Arduino Keyboard v5.0

Originally I was thinking about laser cutting an acrylic case for the keyboard, but later decided to just use some cardboard and super glue (and some tape…) to make a rough looking case. I’m a complete noob at soldering. The soldering process took me about 8 hours, and designing & making the case took me one and a half. The dimension of the case is roughly 17.4 cm * 6.2 cm * 2.3 cm (front hight) ~ 3.6 cm (back). Under the protoboard is an Arduino and a 9V battery. I think the next step for this project is to figure out a way to replace the Arduino with just a single ATmega328 chip, making the keyboard even cheaper and thinner.

    Very cool!! I loved this project when I first saw it on Show & Tell. It has evolved much from that. If I may suggest, build an Arduino on a breadboard ( ) if you don’t want or don’t have time to practice your soldering skills to free up your Uno. I’ve made 3 Arduinos on perfboard & it is GREAT soldering practice. Now I’m gonna have to make another to build this keyboard! I love it!! 🙂
