I did it once, and mine worked, though not spectacularly well. The waveform is pretty sloppy, and usefulness declines as shutter speed rises. It's very good on slow speeds. Since you have already tested the computer end, I'd make sure all your polarities and connections in the tester are correct, try switching them around even if you think you shouldnt, and if that doesn't do it, try another phototransistor. I robbed one out of an old mouse for mine. Don't forget too that the signal is probably going to be pretty weak, so make sure you crank up the gain in your sound input. |
