Rechargeable batteries with nanowires last forever

Rechargeable batteries with nanowires last forever

Electronics News Updates / By

University of California, Irvine researchers have invented nanowire-based battery material that can be recharged hundreds of thousands of times, moving us closer to a battery that would never require replacement. The breakthrough work could lead to commercial batteries with greatly lengthened lifespans for computers, smartphones, appliances, cars and spacecraft. Scientists have long sought to use […]

ulibSD – a library for use SD cards in SPI mode with uControllers

Electronics News Updates / By

ulibSD It’s a library for use SD cards in SPI mode with uControllers, entirely writtenin C. This library can work with SD cards and also has the possibility to emulate the behavior in a PC file (GNU/Linux) using the macro _M_IX86. It’s for debugging purposes. The data transfer is oriented to 512 byte size, remember
