Re: Digital Shutter Speed Tester

[Niko Koskela]

I have built a shutter speed tester like this one:  
http://davidrichert.com/sound_card_shutter_tester.htm

I first found it on an German site, but can´t find that site anymore. I 
have built mine with 3 phototransistors, so i can check the curtain 
travel speed as well. Cost less than 10EUR. I have repaired a few 
Spotmatics an SV and a KX using this meter.

Accuracy is quite good enough. When i overhauled my first Spotmatic, i 
needed to get a different high-speed cam from a Pentax repair shop. 
While visiting there, i told the guy which kind of meter i was using. He 
said i could visit there to check if my meter was any good. I don´t 
remember the exact accuracy of the values anymore, but he told that if 
it was a camera overhauled by himself, he wouldn´t try to make it 
anything more accurate.

Can´t help with measuring the DSLR shutter testing, which was the 
original topic...
