Show HN: AetherCam, a video recorder focusing on audio

Fri, 02/20/2026 - 2:22pm

Hey everyone,

I wanted to share one of my passion projects that I've been working on for the past year. AetherCam is a video recording app that allows you to apply effects to the audio track in real-time. You can boost volume, add reverb, compressor, eq, and delay. Everything on the fly.

The idea for AetherCam came to me when I was recording myself playing guitar and thought that the part that I came up with would sound really cool if there was some reverb applied to it. Day after that "revelation", I sat down and started coding the app. I had some prior experience with AVFoundation and Core Audio, as I worked in a startup that dealt with audio for a brief moment, so knew what I needed to get the ball rolling, but still, the effects were one of the toughest part to write.

I already have version 1.1 in the works that significantly improves the reverb engine. Would love to know what you think! :)

Instance segmentation model that extracts 3D geometry from 2D floor plans

Fri, 02/20/2026 - 2:17pm

Hey HN,

I am an ML Engineer and a full-stack software engineer. For the past few weekends, I have been working on a pipeline to solve a PropTech problem: turning messy, highly occluded 2D floor plans into clean, structured data for 3D extrusion. Originally demoed for a firm hiring for the role.

The Problem: If you try to use standard object detection (bounding boxes) or basic OCR (tested Qwen, DeepSeek) on architectural plans, it fails instantly. Walls intersect, doors swings and dimension lines heavily occlude the actual structures.

The Stack & Architecture: I built an instance segmentation pipeline that relies strictly on pixel-perfect masking to pull the geometry.

The Backbone: Swin Transformer + Detectron2.

Model trained on 1024X1024 images, with RTX 4090

Inference: Inference on CPU <10s.

Output: Clean JSON

Demo Performance: 67.1% AP50 for instance segmentation masks, and a 38.2% AP across the strict 0.50:0.95 IoU thresholds.

Vector Clean-up (The JSON Payload): 3D engines don't want pixel masks; they want math. The pipeline passes the raw predictions through Shapely to run boolean unions on intersecting walls, outputting clean, mathematically sound 2D polygons in a structured JSON payload.

Why am I posting: A lot of virtual staging and architectural startups have beautiful Three.js rendering engines, but they still rely on human data entry to get the base data. I built this specifically as an extraction engine to sit underneath those UIs.

If you are in the PropTech or you are building a product that could benefit from embedding this model, I would love to chat.

Show HN: Vibe coded iOS workout app with Apple Watch support

Fri, 02/20/2026 - 1:31pm

I spent a month to put together a workout app without writing a single line of code by hand. It's on par with many apps like Fitbod or Fitness AI. Got approved on iOS App Store. Let me know if you want free access, only thing I ask is to give me genuine feedback and one feature you would like to see. I will be asking Codex/Claude to rank the top features and implement it.
