Hi folks, thought you might be interested in this three point shutter tester I recently developed. It's very cheap to build and uses Bluetooth to communicate the measurements to a web page that can do nice things like show averages and how far off the shutter is from being accurate.
It's all open hardware (and software) and the repository is here: https://github.com/bjpirt/shutter-tester
It uses the ESP32 as a microcontroller and so can make use of Bluetooth for communication. I've written a web app that uses Web Bluetooth built into Chrome to take the readings from the sensors and collate them all into a table so you can make averages and get a report of the calibration of all the speeds.
You can check out how this works on this demo video I put together:
