Our reader Frank created this new wireless remote for Sony cameras

Frank sent me this message:

I’ve been working on an open source project that’s a wireless remote for Sony cameras. The original spirit of the project is to bring missing firmware features like focus stacking to Sony cameras. And I managed to sort of do that, and then I went nuts implementing more and more features. It can turn the camera into a security camera with a trigger mode that supports multiple triggering sources, like sound, or you can add a laser beam break sensor. There’s even a dumb feature for bird photographers like myself, if the camera’s focus sticks to a branch instead of a bird, rapidly tapping the AF button will activate “focus frustration” mode and set the focus to minimum immediately.

This project is an open source firmware project. Anybody can download the source code and make this remote. I wrote the firmware but I did not make the hardware. This project is purely for fun and not a product and not affiliated with Sony in any way.

The firmware and instructions are on https://github.com/frank26080115/alpha-fairy/
