A Pre-Milestone Update: Daptar (दप्तर)'s prototype hardware is almost ready!

It took around a week to hand-assemble approximately 400 tiny (1mm) individual components. I ran some basic tests on the hardware, and most functionality appears to work as expected, with minor, non-critical issues. These issues are not blocking immediate progress. Built four custom PCBs: 1. A carrier board for the
