I turned algae into a bio-altimeter and put it on a weather balloon is a business in show hn launch.

Profile

Hi HN - My name is Andrew, and I'm a high school student.This is a write-up on StratoSpore, a payload I designed and launched to the stratosphere. The goal was to test if we could estimate physical altitude based on algae fluorescence (using a lightweight ML model trained on the sensor data).The blog post covers the full engineering mess/process, including:- The Hardware: Designing PCBs for the AS7263 spectral sensor and Pi Zero 2 W.-The biological altimeter: How I tried to correlate biological stress (fluorescence) with altitude.- The Communications: A custom lossy compression algorithm I wrote to smash 1080p images down to 18x10 pixels so I could transmit them over LoRA (915 Mhz) in semi-r

I turned algae into a bio-altimeter and put it on a weather balloon is positioned in show hn launch, a segment that rewards a clear, focused offering.

The company is listed at the Show HN launch stage of development.
