G gvi70000 Member Nov 11, 2009 #21 i think i've got it What do you think? I need something similar for the photo diode sensor. From what i can find on the internet, i don't understand well the trans impedance amplifier, so maybe some one will explain it to me on a beginner level. the link from old post https://www.electro-tech-online.com/attachments/canon_eos450d_remotecontrol-jpg.34745/ Attachments CompleteSoundTrigger.PNG 35.9 KB · Views: 209 Last edited: Nov 11, 2009
