Outstanding work. A few years ago, I bought several 35mm film trailers with the hope of decoding the sound track. I asked a couple of my electrical engineering undergrad project students to give it a try and also tried to talk my cousin who helped build an amazing FabLab at his local high school into getting some of his students interested. No one was able to complete the project. Sometimes undergrads try to make things too complicated. Even the very bright ones. I was inspired to have students work on this because I have built a bunch of inexpensive optical communication systems that can easily transmit sound on a light beam. I have used LEDs and lasers as the light source and photodiodes, phototransistors, photoresistors, solar cells as detectors. I like solar cells because they are easy to use, work in the audio range and block most high frequency noise. I have also used a variety of signal conditioning and amplifiers, like the transimpedance amp you used. Excellent choice. If you want to learn more about these experiments, I can add more info in the comments. For now, I just mentioned these things to show you my interest. Again ... great job.

I looked around and could not find anyone using it for an audio output. Can you tell me how you hooked it up to your audio amp?

@emilyvelasco915

I think it's very rare for 8mm film to come with an audio track, and the few that do often use a magnetic track similar to the tape in an audio cassette. If you have 8mm film with an optical audio track, this would work, provided you adjusted the dimensions

Great build. If you really want to do something fun you can actually draw your own optical track onto film and get sound. the guy most famous for doing this was Norman McLaren (films like pen point percussion and Dots). I've done it myself, 35mm film works best cause of the size. you draw with a dip pen and Windsor and newton black Indian ink onto undeveloped film emulsion, let it dry (draw dots and lines where the optical track would be.) develop it in black and white chemistry like normal film and at the end. the ink will've washed away and left behind a silhouette of it's shape on the film itself. It ends up sounding really weird especially when you try and emulate normal looking sound waves by hand.
