It is about 4 x 5 cm in size. The electronic parts are integrated into the design or glued to the back. To add some details, we used a white paint marker. <p> Visit my <a href="https://github.com/pixelEDI/attiny_birthdaypin">GitHub </a>site for the source code of this project. </p> <p> You like it?
