A hobbyist documents hands-on electronics and firmware projects, such as anodizing titanium business cards with a laser-marked finish and building an alphanumeric PIN entry routine for an Arduino device. The posts are short, informal, and mostly describe steps and experiments in progress rather than offering polished analysis.
