick (or anything else), it lights up
This Instructable is a continuation of my earlier weather station project. It was quite popular on the web, people around the globe made their own by following it and given valuable feedback for improvement. By taking consideration of the comments and Q&A section of my earlier project, I decided to make this new version Weather Station. I
