This shutter speed tester is based off of Cameradactyl's shutter timer, modified to display on an I2C SSD1306 128x64 display. It was forked to run automously without a computer connected.

You need a shutter speed tester, and luckily for us, [Stuart Brown] has one. There are no sharks involved in this build, but it does rely on laser diodes as a light source.

Enrico takes us behind the lens of his PONF camera project. In this installment he is hacking the shutter mechanism of a Cannon 60D.

When the shutter on the camera is released, the shutter speed can be measured and displayed on the OLED screen. An Arduino naturally handles all the computational duties.

The Phochron XA Film camera shutter speed tester has been designed to offer a quick and accurate handheld tester that displays both numerical timing and a scope-like waveform.

Kevin Kadooka has this month finished his Lux open source camera that he has been working on, with a goal of building a fully-fledged camera, using just easily purchased off-the-shelf components ...
