#1 about 4 min

Building pet projects for fun and learning

How creating various software side projects fosters personal development and new technical skills.

#2 about 3 min

The origin of the bottle cap collection

Collecting and trading bottle caps served as a way to build friendships as an immigrant.

#3 about 3 min

Automating collection management with computer vision

Using computer vision helps identify whether a specific item already exists in a large physical collection.

#4 about 3 min

Applying Hough transform for circular object detection

Initial attempts to find circular objects in images using Hough transforms led to overlapping and false positives.

#5 about 9 min

Improving detection accuracy with image pre-processing

Resizing, color reduction via K-means clustering, and blob detection significantly reduce noise for machine processing.

#6 about 2 min

Refining object detection and handling overlapping

Calculating approximate blob sizes helps configure Hough transforms to filter out overlapping false positives.

#7 about 8 min

Identifying objects using vector databases and pre-trained models

Generating vector embeddings with MobileNetv3 and querying Pinecone enables fast and accurate similarity matching.

#8 about 4 min

Deploying the app and managing user feedback

Releasing a Flutter and Firebase app to a community brings valuable bug reports and user donations.

#9 about 3 min

Shutting down the project and evaluating success

Unexpected cloud billing changes forced the project's closure, but the technical and personal insights remain valuable.
