A high-speed laser camera trigger for under $2

In plain words

This is a minimalist laser camera trigger designed for high-speed flash photography, responding in microseconds. Built with a strict $2 budget constraint, it strips away configurable features to prioritize speed and simplicity. The device is intended for photographers and engineers who need to capture fast-moving events triggered by laser sensors, prioritizing performance over complexity.

From the sources

Testing a high speed flash means I need an extremely fast laser camera trigger. And by fast, I mean microseconds (millions of a second). Having recently finished working on Triggertrap Ada, which is the highest-performance, most feature-packed camera trigger out there, I wanted to go the opposite direction and make the absolute minimal laser trigger. I didn’t care about configurable delays or thre

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
