Build a Single Camera 3D Scanner (Photogrammetry). by lparkin

Description

I want to see how fast I can develop a single-camera (pi camera module v3) rig with a stepper motor controlling a turntable that rotates the model being scanned. The trick here is not to be super fancy with 100's of sensors and data inputs, quite the opposite. I want to see how accurate I can scan objects into 3D-printable models using only a camera and as many fixed and known parameters as possible.

Speed to be augmented with agentic AI coding companion. As it stands, I have a 3D printer, pretty much all the electronics I need.

Goals

• Design and print working/workable camera rig
• Design and print working/workable turntable (considering printing my own cylinder-style bearings as well)
• Assemble rig components into MVP assembly
• Develop application that can hook into existing tools, or leverage a library like openCV, to process 2D images into a 3D model.
• Iterate until models are good enough to 3D print.

Recipes catalog and calculator in Rails 8 by gfilippetti

My wife needs a website to catalog and sell the products of her upcoming bakery, and I need to learn and practice modern Rails. So I'm using this Hack Week to build a modern store using the latest Ruby on Rails best practices, ideally up to the deployment.

TO DO

• Index page
• Product page
• Admin area -- Supplies calculator based on orders -- Orders notification
• Authentication
• Payment
• Deployment

Day 1

As my Rails knowledge was pretty outdated and I had 0 experience with Turbo (wich I want to use in the app), I started following a turbo-rails course. I completed 5 of 11 chapters.

Day 2

Continued the course until chapter 8 and added live updates & an empty state to the app. I should finish the course on day 3 and start my own project with the knowledge from it.

Hackweek 25

For this Hackweek I'll continue this project, focusing on a Catalog/Calculator for my wife's recipes so she can use for her Café.
