I am making a shutter speed tester for my engineering class. I think I’m going to use a photodiode and a voltage comparator, and a PIC 32 or something. I’d be interested to see how you made yours, could you provide a schematic for? It’d be greatly appreciated if you still have it somewhere. Thank you!
You could use the artwork to generate a schematic or look at my Apple II version which has a slightly more complicated implementation. The schematic for the Apple II version is on this page (the LM319 was omitted in the microcontroller version).
What is the cost for the SCELBI 8H bare PCB set?
300 dollars, but you will need to give me a few weeks to complete checkout.
