shutter speed tester proto (1)
Here's a couple of progress pictures of my shutter speed tester prototype. The first pass PCBs are done. The color LCD had been picked and software is now being written.
I am confident that I can display the actual waveform of the light as seen by the photo diode much like an oscilloscope waveform.
The view with the lid off shows the small PCB with the two photo-diodes that are used as detectors. Two will be used for curtain shutters, only one will be used for diaphragm shutters.
You can see the plug in light source that will be used to give a controlled light beam for the shutter under test. It can also be used to calibrate the sensors.
Running on 2 AA batteries, it will feature auto shut off and menu based screens.
Hope to have a kickstarter going when I get the software going and fully prove the concept.
