Pendant with 8×8 led matrix gives many options of displaying cool stuff. Dmitry thought that common way of building pendants using 5×7 Led matrixes becomes boring and decided to improve the practice with 8×8 LED display. He wanted it to be as compact as possible and support some fancy features.
So he came up with solution where Atmega328p is soldered directly to display pins so it could scan rows and columns. Additionally to displaying images and animations he also included ability to display different intensity levels of each pixel. In order to make the construction firm, he covered back side of display with epoxy glue. Only programming header is accessible and supply wires.
