The circuit I am using is here: http://www.baytan.org/prak/shutter.html The only difference is that I added a switch. The squiggles were constant and therefore noise. I have done some further testing and did get it to work, however, it is a little strange. I have to use the "line-in" input on my computer and set Audacity to "aux, line-in 2". Using the mic input does not give a signal. Also, the switch on the tester must be in the off position. This makes no sense, I know, but I'm sure I tested the switch and marked the proper "on,off" positions. I'm just happy that it is working, so I won't ask too many questions! I tried the outfit with different light sources and it works fine and seems to be very precise. I even tried a TV remote and it shows a very strong signal, however the signal is in pulses, so I don't know if it would be easy to measure the duration. |
