I think that around this time I started playing around with graphic LCD displays, to used this new knowledge a build a bar based battery indicator. For this I used a st7565 display and library for graphic displays written by me, It was mostly based on adafruit library for ssd1306 Arduino library, but with some changes, I also used theirs fonts. In this project I was mostly proud of the configurable numbers of bars in the indicator, so the width of every bar was computed not hardcoded. Unfortunately I do not have any photos of this project, only Github repo that I made some time ago.
