Phase 1 — Prototype

What is Auxy?

Auxy is a minimalist, portable auxiliary device that passively captures movement, audio, and visual context throughout your day. The data flows to your iPhone, where AI processes it into actionable insights.

The goal is simple: let a small device pay attention so you can focus on living. Review what matters later.

Build Log

2026-03-29 — Week 1

Wasn't able to get the whole thing working yet, but several key takeaways:

Got the battery plugged in with blue and red indicator lights for charged/charging states
Wiring was difficult — connections kept coming loose. Need soldering and alligator wires for stable power supply
The entire work requires a good setup, dedicated time, proper tools, and good focus
Visited Micro Center with Shamil — great experience, but couldn't find many parts. Will order from Amazon
Shopping list for next week: multimeter, breadboard, solder kit, alligator wires
