Could Sodium-ion Batteries be a Replacement for Li-ion Batteries?
https://www.electronics-lab.com/sodium-ion-batteries-replacement-li-ion-batteries/
In early 1990s lithium-ion batteries started gaining popularity as a substitute for nickel-cadmium batteries. They have higher energy density, low self- discharge, and low maintenance, but it was soon found that they have short life span, unstability which causes security concerns and creates the need for protection circuits (to maintain it within safe limits), and […]
Using an MMA7455 accelerometer with an ESP32 board

Cameron Coward @ blog.hackster.io writes: Like most connected technology these days, near-field communication (NFC) is susceptible to hacking. By its very nature, NFC is normally accessible by anyone nearby. NFC, as it was originally intended, is designed to provide data wirelessly to any nearby readers without requiring a power source of its own. Fortunately, N-O-D-E, […]
Transistors- The 70-year-old invention that changed the world
https://www.electronics-lab.com/transistors-70-year-old-invention-changed-world/
Its been 70 years since the fundamental building block of electronics was created, and it has been getting smaller, and better since then. The invention that won the Nobel prize for John Bardeen, Walter Brattain, and William Shockley in 1956 revolutionized electronics and made it into the IEEE milestone list. Before 1947 computers used vacuum […]
