What I'm building

3d-print-workflow · AI-assisted 3D printing, from model to printer

A workflow for any printer, with a tested Bambu Lab track: a monitor that sends phone alerts, a Studio-to-Orca profile converter, a conductor skill that walks the cycle in order, and docs.
Stack Python, Make, OrcaSlicer, Bambu Lab P2S
Repo lavinialencar/3d-print-workflow
Demo lavinialencar.com.br/en/lab/3d-print
smart-coffee-scale · pour-over scale that guides every pour (concept)

A coffee scale that builds the recipe from the taste you want and guides the brew on its own screen: when to pour, how much, when it is done, and what to change next time. Designed and simulated, prototype next.
Stack ESP32-S3, HX711, 2.8" IPS, Fusion, PETG

ember-template · personal finance for Brazilian bank accounts via Open Finance

A personal finance pipeline you run on your own machine: it reads statements and card bills through Open Finance (Pluggy), classifies every transaction with rules you control, sends alerts to your phone and builds a local dashboard. Encrypted backup, no personal data in the repo, offline demo in two minutes.
Stack Python (stdlib only), Postgres, Docker, n8n, ntfy
