Next-generation smartphone battery inspired by the gut
https://www.electronics-lab.com/next-generation-smartphone-battery-inspired-gut/
A new prototype of a lithium-sulphur battery – which could have five times the energy density of a typical lithium-ion battery – overcomes one of the key hurdles preventing their commercial development by mimicking the structure of the cells which allow us to absorb nutrients. @ cam.ac.uk This gets us a long way through the […]
Control an electrical appliance with your smartphone – WiFi
https://www.electronics-lab.com/control-electrical-appliance-smartphone-wifi/
Ruben Marc Speybrouck show us how to control a device using your tablet or smartphone. To achieve that he used arduino, blynk and a wemos / ESP8266 board. In this tutorial we will be making something I call a wifi controlled ac switch. (But iy also works for DC applications that are powered by a […]
