DIY LTCC or similar system for LT1s

Cool, I can definitely help out with this. Are you planning to use an arduino to write the program? I think that would be easy. Im not the greatest with programming but like wiring a lot so hopefully I can help

nope. I think it would be like using a sledgehammer to drive in a nail. And there is the problem of propagation delay. Counters and gates. old school. I think an arduino might get cooked under the hood. I have yet to even use one....need time to learn more about them. Coding looks easier than in my day, but if I do it by hardware, I can make more in a cheaper fashion.

I didnt know it could just be done with hardware, that makes it way easier.

Well, I had a tough time finding ICs that were not surface mount only. How annoying. Makes prototyping difficult.
Step 1.........signal conditioning. I will use a positive edge triggered flip-flop with both outputs tied to an OR gate to double the pulse count from the low res signal.
This is because I couldn't find a dual edge triggered.....anything. So, for compatibility sake, I had no choice. (counters only see the positive-going edges)

I will have to check each signal output, to make sure I don't mess up the count, with an oscilloscope. Because I'm old and forget things when my child is eating the dog's food with too much gusto. Have to complete this thought later, I have to save the dog food.
