Original demo and idea: http://www.youtube.com/watch?v=s1eNjUgaB-g
My video info:
Philips PM3450 osciloscope.
PC Ibm thinkpad 600 - 233mmx
Sound card is much critical. My K6-II 500 with poor onboard sound car as a very poor performace.
Strangely, i have a much noise with a small signal level. Probably problem is quality of sound card.
Video taked by sony DSC-P92 and edited with VirtualDub.
p.s. Sony DSC-P92 is not a good camera for this... lost focus frequently, argh!
Enjoy this! :)
your camera is fine, just disable auto-focus next time. thanks for the post! :)
