R2D2 Mini Edition
Arnov sharma Feb 23,2022
So here's something special, A Mini R2D2 PCB that speaks ASTROMECH.Astromech is a fictional language in the star wars franchise consisting of whistles and beeps.This Mini R2D2 that I made is a Keychain.Its brain is an Attiny85 and is powered by a CR2032 Coin Cell holder.I was inspired by this Instructables- https://www.instructables.com/R2D2-Sound-Generator/MarceloLarios made a simple Arduino Uno setup that produces random beeps every 3 seconds.I took the concept an...

PCB Necklace V1
Arnov sharma Feb 01,2022
Hey Everyone, so here's something cool.A PCB Necklace or Pendant powered by an Attiny13A.The goal here was simple, to make a small Blinky board that can be attached to a chain so we can wear it like a locket or pendant.There are a total of 24 LEDs in this Pendant, I've divided LEDs into pairs of 4.This means 6 LEDs are connected in parallel and they are driven by a single AO3400 N channel mosfet. there are a total of 4 of these which control 6 LED segments each.These 4 MOSFETs are then controlle...

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 ...
