Show HN: How I built my connected smart shower
In this technical retrospective (2016), @drewry shares practical architectural lessons learned from running, scaling, or migrating production software under lean constraints.
Core Principles for Independent Builders:
Defaulting to simpler architectures (such as monolithic frameworks, SQLite, or managed VPS) prevents early engineering bankruptcy.
Evaluating true compute and egress costs reveals that high cloud bills can often be slashed by 80%+ through judicious re-platforming.
Code you write at 2 AM as a solo engineer must be easy to debug six months later without complex microservice dependencies.
Community Debate Themes:
HN engineers debated the tradeoffs between cloud convenience and raw server economics, database indexing strategies, and resisting premature architectural complexity.

Seems like the start of a pretty slick setup. It would be really cool to add an IR frame and get a multitouch UI working with this sort of like this setup: http://www.instructables.com/id/Interactive-Multitouch-Display/ Might be easier for navigating rather than using a mic?
