Unlock Passwords With Tinyml-based Digit Recognition
vilaksh01 May 06,2022
Story? IntroductionThe active development of smart gadgets with touch interfaces is trending nowadays. Lately, I've just got carried away by searching for different ways to solve digit recognition tasks using the machine learning approach (this is my third project on this topic).This time I made a solution for a simple digital lock with a 4-digit pin code added. The device initially allows you to set a custom 4-digit PIN which could be later reused to unlock the device.This simple example can be...

Flux Capacitor PCB badge V3
Arnov sharma Jan 12,2022
Hey Everyone what's up!So this is my FLUX CAPACITOR Badge version 3 which is a replica of the actual flux cap which was in back to the future movie.I've prepared its V1 a few months ago, back then, it had a couple of Throughole componenets which included the main MCU and Slide Switch, so I switched to all SMD components to make this project easy to assemble.Like its previous version, this edition requires 2.6V at 0.0069A which is around 0.017 Watts or 0.000000000017 GigawattsIt uses a CR2032 3V ...
