Back in April 2013, I was a young developer who joined a 2-day hackathon in Jakarta with an idea that felt far too ambitious to finish.
I left as a NASA International Space Apps Challenge Champion. 🏆
The project was called OpenTEC. TEC stands for "Total Electron Content".
The idea was to explore whether an earthquake prediction system could be built using Arduino, a GPS receiver, and Professor Kosuke Heki's ionospheric precursor theory, the hypothesis that the Earth's ionosphere may show measurable anomalies before major earthquakes.
At the time, I did not finish it.
The hackathon ended. Life moved on. But that unfinished prototype never really left my mind.
For 13 years, OpenTEC stayed somewhere in the background of my thoughts.
Then Artemis II launched 🚀 and something in me shifted. Watching that rocket leave Earth made me ask myself: what exactly am I waiting for?
Today, with open-source hardware, far better GPS data, and much stronger ML models, it feels worth revisiting this old idea seriously.
Because if there is even a small chance that better detection could help provide earlier warning and save lives, then it is worth exploring.
To everyone who was in that room in Jakarta in 2013, thank you. You were the spark.
