Photodiode array project rev1

It’s 3am what better time to fiddle around with photodiodes! I received the photodiode array boards today and decided to have a quick play around. With a 10M feedback resistor they’re only outputting about a volt, this will work but the OpAmps have 12v rails so I might change the feedback resistor at some point. Too quickly test the board I soldered 4 of the Opamps in and wired the output directly to some LEDs, later I’ll look at acquisition options, including the 8 channel ADC board I’ve made. For a demo and some rambling see the video below:
